I don't know who he is, or what he's inventing. I like all the little gauges.
I've been informed by blogist Mike Overall that he is in fact Nikola Tesla, and he's demonstrating the world's first ever radio. Mike says 'In fact, the band Tesla was named after him and their first album was "The Great Radio Controversy" after the patent wars between him and Thomas Edison. He was a man out of time, man out of time...'
Thanks indeed Mike!
