Fuuuu*k that's annoying.
I like looking at wacky science scams, since they usually include *some* kind of technical spiel, which can be amusing.
But that video is 102% pure advertising, with no tech content at all. Except for being an insult to Tesla by trying to leverage off his greatness, which makes it even more insufferable.
There isn't even a progress bar on the video player, so you have no idea how much longer that infuriating crap will go on for. Or is it perpetual?
So that was many minutes completely wasted.
Anyway, any 'free energy' scheme that promised to "reduce your power bill by x percent" is stupid. If a 'free power system worked, the only future relations users would have with power companies, would be legal issues due to having cut the cables to the street, and refusing to pay anything at all. Which I am sure would turn out to be illegal in some way, such as urban building codes requiring a grid electricity supply, without which buildings would be condemned as unfit for habitation.
