"Blue Frontier, a company based in Florida, is attempting to harness the cooling effects of evaporating water. Its approach makes use of a liquid desiccant, similar to ultra-salty brine, to remove moisture. The dried air is then split into two streams, one of which is passed over a thin layer of water to induce evaporation. This lowers the temperature of the surrounding metal, which in turn cools the other airstream before it is directed back into the room."

"While heat officers can advocate for policies, they often lack decision-making power within a city or regional government."

"If Netflix persuaded its suppliers to buy low-emissions equipment, it could prompt an industry-wide change. Netflix’s emissions are broadly in line with its industry peers, and its challenges are the same. The same shops that rent lights, portable power sources and vehicles tend to service productions across the various studios, and so more green tech for Netflix means more all around. And if the company succeeds in communicating to the makers of this equipment that a buyer exists, that would help de-risk the investment and encourage more adoption industry-wide."

"Incumbents are rushing to develop the technology for the grid, and several startups are betting big on it, too. Natron, an American firm backed by Chevron, an oil giant, is investing $1.4bn to build a sodium-ion battery factory in North Carolina, which is scheduled to open in 2027. Landon Mossburg, the chief executive of Peak Energy, another sodium-ion startup, says he wants his firm to be 'the CATL of America.'"

"The startup aims to eventually deploy thousands of its modular microreactors, though to date it has not brought any online. The first reactor might appear in Europe as soon as 2026, assuming Last Energy manages to meet its extremely aggressive construction, financial, and regulatory timelines — not a common occurrence in the nuclear industry. Venture capital heavyweight Gigafund led the round, which closed early this year but was revealed only today. The startup has raised a total of $64 million since its 2019 founding."

"The contract announced by BWXT on Monday will mark the start of a 'deployment phase,' essentially kicking off an exploration of options for the centrifuge pilot plant’s deployment. The engineering study aims 'to inform the acquisition approach for a pilot plant that will demonstrate the DUE centrifuge performance, reliability, and life-cycle costs for the NNSA. Fluor will be the engineering, procurement, and construction service provider for the activity,' BWXT said."

"Prescribed or controlled burns — fighting fire with fire — have long been used by indigenous groups to manage wildfire risk. Clearing excess vegetation reduces a forest’s fuel load, making it less likely a blaze will break out or spread quickly. But it’s a manpower-intensive process. BurnBot’s June burn covered an area the size of an American football field using a five-member crew; Chiverton says the same job sans robot would have needed 10 people."
