Replying to @TIME
@TIME just named the @ExowattEnergy P3 one of the Best Inventions of 2026. 🔥 When we started Exowatt, people told us the answer to AI’s power problem was already decided: more gas, more batteries, maybe nuclear someday. We thought the answer was sitting right above us. The P3 is modular dispatchable solar. Custom Fresnel lenses turn sunlight into high-temperature heat. That heat goes into a long-duration heat battery , our "rocks in a box". And when the grid needs it, day or night, the heat is turned into electricity. This recognition belongs to the Exonauts, who took an idea most people called impossible and turned it into hardware shipping off a production line. You showed up every day to bend light, store heat, and prove the doubters wrong. Thank you! The sun delivers more energy in an hour than humanity uses in a year. We’re just getting started on using it. ☀️ @TIME #BestInventions #AI #DataCenters #Energy #Exowatt

Small drones with bad intentions are causing most casualties in combat and attacking civilian infrastructure far from any front line. Mara raised $7M, led by @khoslaventures, to shoot them all down, and fast, with the world's cheapest counter-swarm. Thank you @Forbes for the coverage.
