Avalanche Energy, a fusion energy startup creating modular fusion micro-reactors, revealed today that it had reached a record 200 kilovolts in its micro-fusion reactor and closed a USD 40 million Series A financing led by Lowercarbon Capital with significant participation from Founders Fund and Toyota Ventures. Grantham Foundation, Clear Path, and Congruent Ventures also made investments in the Seed round after them. Autodesk, MCJ Collective, and the Climate Capital Syndicate were additional new participants. The University of Wisconsin at Madison’s 2006 experiment that produced 190 kilovolts produced the highest known operating voltage of any fusion device until Avalanche recently operated their second prototype reactor with 200 kilovolts.
The funding, which comes after the company’s 2021 USD 5 million seed round led by Prime Impact Fund, will be used to keep up with the company’s accelerated work to test, develop, and optimize its high-voltage orbitron prototypes as well as miniaturize critical parts necessary to deliver a stand-alone, micro fusion reactor.

“This is a huge step that validates the rapid technical progress this team has made in just a year and a half,” said Robin Langtry, CEO and co-founder of Avalanche Energy. “We are developing small-scale fusion using a test-fail-fix methodology, similar to the development of rocket engines, and it’s tremendously thrilling to watch our hardware concepts go from design to test in only a few days. We will be able to scale up and conduct more tests more quickly thanks to this fresh round of funding, which will eventually allow us to provide energy-producing micro-fusion reactors.
To confine the fusion fuel ions in precessing elliptical orbits at extremely high velocities, the company’s orbitron design is based on specialized electrostatic ion traps operated at hundreds of kilovolts. As one ion moves through the orbit of another ion inside the orbitron device, it has tens of millions of chances to fuse. Co-condensing high-energy electrons in the same orbital direction raises the density of ions. Eventually, non-fusing ions will deorbit and leave the apparatus.
