What about, putting wind turbines on the front of my car. Then on the one hour drive to work and then to my home, I juice up some batteries from the wind generated by me moving forward against the air.
Then when I get home I can power a radio or t.v. or something. would this save a few drops of oil?
I wouldn't be using any more gas than I already use getting to work each day.
P.S. I know this wouldn't work if you lived in L.A. with the gridlock and such. Also it's not a free energy device.

"I wouldn't be using any more gas than I already use getting to work each day." |

Ah, but you see, you would use more fuel. |
|
| |
It would make more sense if you had a turbine on your beanie. |
|

Partially baked anyhow. Energy conservationalists have been playing with wind-generators and solar powered cells on cars for a while now. |

Hybrid cars with regenerative braking systems. There's something that works. All that energy going up in heat at the stop light. |
|
| |
Simple thermo equation: learn it. Energy in - losses = energy out. Therefore energy in > energy out. Always and without exception. It makes the world go round. |
|

dag, the more times you convert energy sources, the more you end up losing. Also, I doubt that you'd win any gains; thousands of small powerplants are always less efficient than a few large ones. |

I don't think most of you thought this out. It would not take more fuel to push a car through a static medium if the turbines only took up the frontal area of the automobile that was already resisting the air flow. YES, if you stick your hand out of the window your will put more drag on the vehicle, but, if you put a fan in the radiator duct, it should not. |
|
| |
Got you there.
<Sits back, arms folded, waits for someone to propose putting the fan behind the car to use wind energy that would just be wasted anyway>. |

Dag, driving down the road today, I saw more suv's than hybrids. What Country can we get mor oil from I wonder. |

<politically incorrect>to paraphrase a friend's e-mail signature: Arguing on the internet is like running in the special olympics...even if you win, you're still retarded.</politically incorrect>
Ok, now that that's out of the way, any process designed to extract energy must have a source of energy to extract from. Even if the turbine takes up only the frontal area of the car, you'll be disturbing the airflow, and making it more difficult to push the car through the air. I've seen wind-tunnel proof of this: an aircraft with a stopped propeller (just stopped, not even feathered) will have much less drag than an aircraft with a windmilling propeller. (see link)
So yes, putting a turbine on the front of your car WILL increase drag. |

Instead of just quoting scripture, I will test this out. stay tuned. (politically incorrect. whats that?) |

Well just tested my theory. I ran around a high school track with a brick in my hand. Timed it, and wrote down how tired I was. Then did the same with a pinwheel attached to a generator. (same size and weight as the brick. Time was the same and I was just as tired as the original run. (and juiced up a aaa battery a little bit.) See testing out a theory is better than just repeating something someone else wrote in a book that cost way too much money at the local college because they changed one word in it. thank you, thank you. |
|

Can't argue with that.
In fact, I make it a point never to argue with people who run around tracks carrying bricks and generators with pinwheels. |
|

Perhaps you need to repeat your physics class: wind generators pushed by a car will add more need for the power of forward movement than they will generate. Now, put them on your car, but folded down to travel, then park in a windy area and tilt them up - that may work! |
