Researchers at the National Institute of Standards and Technology (NIST) have reduced the time and energy required to cool materials to a few degrees above absolute zero. Their prototype device could save an estimated 27 million watts of power, $30 million in global electricity consumption and enough cooling water to fill 5,000 Olympic swimming pools. By modifying the pulse tube refrigerator (PTR) commonly used in research, the scientists cut down the time it takes to reach cryogenic temperatures by between one half and one quarter. Read more

An energy startup aimed at cleaning up artificial intelligence’s massive use of electricity is getting a multi-million dollar boost from investors, including OpenAI's CEO, Sam Altman. The company, Exowatt, develops shipping container-sized modules fitted with solar lenses that turn the sun’s energy into heat, which can warm up cheap material, and can be stored for up to 24 hours. The modules then produce electricity by passing the stored heat through an engine. The company’s goal is to benefit from cost reductions by storing energy as heat. Exowatt reportedly wants to offer electricity for as low as one cent per kilowatt-hour minus subsidies, and hopes to deliver its modules later this year. Read more
