Finaly someone did it..

      I'm going to try a hybrid dc motor and unipolar generator with as much of bruce de palma's insites as possible. correct me if im wrong but I think the unipolar cannot run itslef with its own power because the effect is not receprocative which means ill need to incorporate a dc motor on the shaft to use at least part of the generated powere. will definately be a pulsed dc motor also. any input from you guys would be greatly appreciated. Also is there a reason most people use copper disks instead of aluminum, like an advantage I dont know about?

Faraday disc generators/motors (the homopolar motor) suffer from back EMF/back torque just like all the others.  Build one, short the leads, and try to turn it, you will feel a force opposing you.  Its because if you apply current to a homopolar machine, it will spin.  But the spin direction is such that it makes the machine build a voltage that cancels out the applied source (well nearly cancels it out - under no load conditions).  You place a load on the machine, you get a slip and the battery must constantly input energy.

The same goes for generator mode.  You spin the homopolar machine and a voltage is produced.  Connecting it to a load makes current flow through the machine in such a way that the flowing current creates a force that opposes your applied force - making it hard to spin.

I will say that Faraday disc machines are really neat, they almost have a mystical feel to them.  I had an idea for a hybrid Faraday disc/synchronous machine mix but its very complicated to build (getting the positioning just right and establishing good contacts is an absolute nightmare!)  I started to build it but stopped.  I'd disclose it but I just don't feel comfortable with disclosing my ideas publicly.  Its nice giving to the world but the world won't give back, and I have a family to feed!

Water falls from the sky, yet you still have to pay the water company....

Even if there was "free" energy" the government would just slap some sort of Energy tax on it and then have inspectors to check on you etc...

When big machine like factory made then why small wheel fluttering? Where he made this monstrum - in this dark camarilla? OK but then why not  to install this only visible moving part correctly.
Not ably?
