The bottleneck in geothermal moved from the drill to the turbine. This SpaceX alum raised $22M to fix it

The race to power artificial intelligence has a problem that solar panels and wind turbines cannot fix on their own: the electricity has to be there at 3am, in still air, under cloud. Critical Energy, a Los Angeles startup founded by a former SpaceX engineer, has raised $22mn to chase that always-on demand with geothermal, […]

Nashville Zoo says a proposed AI data centre could stop its endangered leopards from breeding

The Nashville Zoo has launched a campaign to block a 69,000-square-foot AI data centre proposed by Georgia-based DC BLOX on a site roughly 50 yards from the zoo’s animal enclosures. A petition against the project has drawn nearly 300,000 signatures in less than a week. Nashville’s Metro Council is now considering a data centre moratorium, […]

A UK startup says it can cut data centre network power by 81% by replacing every electrical switch with light

For decades, the networks inside data centres have run on electrical switches. They are power-hungry, generate enormous heat, and are increasingly the bottleneck that limits how fast AI systems can process and exchange data. Oriole Networks, a UK startup, says it has a fix: replace every electrical switch in the core network with nanosecond-scale optical […]

Berlin’s GALVANY raises €10M to fix Germany’s broken heat-pump market, and it’s already profitable

Germany has no shortage of heat pumps on paper. What it lacks is a way to get them sold, installed, subsidised, and paid off without the whole thing falling apart somewhere in the middle. GALVANY, a Berlin startup that runs the entire heat-pump journey from sale to installation to ongoing energy management, has raised €10mn […]
