Cannibalism 

From Wikipedia, the free encyclopedia 

Cannibalism (from Caníbales, the Spanish name for the Carib people,[1] a West Indies tribe formerly well known for their practice of cannibalism)[2] is the act or practice of humans eating the flesh or internal organs of other human beings. It is also called anthropophagy. A person who practices cannibalism is called a cannibal. The expression "cannibalism" has been extended into zoology to mean one individual of a species consuming all or part of another individual of the same species as food, including sexual cannibalism.

Cannibalism was widespread in the past among humans in many parts of the world, continuing into the 19th century in some isolated South Pacific cultures, and to the present day in parts of tropical Africa. In a few cases in insular Melanesia, indigenous flesh-markets existed.[3] Fiji was once known as the 'Cannibal Isles'.[4] Cannibalism has been well documented around the world, from Fiji to the Amazon Basin to the Congo to Māori New Zealand.[5] Neanderthals are believed to have practiced cannibalism,[6][7] and Neanderthals may have been eaten by anatomically modern humans.[8]

Cannibalism has recently been both practiced and fiercely condemned in several wars, especially in Liberia[9] and Congo.[10] Today, the Korowai are one of very few tribes still believed to eat human flesh as a cultural practice.[11][12] It is also still known to be practiced as a ritual and in war in various Melanesian tribes.[13] Historically, allegations of cannibalism were used by the colonial powers to justify the subjugation of what were seen as primitive peoples; cannibalism has been said to test the bounds of cultural relativism as it challenges anthropologists "to define what is or is not beyond the pale of acceptable human behavior".[14] Cannibalism is rare and is not illegal in most countries.[15] People who eat human flesh are usually charged with crimes other than cannibalism, such as murder or desecration of a body.[15]

Cannibalism has been occasionally practiced as a last resort by people suffering from famine, including in modern times. A famous example is the ill-fated Westward expedition of the Donner Party, and more recently the crash of Uruguayan Air Force Flight 571, after which some survivors ate the bodies of dead passengers. Also, some mentally ill people obsess about eating others and actually do so, such as Jeffrey Dahmer and Albert Fish. There is resistance to formally labeling cannibalism as a mental disorder.[16]

Overview

The Carib tribe in the Lesser Antilles, from whom the word cannibalism derives, acquired a long-standing reputation as cannibals following the recording of their legends in the 17th century.[14] Some controversy exists over the accuracy of these legends and the prevalence of actual cannibalism in the culture.

The spread of human cannibalism (anthropophagy) in the late 19th century.

A well known case of mortuary cannibalism is that of the Fore tribe in New Guinea which resulted in the spread of the prion disease kuru.[17] Although the Fore's mortuary cannibalism was well documented, the practice had ceased before the cause of the disease was recognized. However, some scholars argue that although post-mortem dismemberment was the practice during funeral rites, cannibalism was not. Marvin Harris theorizes that it happened during a famine period coincident with the arrival of Europeans and was rationalized as a religious rite.

In pre-modern medicine, an explanation for cannibalism stated that it came about within a black acrimonious humour, which, being lodged in the linings of the ventricle, produced the voracity for human flesh.[18]

In 2003 a publication in Science received a large amount of press attention when it suggested that early humans may have practiced extensive cannibalism.[19][20] According to this research, genetic markers commonly found in modern humans worldwide suggest that today many people carry a gene that evolved as protection against the brain diseases that can be spread by consuming human brain tissue.[21] A 2006 reanalysis of the data questioned this hypothesis,[22] as it claimed to have found a data collection bias, which led to an erroneous conclusion.[23] This claimed bias came from incidents of cannibalism used in the analysis not being due to local cultures, but having been carried out by explorers, stranded seafarers or escaped convicts.[24] The original authors published a subsequent paper in 2008 defending their conclusions.[25]

Reasons

In some societies, especially tribal societies, cannibalism is a cultural norm. Consumption of a person from within the same community is called endocannibalism; ritual cannibalism of the recently deceased can be part of the grieving process,[26] or a way of guiding the souls of the dead into the bodies of living descendants.[27] Exocannibalism is the consumption of a person from outside the community, usually as a celebration of victory against a rival tribe.[27] Both types of cannibalism can also be fueled by the belief that eating a person's flesh or internal organs will endow the cannibal with some of the characteristics of the deceased.[28]

In most parts of the world, cannibalism is not a societal norm, but is sometimes resorted to in situations of extreme necessity. The survivors of the shipwrecks of the Essex and Méduse in the 19th century are said to have engaged in cannibalism, as are the members of Franklin's lost expedition and the Donner Party. Such cases generally involve necro-cannibalism (eating the corpse of someone who is already dead) as opposed to homicidal cannibalism (killing someone for food). In English law, the latter is always considered a crime, even in the most trying circumstances. The case of R v Dudley and Stephens, in which two men were found guilty of murder for killing and eating a cabin boy while adrift at sea in a lifeboat, set the precedent that necessity is no defence to a charge of murder.

There are numerous examples of murderers consuming their victims, often deriving some degree of sexual satisfaction from the act of cannibalism. Notable examples include Albert Fish, Issei Sagawa and Jeffrey Dahmer. These individuals are usually considered to be mentally ill, although the compulsion to eat human flesh is not formally listed as a mental disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM).[16] Cases of autophagia, or self-cannibalism, have also been reported.

Myths, legends and folklore

Cannibalism features in the folklore and legends of many cultures and is most often attributed to evil characters or as extreme retribution for some wrong. Examples include the witch in "Hansel and Gretel", Lamia of Greek mythology and Baba Yaga of Slavic folklore.

A number of stories in Greek mythology involve cannibalism, in particular cannibalism of close family members, for example the stories of Thyestes, Tereus and especially Cronus, who was Saturn in the Roman pantheon. The story of Tantalus also parallels this.

The wendigo is a creature appearing in the legends of the Algonquian people. It is thought of variously as a malevolent cannibalistic spirit that could possess humans or a monster that humans could physically transform into. Those who indulged in cannibalism were at particular risk,[29] and the legend appears to have reinforced this practice as taboo.

As used to demonize colonized or other groups

Unsubstantiated reports of cannibalism disproportionately relate cases of cannibalism among cultures that are already otherwise despised, feared, or are little known. In antiquity, Greek reports of cannibalism, (often called anthropophagy in this context) were related to distant non-Hellenic barbarians, or else relegated in Greek mythology to the 'primitive' chthonic world that preceded the coming of the Olympian gods: see the explicit rejection of human sacrifice in the cannibal feast prepared for the Olympians by Tantalus of his son Pelops. All South Sea Islanders were cannibals so far as their enemies were concerned. When the whaleship Essex was rammed and sunk by a whale in 1820, the captain opted to sail 3000 miles upwind to Chile rather than 1400 miles downwind to the Marquesas because he had heard the Marquesans were cannibals. Ironically many of the survivors of the shipwreck resorted to cannibalism to survive.

