1. Exowatt, a company led by Hannan Happi, aims to provide cheap solar power for data centers and the broader energy market with their innovative technology called P3. The goal is to achieve one cent per kilowatt-hour.

2. To scale production towards this goal, Exowatt has raised an additional $50 million in funding, led by MVP Ventures and 8090 Industries. They aim to manufacture millions and eventually billions of P3 units annually to reach the target.

3. The P3 system involves using lenses and a Stirling engine within shipping container-sized boxes to convert sunlight into continuous power. The technology, known as concentrated solar or thermal solar, can store heat for up to five days for uninterrupted operation. It has potential advantages over existing solar and battery technologies, particularly in regions with high sunshine, but may have limitations regarding land requirements and regional availability.
