AmiMoJo shares a report from Electrek: The U.S. installed 50 gigawatts (GW) of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades. That’s enough to power 8.5 million households. According to the U.S. Solar Market Insight 2024 Year in Review report (PDF) released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, solar and storage account for 84% of all new electric generating capacity added to the grid last year.

In addition to historic deployment, surging U.S. solar manufacturing emerged as a landmark economic story in 2024. Domestic solar module production tripled last year, and at full capacity, U.S. factories can now produce enough to meet nearly all demand for solar panels in the U.S. Solar cell manufacturing also resumed in 2024, strengthening the U.S. energy supply chain. […] Total US solar capacity is expected to reach 739 GW by 2035, but the report forecasts include scenarios showing how policy changes could impact the solar market. […] The low case forecast shows a 130 GW decline in solar deployment over the next decade compared to the base case, representing nearly $250 billion of lost investment.

Longtime Slashdot reader schwit1 shares a report from Behind The Black: According to information at this tweet from anonymous sources, parts of Starship will likely require a major redesign due to the spacecraft’s break-up shortly after stage separation on its last two test flights. These are the key take-aways, most of which focus on the redesign of the first version of Starship (V1) to create the V2 that flew unsuccessfully on those flights:

– Hot separation also aggravates the situation in the compartment.
– Not related to the flames from the Super Heavy during the booster turn.
– This is a fundamental miscalculation in the design of the Starship V2 and the engine section.
– The fuel lines, wiring for the engines and the power unit will be urgently redone.
– The fate of S35 and S36 is still unclear. Either revision or scrap.
– For the next ships, some processes may be paused in production until a decision on the design is made.
– The team was rushed with fixes for S34, hence the nervous start. There was no need to rush.
– The fixes will take much longer than 4-6 weeks.
– Comprehensive ground testing with long-term fire tests is needed. [emphasis mine]

It must be emphasized that this information comes from leaks from anonymous sources, and could be significantly incorrect. It does however fit the circumstances, and suggests that the next test flight will not occur in April but will be delayed for an unknown period beyond.

NASA’s SPHEREx observatory is now in space for a two year year mission to create a 3D map of the entire celestial sky. The telescope left the ground on top of a Falcon 9 rocket from a launch pad in California, four years after NASA announced that a SpaceX flight will launch the mission, along with NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) microsatellites. SPHEREx separated from SpaceX’s vehicle at 12AM Eastern time on March 12 and will remain in low Earth orbit, where it will maintain a position relative to the sun that will remain the same throughout the year.

Every 98-minute orbit the observatory makes will allow it to view a 360-degree strip of the sky in both optical as well as near-infrared light. The telescope can capture more 360-degree strips as the Earth moves around the sun, enabling it to map the entire celestial sky within six months. SPHEREx was designed to image the entire sky every six months in two years, with its goal being to create a 3D map of over 450 million galaxies. The telescope will also image and gather information on over 100 million stars in the Milky Way.

SPHEREx’s map is bound to be colorful: It will separate infrared light emitted by the stars and galaxies into 102 individual colors using a technique called spectroscopy. NASA likens it to the “way a prism splits sunlight into a rainbow.” The agency says observing the objects in different colors will reveal various properties about them, such as their composition. For galaxies, their colors could help scientists determine their distance from our planet. The data SPHEREx provides will give scientists information about what happened right after the Big Bang and could provide evidence of cosmic inflation, or the rapid expansion of the early universe. SPHEREx will shed its telescope lens’ protective cover in four days and will start its science operations in a little over a month once its temperature has cooled down. 

Meanwhile, the four PUNCH satellites, which will also take on a Sun-synchronous orbit, will map the sun’s corona by taking polarized white-light images of the celestial object. It will gather data to help us better understand how the corona turns into solar wind, which could lead to accurate predictions of space weather events affecting spacecraft orbiting the Earth.

An anonymous reader quotes a report from TechCrunch: There’s a power crunch looming as AI and cloud providers ramp up data center construction. But a new report suggests that a solution lies beneath their foundations. Advanced geothermal power could supply nearly two-thirds of new data center demand by 2030, according to an analysis by the Rhodium Group. The additions would quadruple the amount of geothermal power capacity in the U.S. — from 4 gigawatts to about 16 gigawatts — while costing the same or less than what data center operators pay today. In the western U.S., where geothermal resources are more plentiful, the technology could provide 100% of new data center demand. Phoenix, for example, could add 3.8 gigawatts of data center capacity without building a single new conventional power plant.