However, Herman Melville happily lived with the Marquesan Typees for a time after the other two tribes on the island told him they were cannibals. In his semi-autobiographical novel Typee, he reports seeing shrunken heads and having strong evidence that the tribal leaders ceremonially consumed the bodies of killed warriors of the neighboring tribe after a skirmish.

William Arens, author of The Man-Eating Myth: Anthropology and Anthropophagy,[30] questions the credibility of reports of cannibalism and argues that the description by one group of people of another people as cannibals is a consistent and demonstrable ideological and rhetorical device to establish perceived cultural superiority. Arens bases his thesis on a detailed analysis of numerous "classic" cases of cultural cannibalism cited by explorers, missionaries, and anthropologists. He asserted that many were steeped in racism, unsubstantiated, or based on second-hand or hearsay evidence.[31]

Arens' findings are controversial, and have been cited as an example of postcolonial revisionism.[32]

Conversely, Michel de Montaigne's essay "Of cannibals" introduced a new multicultural note in European civilization. Montaigne wrote that "one calls 'barbarism' whatever he is not accustomed to".[33]

Accounts


Among modern humans, cannibalism has been practiced by various groups.[34] In the past, it was practiced by humans in Europe,[35][36] South America,[37] among Iroquoian peoples in North America,[38] Maori in New Zealand,[39] the Solomon Islands,[40] parts of West Africa[12] and Central Africa,[12] some of the islands of Polynesia,[12] New Guinea,[41] Sumatra,[12] and Fiji.[42] Evidence of cannibalism has been found in ruins associated with the Anasazi culture of the Southwestern United States as well.[43][44]

Pre-history

Some anthropologists, such as Tim White, suggest that ritual cannibalism was common in human societies prior to the beginning of the Upper Paleolithic period. This theory is based on the large amount of "butchered human" bones found in Neanderthal and other Lower/Middle Paleolithic sites.[45] Cannibalism in the Lower and Middle Paleolithic may have occurred because of food shortages.[46] It has been also suggested that removing dead bodies through ritual cannibalism might been a means of predator control, aiming to eliminate predators' and scavengers' access to hominid (and early human) bodies.[47] Jim Corbett proposed that after major epidemics, when human corpses are easily accessible to predators, there are more cases of man-eating leopards,[48] so removing dead bodies through ritual cannibalism (before the cultural traditions of burying and burning bodies appeared in human history) might have had practical reasons for hominids and early humans to control predation.

In Gough's Cave, England, remains of human bones and skulls, around 15,000 years old, suggest that cannibalism took place amongst the people living in or visiting the cave,[49] and that they may have used human skulls as drinking vessels.[50][51]

According to one historical account, aboriginal tribes of Australia were "most certainly cannibals", and would willingly eat anyone who was killed in a fight; they would also eat men famed for their fighting ability who had died natural deaths "... out of pity and consideration for the body".[52]

Early history

Cannibalism is mentioned many times in early history and literature. It is reported in the Bible during the siege of Samaria (2 Kings 6:25–30). Two women made a pact to eat their children; after the first mother cooked her child the second mother ate it but refused to reciprocate by cooking her own child. A similar story is reported by Flavius Josephus during the siege of Jerusalem by Rome in 70 AD (see Mary of Bethezuba), and the population of Numantia during the Roman Siege of Numantia in the 2nd century BC was reduced to cannibalism and suicide.

As in modern times, though, reports of cannibalism were often told as apocryphal second and third-hand stories, with widely varying levels of accuracy. St. Jerome, in his letter Against Jovinianus, discusses how people come to their present condition as a result of their heritage, and then lists several examples of peoples and their customs. In the list, he mentions that he has heard that Atticoti eat human flesh and that Massagetae and Derbices (a people on the borders of India) kill and eat old people. [53] This points to the likelihood that St. Jerome's writing came from rumors and does not represent the situation accurately.[citation needed]

Researchers have found physical evidence of cannibalism in ancient times. In 2001, archaeologists at the University of Bristol found evidence of Iron Age cannibalism in Gloucestershire.[54] Cannibalism was practiced as recently as 2000 years ago in Great Britain.[55] In Germany, Emil Carthaus and Dr. Bruno Bernhard have observed 1,891 signs of cannibalism in the caves at the Hönne (1000 – 700 BC).[56]

Middle Ages

During the Muslim-Qurayš wars in the early 7th century, a case of cannibalism was reported. Following at the Battle of Uhud in 625, it is said that after killing Hamzah ibn Abdu l-Muṭṭalib, his liver was consumed by Hind bint 'Utbah (the wife of Abû Sufyan ibn Harb one of the commanders of the Qurayš army)[57] who later reportedly converted to Islam and became the mother of Muawiyah I founder of the Islamic Umayyad Caliphate.

Reports of cannibalism were also recorded during the First Crusade, as Crusaders were alleged to have fed on the bodies of their dead opponents following the Siege of Ma'arrat al-Numan. Amin Maalouf also alleges further cannibalism incidents on the march to Jerusalem, and to the efforts made to delete mention of these from western history.[58] During Europe's Great Famine of 1315–1317 there were many reports of cannibalism among the starving populations. In North Africa, as in Europe, there are references to cannibalism as a last resort in times of famine.[59]

The Moroccan Muslim explorer Ibn Batutta reported that one African king advised him that nearby people were cannibals (though this may have been a prank played on Ibn Batutta by the king to fluster his guest). However Batutta reported that Arabs and Christians were safe, as their flesh was "unripe" and would cause the eater to fall ill.

For a brief time in Europe, an unusual form of cannibalism occurred when thousands of Egyptian mummies preserved in bitumen were ground up and sold as medicine.[60] The practice developed into a wide-scale business which flourished until the late 16th century. This "fad" ended because the mummies were revealed actually to be recently killed slaves. Two centuries ago, mummies were still believed to have medicinal properties against bleeding, and were sold as pharmaceuticals in powdered form (see human mummy confection and mummia).[61]

In China during the Tang Dynasty, cannibalism was supposedly resorted to by rebel forces early in the period (who were said to raid neighboring areas for victims to eat), as well as both soldiers and civilians besieged during the rebellion of An Lushan. Eating an enemy's heart and liver was also claimed to be a feature of both official punishments and private vengeance.[62] References to cannibalizing the enemy has also been seen in poetry written in the Song Dynasty, (for example, in Man Jiang Hong) although the cannibalizing is perhaps poetic symbolism, expressing hatred towards the enemy.

