Lightbulb remove the alternator and installing it on the front of the car

remove the alternator and installing it on the front of the car
sorry for the typo


i have been reading about the alternator removal and i have a few questions...

1. is i remove it and place it on the frost of my car with a fan that will allow it to spin as i travel down the road, is it going to raise my CD through the roof.

2. if i install a solar panel to the roof and make it flush to roof is it going to make that much of a difference. i would run it to the deep cell batteries along with the alternator in the front of the car.

the main thing that im asking is that if i put the alternator on the front of the car and allow the wind as i travel to spin it and give me some charge. is that going to kill me or save me FE

Well, I don't know if it'll kill you, but it will add aerodynamic drag, and possibly not work at all depending on the amount of force necessary to crank it at such a rate as to provide adequate power. Perhaps if it flew off and smashed through the windshield.

As for solar panels, I think the consensus is that it either won't provide enough power or isn't very high on the ROI scale (return on investment). Unless you can get some great solar panels for free or cheaper, and if that's the case please pass on the contact info!

Put a fan on the alternator and then make your car electric, with the motor powered by the alternator-fan. PERPETUAL MOTION MACHINE


The point is, every bit of energy you extract from the airflow around the car is energy the engine has to put back through the wheels, and then some.

Nice video... but what's the point of it? did they show any numbers? did they show that the props were even doing anything other then spining? how big of a prop ('fan") are you thinking? because... stollen from otherpower.com
wind velocity is in meters per second If we work the formula for a 5-foot diameter turbine in a 10 mph wind:

5 feet = 1.524 m swept area = pi * r2 = 1.8241m2 wind Speed = 10 mph = 4.4704 m/s So

Power available (Watts) = * 1.23 * 1.8241 * 4.47043

=
100.22 Watts

and just to run the ECU on my car is 80 watts, of course I drive alot of highway miles and according to the time log built in to my under hood tac, I've averaged about 37mpg, but others average much lower and you can fingure that anything at less then about 10mph is worthless.

Nice video. I like how the whirling blades of death are conveniently located in case of an accident.

If you think it'll work, test it out and report the numbers.