Geothermal resources have enormous potential to provide consistent power. Historically, geothermal power plants have been limited to places where Earth’s heat seeps close to the surface. But advanced geothermal techniques could unlock 90 gigawatts of clean power in the U.S. alone, according to the U.S. Department of Energy. […] Because geothermal power has very low running costs, its price is competitive with data centers’ energy costs today, the Rhodium report said. When data centers are sited similarly to how they are today, a process that typically takes into account proximity to fiber optics and major metro areas, geothermal power costs just over $75 per megawatt hour. But when developers account for geothermal potential in their siting, the costs drop significantly, down to around $50 per megawatt hour.

The report assumes that new generating capacity would be “behind the meter,” which is what experts call power plants that are hooked up directly to a customer, bypassing the grid. Wait times for new power plants to connect to the grid can stretch on for years. As a result, behind the meter arrangements have become more appealing for data center operators who are scrambling to build new capacity.

Sphere Entertainment Co, the company behind the Las Vegas Sphere, said they are considering opening scaled-down versions of the immersive venue in other cities. AV Magazine reports: While this has been been feasible for its high-profile residencies such as U2, the Eagles, Dead & Company and Anyma, smaller venues could attract a broader range of artists who might not have the budget or demand to fill the flagship Las Vegas location. By scaling down the size while retaining the signature technology, Sphere Entertainment Co can offer a similar spectacle at a more sustainable cost for artists and spectators.

The possibility of mini-Spheres follows news that a full-scale venue will open in the UAE as a result of a partnership between Sphere Entertainment Co and the Department of Culture and Tourism — Abu Dhabi. Beyond concerts, the Las Vegas Sphere has proven successful with immersive films such as V-U2: An Immersive Concert Film and the Sphere Expeience featuring Darren Aronofsky’s Postcard from Earth, which In January passed 1,000 screenings. “As we enter a new fiscal year, we see significant opportunities to drive our Sphere business forward in Las Vegas and beyond,” said Dolan. “We believe we are on a path toward realizing our vision for this next-generation medium and generating long-term shareholder value.”

The franchise’s first animated, feature-length theatrical release The Day the Earth Blew Up finally opens this Friday.

MojoKid writes: AMD just launched its latest flagship desktop processors, the Ryzen 9 9950X3D. Ryzen 9 9950X3D is a 16-core/32-thread, dual-CCD part with a base clock of 4.3GHz and a max boost clock of 5.7GHz. There’s also 96MB of second-gen 3D V-Cache on board. Standard Ryzen 9000 series processors feature 32MB of L3 cache per compute die, but with the Ryzen 9 9950X3D, one compute die is outfitted with an additional 96MB of 3D V-Cache, bringing the total L3 up to 128MB (144MB total cache). The CCD outfitted with 3D V-Cache operates at more conservative voltages and frequencies, but the bare compute die is unencumbered.

The Ryzen 9 9950X3D turns out to be a high-performance, no-compromise desktop processor. Its complement of 3D V-Cache provides tangible benefits in gaming, and AMD’s continued work on the platform’s firmware and driver software ensures that even with the Ryzen 9 9950X3D’s asymmetrical CCD configuration, performance is strong across the board. At $699, it’s not cheap but its a great CPU for gaming and content creation, and one of the most powerful standard desktop CPUs money can buy currently.

With all the announcements from automakers planning for more gasoline and hybrid cars in their future lineups, you’d think that electric vehicles had stopped selling. While that might be increasingly true for Tesla, everyone else is more than picking up the slack. According to analysts at Rho Motion, global EV sales are up 30 percent this year already. Even here in the US, EV sales were still up 28 percent compared to 2024, despite particularly EV-unfriendly headwinds.

Getting ahead of those unfriendly winds may actually be driving the sales bump in the US, where EV sales only grew by less than 8 percent last year, for contrast. “American drivers bought 30 percent more electric vehicles than they had by this time last year, making use of the final months of IRA tax breaks before the incentives are expected to be pulled later this year,” said Charles Lester, Rho Motion data manager.

With the expected loss of government incentives and the prospect of new tariffs that will add tens of thousands of dollars to new car prices, now is probably a good time to buy an EV if you think you’re going to want or need one.
