"Precision Fermentation" will bankrupt beef and livestock and chicken farmers within 5 years. And it's a good thing!

[QUOTE="eclipsenow, post: 77398154, member: 274355"] Sure - and it feeds more people on vastly less land than cattle. But Precision Fermentation feeds more people on [I]vastly [/I]less land than soy protein! Why? Because the energy to grow these bugs comes from solar panels which are already more efficient than photosynthesis. Plants take about 6% of the sunlight, and only deliver a minute fraction of that back as protein and fats. It's an even worse return if we feed those plants to chickens, let alone cattle. But solar panels harvest around 15-20% of the sunlight today, split water, and then give 70% of that energy directly to the bacteria to eat in the form of hydrogen. So that's like 10.5%-14% pf the sunlight as hydrogen going straight to the bugs. Now here's the awesome bit. The potential for renewable power is huge. Wind has huge potential, especially as it works at night to help solar along. Solar could supply us with 12 times the electricity we currently use if we covered all our rooftops and fresh water reservoirs. And that's without touching any land yet!
