What's a plasma TV? I guess I got behind in my keeping up with the latest gizmos. It sounds like a way to bring us closer to the peculiar Star Trek technology, with drive plasma being channeled all around the ship, so that every time the shields absorb too much energy and a relay blows -- computer consoles explode and singe crewmembers.