While there is universal agreement that some Mesoamerican people practiced human sacrifice, there is a lack of scholarly consensus as to whether cannibalism in pre-Columbian America was widespread. At one extreme, anthropologist Marvin Harris, author of Cannibals and Kings, has suggested that the flesh of the victims was a part of an aristocratic diet as a reward, since the Aztec diet was lacking in proteins. While most pre-Columbian historians believe that there was ritual cannibalism related to human sacrifices, they do not support Harris's thesis that human flesh was ever a significant portion of the Aztec diet.[63][64][65] Others have hypothesized that cannibalism was part of a blood revenge in war.[66]

Early modern era

European explorers and colonizers brought home many stories of cannibalism practiced by the native peoples they encountered. The friar Diego de Landa reported about Yucatán instances,[67] and there have been similar reports by Purchas from Popayán, Colombia, and from the Marquesas Islands of Polynesia, where human flesh was called long pig.[68] According to Hans Egede, the Inuits, when they killed a woman accused of witchcraft, ate a portion of her heart.[69] It is recorded about the natives of the captaincy of Sergipe in Brazil: "They eat human flesh when they can get it, and if a woman miscarries devour the abortive immediately. If she goes her time out, she herself cuts the navel-string with a shell, which she boils along with the secondine, and eats them both."[70]

The 1913 Handbook of Indians of Canada (reprinting 1907 material from the Bureau of American Ethnology), claims that North American natives practicing cannibalism included "... the Montagnais, and some of the tribes of Maine; the Algonkin, Armouchiquois, Iroquois, and Micmac; farther west the Assiniboine, Cree, Foxes, Chippewa, Miami, Ottawa, Kickapoo, Illinois, Sioux, and Winnebago; in the South the people who built the mounds in Florida, and the Tonkawa, Attacapa, Karankawa, Caddo, and Comanche (?); in the Northwest and West, portions of the continent, the Thlingchadinneh and other Athapascan tribes, the Tlingit, Heiltsuk, Kwakiutl, Tsimshian, Nootka, Siksika, some of the Californian tribes, and the Ute. There is also a tradition of the practice among the Hopi, and mentions of the custom among other tribes of New Mexico and Arizona. The Mohawk, and the Attacapa, Tonkawa, and other Texas tribes were known to their neighbours as 'man-eaters.'"[71] The forms of cannibalism described included both resorting to human flesh during famines and ritual cannibalism, the latter usually consisting of eating a small portion of an enemy warrior.

As with most lurid tales of native cannibalism, these stories are treated with a great deal of scrutiny, as accusations of cannibalism were often used as justifications for the subjugation or destruction of "savages". However, there were several well-documented cultures that engaged in regular eating of the dead, such as New Zealand's Māori. In an 1809 incident known as the Boyd massacre, about 66 passengers and crew of the Boyd were killed and eaten by Māori on the Whangaroa peninsula, Northland. Cannibalism was already a regular practice in Māori wars.[72] In another instance, on July 11, 1821 warriors from the Ngapuhi tribe killed 2,000 enemies and remained on the battlefield "eating the vanquished until they were driven off by the smell of decaying bodies".[73] Māori warriors fighting the New Zealand government in Titokowaru's War in New Zealand's North Island in 1868–69 revived ancient rites of cannibalism as part of the radical Hauhau movement of the Pai Marire religion.[74]

Other islands in the Pacific were home to cultures that allowed cannibalism to some degree. In parts of Melanesia, cannibalism was still practiced in the early 20th century, for a variety of reasons — including retaliation, to insult an enemy people, or to absorb the dead person's qualities.[75] One tribal chief, Ratu Udre Udre in Rakiraki, Fiji, is said to have consumed 872 people and to have made a pile of stones to record his achievement.[76][77] The ferocity of the cannibal lifestyle deterred European sailors from going near Fijian waters, giving Fiji the name "Cannibal Isles". The dense population of Marquesas Islands, Polynesia, was concentrated in the narrow valleys, and consisted of warring tribes, who sometimes practiced cannibalism on their enemies. W. D. Rubinstein wrote:

It was considered a great triumph among the Marquesans to eat the body of a dead man. They treated their captives with great cruelty. They broke their legs to prevent them from attempting to escape before being eaten, but kept them alive so that they could brood over their impending fate. ... With this tribe, as with many others, the bodies of women were in great demand.[5]

This period of time was also rife with instances of explorers and seafarers resorting to cannibalism for survival. The survivors of the sinking of the French ship Méduse in 1816 resorted to cannibalism after four days adrift on a raft and their plight was made famous by Théodore Géricault's painting Raft of the Medusa. After the sinking of the Essex of Nantucket by a whale, on November 20, 1820, (an important source event for Herman Melville's Moby-Dick) the survivors, in three small boats, resorted, by common consent, to cannibalism in order for some to survive.[78] Sir John Franklin's lost polar expedition is another example of cannibalism out of desperation.[79] On land, the Donner Party found itself stranded by snow in a high mountain pass in California without adequate supplies during the Mexican-American War, leading to several instances of cannibalism.[80] Another notorious cannibal was mountain man Boone Helm, who was known as "The Kentucky Cannibal" for eating several of his fellow travelers, from 1850 until his eventual hanging in 1864.

The case of R v. Dudley and Stephens (1884) 14 QBD 273 (QB) is an English case which dealt with four crew members of an English yacht, the Mignonette, who were cast away in a storm some 1,600 miles (2,600 km) from the Cape of Good Hope. After several days, one of the crew, a seventeen-year-old cabin boy, fell unconscious due to a combination of the famine and drinking seawater. The others (one possibly objecting) decided then to kill him and eat him. They were picked up four days later. Two of the three survivors were found guilty of murder. A significant outcome of this case was that necessity was determined to be no defence against a charge of murder.

