seems like a nice idea.
But what is getting me suspicious is the long development time.
He admits that he uses electromagnets to stimulate the reaction, so it may well be that there is no power out. Maybe this is just another type of a motor.
(U could easy build that, by measuring if there is a magnet-roll in front of the electromagnet and then inducing a magnetic field.)
You would accelerate to the same amount.
7 volt and 600 mAmp are enough to produce that kind of constant speed at minimum firction you got here.
Careful this could be a scam, since he wants people to donate and lives in Thailand, where living costs are low.
