Inspired by other Endless Gears, I started working on my own. 

A 9V block battery is hidden inside. This runs a small motor which drives the gears. 

The motor with the gearbox linked in the description turns the first wheel 1 time in 5 seconds. The first wheel therefore turns approx 6.3 million times a year. It takes 274877996844 revolutions of the first gear for the rear gear to have turned once. This corresponds to approx 43582 years. The rear gearwheel would move approximately 0.008° per year.

Parts needed:

Theoretically, everything is possible without soldering. The magnets clamp the cable - so they retain their full force. 
Pay attention to the alignment so that the motor housing also pulls on the gear housing.
