# Thea Energy

> Thea Energy, Inc. is a fusion energy company in Kearny, New Jersey, founded in 2022 out of
> Princeton University and the Princeton Plasma Physics Laboratory. It is reinventing the
> stellarator using a phased array of simple planar electromagnetic coils in place of complex
> 3D modular coils, moving field-shaping complexity from hardware into a software control
> stack. Its first integrated machine is Eos; the follow-on electricity-producing plant is
> Helios.
