One Fusion Reactor Problem Down, Only A Million Or So Left
I keed, I keed. New Scientist has an article about researchers who have discovered a way of keeping fusing plasma from bursting out and damaging the reactor walls.
Researchers at General Atomics, a company based in San Diego, California, US, discovered a simple way to prevent ELMs from occurring. By using a separate magnetic coil to induce small perturbations in the reactor's main magnetic field, they found they could bleed off enough of the plasma particles to prevent the ELMs from bursting out. The solution was tested at an experimental reactor based in San Diego called the DIII-D National Fusion Facility.Now if they could only get to that pesky breakeven point...
