In 2011 Japanese Professor Mitsuyuki Ikeda proposed a synthetic burger made from sewage mud (aka human excrement), soya, and steak sauce with artificial coloring. This would cut down on waste and also help the environment with animal methane emissions. It would be a endless supply of food for poor nations. But when further investigation revealed that the sources were suspicious, the Turd Burger was seen more as either a hoax or unfunded private experiment. For the record, the Nazis made synthetic food in 1945 for October 1945 issue. It consisted of vita gels, woven synthetic meat strands, and a canister pump synthetic potato mash. All carried in one unit. US Army captured it and tried their own versions in the 1950s. Never replaced C-RATs. Was forgotten. A true synthetic burger was made in 2013. I owe this one to Patrick whose Soylent Green parody made me remember this odd topic.
