. implies the war will be escalated. Like it or not, US will be part of it in supporting Israel.IRAN CAN NOT HAVE A NUCLEAR WEAPON
Stocks pushed higher after the Wall Street Journal reported that Iran has been urgently signaling that it seeks an end to hostilities and resumption of talks over its nuclear programs.
Reuters has been told that Iran has asked Qatar, Saudi Arabia and Oman to press US President Donald Trump to use his influence on Israel for an immediate ceasefire in return for Tehran’s flexibility in talks about its nuclear program.
The U.S. pioneered the combination of solar panels and batteries that makes it possible to get power from the sun when it isn’t shining. Now it risks being left behind thanks to a trade war and Republicans’ plan to withdraw clean-energy subsidies.
The tax bill passed by the House would phase out tax breaks for various green technologies, including energy storage facilities that use batteries to store power that gets released when the grid needs it. Grid batteries are also heavily exposed to tariffs because, unlike EV batteries, practically none are made in the U.S. They are made in China.
This double whammy casts a shadow over a technology that is doing the heavy lifting as U.S. power demand rises for the first time in a generation. Batteries will account for 29% of the power capacity installed this year, behind only solar, the Energy Information Administration says.
The Senate may prolong the tax credits, and Wednesday’s court ruling that voided—for now—many of Trump’s tariffs underscores the uncertainty over trade policy. For green-energy companies that typically line up customers before committing to projects, that uncertainty makes it harder to put a price on power: “We have never seen such a high demand for energy, but there’s no way we can move forward,” said David Ruiz de Andrés, chief executive of solar-plus-storage company Grenergy.
The Madrid-based company has ambitions to grow in the U.S., lured by tech companies vying to build power-hungry data centers, but currently it isn’t investing in projects besides a few already under way. Grenergy’s new $4 billion investment plan prioritizes Europe, its home market, and Latin America, where it recently signed a deal with Chile’s state-controlled copper-mining giant, Codelco, to provide round-the-clock power from vast solar and battery arrays.
Solar power, 24/7 is becoming feasible (in very sunny places like Chile, anyway) thanks to battery technology improvements from Chinese manufacturers such as BYD and CATL. Their race to squeeze more capacity into less space reduced grid batteries’ cost by 40% between 2023 and 2024, according to BloombergNEF.
Not doomed, but more expensive-
Low costs, and the sheer availability of solar panels and batteries, means U.S. growth would likely be slowed rather than halted by trade barriers and withdrawn subsidies, said BloombergNEF policy expert Ethan Zindler: “Some projects will get canceled, some will go forward and get priced higher,” he said.
There aren’t enough gas turbines, let alone nuclear plants, to meet U.S. power demand. As Zindler sees it, the question is how much potential demand is destroyed by higher prices—tech companies can build more data centers in other countries—and how much Americans pay for electricity.
andMicrosoft made a significant statement by entering a twenty-year agreement with Constellation Energy, which plans to reopen the Three Mile Island nuclear plant, the site of the 1979 partial nuclear meltdown. Constellation Energy plans to invest $1.6 billion to refurbish and restart the reactor by 2028 with an estimated 835 MW of capacity. Microsoft entered the agreement to provide the energy demands for its AI data centers.
how about the moon:There is one problem with this: we cannot continue to scale energy usage like this without making the Earth inhospitable to organic life.
https://palladiummag.com/2025/04/18/the-moon-should-be-a-computer/we will in just a few short decades be able to deliver payloads of a self-assembling farm of robots to mine the Moon, create chip fabs, build, and ultimately tile the Moon with GPUs. The Moon has a surface area of 14.6 million square miles, roughly the size of Asia. If we very conservatively tiled even half the Moon with GPUs and solar panels, the Moon could sustain a billion times the compute of the Colossus cluster and, with a few turns of Moore’s law driving chip technology forward, even a trillion times the compute.
Comment: Stupid, STUPID, STUPID !!!The Trump administration is planning to close a small, obscure laboratory whose work undergirds everything from microchip manufacturing to nuclear fusion.
