Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

I'm not sure what Butch Lafonte called his, but I remember a huge discussion where he (and others) were building a generator that had a rotor magnet that spun about a shaft, and the stator had an inner and outer part for directing flux as it spun.  The design eventually moved to a design that looks something like the attached gifs.

My questions are:

1)  Was there any reason the builders stopped working on this idea?
2)  The field produced by the induced current in the coils doesn't look like it'd interfere with the rotor action, what do you guys think?
3)  Would laminated silicon steel work for the stator, as I can't find ferrite?

The images below represent the same concept from two reference frames, the first is from the stator's view, and the second is from the rotor's view.  I really want to build this, and if I could get a ton of these on the same shaft, I'm hoping that a heavy flywheel will keep it running for a while, and only keep the flywheel going, since the shaft won't feel a 'load' I think...

The reason to stop working on this idea is only financial.

These are the times I wish I wasn't 21 and working at McDonald's, so I could afford these endeavors!  Haha.  Being in college is sucking my money away.  ;)

How true. I feel for you. Isn't there a way to get a scholarship or something? Sorry, I can't help at this time. I really wish I could.

Thanks for the support Omnibus, but unfortunately my major is Business Administration, even though science is my favorite thing to study in my free time.  I'm so glad for the internet to connect like-minded people for these projects and sharing ideas.  Since I don't know how to simulate Lenz Law in FEMM (I'm guessing you can't since it's not a dynamic calculator, only static problems), I put magnets where the 'opposing field' induced by the coils would be.  It doesn't seem to effect the rotor at all, and goes around it...

Anyone else building something like this?

I'm going to try to build this during summer.
