In a vacuum, a conventional circuit breaker -- which measures heat across a load -- doesn't work, because there, there's less or no atmosphere there to draw the heat off, so a conventional circuit breaker would trip.

"When you slide that door open, all of the electronics are exposed to the near-vacuum, so we had to develop a solid-state breaker that was monitoring actual loads across that circuit, " Thompson said.
