Early Tesla and SpaceX investor Steve Jurvetson is backing Ambrosia Energy, a startup founded by former SpaceX executives Ben Longmier and Sara Spangelo. The company aims to solve artificial intelligence's growing electricity demand through off-grid solar and battery systems for data centres. Jurvetson's venture firm DFJ Growth announced the investment on Wednesday. Ambrosia targets electricity costs of around $100 per megawatt-hour with 99.9% availability and deployment within one year. The startup vertically integrates land acquisition, permitting, engineering, battery manufacturing, and construction. Its system combines solar power with 24-hour lithium-iron-phosphate battery storage, using a proprietary installation method designed to deploy panels 12 times faster than conventional approaches. Spangelo and Longmier previously co-founded Swarm Technologies, which SpaceX acquired in 2021. Ambrosia's next project targets 200 MW of solar capacity delivering 20 MW of continuous power.
