Look at that diagram very carefully. Sure doesn’t look very efficient. Odd that they are using sunshine to power their operation. Let’s ramp that operation up to support a million people. Looks similar to the cold fusion just around the corner with no economic analysis.
There has been a number of companies who have used microbial life to make food be it protein or starches or lipids. The Soviets used naptha to grow microbial proteins for animal feed on a scale of millions of kg per year. The British used natural gas to do the same thing during the 1970s and 80s using methogenic bacteria. UT Austin GMO a cyanobacteria to grow and excrete glucose directly from it’s cellular membranes while growing in salt water. Glucose is the base molecule for all cellular respiration including humans it is what is in IV fluids given people who cannot eat you can live on glucose , protein and lipids given via IV fluids btw. UT then designed a Ecoli to take electricity and also excrete pure glucose using the hydrogen proton path way off one side of a electrolysis cell with CO2 dissolved like a soda in the water. They succeeded in turning salt water.CO2 and electricity into the base food for every life form on earth that is aerobic that means every mammal, every avian, and all other vertebrates like fish and reptiles. Every one of them has at the base of it’s biological imperative the need for 6 carbon glucose. Everything any of them eats is turned into glucose ultimately by the digestive process and used for cellular respiration. Humans have the technology to leap well above what nature has in efficiency by a factor of 20 or more. Our livestock could care less if they eat single cell protein or not. Same for carbohydrates they could care less if its glucose or sucrose or starches from GMO tanks or sugar cane fields or corn fields once in pelleted feed form they could care less.
