Electric cars are infamous for their range. True, most daily commutes won't take more than 40 miles. However, we'd still like to be able to go on cross-country road trips without having to stop every hundred miles to plug in the damn car. EMAV, a Warakusa, IN company dedicated to electric cars, have designed a perfect solution: a mini-trailer that doubles as a mobile recharging platform.
The Pru is not so much a trailer as it is a hybrid charging convoy hitched to your car. Its wheels are powered by a 240v internal motor that matches its speed with your car's. While you're driving, the 750-cc diesel generator and lithium ion batteries keep your EV fully charged; you'll get up to 700 miles on 6 gallons of gas.
EMAV founder Will Cashen hopes to release the Pru on first quarter of 2011, at a street price of $15,000. Let's wait for him to get it out of the concept phase first.
