The article doesn't have any details, but I assume he is trying to demonstrate an effect of electric field inside a Faraday cage (which should isolate the electric field).
I would suspect that his Faraday cage is not perfect, especially since there is a laser beam going through. (The only perfect Faraday cage might be a completely closed box made out of superconductor.)
Still, I wish him luck. Maybe he'll find something new.
It would be nice if the video showed the laser experiment described in the article. I am trying to visualize it, but having difficulty.
I like my stationary corvette too. I'm too old to warp.
