News Summary

Fusion startup Thea Energy is pioneering a new design for fusion power plants with its Helios reactor, which is inspired by pixel technology. The company’s innovative approach uses specialized control software and a unique array of magnets to manage plasma, promising a more cost-effective and efficient solution compared to traditional fusion reactors. Thea Energy’s design leverages a dozen larger magnets and hundreds of smaller ones to create a ‘virtual’ stellarator, allowing for rapid iteration and adaptability in design. With ambitions to deliver 1.1 gigawatts of heat and convert it to 390 megawatts of electricity, Helios is positioned to be a competitive clean energy source. The startup is currently preparing to build its initial fusion device, Eos, to validate the science behind Helios and aims to announce a site for Eos in 2026, with operations expected around 2030.
