>Seriously. Solein® is a unique single-cell protein made with a fully natural fermentation process. Using just air and electricity as its primary raw materials, Solein is the most sustainable protein in the world.

so..... instead of "wasting" time in spending water and soil and fertilizer into making plants that use solar energy to create "food", we skip that step and just use electricity that is generated from solar energy and make protein out of it..... law of thermodynamics say matter can neither be created nor destroyed so unless this is reducing inefficiencies of the existing plant model, isnt it 1 unit of electricty=1 unit of protein?

or are they aiming for heatpump style efficiencies? 5:1??

‘Sustainable’ in the food context is much more around total resource use (land, water, materials), waste products (ghgs and waste water) rather than a primary focus of energy efficiency.

Besides - heatpumps are largely the exception in thermodynamics, expecting anything more than 100% efficiency for most non-heat moving applications should not be expected.
