    I did several test. None of which yielded the results in this video. I doubt it works. My batteries overheated. I changed polarity of the magnets, did multiple flat surfaces all to no avail . I have the exact magnets used by the author. I posted to my YouTube as well. I do have an electronics eng degree so I know a thing or two about this. Physics in my universe are apparently different .

    this my last experiment; I Achieved no discernable movement from any form of energy other than outside forces acting on the battery/ magnet device. I have access to oscilloscopes, digital and analog , voltmeters , temp meters and other test instruments I have in my home electronics lab but a simple temperature probe shows this to be a dead short as the temp exceeded the scale of my probe there.

    my video post didn't take, not sure why. So this is what is going on: This can not work. You are shorting across positive and negative leads of the battery. Motors require brushes, stator and rotor , the intermittent current connection in the coils in rotor creates a magnetic field that is affected by the permanent magnets on the outer housing ( assuming the simplest motor design ) if you change the polarity the motor will spin the opposit direction . Think about North and South ends of a magnet. If I take two magnets and put south to south what happens? Consider the law of charges , opposites attract , take a comb, swipe it through your hair a few times , cut up some pieces of paper in to tiny pieces and hold the comb close to those bits of paper. See what happens ? ...this video rem...see more »my video post didn't take, not sure why. So this is what is going on: This can not work.

Sorry if I bursted the bubble here.

    this is a Homopolar motor, and there is a specific reason it works. Google it.

    The will not work, why? The answer is that you are shorting across the positive and negative lead of a direct current storage battery. A motor has a stator and a rotor. It has brushes that make intermittent contact with the current source, and permanent magnets (assuming the simplest motor example) I have watched this video a lot and sorry , this will not work . I will back up my statement with the fact I have an electronics engineering degree( amongst other fields of study) I know this will not work but I posted video of my own version of this and it worked not. This is an example of a dead short, not a motor. ..
