Wireless device makes clean fuel from sunlight, CO2 and water:
The device, developed by a team from the University of Cambridge, is a significant step toward achieving artificial photosynthesis – a process mimicking the ability of plants to convert sunlight into energy. It is based on an advanced 'photosheet' technology and converts sunlight, carbon dioxide and water into oxygen and formic acid – a storable fuel that can be either be used directly or be converted into hydrogen.
The results, reported in the journal Nature Energy, represent a new method for the conversion of carbon dioxide into clean fuels. The wireless device could be scaled up and used on energy 'farms' similar to solar farms, producing clean fuel using sunlight and water.
[...] "It's been difficult to achieve artificial photosynthesis with a high degree of selectivity, so that you're converting as much of the sunlight as possible into the fuel you want, rather than be left with a lot of waste," said first author Dr Qian Wang from Cambridge's Department of Chemistry.
[...] this new technology is more robust and produces clean fuel that is easier to store and shows potential for producing fuel products at scale. The test unit is 20 square centimetres in size, but the researchers say that it should be relatively straightforward to scale it up to several square metres. In addition, the formic acid can be accumulated in solution, and be chemically converted into different types of fuel.
"We were surprised how well it worked in terms of its selectivity – it produced almost no by-products," said Wang. "Sometimes things don't work as well as you expected, but this was a rare case where it actually worked better."

You actually believe that shit. You've fallen so far most of the lesser demons have to look down to see you properly. How does it feel to know a teenage girl hundreds of miles away is not only a better person than you but also tirggering you 24/7/364.24-and-a-bit?

It does sadden me that people like him exist.
It does explain our current situation with the climate change and the Covid, both problems exacerbated by people intentionally misrepresenting science and treating gut feelings as truth.
Hell even Mike Max (a sports commentator) was able to understand that humid air, which feels "heavier," is actually lighter than regular air (leading to more home runs hit). I had to think about it for a bit, but then I realized that H2O was lighter than O2 and N2, so it actually made sense. Mike knew the stats, and so was at least able to accept that the air must be less dense (they didn't get into the chemistry on the air).
It was interesting hearing a sports commentator and a meteorologist discussing air density changing with humidity and coming up with the conclusion that the air must be less dense, despite the fact that it feels more dense, but for different reasons (Chemistry/meteorological knowledge and sports stats).

Oh OK I am the triggered one and you are the rational one. It really shows.

Yes, yes it does. Notice that one of us is going full /b/tard meme machine on a girl some 40% his age, front-loading said memetardedness with all kinds of strawmen, non-sequiturs, and ad homs...and the other of us is me.

A pity you are unable to see the irony of a possible tech development as exemplified by my "meme", but I don't want to sound defensive. Because being defensive means implicitly accepting your accusation resting on your own reconstruction of my personal feelings towards some media figure. So, thank you for confirming my previous statement.
