News Making protein out of CO2 and electricity

[Retu]

Technical Research Centre of Finland and Lappeenranta University of Technology have developed technology to produce edible protein out of CO2 and electricity. The researchers estimate the process could be as 10 times as energy efficient as photosynthesis.

The process is still in its early stages, so the yield is low: 1 gram of protein takes about two weeks to produce in laboratory. The next step is pilot production, where they will try to increase the yield to such quantities that commercialization is possible. It will be interesting to see if the technology could offer a solution to world's hunger problem.

"Single-celled protein"? What's that when it's at home? I suspect they're using a microbe, fungus, or similar and that additional nutrients would be required to provide the nitrogen and hydrogen as well as sustaining the organisms that provide the service of their ribosomes. What does the output look like - I expect it's a paste at best. Proteins are also more than carbon and oxygen. The article is either badly written or badly translated - perhaps both.

Well--you have both CO2 and electricity at power plants--and what you do is re-introduce buried biomass back to the surface....
I seem to remember folks wanting to turn oil into food in the 1970's.