American consul James W. Davidson described in his 1903 book, The Island of Formosa, how the Chinese in Taiwan ate and traded in the flesh of Taiwanese aboriginals.[81]

Roger Casement, writing to a consular colleague in Lisbon on August 3, 1903 from Lake Mantumba in the Congo Free State, said: "The people round here are all cannibals. You never saw such a weird looking lot in your life. There are also dwarfs (called Batwas) in the forest who are even worse cannibals than the taller human environment. They eat man flesh raw! It's a fact." Casement then added how assailants would "bring down a dwarf on the way home, for the marital cooking pot ... The Dwarfs, as I say, dispense with cooking pots and eat and drink their human prey fresh cut on the battlefield while the blood is still warm and running. These are not fairy tales my dear Cowper but actual gruesome reality in the heart of this poor, benighted savage land."[82]

Modern era

World War II

Many instances of cannibalism by necessity were recorded during World War II. For example, during the 872-day Siege of Leningrad, reports of cannibalism began to appear in the winter of 1941–1942, after all birds, rats and pets were eaten by survivors. Leningrad police even formed a special division to combat cannibalism.[83][84] Following the Soviet victory at Stalingrad it was found that some German soldiers in the besieged city, cut off from supplies, resorted to cannibalism.[85]

Later, following the German surrender in January 1943, roughly 100,000 German soldiers were taken prisoner of war (POW). Almost all of them were sent to POW camps in Siberia or Central Asia where, due to being chronically underfed by their Soviet captors, many resorted to cannibalism. Fewer than 5,000 of the prisoners taken at Stalingrad survived captivity. The majority, however, died early in their imprisonment due to exposure or sickness brought on by conditions in the surrounded army before the surrender.[86]

The Australian War Crimes Section of the Tokyo tribunal, led by prosecutor William Webb (the future Judge-in-Chief), collected numerous written reports and testimonies that documented Japanese soldiers' acts of cannibalism among their own troops, on enemy dead, and on Allied prisoners of war in many parts of the Greater East Asia Co-Prosperity Sphere. In September 1942, Japanese daily rations on New Guinea consisted of 800 grams of rice and tinned meat. However, by December, this had fallen to 50 grams.[87]:78–80 According to historian Yuki Tanaka, "cannibalism was often a systematic activity conducted by whole squads and under the command of officers".[88]

In some cases, flesh was cut from living people. An Indian POW, Lance Naik Hatam Ali (later a citizen of Pakistan), testified that in New Guinea: "the Japanese started selecting prisoners and every day one prisoner was taken out and killed and eaten by the soldiers. I personally saw this happen and about 100 prisoners were eaten at this place by the Japanese. The remainder of us were taken to another spot 50 miles (80 kilometres) away where 10 prisoners died of sickness. At this place, the Japanese again started selecting prisoners to eat. Those selected were taken to a hut where their flesh was cut from their bodies while they were alive and they were thrown into a ditch where they later died."[89]

Another well-documented case occurred in Chichijima in February 1945, when Japanese soldiers killed and consumed five American airmen. This case was investigated in 1947 in a war crimes trial, and of 30 Japanese soldiers prosecuted, five (Maj. Matoba, Gen. Tachibana, Adm. Mori, Capt. Yoshii, and Dr. Teraki) were found guilty and hanged.[90] In his book Flyboys: A True Story of Courage, James Bradley details several instances of cannibalism of World War II Allied prisoners by their Japanese captors.[91] The author claims that this included not only ritual cannibalization of the livers of freshly killed prisoners, but also the cannibalization-for-sustenance of living prisoners over the course of several days, amputating limbs only as needed to keep the meat fresh.[92]

New Guinea

The Korowai tribe of south-eastern Papua could be one of the last surviving tribes in the world engaging in cannibalism.

Africa

During the 1892–1894 war between the Congo Free State and the Swahili-Arab city-states of Nyangwe and Kasongo in Eastern Congo, there were reports of widespread cannibalization of the bodies of defeated Arab combatants by the Batetela allies of Belgian commander Francis Dhanis.[93] The Batetela, "like most of their neighbors were inveterate cannibals."[94] According to Dhanis' medical officer, Captain Hinde, their town of Ngandu had "at least 2,000 polished human skulls" as a "solid white pavement in front" of its gates, with human skulls crowning every post of the stockade.[94]

In April 1892, 10,000 of the Batetela, under the command of Gongo Lutete, joined forces with Dhanis in a campaign against the Swahili-Arab leaders Sefu and Mohara.[94] After one early skirmish in the campaign, Hinde "noticed that the bodies of both the killed and wounded had vanished." When fighting broke out again, Hinde saw his Batetela allies drop human arms, legs and heads on the road.[95] One young Belgian officer wrote home: "Happily Gongo's men ate them up [in a few hours]. It's horrible but exceedingly useful and hygenic ... I should have been horrified at the idea in Europe! But it seems quite natural to me here. Don't show this letter to anyone indiscreet."[96] After the massacre at Nyangwe, Lutete "hid himself in his quarters, appalled by the sight of thousands of men smoking human hands and human chops on their camp fires, enough to feed his army for many days."[94]

In the 1980s, Médecins Sans Frontières, the international medical charity, supplied photographic and other documentary evidence of ritualized cannibal feasts among the participants in Liberia's internecine strife to representatives of Amnesty International who were on a fact-finding mission to the neighboring state of Guinea. However, Amnesty International declined to publicize this material; the Secretary-General of the organization, Pierre Sane, said at the time in an internal communication that "what they do with the bodies after human rights violations are committed is not part of our mandate or concern". The existence of cannibalism on a wide scale in Liberia was subsequently verified.[97]

The self-declared Emperor of the Central African Republic, Jean-Bédel Bokassa (Emperor Bokassa I), was tried on October 24, 1986 for several cases of cannibalism although he was never convicted.[98][99] Between April 17, and April 19, 1979 a number of elementary school students were arrested after they had protested against wearing the expensive, government-required school uniforms. Around 100 were killed.[100] Bokassa is said to have participated in the massacre, beating some of the children to death with his cane and allegedly ate some of his victims.[101]

Cannibalism has been reported in several recent African conflicts, including the Second Congo War, and the civil wars in Liberia and Sierra Leone. A UN human rights expert reported in July 2007 that sexual atrocities against Congolese women go "far beyond rape" and include sexual slavery, forced incest, and cannibalism.[102] This may be done in desperation, as during peacetime cannibalism is much less frequent;[103] at other times, it is consciously directed at certain groups believed to be relatively helpless, such as Congo Pygmies, even considered subhuman by some other Congolese.[104] It is also reported by some that witch doctors sometimes use the body parts of children in their medicine.[105] In the 1970s the Ugandan dictator Idi Amin was reputed to practice cannibalism.[106][107]

In Uganda, the Lord's Resistance Army have been accused of routinely engaging in ritual or magical cannibalism.[108]

North Korea

Reports of widespread cannibalism began to emerge from North Korea during the famine of the 1990s[109][110] and subsequent ongoing starvation. Kim Jong-il was reported to have ordered a crackdown in cannibalism in 1996.[111] Chinese travellers reported in 1998 that cannibalism had occured.[112][113] Three people in North Korea were reported to have been executed for selling or eating human flesh in 2006.[114] Further reports of cannibalism emerged in early 2013, including reports of a man executed for killing his two children for food.[115][116][117]

There are competing claims about how widespread cannibalism was in North Korea. Refugees reported that it was widespread[118] however Barbara Demick wrote in her 2010 book Nothing to Envy: Ordinary Lives in North Korea that it did not seem to be.[119]

Other cases

Further instances include cannibalism as ritual practice, and in times of drought, famine and other destitutions, as well as those being criminal acts and war crimes throughout the 20th century.

