Exclusive: Sam Altman-backed Exowatt wants to power AI data centers with billions of hot rocks | TechCrunch

▤ Summary

Exowatt raised an additional $50 million to extend its Series A round and support production scaling. The company is building a simple modular solar-thermal system designed to deliver low-cost, round-the-clock electricity for AI data centers. Its P3 units use concentrated solar power and thermal storage to provide continuous power for up to five days. The startup says it already has a large backlog and wants to reach massive production volumes to hit its one-cent-per-kWh target. The opportunity is strongest in sunny regions, especially where new data centers are being built.
