Thea Energy is building an economical and scalable fusion energy system utilizing arrays of mass-manufacturable magnets and dynamic software controls. Commercial fusion energy can uniquely provide a limitless source of zero-emission power for a sustainable future.
Thea Energy is leveraging recent breakthroughs in computation and controls to reinvent the stellarator, a scientifically mature form of magnetic fusion technology. Thea Energy was founded in 2022 as a spin-out of the Princeton Plasma Physics Laboratory and Princeton University, where the stellarator was originally invented. Thea Energy is currently designing its first integrated fusion system, Eos, based on its planar coil stellarator architecture which will produce fusion neutrons at scale and in steady state.

Quaise develops millimeter wave drilling systems for deep geothermal heat access. Our technology is the only approach in the world with the potential to build geothermal wells at unprecedented depths and temperatures.
By targeting depths up to 20 kilometers and temperatures up to 500 degrees Celsius, we will have the ability to build clean electric generation and heat distribution plants within a short distance of every major population and industrial center on the planet, at a fraction of the footprint of other renewables.
And by scaling through the established supply base of the fossil fuel industry, we will be able to achieve the terawatt-level annual deployments that will be required to successfully decarbonize our global energy system.
