Have a Prius?  Wish it could get 100MPG in the city?  Maybe the Prius+ is for you.  It’s a PHEV, a plug-in electric hybrid, which lets you recharge the batteries from an outlet as well as from the car’s motor.

The details look a bit daunting, but the folks behind the project are demonstrating that they can convert a Prius in a weekend at this months Maker Faire in the Bay Area.
