I found more and the people who made this device (first video) are completely destroyed on all the forums etc...
I'm not so sure this is scam, maybe it is a threat.
I will look into this because nobody took the time to really investigate and build something.
They use materials I've never seen before in relation to magnet motors.
To make it look like real and special?
Check the attachment for the plans who were online somewhere.
