The “Air Car” can’t sustain itself because perpetual motion is impossible?

Max asked:


but why can’t there be an alternator run by the engine that will re-charge a battery that runs a small compressor to slowly re-charge the tanks overnight? Why couldn’t a fan mounted somewhere on the car use wind energy from the days driving to charge the battery? There must be some way to create enough energy to run a smal air compressor, at least to improve efficiency. What would stand in the way of making that work?

    Why not? If wind turbines can create enough energy to power a whole town, why not a smaller version for a car?

    Hi, maybe the weight of batteries is too much. The air car is small and lightweight…..check out that new model from that guy in Russia…..his has a glider parachute attached to it.

    What stands in the way are the laws of thermodynamics. Take it up with Newton.
    The wind thing would work, if a wind turbine wasn’t so expensive to set up to begin with.
