Alternative Engine Equals Direct Current Here.

To start, a tantalyzing snippet;

Motor

Some people find it hard to imagine our car’s Lamborghini-beating acceleration comes from a motor about the size of a watermelon. And while most car engines have to be moved with winches or forklifts, ours weighs about 70 pounds — a strong person could carry it around in a backpack (although we don’t recommend it). Compare that to the mass of machinery under the hood of $300,000 supercars that still can’t accelerate as quickly as the Tesla Roadster.

But more important than the motor’s size or weight is its efficency. Without proper efficiency, a motor will convert electrical energy into heat instead of rotational energy. So we designed our motor to have efficiencies of 85 to 95 percent; this way the precious stored energy of the battery pack ends up propelling you down the road instead of just heating up the trunk.

Zero to sixty in four seconds. No blower, turbo, carb,pistons or gas.
It's all electric, and it is bad assed.

The Tesla Roadster.
The car is under production now and they are taking orders for the '08 model.
Two cents a mile to run ,by their estimates, it has revolutionary battery packs to store the electricity that it uses and can create its own by using regenerative braking.
This uses the electric motor to create electricity as a generator and greatly increases the distance you can go on a single charge.
For us older gearheads, remember the old days when cars still had generators instead of alternators? How did we test them?
By hooking up a battery to it and turning it into an electric motor.If it spun, it should generate when hooked up and driven by a belt.
Same thing here, just wayyyy modern electronics governing the input and out put.
