cap charging batteries

  1. I want to have a small wind turbine on my roof.

    the wind here is pretty mellow but steady.

    I want to store the energy in a capacitor and when it's full let it loose
    into the batteries with higher amps and volts.

    like a beam robot

    it'd charge intermittently but at a useful level of amperage and voltage.

    any plans for such a thing that anyone here knows of?
    perhaps a kit?

    Why?
    For simply charging them, this is worse than constant current.

  3. I don't expect very much output

    doesn't the voltage going in have to be greater than the voltage of the
    battery?

    Yes.
    But if you have some means to charge the capacitor to a higher voltage
    before discharging it into the battery, you'r almost always better just
    using it to charge the battery.