The Atomic Spectroscopy Group at the National Institute of Standards and Technology (NIST) provides the definitive measurements of atomic spectra. Spectra are specific sets of colors emitted by different atomic elements. Those sets of colors act as atomic fingerprints that are used to characterize a wide variety of things — from the gases in far-off stars, to the blood in a person's finger.
The laboratory has been in continuous operation for more than 120 years, but in mid-April it will be forced to close, according to a letter sent by the lab's head, Yuri Ralchenko, to dozens of colleagues around the world.
"We were recently informed that unless there is a major change in the Federal Government reorganization plans, the whole Atomic Spectroscopy Group will be laid off in a few weeks," Ralchenko wrote in the letter, which was emailed on March 18 and seen by NPR. The letter was first reported by Wired. Ralchenko says in the letter that he was told "our work is not considered to be statutorily essential for the NIST mission."
But thousands of scientists and engineers disagree. A petition is now circulating to reverse the closure, and it had received close to 3,000 signatures as of Wednesday. Among the signatories is Nobel Prize-winning physicist Sheldon Glashow.
"I cannot believe that the government would be stupid enough" to slash this kind of work, Glashow said in a video statement. The overwhelming support exists because the group's spectral measurements get used in almost every field imaginable, according to Elizabeth Goldschmidt, a physicist at the University of Illinois, Urbana-Champaign. "You look at the very specific color of a star, it can tell you the makeup of the star. You look at the blood in someone's finger ... and that can tell you how much oxygen is in the blood," she says.
But to measure colors accurately, devices like telescopes and pulse oximeters must be correctly calibrated, and that's where the Atomic Spectroscopy Group comes in. The laboratory maintains a database of atomic spectra that are the standard reference used to ensure devices are functioning correctly. Every month, the database receives around 70,000 queries from around the world, according to a recent post about it on NIST's website — and it's cited in two research papers per day, according to a recent presentation by Ralchenko.
Among the researchers querying the database is Brett Morris, an astronomer at the Space Telescope Science Institute in Baltimore, Md. who works on NASA's James Webb Space Telescope. Morris is studying planets around distant stars. Sometimes he says, the light coming from those stars looks surprising. "The first thing you have to do is to figure out who's to blame — was it oxygen? Was it carbon? Was it neon?" he says. "And the resource for doing that is the database produced by the Atomic Spectroscopy Group."
In addition, the laboratory conducts precise measurements of ultraviolet atomic spectra that are critical to developing advanced microchips. Ultraviolet light is used to etch tiny circuits, and advances in the field require detailed knowledge of the atomic spectra of elements in the extreme ultraviolet. There are a handful of facilities that research ultraviolet spectra, and this group is one of them, Goldschmidt says. It also studies plasmas, which are ionized gases that enshroud nuclear fusion reactions. Researchers around the world are pursuing fusion as a clean and virtually limitless form of energy, and detailed knowledge of plasmas is essential to that development.
Neither NIST nor its parent agency, the Department of Commerce, responded to NPR's inquiries about the closure, but the savings from closing the lab would be minimal. NIST's annual budget is just $1.5 billion, less than 0.02% of the government's $7 trillion annual budget.

Within NIST, the atomic spectroscopy group is made up of seven full-time federal employees. The group's employees even pay out of pocket for coffee and sugar used in its coffee breaks and have been doing so since 1973, according to a video celebrating its anniversary last year. By contrast, if the spectroscopy group closes, the costs will be enormous, scientists say. Researchers around the world will waste hours on the internet hunting around for the best spectral measurements, says Evgeny Stambulchik, a physicist at the Weizmann Institute of Science in Israel.
What currently takes a couple of minutes might soon take "many hours, maybe many days," Stambulchik says. "Multiply that several hours by several thousands of scientists and you understand the waste of work time there would be without such a centralized database," he says.
But Goldschmidt says the real blow would be to industry. Having centralized and agreed-upon calibration and measurement standards "is what allows industries to innovate and make new products," she says. "Everyone wins when this happens at NIST because everyone can rely on what NIST does, and they don't have to invest their time and money in doing it themselves."