In West Africa, the Leopard Society was a secret society active into the mid-1900s and one that practiced cannibalism. Centred in Sierra Leone, Liberia and Côte d'Ivoire, the Leopard men would dress in leopard skins, waylaying travelers with sharp claw-like weapons in the form of leopards' claws and teeth.[120] The victims' flesh would be cut from their bodies and distributed to members of the society.[121]

As in some other Papuan societies, the Urapmin people engaged in cannibalism in war. Notably, the Urapmin also had a system of food taboo wherein dogs could not be eaten and had to be kept from breathing on food, unlike humans who could be eaten and with whom food could be shared.[122]

The Aghoris of northern India are a splinter sect of Hinduism who practice cannibalism in which they consume the flesh of the dead floated in the Ganges in pursuit of immortality and supernatural powers. Members of the Aghori drink from human skulls and practice cannibalism in the belief that eating human flesh confers spiritual and physical benefits, such as prevention of aging.[123][124][125]

During the 1930s, multiple acts of cannibalism were reported from Ukraine and Russia's Volga, South Siberian and Kuban regions during the Soviet famine of 1932–1933.[126]

Survival was a moral as well as a physical struggle. A woman doctor wrote to a friend in June 1933 that she had not yet become a cannibal, but was "not sure that I shall not be one by the time my letter reaches you." The good people died first. Those who refused to steal or to prostitute themselves died. Those who gave food to others died. Those who refused to eat corpses died. Those who refused to kill their fellow man died. ... At least 2,505 people were sentenced for cannibalism in the years 1932 and 1933 in Ukraine, though the actual number of cases was certainly much greater.[127]

Cannibalism was proven to have occurred in China during the Great Leap Forward, when rural China was hit hard by drought and famine.[128][129][130][131][132][133][134]

Prior to 1931, New York Times reporter William Buehler Seabrook, allegedly in the interests of research, obtained from a hospital intern at the Sorbonne a chunk of human meat from the body of a healthy human killed in an accident, then cooked and ate it. He reported, "It was like good, fully developed veal, not young, but not yet beef. It was very definitely like that, and it was not like any other meat I had ever tasted. It was so nearly like good, fully developed veal that I think no person with a palate of ordinary, normal sensitiveness could distinguish it from veal. It was mild, good meat with no other sharply defined or highly characteristic taste such as for instance, goat, high game, and pork have. The steak was slightly tougher than prime veal, a little stringy, but not too tough or stringy to be agreeably edible. The roast, from which I cut and ate a central slice, was tender, and in color, texture, smell as well as taste, strengthened my certainty that of all the meats we habitually know, veal is the one meat to which this meat is accurately comparable."[135][136]

In his book, The Gulag Archipelago, Soviet writer Aleksandr Solzhenitsyn described cases of cannibalism in 20th-century USSR. Of the famine in Povolzhie (1921–1922) he wrote: "That horrible famine was up to cannibalism, up to consuming children by their own parents — the famine, which Russia had never known even in Time of Troubles [in 1601–1603] ..."[137]

He said of the Siege of Leningrad (1941–1944): "Those who consumed human flesh, or dealt with the human liver trading from dissecting rooms ... were accounted as the political criminals ..."[138] And of the building of Northern Railway Prisoners Camp ("SevZhelDorLag") Solzhenitsyn reports, "An ordinary hard working political prisoner almost could not survive at that penal camp. In the camp SevZhelDorLag (chief: colonel Klyuchkin) in 1946–47 there were many cases of cannibalism: they cut human bodies, cooked and ate."[139]

The Soviet journalist Yevgenia Ginzburg was a former long-term political prisoner who spent time in the Soviet prisons, Gulag camps and settlements from 1938 to 1955. She described in her memoir, Harsh Route (or Steep Route), of a case which she was directly involved in during the late 1940s, after she had been moved to the prisoners' hospital.[140]

...The chief warder shows me the black smoked pot, filled with some food: 'I need your medical expertise regarding this meat.' I look into the pot, and hardly hold vomiting. The fibres of that meat are very small, and don't resemble me anything I have seen before. The skin on some pieces bristles with black hair (...) A former smith from Poltava, Kulesh worked together with Centurashvili. At this time, Centurashvili was only one month away from being discharged from the camp (...) And suddenly he surprisingly disappeared. The wardens looked around the hills, stated Kulesh's evidence, that last time Kulesh had seen his workmate near the fireplace, Kulesh went out to work and Centurashvili left to warm himself more; but when Kulesh returned to the fireplace, Centurashvili had vanished; who knows, maybe he got frozen somewhere in snow, he was a weak guy (...) The wardens searched for two more days, and then assumed that it was an escape case, though they wondered why, since his imprisonment period was almost over (...) The crime was there. Approaching the fireplace, Kulesh killed Centurashvili with an axe, burned his clothes, then dismembered him and hid the pieces in snow, in different places, putting specific marks on each burial place. ... Just yesterday, one body part was found under two crossed logs.

When Uruguayan Air Force Flight 571 crashed into the Andes on October 13, 1972, the survivors resorted to eating the deceased during their 72 days in the mountains. Their story was later recounted in the books Alive: The Story of the Andes Survivors and Miracle in the Andes as well as the film Alive, by Frank Marshall, and the documentaries Alive: 20 Years Later (1993) and Stranded: I've Come from a Plane that Crashed in the Mountains (2008).

Cannibalism was reported by the journalist Neil Davis during the South East Asian wars of the 1960s and 1970s. Davis reported that Cambodian troops ritually ate portions of the slain enemy, typically the liver. However he, and many refugees, also report that cannibalism was practiced non-ritually when there was no food to be found. This usually occurred when towns and villages were under Khmer Rouge control, and food was strictly rationed, leading to widespread starvation. Any civilian caught participating in cannibalism would have been immediately executed.

