What I know for sure is the law of energy's conservation, so I won't buy that trick, and I won't waste more time on it.
Gosh, how po-faced you are! Why did you even bother commenting at all?
No-one is trying to convince anyone else that it is real. The ask is 'How does he fake it', and to me that's as interesting (because he is good at it) as it might be if it were real. I guess you're not a Penn & Teller fan.
You are right. My apologies.
Since you asked a direct question, I was at a beer, alone, in front of the screen, and opened blindly the first 3 topics. Usually, I wouldn't open free energy or debunking topics, but this time it just happened to be in the first 3 new posted. So I read it and I thought it's an RF trick, and the beer made me type an answer. Then, the trick was a little more complicated, so I typed a grumpy answer (another mistake).
It was not me, I swear, it was the beer. Beer is evil!

P.S.
And now, I am with another beer in front of the screen, breaking my promise to not type any more in this topic.
Well, since I already broke my promise, AFAIK the ball bearing on a rod engine is not fake.
