Wine fans have a reason to smile today. Wine 11.0 is finally here, and it is a big deal for anyone running Windows software on Linux. After a full year of work, more than six thousand code changes, and hundreds of bug fixes, Wine is moving forward in a way that feels like a turning point. This release tightens up major subsystems, improves performance, expands hardware support, and carries a big win for compatibility. If you have been waiting for Wine to feel smoother and a little less fussy, 11.0 might be the moment you jump back in.

Nuclear engineer Lonnie Johnson worked on NASA's Galileo mission, has more than 140 patents, and invented the Super Soaker water gun. But now he's working on "a potential key to unlock a huge power source that's rarely utilized today," reports the Atlanta Journal-Constitution.

Waste heat... The Johnson Thermo-Electrochemical Converter, or JTEC, has few moving parts, no combustion and no exhaust. All the work to generate electricity is done by hydrogen, the most abundant element in the universe. Inside the device, pressurized hydrogen gas is separated by a thin, filmlike membrane, with low pressure gas on one side and high pressure gas on the other. The difference in pressure in this "stack" is what drives the hydrogen to compress and expand, creating electricity as it circulates. And unlike a fuel cell, it does not need to be refueled with more hydrogen. All that's needed to keep the process going and electricity flowing is a heat source.

As it turns out, there are enormous amounts of energy vented or otherwise lost from industrial facilities like power plants, factories, breweries and more. Between 20% and 50% of all energy used for industrial processes is dumped into the atmosphere and lost as waste heat, according to the U.S. Department of Energy. The JTEC works with high temperatures, but the device's ability to generate electricity efficiently from low-grade heat sources is what company executives are most excited about. Inside JTEC's headquarters, engineers show off a demonstration unit that can power lights and a sound system with water that's roughly 200 degrees Fahrenheit — below the boiling point and barely warm enough to brew a cup of tea, said Julian Bell, JTEC's vice president of engineering. Comas Haynes, a research engineer at the Georgia Tech Research Institute specializing in thermal and hydrogen system designs, agrees the company could "hit a sweet spot" if it can capitalize on lower temperature heat...

For Johnson, the potential application he's most excited about lies beneath our feet. Geothermal energy exists naturally in rocks and water beneath the Earth's surface at various depths. Tapping into that resource through abandoned oil and gas wells — a well-known access point for underground heat — offers another opportunity. "You don't need batteries and you can draw power when you need it from just about anywhere," Johnson said. Right now, the company is building its first commercial JTEC unit, which is set to be deployed early next year. Mike McQuary, JTEC's CEO and the former president of the pioneering internet service provider MindSpring, said he couldn't reveal the customer, but said it's a "major Southeast utility company." "Crossing that bridge where you have commercial customers that believe in it and will pay for it is important," McQuary said...

On top of some initial seed money, the company brought in $30 million in a Series A funding in 2022 — money that allowed the company to move to its Lee + White headquarters and hire more than 30 engineers. McQuary said it expects to begin another round of fundraising soon.

"Johnson, meanwhile, hasn't stopped working on new inventions," the article points out. "He continues to refine the design for his solid-state battery..."

While Australia debates the merits of going nuclear and frustration grows over the slower-than-needed rollout of solar and wind power, China is going all in on renewables.

New figures show the pace of its clean energy transition is roughly the equivalent of installing five large-scale nuclear power plants worth of renewables every week.

A report by Sydney-based think tank Climate Energy Finance (CEF) said China was installing renewables so rapidly it would meet its end-of-2030 target by the end of this month — or 6.5 years early.

It's installing at least 10 gigawatts of wind and solar generation capacity every fortnight.

By comparison, experts have said the Coalition's plan to build seven nuclear power plants would add fewer than 10GW of generation capacity to the grid sometime after 2035.

Energy experts are looking to China, the world's largest emitter, once seen as a climate villain, for lessons on how to go green, fast.

"We've seen America under President Biden throw a trillion dollars on the table [for clean energy]," CEF director Tim Buckley said.

"China's response to that has been to double down and go twice as fast."

Rep. Alexandria Ocasio-Cortez, D-N.Y., has issued a dire warning to her party about the chaos that could ensue if they succeed in pushing President Joe Biden off the ticket. And she criticized Democrats who’ve given off-the-record quotes that suggest the party has resigned itself to a second Trump term.

In an Instagram Live video on Thursday, Ocasio-Cortez warned liberals that a brokered convention could lead to chaos, in part because she says some of the Democratic “elites” who want Biden out also don’t want Vice President Kamala Harris as the nominee in his place. 

“If you think that is going to be an easy transition, I’m here to tell you that a huge amount of the donor class and these elites who are pushing for the president not to be the nominee also do not want to see the VP be the nominee,” she said. 

Ocasio-Cortez claimed none of the people she’s spoken with who are calling on Biden to drop out — including lawmakers and legal experts — have articulated a plan to swap out the nominee without minimizing the serious legal and procedural challenges that are likely to ensue. 

Ocasio-Cortez also highlighted the racial, ethnic and class divisions that appear to have formed between the majority of those pining to blow up the ticket — led mostly by white Democrats and media pundits — and those elected officials who feel they and their constituents have too much at stake to upend the process at this point and so are willing to do the work to re-elect Biden-Harris. She alluded to this cultural divide in her video when she spoke out against anonymous sources expressing a sense of fatalism on behalf of Democrats about what might happen if Biden remains on the ticket: 

What I will say is what upsets me is [Democrats] saying we will lose. For me, to a certain extent, I don’t care what name is on there. We are not losing. I don’t know about you, but my community does not have the option to lose. My community does not have the luxury of accepting loss in July of an election year. My people are the first ones deported. They’re the first ones put in Rikers. They’re the first ones whose families are killed by war.
