Nothing odd about flagrant hypocrisy, it's part of the brand

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.)

How would this work?

It would be one of their main talking points if the majority of farmers were black/latino.

Breathless tech reporters have discovered farming

The headline is a reference to the phrase ‘bread from air’, which was used to describe the applications of the Haber process.

Which is in turn doubtless a “mana from heaven” reference from abrahamic religious mythology

Carbon 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.

the majority of farm workers are Latino in many parts of Texas and California. problem is the ones doing the political lobbying are big time corporate farm owners who are almost all rich white and conservative.

This will claim some % of marketshare for cost reasons alone.

Also there's various startups working on casein (milk proteins) produced by bacteria, fungi or even algea. Some solution of sugars + nutrients in, casein rich product out. That in turn useable for many (all?) things animal milk is used for today: cheese, yogurt, quark, skyr, kefir, ice cream etc. Potentially a drop-in replacement for any of those.

Some of this would already be on the market, if obtaining regulatory approval wasn't so extremely difficult & time-consuming (partly for good reasons).

Earlier quoted context omitted.

Coal margarine, this protein powder and some vitamins, I wonder how long human could survive on such "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. https://en.wikipedia.org/wiki/Fischer%E2%80%93Tropsch_proces...

I 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.