On July 23, 1988, Rick Gibson ate the flesh of another person in public. Because England does not have a specific law against cannibalism, he legally ate a canapé of donated human tonsils in Walthamstow High Street, London.[141][142] A year later, on April 15, 1989, he publicly ate a slice of human testicle in Lewisham High Street, London.[143][144] When he tried to eat another slice of human testicle at the Pitt International Galleries in Vancouver on July 14, 1989, the Vancouver police confiscated the testicle hors d'œuvre.[145] However, the charge of publicly exhibiting a disgusting object was dropped and he finally ate the piece of human testicle on the steps of the Vancouver court house on September 22, 1989.[146]

Santa Ana winds

       Here's the wiki link of the subject:  http://en.wikipedia.org/wiki/Santa_Ana_winds

            I myself lived in a Southern California area subject to these winds. Mostly it made my house "dusty", or so my mother told me. As a very young teenage boy, I really did not care at the time.

            I have also lived in areas subject to Siberian winds over the Gobi Desert. Even the Yellow  Sea got its name from this weather effect, or so the story goes.

Induction cooking 

From Wikipedia, the free encyclopedia

Induction cooking uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove. For nearly all models of induction cooktop, a cooking vessel must be made of a ferromagnetic metal, or placed on an interface disk which enables non-induction cookware to be used on induction cooking surfaces.

In an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food. While the current is large, it is produced by a low voltage.

An induction cooker is faster and more energy-efficient than a traditional electric cooking surface. It allows instant control of cooking energy similar to gas burners. Other cooking methods use flames or red-hot heating elements; induction heating heats only the pot. Because the surface of the cook top is heated only by contact with the vessel, the possibility of burn injury is significantly less than with other methods. The induction effect does not directly heat the air around the vessel, resulting in further energy efficiencies. Cooling air is blown through the electronics but emerges only a little warmer than ambient temperature.

The magnetic properties of a steel vessel concentrate the induced current in a thin layer near its surface, which makes the heating effect stronger. In non-magnetic materials like aluminum, the magnetic field penetrates too far, and the induced current encounters little resistance in the metal.[1] At least one high-frequency "all metal" cooker is available, that works with lower efficiency on non-magnetic metal cookware.

Design

An induction cooker transfers electrical energy by induction from a coil of wire into a metal vessel that must be ferromagnetic. The coil is mounted under the cooking surface, and a large alternating current is passed through it. The current creates a changing magnetic field. When an electrically conductive pot is brought close to the cooking surface, the magnetic field induces an electrical current, called an "eddy current", in the pot. The eddy current, flowing through the electrical resistance, produces heat; the pot gets hot and heats its contents by heat conduction.

The cooking vessel is made of stainless steel or iron. The increased magnetic permeability of the material decreases the skin depth, concentrating the current near the surface of the metal, and so the electrical resistance will be further increased. Some energy will be dissipated wastefully by the current flowing through the resistance of the coil. To reduce the skin effect and consequent heat generation in the coil, it is made from litz wire, which is a bundle of many smaller insulated wires in parallel. The coil has many turns, while the bottom of the pot effectively forms a single shorted turn. This forms a transformer that steps down the voltage and steps up the current. The resistance of the pot, as viewed from the primary coil, appears larger. In turn, most of the energy becomes heat in the high-resistance steel, while the driving coil stays cool.

The cooking surface is made of a glass-ceramic material which is a poor heat conductor, so only a little heat is lost through the bottom of the pot. In normal operation the cooking surface stays cool enough to touch without injury after the cooking vessel is removed.

Units may have one, two, three, four or five induction zones, but four (normally in a 30-inch-wide unit) is the most common in the US and Europe. Two coils are most common in Hong Kong and three are most common in Japan. Some have touch-sensitive controls. Some induction stoves have a memory setting, one per element, to control the time that heat is applied. At least one manufacturer makes a "zoneless" induction cooking surface with multiple induction coils. This allows up to five utensils to be used at once anywhere on the cooking surface, not just on pre-defined zones.[2]

Small stand-alone portable induction cookers are relatively inexpensive, priced from around US$20 in some markets.

Cookware

Cookware for an induction cooking surface will be generally the same as used on other stoves. Some cookware or packaging is marked with symbols to indicate compatibility with induction, gas, or electric heat. Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans will work on an induction cooking surface. Stainless steel pans will work on an induction cooking surface if the base of the pan is a magnetic grade of stainless steel. If a magnet sticks well to the sole of the pan, it will work on an induction cooking surface. An "all-metal" cooker will work with non-ferrous cookware, but available models are limited.

For frying, a pan with a base that is a good heat conductor is needed to spread the heat quickly and evenly. The sole of the pan will be either a steel plate pressed into the aluminum, or a layer of stainless steel over the aluminum. The high thermal conductivity of aluminum pans makes the temperature more uniform across the pan. Stainless frying pans with an aluminum base will not have the same temperature at their sides as an aluminum sided pan will have. Cast iron frying pans work well with induction cooking surfaces but the material is not as good a thermal conductor as aluminum.

When boiling water, the circulating water spreads the heat and prevents hot spots. For products such as sauces, it is important that at least the base of the pan incorporates a good heat conducting material to spread the heat evenly. For delicate products such as thick sauces, a pan with aluminum throughout is better, since the heat flows up the sides through the aluminum, allowing the cook to heat the sauce rapidly but evenly[citation needed].

Aluminum or copper alone does not work on an induction stove because of the materials’ magnetic and electrical properties.[3] Aluminum or copper cookware is more conductive than steel, and the skin depth in these materials is larger since they are non-magnetic. The current flows in a thicker layer in the metal, encounters less resistance and so produces less heat. The induction cooker will not work efficiently with such pots.

The heat that can be produced in a pot is a function of the surface resistance. A higher surface resistance produces more heat for similar currents. This is a “figure of merit” that can be used to rank the suitability of a material for induction heating. The surface resistance in a thick metal conductor is proportional to the resistivity divided by the skin depth. Where the thickness is less than the skin depth, the actual thickness can be used to calculate surface resistance.[3] Some common materials are listed in this table.

To get the same surface resistance as with carbon steel would require the metal to be thinner than is practical for a cooking vessel; a copper vessel bottom would be 1/56th the thickness of the carbon steel pot. Since the skin depth is inversely proportional to the square root of the frequency, this suggests that much higher frequencies (say, several megahertz) would be required to obtain equivalent heating in a copper pot as in an iron pot at 24 kHz. Such high frequencies are not feasible with inexpensive power semiconductors; in 1973 the silicon-controlled rectifiers used were limited to no more than 40 kHz.[3] Even a thin layer of copper on the bottom of a steel cooking vessel will shield the steel from the magnetic field and make it unusable for an induction top.[3] Some additional heat is created by hysteresis losses in the pot due to its ferromagnetic nature, but this creates less than ten percent of the total heat generated.[4]

"All metal" models

New types of power semiconductors and low-loss coil designs have made an all-metal cooker possible, but the electronic components are relatively bulky.

