Comment Re:Balding won't _kill_ you! (Score 2) 29

Was at a party one time where some skinhead was showing off his new racist head tat. Someone asked why he got it on his head and he said, "When I have kids I can grow my hair and they'll never see it.

Someone nearby started laughing uproariously and said, "You idiot, both your grandfathers and you father were all bald by the time they were 40!"

Comment Alpamayo? Really? (Score 1) 11

Not sure what they were thinking, Alpamayo is one of the most dangerous climbs in the Andes. Beautiful mountains, but the death toll of the Cordillera Blanca is appalling. A single 1970 avalanche covered the entire town of Yungay and killed an estimated 20,000 people, while earlier avalanches have wiped out multiple other towns.

Really? Covering up the Gaza genocide is a leftist position now? Supporting the Iraq war was leftist? Burying stories about Dow, ADM and Monsanto was leftist? Pretending that no one could predict the Mortgage Meltdown or the Dot Bomb so no one should be prosecuted was leftist? Etc. etc. etc.

Yeesh, I'd hate to see what it takes to qualify as 'right wing' in your book.

Submission + - Supercritical CO2 Generators Now In Production 1

cusco writes: https://kdwalmsley.substack.co...

Chinese engineers deployed the world's first commercially viable sCO2 power generators, at a steel mill in Guizhou.

The Supercritical Carbon Dioxide (sCO2) generator converts waste heat into electricity. Compared to traditional steam and thermal systems, the sCO2 design is more than 85% more efficient, and produces 50% more electricity. . .

SCO2 is supercritical carbon dioxide. CO2 that’s maintained in a state above critical temperature and pressure, which is over 31 degrees Celsius and 1070 psi. Once there, CO2 acts both as a liquid and as a gas, and in industrial applications, that becomes very useful. As a gas, there is less resistance, and as a liquid, it provides greater thrust. And, turning CO2 into supercritical CO2 is more energy efficient than turning water into steam. . .

Not everyone is as optimistic. Long article which assumes the Chinese will be sloppy with implementation for some reason.

Experience with hydrogen suggests that expecting seals to remain effectively perfect over many years of continuous high pressure operation is absurdly optimistic, and there is little reason to assume supercritical CO systems will escape a similar long term reality. . .

I'm not sure how B follows A

Ever seen a consumer recycling operation? It's a miserable, dangerous, low paying job mostly staffed by illegals because rather than pay worker's comp the company can get them deported (much like the meat industry), the sooner it's automated the better. Plastics are particularly problematic for them, because while almost all of them have the "recyclable" symbol on them it's difficult to tell the various types apart so most of them get incinerated.

Robots and AI can sort and separate different types of materials far faster, more efficiently and more accurately than humans. New spectrographs can analyze a fragment of something almost instantaneously, allowing separation of the various types of plastics. All three innovations are already being used in commercial recycling in Europe (like construction waste and factory scraps). Consumer recycling is a considerably more difficult nut to crack, but China seems poised to make it work. It will be interesting to see.

That's been the secret to China's success, sure they have companies which pursue the high-profit industry segments, but they have a plethora of companies which are content with a much lower return like REE and a government which supports their effort. With their galloping advances in robotics and AI it would be surprising if they don't become the world leader in consumer waste recycling very soon.
