Super Power Charger
These guys look legit. With a deep cycle battery and a swap to a smaller motor, any car could be eco and with the flip of a switch (one of those cool, red, James Bond, don't-touch-that-button looking ones), turn into a capable speedster.
This could be part of my Corsica project. I could swap to the little I-4 bugger with one of those. Too bad they cost a boatload.
They're working on a motorcycle version which could make for an interesting ecobike. Can anyone say literbike crushing 250?
