A guy I know from another forum built this thing, which he calls "Pocketchop". It was in response to some sort of challenge to build a chopper for $20 or something like that. It started as a 110cc Chinese pocketbike thing.
The builder, who asked to be identified as F_ck_ng Hell Fred, has this to say about the Pocketchop's ignition system:
"The Pocketchop's ignition system is powered by rust. There's a big round rusty thing that spins round and round. There's another rusty thing inside it what makes electricity for the coil. On the outside of the rusty spinning thing is another rusty bit, and it sees a lump of rust on the spinny thing go by, and when it does, it shoots pure rust along a wire to the ignitor box, where it's combined with cesium to form a spark."
