Thea Energy raises $20M Series A for pixel-inspired fusion power plants


The startup is betting that software can supplant manufacturing precision in its quest to deliver reliable, inexpensive fusion power.

The startup is betting that software can supplant manufacturing precision in its quest to deliver reliable, inexpensive fusion power. In tokamaks, the doughnut-shaped designs that many large reactor projects use, those magnets have to be built with incredible precision to be able to contain plasma and keep it at the right temperature. So instead they’re using an approach developed at the Princeton Plasma Physics Laboratory that lines a doughnut-shaped reactor with an array of high-temperature superconducting magnets each controlled by software.