Panasonic Corporation in 2009 developed a consumer induction cooker that uses a higher-frequency magnetic field, and a different oscillator circuit design, to allow use with non-ferrous metals.[5][6]

History

An early induction cooker patent from 1909 illustrates the principle. The coil of wire S induces a magnetic field in the magnetic core M. The magnetic field passes through the bottom of the pot A, inducing eddy currents within it. Unlike this concept, a modern cooking surface uses electronically-generated high-frequency current

First patents date from the early 1900s.[7] Demonstration stoves were shown by the Frigidaire division of General Motors in the mid-1950s[8] on a touring GM showcase in North America. The induction cooker was shown heating a pot of water with a newspaper placed between the stove and the pot, to demonstrate the convenience and safety. This unit, however, was never put into production.

Modern implementation in the USA dates from the early 1970s, with work done at the Research & Development Center of Westinghouse Electric Corporation at Churchill Borough, near Pittsburgh,[3] That work was first put on public display at the 1971 National Association of Home Builders convention in Houston, Texas, as part of the Westinghouse Consumer Products Division display.[citation needed] The stand-alone single-burner range was named the Cool Top Induction Range. It used paralleled Delco Electronics transistors developed for automotive electronic ignition systems to drive the 25 kHz current.

Westinghouse decided to make a few hundred production units to develop the market. Those were named Cool Top 2 (CT2) Induction ranges. The development work was done at the same R&D location, by a team led by Bill Moreland and Terry Malarkey. The ranges were priced at $1,500, including a set of high quality cookware made of Quadraply, a laminate of stainless steel, carbon steel, aluminum and another layer of stainless steel (outside to inside).

Production took place in 1973 through to 1975 and stopped, coincidentally, with the sale of Westinghouse Consumer Products Division to White Consolidated Industries Inc.

CT2 had four burners of about 1,600 watts each. The range top was a Pyroceram ceramic sheet surrounded by a stainless-steel bezel, upon which four magnetic sliders adjusted four corresponding potentiometers set below. That design, using no through-holes, made the range proof against spills. The electronic section was made in four identical modules cooled by fans.

In each of the electronics modules, the 240V, 60 Hz domestic line power was converted to between 20V to 200V of continuously variable DC by a phase-controlled rectifier. That DC power was in turn converted to 27 kHz 30 A (peak) AC by two arrays of six paralleled Motorola automotive-ignition transistors in a half-bridge configuration driving a series-resonant LC oscillator, of which the inductor component was the induction-heating coil and its load, the cooking pan. The circuit design, largely by Ray Mackenzie,[9] successfully dealt with certain bothersome overload problems.

Control electronics included functions such as protection against over-heated cook-pans and overloads. Provision was made to reduce radiated electrical and magnetic fields.[10][11] There was also magnetic pan detection.[12]

CT2 was UL Listed and received Federal Communications Commission (FCC) approval, both firsts. Numerous patents were also issued. CT2 won several awards, including Industrial Research Magazine's IR-100 1972 best-product award [13] and a citation from the United States Steel Association. Raymond Baxter demonstrated the CT2 on the BBC series Tomorrow's World. He showed how the CT2 could cook through a slab of ice.

Sears Kenmore sold a free-standing oven/stove with four induction-cooking surfaces in the mid-1980s (Model Number 103.9647910). The unit also featured a self-cleaning oven, solid-state kitchen timer and capacitive-touch control buttons (advanced for its time). The units were more expensive than standard cooking surfaces.

In 2009 Panasonic developed an all-metal induction cooker that used a different coil design and a higher operating frequency to allow operation with non-ferrous metal cookware. However, the units operate with somewhat reduced coupling efficiency and so have reduced power compared to operation with ferrous cookware.

Use

Induction equipment may be a built-in surface, part of a range, or a standalone surface unit. Built-in and rangetop units typically have multiple elements, the equivalent of separate burners on a gas-fueled range. Stand-alone induction modules are usually single-element, or sometimes have dual elements. All such elements share a basic design: an electromagnet sealed beneath a heat-resisting glass-ceramic sheet that is easily cleaned. The pot is placed on the ceramic glass surface and begins to heat up, along with its contents.

In Japan, some models of rice cookers are powered by induction. In Hong Kong, power companies list a number of models.[14] Asian manufacturers have taken the lead in producing inexpensive single-induction-zone surfaces; efficient, low-waste-heat units are advantageous in densely populated cities with little living space per family, as many Asian cities are. Induction cookers are less frequently used in other parts of the world.

Induction ranges may be applicable in commercial restaurant kitchens. Electric cooking avoids the cost of natural gas piping and in some jurisdictions may allow simpler ventilation and fire suppression equipment to be installed.[15] Drawbacks for commercial use include possible breakages of the glass cook-top, higher initial cost and the requirement for magnetic cookware.

Benefits

This form of flameless cooking has certain advantages over conventional gas flame and electric cookers, as it provides rapid heating, improved thermal efficiency, and greater heat consistency, yet with precise control similar to gas.[16] In situations in which a hotplate would typically be dangerous or illegal, an induction plate is ideal, as it creates no heat itself.

The high efficiency of power transfer into the cooking vessel makes heating food faster on an induction cooking surface than on other electric cooking surfaces. Because of the high efficiency, an induction element has heating performance comparable to a typical consumer-type gas element, even though the gas burner would have a much higher power input.[17]

Induction cookers are safer to use than conventional cookers because there are no open flames. The surface below the cooking vessel is no hotter than the vessel; only the pan generates heat. The control system shuts down the element if a pot is not present or not large enough. Induction cookers are easy to clean because the cooking surface is flat and smooth, even though it may have several heating zones. Since the cooking surface is not directly heated, spilled food does not burn on the surface.

Since heat is being generated by an induced electric current, the unit can detect whether cookware is present (or whether its contents have boiled dry) by monitoring how much power is being absorbed. That allows functions such as keeping a pot at minimal boil or automatically turning an element off when cookware is removed.

Because the cook top is shallow compared to a gas-fired or electrical coil cooking surface, wheelchair access can be improved; the user's legs can be below the counter height and the user's arms can reach over the top.[16]

Limitations

Cookware must be compatible with induction heating; glass and ceramics are unusable, as are solid copper or solid aluminum cookware for most models of cooker. Cookware must have a flat bottom since the magnetic field drops rapidly with distance from the surface. (Special and costly wok-shaped units are available for use with round-bottom woks.) Induction disks are metal plates--much like a skillet with no sides--that heat up non-ferrous pots by contact, but these sacrifice much of the power and efficiency of direct use of induction in a compatible cooking vessel.

