A major technical problem in the development of fusion reactors has been overcome. Scientists working at an experimental reactor in San Diego have solved the problem of plasma containment.

Before this breakthrough, plasma would leak out of it’s container and cause expensive damage to the equipment. The researchers still don’t fully understand how their solution works, so they will have to do more research before the reactors can go into production, but this is a great step forward.

Fusion reactors utilize the same nuclear reaction that occurs inside the sun to produce electricity. Fusion power is hailed as the next great solution to the energy crisis.
