> The company first uses electricity to split water and obtain hydrogen, which is then mixed with carbon dioxide and fertilizers such as phosphorus and ammonia. These are then fed to an undisclosed type of soil-derived bacteria, and through a fermentation process, Solar Foods ends up with a powder made of 50% protein, 25% carbohydrates, 10% fat, and 15% other nutrients.
I think it is important to know what sort of Protein, Carbs, Fat and Nutrients.
But looking at those numbers, are we going to see people in the future living on Soylent that is 10x cheaper than its price today?
I assume the left out the part where they take Nitrogen from the air as part of the fermentation process.
Plants also produce food from CO2 + Water + solar energy. How does it compare to plants?
that creates these proteins/food.
So it is not actually "out of thin air", and until we don't know how much Nutrients & Vitamins are used (and of course how much electricity and water) we have no way to know how "efficient" the process is.
I mean, for all we know, it could be needed (intentionally exaggerated) 1 M3 of water, 10 KWh, 15 Kg of Nutrients and Vitamins besides 1 Kg of CO2 to get 1 Kg of food.
Google lead me to a previous discussion on HN . Apparently the distinction is that this doesn't require carbohydrate feedstock , i.e. no dependence on conventional agriculture. Which is big if true.
> In its dry powered format, Vainikka compared Solein’s nutritional profile to that of soy, algae, or some animal-based proteins. It contains 50% protein with all the essential amino acids, 5-10% fat, 20-25% carbohydrates, as well as Vitamin B.
I am more concerned about the health implication of such foods. I don't think it's enough to say an artificially produced food does not contain any harmful substances. The specific ratios of micronutrients and amino acids and such have unknown impacts on our health, so, this is as scary as it is exciting.
Presumably their revolutionary process is Yet Another Yeast.
Also, how do they account for the need for trace elements that I assume even a single celled organism would need. For example, where does it get selenium and sulfur?
