There's also a startup that claims you can turn fossil fuels directly into butter and use less fossil fuels than you would going through the traditional process of farming.
The first part we know is true, the Germans in WW2 fed some troops up to 800 calories a day of coal butter, which was black margarine synthesized from coal.
Using less than needed for fertilizer for farming though seems unlikely, coal butter was born from desperation for immediate calorie source, not because it was cheaper or more efficient.
