Making a Homopolar Generator Overunity

Yes that is precisely what I was trying to describe. It is good to know it is open source.

I posted preliminary maths in 'Kinetic Hiker Backpack becomes solenoid array'.

I hope we are not too off topic in relation to this great thread about Michael Faraday's homopolar generator, which I really enjoyed reading.

Now when you spin the copper disk, the permanent magnet will generate some current in the disk that can be siphoned off. Suppose some of this current is diverted into the coil that forms the electro-magnet? This will then generate additional magnetic flux and when that combines with the permanent magnet's flux, you get an exponential boost in flux strength when it passes thru the copper disk. This will generate more power. So if the permanent magnet were to generate enough current on it's own to create an electro-magnet with the same field strength as the permanent magnet, the combined field strength would 4 times as much. That means, all other things being equal, that the power generated would realize an incremental gain, which is 3 times as much as the original current, and which can be used for other things including running the motor that spins the copper disk. In theory it should be able to handle the disk motor and have extra power left over.

Tesla did mention the use of spiral spokes to direct the eddy currents in a way to enhance the overall magnetic field. In my experiment, instead of using spiral spokes, I used a 3-turn coil surrounding the circumference of the cylindrical magnet. The magnet was glued to the copper disk.  For some unknown reasons, I ended up with some unexpected results: I got an AC output in addition to the DC output. The DC output is too small to be usable, but the AC voltage is much higher than the DC voltage.

Surely you've connected the coil in the opposite direction ..
try switching the wires of the coil ..
