The discovery -- which, unexpectedly, relies on heat-generating plasma -- is not meant for weaponry, however. Mechanical and aerospace engineering professor Patrick Hopkins wants to create on-demand surface cooling for electronics inside spacecraft and high-altitude jets.
"That's the primary problem right now," Hopkins said. "A lot of electronics on board heat up, but they have no way to cool down."
