During WW2 Germany was making edible fats/margarine out of coal. Similarly, the atmospheric CO2 can be a source of carbon, especially say on Mars.
(another thing back then in Germany - ramjet engine using coal in a metal basket as a fuel. The war does put minds to work - radars/computers/nukes on the Allies side also come to mind.)
Coal margarine, this protein powder and some vitamins, I wonder how long human could survive on such "diet".
Our cats and dogs live on such a diet (until you learn what the supermarket cat/dogfood really is and take them off it). Vets have been saying about all those health problems resulting from that diet.
60kg of coal per 1kg of butter. You need about 3kg of meal for 1kg of chicken. 1.7kf of feed per 1kg of edible crickets.

I just think it's pretty amazing.
