Fusion researchers report a breakthrough in pursuit of nearly limitless energy

MuWave, a UK spinout from United Kingdom Atomic Energy Authority research, received £450,000 to develop terahertz microwaves intended to heat fusion plasmas; the work is aimed at commercializing the technology for fusion research including the UK’s STEP prototype planned for 2040.

MuWave, a United Kingdom company spun out of research by the United Kingdom Atomic Energy Authority, is developing very high‑power microwaves at terahertz frequencies to heat plasma for fusion experiments. A UK government news release says the approach aims to raise plasma temperatures above those in the sun’s core and to support fusion projects such as the STEP prototype, which is scheduled for 2040. The company was awarded £450,000 from the UK Innovation and Science Seed Fund to advance the technology. Researchers and officials note fusion remains at an early or experimental stage and that commercial electricity from fusion is years away. The team also says the microwave system could have uses beyond fusion research, including communications and imaging. Key facts: - MuWave is a spinout from United Kingdom Atomic Energy Authority research and is developing terahertz‑band microwaves for plasma heating. - The company received £450,000 from the UK Innovation and Science Seed Fund to support early commercialization efforts. - Government reporting describes the goal as heating fusion plasmas to temperatures higher than the sun’s core. - Common microwave ovens operate near 2.45 gigahertz; a terahertz is 1,000 times greater than a gigahertz, as noted in the report. - The report states the technology could also be applied to satellite communications, radar, geothermal drilling, and medical imaging. Summary: The announcement describes an early funding milestone for a technology intended to support fusion experiments and related applications. Reported next steps include using the funds to advance commercialization and integration with fusion research programs. Undetermined at this time are the precise timelines for experimental results or any broader deployment beyond research.
