Wheel: easy. Use magnetic switches on the static portion (part that doesn't move). You can buy these switches at Radio Shack (house alarm switches). Then just rig up a simple SCR-based circuit. Since the switches are momentary (i.e. they only remain open while the magnet passes by), you will need to use the SCR's to do the actual switching of the circuit. The alarm switches are just used to keep from causing any physical drag, but you will want to find the smallest ones possible so you don't have alot of magnetic attraction to cause drag.

Self powering Magnet motors are not considered 'perpetual', apparently because magnets have a certain lifespan and need replacing or some crap like that (which would actually make PMM's nonexistent since EVERYTHING has a limited lifespan, be it ten years or a couple thousand trillion years).

Oh, and a solar panel would definitly kill the PMM, as it would be considered (I think) an external power source. If there is no light, it woun't start, right? BUT, I think if you have a rechargable battery that started it, remained in the system, and was recharged by the motion (converted static electricity?), then you would be OK. I have an idea for a true PMM that is purely mechanical... and if my calcs are correct, it will self start... I just gotta wait until my boss goes on vacation before I fire up the Gerber table router and make it

BTW, you can buy almost any type of cog, gear, pully, or whatnot that you need... just look online or go talk to a local machine shop and they can order you what you need. If you need parts made, talk to an 'all-around' sign shop, such as the one I work for. Some shops do injection molding, die-cutting, and have CNC machines (most likely some kind of CNC Table router such as the Gerber Dimension 200), and should be able to help you out with some of the parts.

Not sure about the AutoCad crap, myself... I can draw up perfectly good plans in Illustrator. AutoCad is a nightmare for ANYONE to work with, and mainly caters to plotter output. We get architectural drawings that are in AutoCad and we can't do a damned thing with them except convert them to a solid BMP or TIFF image and retrace them in Illustrator (sorry, engineers... I have alot of engineer friends who feel the same way as I do... including my boss.. it's just a fact... AutoCad sucks unless you are swapping files with other AutoCad users or outputting to a plotter).

*EDIT: Doh! Sry, XL5... we are talking about the same idea for the most part, lol... I think that using the mag-switches as an actuator and using the SCR's to actually do the switching (takes much less current to activate an SCR than a relay).

Hall effect switches are freaking expensive compared to the simpler alarm switches... I'm VERY familiar with them by means of aoutomotive technology (how do ya think the cars that still use a distributor system work most of the time?)... a thought just occurred to me. If cost is NOT a problem, you may actually want to look into some automotive ignition parts for hall-effect components. There are some decent kits to upgrade older point breaker distributor systems to hall-effect systems:

Auto Meter Electric Speedometer Senders
Hall Effect Crank Trigger

And here's a decent magnetic triggering system that you may be able to modify:
Holley Crank Trigger Kits (Magnetic)

Also, if you do a Google (screw Google... use something like Dogpile or Metacrawler, lol... be different!), you can find other hall-effect components and all the info you need.

Oddtodd, thanks for reminding me of that. There are also light activated hall-effect switches out there as well, but those suckers are expensive.

Basically, imho, I'd go with automotive parts (you could even concievably use used parts from a junkyard as long as you get all the components from the same types of vehicles (for compatibility).)
