Ryan, Moon is a very respected person, i'd appologise in your place. I have a hint that either you are not understanding something, or you are not explaining your thoughts in a manner that we may have a hint as to what the hell you are actually proposing.

Here is what we've been trying to explain to you

start with your axle regen:

We understand that you are basically saying to put magnets around the axles and coils around axles, and any time you are moving, you are generating back some power. This is true and this will work, and if we were in near weightlessness this may even have a decent degree of efficiency, like close to 80%, problem is that in order to facilitate any amount of power generation from motion, you need 2 things. One, you need magnets, two you need a coil. it matters little which one spins around what, rare earth magnets can be cast into the axle, this however already makes the axle heaver, and bulkier, then you need to add copper wound coils around the axles to generate power, and i dunno if you've ever played with any large electric motors, but they are heavy, and thus the design, unless you can come up with efficiency of over 1, will increase the total consumption of fuel in the end.

regeneration using air:

this one, so far, just sounds like you know not the first thing about car design, airodynamics, drag coefficients, oh and wind mills. problem is, that in order to regenerate power from wind, you need a device that will create wind resistence, and utilize that resitance to turn a motor. This creates 2 issues, one, you still have to have a motor to generate power, and two, you may be totally messing up the airodynamic factors of the vehicle by that decreasing fuel efficiency even more.

don't believe me? go down the road, open up your window, and stick out your hand, palm paralell to the ground.... this is the car body moving through the air at whatever speed you are going at. Now lets increase your hand's aerodynamic drag coefficient, by having to come up with a way to mount a turbine on the car. For you its simple, turn your palm till its perpendicular to the ground. Notice more resistance back? In a car, the motor has to fight that, the more resistance, the less efficient the vehicle...

Finally to wind mills. They are a stationary object positioned in places where air temp differences move large mass of gases, more or less, constantly. The pitch on the blade alows the air to flow around the blade in such a way that it constantly creates a low pressure terminal on the back side of the blade thus spinning the prop one way. What you dont see/feel is that there is energy that gets exerted on the wind mill, but because they are teathered to the ground, the construction of the structure pipes that pressure caused by wind and not used for spinning the blades, into the ground (which is obviously heavier and thus is less likely to move with that tiny amount of push....)


I'm tired, later
