This fucking sucks, the Great Satan needs to be forced to embrace the Great Seitan 
(so does the rest of the first world but Great Satan/Seitan was funnier)
Clean coal is fake as hell but China’s ultra-supercritical coal plants are legitimately about 15% more efficient than the overwhelming majority of western coal plants. It’s genuinely cool technology. If you make more energy per unit of coal, you can use less coal for the same energy.
It’s not-as-dirty coal. It’s also not really relevant for America. But it is neat
Yeah, totally irrelevant for the US and fossil fuel politics, I just wanted to talk about a cool thing.
So how does it work? Supercritical steam? Somehow it burns hotter? Have you seen the Douyin videos selling coal btw?
Basically, at supercritical pressures, the temperature drop converting it back to liquid water in the turbine results in a larger temperature drop, and thus more of the energy being translated into mechanical work. Ultra-supercritical means the temperature drop is even more dramatic than in other supercritical steam generators and thus even more efficient.
I have never seen a Douyin video, I don’t really do social media
Really interesting! Here’s a screenshot of the video https://twitter.com/pretentiouswhat/status/1668510500693614593
Oh, they’re just doing The Shopping Channel but for Business2Business sales
