Wind or tire powered car Printer Friendly Version
A car that is windpowered. A small wind turbin on the top or even underneath the car, maybe even in the front behind the grill. Cars are always producing wind. Maybe even a car that could be regenerated just by the spin of the tires. Of course their should be a battery that can be charged at home, or even by solar. this is such a great idea, and could easily be added on to cars.
Reward: getting the reward for free, or just let everyone know i was the first to have the idea

Cars that run on wind power Printer Friendly Version
I am not a scientist or even an inventor but I was thinking, wouldn't it be great if we could harness the wind that a vehicle creates to power it?
A completely renewable power source for motorized travel that doesn't cost a penny and would never run out. Of course the vehicle would need some kind of power source to start moving but if I am correct the power source could be recharged by the wind after the vehicle picked up speed. I believe the technology would be something similar to the wind turbines that currently capture wind energy used to supplement power consumption.
Reward: If a vehicle like this was every created, I would love to be one of the first owners, free of charge of course. Do you know how much money I would save in Gas?
