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.)

- trhway 4mo agoOur 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.

- thinkcontext 4mo agoI believe that they made the "butter" out of the leftovers (paraffin) from making liquid fuel out of the coal. So, its not a straight 60:1 ratio, you'd need to add some more products to the equation.

- vixen99 4mo agoCarbon fixing takes place via photosynthesis plus the light independent Calvin cycle. Hence the extensive greening that's taken place since CO2 elevation. This was first noticed via satellite in early 1980s. Overall there has been an increase of around 25-50% of vegetated land area. Productivity gains have been around 10%. Elevated CO2 has been the main driver. Plants got to get their (45-50% of their mass) carbon from somewhere.
