Reasonable minds may differ on the question of whether hydrogen fuel cells have a place in the clean-energy future. However, it’s a fact that the fossil fuel giants have been heavily hyping hydrogen, and it’s not hard to see why, as the vast majority of hydrogen is currently produced from natural gas.

Oil companies are working hard to appear “green,” but their true efforts are quite clear. Some will do whatever it takes to slow the pace of electrification.

The fossil fuel power plant that a private equity firm revived to mine bitcoin is at it again. Not content to just pollute the atmosphere in pursuit of a volatile crypto asset with little real-world utility, this experiment in free marketeering is also dumping tens of millions of gallons of hot water into glacial Seneca Lake in upstate New York.

“The lake is so warm you feel like you’re in a hot tub,” Abi Buddington, who lives near the Greenidge power plant, told NBC News.

Two important factors limiting Moore’s Law are power consumption and Coulomb interactions are interactions between electric charges that follow Coloumb’s law, an electrodynamics theory.

These interactions can be a major challenge for the development of nanoelectronic circuits. Quantum spin Hall (QSH) insulators are particularly promising materials for the development of low-power electronics, yet so far the impact of Coulomb interactions on nanocircuits made by these materials have only been examined theoretically, rather than experimentally.

Researchers at Nanjing University and Peking University have recently observed one-dimensional (1D) Coulomb drag between adjacent QSH edges separated by an air gap. Their paper, published in Nature Electronics, highlights the potential of QSH effects for suppressing the adverse effects of Coulomb interactions on the performance of nanocircuits.

The remains of 182 people in unmarked Indigenous graves were found on the eve of Canada Day.

The vehicle runs on regular fuel and can travel up to 1000km while airborne, its creator says.

The mosaic image is a composition of seven subsequent frames taken from Nellysford, Virginia, as the space station traversed the face of the sun at the speed of roughly 5 miles per second, which is about 18000 mph (29000 kph), according to a NASA photo description.

The six-hour and 45-minute spacewalk was the third for Pesquet and Kimbrough in less than two weeks as they completed work on augmenting the space station’s power systems. The iROSA panel deployed on Friday was the second of six new panels to be installed at the station.

Friday’s extravehicular activity (EVA) positioned the second iROSA opposite the first on the far left, or port side of the space station’s backbone truss. Now both the 2B and 4B power channels on the port 6 (P6) truss have the new arrays deployed.

The US power grid needs all of support it can get. Sad that some would stand in the way of progress.

There is no love lost between the notorious Koch brothers and the nation’s railroad industry, and the relationship is about to get a lot unlovelier. A massive new, first-of-its-kind renewable energy transmission line is taking shape in the Midwest, which will cut into the Koch family’s fossil energy business. It has a good chance of succeeding where others have stalled, because it will bury the cables under existing rights-of-way using railroad rights-of-way and avoid stirring up the kind of opposition faced by conventional above-ground lines.

The Koch brothers and their family-owned company, Koch Industries, have earned a reputation for attempting to throttle the nation’s renewable energy sector. That makes sense, considering that the diversified, multinational firm owns thousands of miles of oil, gas, and chemical pipelines criss-crossing the US (and sometimes breaking down) in addition to other major operations that depend on rail and highway infrastructure.

Plans call for the 289-meter-tall (954-foot-tall) Baihetan Dam to have 16 generating units with a capacity of 1 million kilowatts each. That will make it second in size after the Three Gorges Dam, opened in 2003 on the Yangtze, with 22.5 million kilowatts of generating capacity.

BEIJING (AP) — The first two generating units of the world’s second-biggest hydroelectric dam were officially turned on Monday in southwestern China, the government announced.

The Baihetan Dam on the Jinsha River, a tributary of the Yangtze, is part of Chinese efforts to curb surging fossil fuel demand by building more hydropower capacity at a time when dams have fallen out of favor in other countries due to environmental complaints.
