if you want a novelty device build the SSG and tweak that to get some power out of it to charge a battery. At least you will get something for your troubles while you can learn more about the electronics involved. The SSG is similar to what you are trying to do and there are already several working models using fan motors and CD drives etc that speed up to staggering speeds with hardly any input current. You will find the use of fets work quite different to what we are doing here as they are capturing devices rather than catalyst in the TPU. Although the TPU theory is sturdy we have yet to discover how the make an open loop design and stop the normal electron flow in the exciter.

I realise you are not aiming at a mechanical version, however I like it for its simplicity, I understand the phase problem and do think there are a number of simple work arounds. Ideally a completely solid state one would be great, but I don't need ideal and since my electronics skills are basic it would be more difficult to construct for me. I want one you can construct from easily sourced components that could be built where only they are available. I am sure this sounds really sad, but I also like to see things working, so I would probably stick a few coloured leds on the rotor 

I had thought of hybrids and have a few ideas.

Apart from the phase problem, is there anything wrong with the basic idea?

Absolutely not.

I am looking for total durability though from my view.
Think about this. They need water wells in some of the poorest parts in Africa. MAF (Mission Aviation Fellowship) drills them. The next step is automatic pumping for irrigation, electrical production and cooling. No moving parts. Very remote installations. Very light transport requirements are needed because their goal is drilling equipment and medical supplies, which must be kept cool.

Everything is valid. What ever it takes to get the technology out there.

--giantkiller. More goals than time.

gk if you have other fets handy then use them nothing too critical here and should work just as well. If you look at SM's PCB on the smallest coil its tiny even if packed full of surface mount which i very much doubt the power requirements must still be very small. Whatever the class A amp to the size your building should be enough to power a 7kw 4ft diameter coil

@ bolt and just a question but are you left handed as well?

Totally with you on that about Africa etc.  I understand for the application you have in mind mechanical is not good for reliability. But for applications where people are around and device reliability is not so critical, i.e. for powering an old TV, then a device which is simpler to construct because it is partially mechanical has its uses too.

SInce you are happy that my theory is sound, I will continue to work on my design, I hope you don't mind but I will ask the odd question or for advice now and then. I will stay on this thread unless anyone objects, because a) it is my second home now. b) you guys are on it c) I follow your work even though your electronics is getting way beyond my ability. 

I realise my device is not solid-state, but I think there is much cross-over of ideas and theories. I will not clutter up the forum with too much mechanical stuff, I promise.
