Finnish scientists have fed hydrogen to bacteria and gathered the end product which turns out to be protein.

This farm free technology is expected to be mainstream by 2030, so we’ll all be eating this stuff, called Solein, pretty soon. It’s cheaper than soya and no beans are harmed in the process.

As to the science behind it, I still can’t quite understand how pea burgers work, so Solein is completely beyond me. I can just imagine that its quite a lot of bacteria required to form a quarter pounder bactburger!
