> While microbes fed on carbon dioxide, hydrogen and oxygen to produce edible protein may raise more than a few eyebrows among skeptical consumers,
carbon dixide and oxigen are cheap. Hydrogen is expensive. These kind of post always hide the cost.
Also, to "produce edible protein" you need nitrogen atoms that are not in carbon dioxide, hydrogen and oxygen. If you use nitrogen from the air that is cheap, the conversion is difficult and expensive. If you use another source like nitrates, amonia or urea, they are expensive.
