Alohaspirit,
Sorry about being off topic ......
Clev,
You basically described an SAE Formula Hybrid -
Formula Hybrid
Most of the SAE Formula Hybrids built use a 250cc 4-stroke driving an Etek for charging. Both Series and Parallel Hybrid systems are used. Some of the teams are using SuperCaps in series with the battery packs to balance the discharge load under acceleration, and to capture regenerative braking energy.
