Finnish company makes food from thin air - Big Think
https://bigthink.com/technology-innovation/protein-from-air
Solar Foods makes Solein by extracting CO₂ from air using carbon-capture technology, and then combines it with water, nutrients and vitamins, using 100 percent renewable solar energy from partner Fortum to promote a natural fermentation process similar to the one that produces yeast and lactic acid bacteria.
When the company claims its single-celled protein is "free from agricultural limitations," they're not kidding. Being produced indoors means Solar Foods is not dependent on arable land, water (i.e., rain), or favorable weather.
The company is already working with the European Space Agency to develop foods for off-planet production and consumption. (The idea for Solein actually began at NASA.) They also see potential in bringing protein production to areas whose climate or ground conditions make conventional agriculture impossible.
And let's not forget all those beef-free burgers based on pea and soy proteins currently gaining popularity. The environmental challenge of scaling up the supply of those plants to meet their high demand may provide an opening for the completely renewable Solein — the company could provide companies that produce animal-free "meats," such as Beyond Meat and Impossible Foods, a way to further reduce their environmental impact.
