Perpetual Motion Delorean?

An anonymous reader writes "An electric-powered Delorean that can supposedly go "hundreds of miles" at speeds over 100MPH without stopping to recharge will be tested today beginning at 8am at the Nashville Superspeedway. They claim the vehicle uses 12 standard car batteries, so the invention appears to relate to recharging the batteries." I found a website offering current updates on the demonstration of this perpetual motion device: it appears they've suffered mechanical difficulties and cancelled the test.
