Realta Fusion generates electricity directly from a fusion reaction, an apparent first

Realta Fusion says it has demonstrated the ability to draw power directly from a fusion plasma, which CEO Kieran Furlong called a milestone showing what is possible. The company presents the result as an apparent first in efforts to turn fusion reactions into usable electricity.

If validated, the demonstration could strengthen confidence that fusion power can move beyond heat-generation concepts toward practical electricity production. It also highlights growing competition among fusion startups to prove not just plasma performance, but credible paths to commercial energy systems.
