Fusion cant come fast enough.

There are so many revolutionary technologies that are stored somewhere unused because they are not economical for the energy cost.

Fusion would catapult human civilisation to new heights. *insert meme, just wait for another 4 decades..*

You don’t need fusion for this. We can get more than enough energy for this sort of application from the energy tech we have today.

Fusion is about making energy cheap. This new technology from what I see, requires a lot of energy which will makes it economically unviable for business. This will remain in the lab and hopefully in 10 years, the scientists will have managed to reduce energy requirements.

Truly revolutionary stuff

Uhh...the extreme physics and engineering that would need to go into making fusion work is a lot more expensive than expanding solar, wind, and even fission.

It would be interesting to know how much energy went into making a kcal of starch compared to the usual means through planting crops. ​

BEIJING, Sept. 24 (Xinhua) -- Chinese scientists have developed an artificial method of synthesizing starch from carbon dioxide, the first of its kind globally.
The study, conducted by the Tianjin Institute of Industrial Biotechnology under the Chinese Academy of Sciences, was published in the journal Science on Friday.
As a major component of food, starch is generally produced by crops through photosynthesis. Starch synthesis in nature needs about 60 metabolic reactions and complex physiological regulation.
Many studies have been carried out globally on starch synthesis, but little progress had been made before.
The research team has designed an artificial starch synthesis pathway consisting of only 11 core reactions, achieving complete synthesis from carbon dioxide to starch molecules in the laboratory for the first time, said Ma Yanhe, Director General of the Tianjin Institute of Industrial Biotechnology.
The structure of the synthetic starch was proved to be the same as that of natural starch, said Ma, who is also the corresponding author of the study. Enditem

Very good point, I'd imagine initially it would need very high energy and over time be more and more efficient

But you forgot something very important point, this process doesn't need huge landmass, huge water, insecticide, labour, etc to plant the crops

I wonder if they can synthesize amino acids as a next step.

Thats the logical step .... and the good thing is the energy to do that can be sourced from solar farm in the middle of the desert ... including in Sahara

The biggest issues with the solar farm now is to integrate it into the Grid and and store it, with this technology, food issues might become in the past
