Theia Labs

Theia Labs develops laser-based wireless power transfer (WPT) systems for advanced space missions. Founded in 2024 at TU Graz, the company emerged from an 18-month research project designing a wireless power system to help lunar rovers survive the 14-day lunar night. Today, our mission has evolved into building scalable optical power beaming solutions for satellites, robotic explorers, and future planetary infrastructure.

Our technology focuses on delivering precise, reliable energy where it is needed—from repowering CubeSats and SmallSats in Low Earth Orbit to beaming power from orbiting satellites to lunar rovers operating in permanently shadowed regions. By extending mission lifetimes and reducing reliance on onboard batteries or sunlight, we aim to make space operations more flexible, resilient, and sustainable.

Beyond space, we explore terrestrial applications including precision agriculture—using laser systems for selective, herbicide-free weed control—and other emerging dual-use opportunities. Theia Labs joined ESA BIC Austria in 2025 and is currently developing its first breadboard demonstrator using commercial off-the-shelf components to validate core concepts and prepare for future prototype integration.