Manufacturers advise consumers that the glass ceramic top can be damaged by impact, although cooking surfaces are required to meet minimal product safety standards for impact.[18] Aluminum foil can melt onto the top and cause permanent damage or cracking of the top. Damage by impact also relates to sliding pans across the cooking surface, which users are advised against. As with other electric ceramic cooking surfaces there may be a maximum pan size allowed by the manufacturer.

A small amount of noise is generated by an internal cooling fan. Audible noise (a hum or buzz) may be produced by cookware exposed to high magnetic fields, especially at high power if the cookware has loose parts; better-grade cookware, with welded-in cladding layers and solid rivetting, should not manifest such noises. Some users may detect a whistle or whine sound from the cookware, or from the power electronic devices. Some cooking techniques available when cooking over a flame are not applicable. Persons with implanted cardiac pacemakers or other electronic medical implants may be advised by their doctors to avoid proximity to induction cooking surfaces and other sources of magnetic fields.[16] Radio receivers near the unit may pick up some electromagnetic interference.

An induction (or any electric) stove will not operate during a power outage. Older gas-stoves do not need electric power to operate; however, modern gas-stoves with electrical ignition require an external ignition source (e.g. matches) during power outages.

Efficiency and environmental impact

According to the U.S. Department of Energy, the efficiency of energy transfer for an induction cooker is 84%, versus 74% for a smooth-top non-induction electrical unit, for an approximate 12% saving in energy for the same amount of heat transfer.[19]

Energy efficiency is the ratio between energy delivered to the food and that consumed by the cooker, considered from the "customer side" of the energy meter. Cooking with gas has an energy efficiency of about 40% at the customer's meter and can be raised only by using very special pots,[20] so the DOE efficiency value will be used.

When comparing consumption of energies of different kinds, in this case natural gas and electricity, the method used by the US Environmental Protection Agency refers to source (also called primary) energies. They are the energies of the raw fuels that are consumed to produce the energies delivered on site.[21] The conversion to source energies is done by multiplying site energies by appropriate source-site ratios. Unless there are good reasons to use custom source-site ratios (for example for non US residents or on-site solar), EPA states that "it is most equitable to employ national-level ratios".[22] These ratios amount to 3.34 for electricity purchased from the grid, 1.0 for on-site solar, and 1.047 for natural gas. The natural gas figure is slightly greater than 1 and mainly accounts for distribution losses. The energy efficiencies for cooking given above (84% for induction and 40% for gas) are in terms of site energies at the customer's meters. The (US averaged) efficiencies recalculated relative to source fuels energies are hence 25% for induction cooking surfaces using grid electricity, 84% for induction cooking surfaces using on-Site Solar, and 38% for gas burners.

Source-site ratios are not formalized yet in Western Europe. A common consensus should arise on unified European ratios in view of the extension of the Energy Label to domestic water heaters. Unofficial figures for European source-site ratios are about 2.2 for electricity, 1.0 for on-site solar, and 1.02 for natural gas, thus giving overall (referred to source energy) efficiencies of 38% and 84% for induction cooking surfaces (depending on source electricity) and 39% for gas burners.

These provisional figures need to be somehow adjusted due to the higher gas burner efficiency, allowed in Europe by a less stringent limit on carbon monoxide emission at the burner. European and US standards differ in test conditions. The US ANSI Z21.1 standard allows a lower concentration of carbon monoxide (0.08%), compared to the European standard EN 30-1-1 which allows 0.2%.[23][24] The minimum gas burner efficiency required in the EU by EN 30-2-1 is 52%,[24] higher than the average 40% efficiency measured in US by DOE. The difference is mainly due to the weaker CO emission limit in EU, that allows more efficient burners, but also due to different ways in which the efficiency measurements are performed.

Whenever local electricity emits less than 435 grams of CO2 per kWh, the greenhouse effect of an induction cooker will be lower than that of a gas cooker. This again comes from the relative efficiencies (84% and 40%) of the two surfaces and from the standard 200 (±5) grams CO2/kWh emission factor for combustion of natural gas at its net (low) calorific value.[improper synthesis?]

Gas cooking efficiencies may be lower if waste heat generation is taken into account. Especially in restaurants, gas cooking can significantly increase the ambient temperature in localized areas. Not only may extra cooling be required but zoned venting may be needed to adequately condition hot areas without overcooling other areas. Costs must be considered on an individual situation due to numerous variables in temperature differences, facility layout or openness, and heat generation schedule. Induction cooking using grid electricity may surpass gas efficiencies when waste heat and air comfort are quantified.

The market for induction stoves is dominated by German manufacturers, such as AEG, Bosch, Fissler, Miele and Siemens. The Spanish company Fagor, Italian firm Smeg and Sweden's Electrolux are also key players in the European market. Prices range from about GB£250 to 1,000 within the United Kingdom. In 2006, Stoves launched the UK's first domestic induction range cooker at a slightly lower cost than those imported.

The European induction cooking market for hotels, restaurants and other caterers is primarily satisfied by smaller specialist commercial induction catering equipment manufacturers such as Adventys of France, Control Induction and Target Catering Equipment of the UK and Scholl of Germany.

Taiwanese and Japanese electronics companies are the dominant players in induction cooking for East Asia. After aggressive promotions by utilities in HK like Power HK Ltd, many local brands like UNIVERSAL, icMagIC, Zanussi, iLighting, German Pool also emerged. Their power and ratings are high, more than 2,800 watts. They are multiple zone and capable of performing better than their gas counterpart. The efficiency is as high as 90% and saves a lot of energy and is environmentally friendly. Their use by local Chinese for wok cooking is becoming popular. Some of these companies have also started marketing in the West. However, the product range sold in Western markets is a subset of that in their domestic market; some Japanese electronics manufacturers only sell domestically.

In the United States, as of early 2013 there are over five dozen brands of induction-cooking equipment available, including both build-in and countertop residential equipment and commercial-grade equipment. Even restricting to build-in residential-use units, there are over two dozen brands being sold; residential countertop units add another two-dozen-plus brands to the count.

The National Association of Home Builders in 2012 estimated that, in the United States, induction cooktops held only 4% of sales, compared to gas and other electric cooktops.[25]

In April of 2010, The New York Times reported that "In an independent survey last summer by the market research company Mintel of 2,000 Internet users who own appliances, only 5 percent of respondents said they had an induction range or cooktop. . . . Still, 22 percent of the people Mintel surveyed in connection to their study last summer said their next range or cooktop would be induction."[26]
