    Petroleum Drilling Technology Is Now Making Carbon-Free Power
    An anonymous reader quotes a report from NPR: There's a valley in rural southwest Utah that's become a hub for renewable energy. Dozens of tall white wind turbines whoosh up in the sky. A sea of solar panels glistens in the distance. But the new kid on the block is mostly hidden underground. From the surface, Fervo Energy's Cape Station looks more or less like an oil derrick, with a thin metal tower rising above the sagebrush steppe. But this $2 billion geothermal project, which broke ground last year, is not drilling for gas. It's drilling for underground heat that CEO Tim Latimer believes holds the key to generating carbon-free power -- lots of it. "Just these three well pads alone will produce 100 megawatts of electricity. Around-the-clock, 24/7 electricity," he said. Latimer stood overlooking the project, which is currently under construction, on one of the drill rig's metal platforms 40 feet off the ground. This well is one of the 24 Fervo is in the process of completing at Cape Station to harness the Earth's natural heat and generate electricity. This isn't the type of geothermal that's already active in volcanic hot spots like Iceland or The Geysers project in California. It's called an enhanced geothermal system. Cold water goes down into a well that curves like a hockey stick as it reaches more than 13,000 feet underground. Then the water squeezes through cracks in 400-degree rock. The water heats up and returns to the surface through a second well that runs parallel to the first. That creates steam that turns turbines to produce electricity, and the water gets sent back underground in a closed loop. This horizontal well technique has been pioneered at a $300 million federal research project called Utah FORGE located in this same valley, which has paved the way for private companies to take the tech and run with it. Recent innovations like better drill bits -- made with synthetic diamonds to eat through hard subterranean granite -- have helped Fervo drill its latest well in a quarter of the time that it took just a couple of years ago. That efficiency has meant an 80% drop in drilling costs, Latimer said. Last year, Fervo's pilot project in Nevada used similar techniques to begin sending electricity to a Google data center. And the company's early tests at Cape Station in Utah show the new project can produce power at triple the rate of its Nevada pilot. "This is now a proven tech. That's not a statement you could have made two or three years ago," Latimer said. "Now, it just comes down to how do we get more of these megawatts on the grid so we have a bigger impact?" The report notes that Fervo signed a landmark deal with Southern California Edison, one of the country's largest electric utilities with 15 million customers. "It will send the first 70 megawatts of geothermal juice to the grid in 2026," reports NPR. "By the time the project is fully completed in 2028, this Utah plant will deliver 320 megawatts total -- enough to power 350,000 homes. The project's full output will be 400 megawatts."

    Amazon Joins Push For Nuclear Power To Meet Data Center Demand
    Amazon said on Wednesday it has signed three agreements on developing the nuclear power technology called small modular reactors, becoming the latest big tech company to push for new sources to meet surging electricity demand from data centers. From a report: Amazon said it will fund a feasibility study for an SMR project near a Northwest Energy site in Washington state. The SMR is planned to be developed by X-Energy. Financial details were not disclosed. Under the agreement, Amazon will have the right to purchase electricity from four modules. Energy Northwest, a consortium of state public utilities, will have the option to add up to eight 80 MW modules, resulting in a total capacity up to 960 MWs, or enough to power the equivalent of more than 770,000 U.S. homes. The additional power would be available to Amazon and utilities to power homes and businesses. "Our agreements will encourage the construction of new nuclear technologies that will generate energy for decades to come," said Matt Garman, CEO of Amazon Web Services. SMRs will have their components built in a factory to reduce construction costs. [...] Amazon said it is also leading a funding round for $500 million to support X-Energy's development of SMRs. Amazon and X-Energy aim to bring more than 5 gigawatts online in the United States by 2039, which the companies call the largest commercial deployment target of SMRs yet. Amazon also signed an agreement with Dominion Energy, opens new tab to explore the development of an SMR project near the utility's existing power station in Virginia. The about 300 megawatt project would help meet power needs in a region where demand is expected to jump 85% in 15 years, Dominion said.

    Amazon Finally Has a Color Kindle
    Amazon has unveiled its first color e-reader, the Kindle Colorsoft Signature Edition, priced at $279.99. The 7-inch device, available for preorder with shipments starting October 30th, utilizes E Ink's Kaleido technology and a new display stack. Kevin Keith, head of Kindle products, claims the Colorsoft maintains Kindle's hallmark features while introducing color without compromising performance. The e-reader boasts a 300ppi screen, enhanced LED pixels, and improved light distribution for vivid colors. It offers faster page turns and book openings compared to previous models. The color screen enhances the user interface, allowing for full-color book covers and a more vibrant standby display.
