Inside the Factory Using Rocks & Sunlight to Fix AI's Power Problem | Exowatt

About this episode

Hannan Happi discusses Exowatt's innovative approach to solving the AI power crisis using solar energy and thermal storage.

Most announced data centers will never get built. The ones that do are running on gas generators. And the US grid has no answer for what's coming. Hannan Happi, CEO & Co-Founder of Exowatt, joins Sourcery for a rare facility tour of their 40,000 sq ft Miami HQ — walking us through the tech, the team, and why the AI power crisis is far worse than the headlines suggest. Exowatt has raised $140M from a16z, Felicis, Sam Altman, Leonardo DiCaprio, Starwood Capital, Thrive Capital, and more, all betting on a deceptively simple idea: concentrate sunlight with Fresnel lenses, store the heat in rocks at 1,000°C, and dispatch electricity on demand. 24 hours a day, no grid required. Their P3 system is built from sand, dirt, and steel. Like a large magnified glass and a rock. No lithium. No cobalt. No China. Target cost: 1 cent per kilowatt hour.
