Grid From Above, with Marc Berte (CEO of Overview Energy)
Valley of Depth
Problem Overview Energy Aims to Solve
Marc Berte frames the core problem: rising power demand and a grid that cannot move energy fast enough.
We're back to kick off 2026!
While the world debates how to power the next era of compute, data centers, and industrial growth, Overview Energy is betting the answer is above us. The company is building infrastructure to beam power from space directly to Earth's grid.
Founded by Marc Berte, a nuclear and aerospace engineer who spent his career at the intersection of lasers, spacecraft, and high-energy systems, Overview is developing a constellation of satellites in geosynchronous orbit that absorb sunlight, convert it to near-infrared laser light, and transmit it to existing utility-scale solar projects on the ground. No new receivers required. By using wide-beam, passively safe transmission and off-the-shelf ground infrastructure, Overview aims to deliver dispatchable, redirectable power anywhere on the planet, turning space solar from science fiction into grid-scale reality.
We discuss:
- Why space solar energy is finally viable after decades of false starts
- How Overview's architecture avoids the in-space assembly problem entirely
- How the economics work: matching cost curves to high-price markets first
- Why GEO matters more than LEO for grid-scale power delivery
- The role of launch cost as the critical external variable
- Why space solar could be the demand flywheel that drives launch costs down for everyone
