Realta Fusion lights bulb with electricity recovered directly from nuclear fusion reaction
Wisconsin-based nuclear fusion startup Realta Fusion said it succeeded in recovering electricity directly from a fusion reaction and lighting bulbs. The company said it publicly demonstrated the method at its WHAM fusion test device and claimed it was the first private company to do so. Realta said it converted energy from alpha particles into electricity, producing about 100 volts and several amperes, and estimates direct conversion efficiency at about 90 percent.

SMR vs fusion vs renewables: three-way race for future power, who takes energy throne by 2035
Rising electricity demand driven by the spread of artificial intelligence is reshaping the global energy market and intensifying competition over power infrastructure. With gas turbine supply shortages expected to persist and geopolitical risks adding uncertainty, technology companies are exploring alternatives such as small modular reactors and nuclear fusion. Developers including Kairos Power, Oklo, Commonwealth Fusion Systems and Helion are pursuing demonstration and commercial timelines, while renewables and grid batteries gain cost competitiveness.
