Would this really work? (Cordless drill powered EV)

At the test, the V28 Bel Air hit 93.3 miles per hour, running the quarter in a very respectable 14.53 seconds.

Wow... that's about as fast as a "heavily modified" (read: riced out) Honda Civic...

It could be that much more efficient if they'd get rid of the 90* drive gear, even if it's not a gear and it's connected by a flexible driveshaft to go around the 90* bend, hysteresis (I believe the correct term) still drains part of the power necessary to turn the shaft, and to transfer power at a 90* angle.

It has previously been mentioned, cordless drills are very low power. A cordless drill will move a car, how long do you have to wait while it does so?

Enough gear reduction and the cordless drill will move a truck. Through a drivetrain horsepower is relatively constant disregarding losses. The force that moves a car is not horsepower, it is torque. Enough gear reduction and the cordless drill has sufficient torque, but it's power cannot be increased through gear reduction.

The video of the metro being moved by a cordelss drill is neat, but it sounded as if the drill was running at full speed. I think I can reach a destination by walking there faster, easier, and cheaper.

I'm too lazy right now look up the specifics, but lets assume the drill can produce 1/4 hp (optimistic) to move the average car at highway speeds this would require as many as 80 drill motors (20 hp).

The A123 batteries that a lot of EVers are experimenting with originally came from cordless tools. Rather than four cordless drill motors, four treadmill motors might fare better. (Still not great, but better.)

My daughters have a pink Barbie Corvette that I was too cheap to buy a 6 volt battery for. It's ok though, they have come to expect Daddy to be too cheap to get them anything. I'm thinking of stealing the motors in it to power my Geo Metro conversion. The girls are mad at me....
