Our Everlight system replaces heavy solar panels and batteries on satellites with wireless laser-based power transmission — enabling lighter, more capable missions with continuous power delivery, even in eclipse zones and deep space.
The network includes:
- Hyperion – solar-powered laser transmitters in orbit
- IRIS – relay satellites that route laser energy across orbits
- EOS – compact receiver modules integrated into client satellites
We’re planning to offer scalable, on-demand orbital power for satellite constellations, space stations, and interplanetary missions. Power will be sold on a per-kWh basis, creating a new utility layer in space.
Founded in Germany with global operations, we’re currently at TRL 4, with a TRL 7 orbital demo planned via Falcon 9. Exlumina is the only company purpose-built for space-to-space energy delivery.
Our mission: to build the infrastructure for a Kardashev Type II civilization.
With Everlight, spacecraft can:
- Reduce launch mass by up to 40%
- Access 2–5× more available power for payloads
- Operate continuously in shadowed or deep-space environments
We’re advancing through TRL 4 prototypes toward our first orbital demo in 2026 — building the energy infrastructure for the final frontier.
Status Comment
Pivoted in 2025 from rockets to space-to-space power beaming.
