Wind powered car possibility

  1. Mar 29, 2012 #1
    Hey community! First I'd like to say that this is just a concept. There are probably many faults in this idea since I'm only 16.

    Basically, I was wondering if it would be possible for a car that runs purely off of wind/electricity. My concept would completely eliminate the need for gas, recharging, or precious water sources.

    The concept is relatively simple on the surface. The car initially starts similarly to an electric car. Once the car is in motion, the car begins to take air in from the front. The wind is ran through some type of self propelled wind turbine system located near the front. The front turbines would compress the air to a high speed. Once the air is compressed, the air would spin an internal turbine(s) (which could be linked up to the front turbines to turn them). The internal turbine(s) would act like a generator producing electricity for the car and recharging the battery. Theoretically this car would run itself at certain speeds.

    Here are some of the questions I would like answered.
    1) What is your opinion on this idea?
    2) How efficient would a wind generator be? If it's bad, what could be an alternate solution?
    3) Could air be compressed enough and made to move at high speeds (200+ mph)?

    These are the main questions, but I'll probably ask more later. Thanks for the help! :smile:

    Welcome to the PF.

    No, sorry. What you are describing is a Perpetual Motion Machine (PMM) or Free Energy setup, both of which are impossible because of basic physics. It's good to ask questions, but in this case, conservation of energy makes it impossible.

    I'm going to lock this thread (PMMs and Free Energy are on the Banned Topics list at the Rules link at the top of the page). But check back in a bit, because I'll post a link to a webpage that will help you to understand why all PMMs cannot work.

    EDIT -- Here are some good links that you can read through to help you understand:
