Sorry, that makes no sense to me. Care to elaborate? Maybe pics?
Here is the one we use a lot at work, crazy handy thing to have on a truck. You can see how they look though...


Ok Sheldon, lets just agree to disagree. I understand perpetual motion and believe in a TEMPORARY perpetual motion. A video on youtube claims the wheel they made was spinning for a month before he physically stopped it. I'd say anything that can spin for a month with no help is perpetual. I understand that magnets wear (after a LONG time), bearings go bad (after a long time) and parts wear (after a long time as well). Everything breaks down with movement and time so that's a given. So I will stick with the temporary perpetual motion. There are a lot of good examples like Aldo Costa's wheel and the gravity powered generators and Gravia lamps. Check those out.
They need to be manually started and basically slowly dispense that energy over time. Kinda like a kid on a snow sled. Instead of lifting weights to slowly fall and power an LED light up you walk up a hill.
I am pretty sure they make flashlights you shake and something moves inside to charge a battery which is similar to your Gravia lamp theory.
The electric spare winch is a cool idea but...
What if after 20 years of non use you finally have a flat after a 12 hr shift, hit the button, and the motor dont work....
Simple mechanical objects are the most reliable, espicially the little bit a spare gets dropped.
Personally, i throw mine in the bed
They all screw up. The cables break, the winch part messes up... underslung spares always have been and always will be a PITA.
IMO ditch the cable altogether and come up with something better.
After 20 years of non use who wants to bet the spare is flat anyway?
