I only have common sense. of course the whole thing is less water intensive then having to nurture an animal for 2 years and then kill it. but you can’t compare industrial waste water and water usage on a farm.
well, renewable energy… you could say the same for a farm. just put solar on the roof, like they do anyway. yes, you need less diesel for a factory product. but you still need an agricultural product, you don’t grow the stuff out of thin air. so diesel will be the same.
then you will need lots more of energy. you need technology. you need chemicals. and so on. you need specialist, chemists, industrial mechanics. all that costs a whole lot of ressources, and ratches up co2 footprint as well.
its like the idea of insect protein.
i dont think this will realize into reality at all, in a meaningfull scale, i mean. the whole thing is just a technical nightmare.
its like urban farms with indoor lights and hydroponics. its just not efficient.
