Step aside, plant-based meat.

Space Bugs

While several startups are already selling "meat" made from plants, California's Air Protein says it's figured out how to make meat from thin air — by building on an idea NASA had in the 1960s.

According to Air Protein's website, NASA thought it might be able to use microbes called hydrogenotrophs to created a closed-loop feeding system for astronauts in space. The astronauts would breathe out carbon dioxide, which the microbes could eat and convert into nutrients that the astronauts could then eat, starting the cycle over again.

Down to Earth

That research never made its way into space.

But Air Protein found that it could feed hydrogenotrophs a combination of CO2 and other nutrients inside fermenting units here on Earth. The result: a brown powder that might not exactly look like meat — or even taste like, well, much of anything — but that's rich in nutrients and boasts the same amino acid profile as animal meat.


The company says the process takes just days and could be the environmentally friendly alternative to traditional meat production that humanity so desperately needs.

"The world is embracing plant-based meat," CEO Lisa Dyson said in a press release shared on Tuesday, "and we believe air-based meat is the next evolution of the sustainably-produced food movement that will serve as one of the solutions to feeding a growing population without putting a strain on natural resources."
