create synthesized food calories...without corn: But, yay, for shelf-stable (prepper?) puddings, gravies, personal powder-like product, and a dry long-hair dog grooming detangler (that's how I use corn starch)...

FOOD PRODUCTION
New method makes starch from CO₂ faster than plants can
The advance hints at sustainable, efficient factory production of food and industrial chemicals
Feeding the world uses enormous amounts of land, water, fertilizers, pesticides, and fuel. In a step toward more sustainable food production, researchers have designed a method to make starches from carbon dioxide more efficiently than plants do (Science 2021, DOI: 10.1126/science.abh4049).
The new technique, which relies on chemical catalysts and a curated combination of natural and engineered enzymes, converts CO2 to starch 8.5 times as efficiently as corn plants can.
This suggests that it is possible we can produce starch in a factory rather than on a farm, which should be a way to ensure human food security and reduce carbon dioxide emissions, says Yanhe Ma, a microbiologist at the Tianjin Institute of Industrial Biotechnology. The synthetic starch could find use in industrial applications and as an ingredient in animal or human food. [snip]
Not really even a huge job-creator manufacturing, I'd suppose, though perhaps for a niche global market???
