> Preliminary lab tests show that synthetic starch is about 8.5 times more efficient than starch produced by conventional agriculture. Under the condition of sufficient energy supply and current technical parameters, the annual production of starch of 1 cubic meter bioreactor is equivalent to the annual production of starch of 5 mu (0.33 hectare) of corn in China. Ah of course, leaving aside the small issue of energy…

Leaving aside the future improvements(50% larger plants) in agriculture as well:

Can anyone explain how this works?

See jarenmf's comment. Basically the CO2 is catalyzed into Methane using an 'inorganic catalyst', there is this paper[1] which uses a ruthenium catalyst at 400 degrees C to do it. Then the methane is consumed by some genetically modified bacteria (probably e.coli) first to convert it to an intermediate product, and then with a second organism to convert it into starch. In the article they talk about genetically modif…

Thanks. Isn’t it cheating to use bacteria? I thought this was all synthetic.

There may be places where you would want access to starches, agriculture is not feasible, transportation costs are prohibitive, but you also have abundant power. I’m struggling to think of a place that meets all those criteria.

Mars?

there's not much co2 on Mars

Most of the methane comes from cattle belching, so it's basically impossible to harvest at scale. The lagoons of manure also do, and that can be harvested though it's hard. https://climate.nasa.gov/faq/33/which-is-a-bigger-methane-so...

"CO2 is catalyzed into Methane using an 'inorganic catalyst', there is this paper[1] which uses a ruthenium catalyst at 400 degrees C" that either alchemy or more energy consuming than agriculture. "Silver-gray ruthenium metal looks like platinum but is rarer," - great to keep the costs down and avoid wars in places like congo eh? ;)

You are wrong. Please learn to check facts before posting, thanks.

That depends on how much energy is required. It does mean that settlements in places like the Yukon and Northern Alaska are now much more interesting.

I think energy is going to get a lot cheaper in the coming years. Especially at times when renewables are overproducing.

Wnich indicators do you see for that? Any data, facts, or is this just guessing?

Taking this news with a grain of salt, with obvious reasons.

Every time I read the Global Times I find myself wondering "how does a propaganda paper for a country with 1.4 billion people still not know how to write things that don't sound like blantant propaganda?"

You'd think, with all their resources, they could have hired someone a bit more learned in the gentle art of subtlety.
