Obsessed with MINI Coopers but also like the idea of zero-emission electric vehicles? Have your car and drive it too: a company called Hybrid Technologies guts cars such as the MINI, smart fortwo, and PT Cruiser, and replaces their gas tanks with an electric motor and a stack of lithium batteries. Convinced? Starting in 2008, you’ll be able to buy your electric MINI at Wal-Mart — for a mere $65,000.
