wind -> heat

  1. Seems like a good idea to me ... wind generator directly to electric
    heat (something like an Interthem unit with a water intermediate; none
    of that crappy short-wavelength heat) ... no storage except the building
    itself holding the heat.

    The theory is that when the wind is blowing is when you need extra heat.

    Whaddya think?

    Sure. Turn one side of a torque converter from an automatic transmission,
    inside a water bath. The other side of the torque converter is anchored.
    This will expend the energy generated by your turbine, and turn it into
    heat energy in the water bath. Move the warm water to where you want it.

    Or, use an electric wind turbine, put a resistive load on the output.
    Power resistors are pretty cheap and pretty effective (and small). Use
    this heat as appropriate.

    Take the unregulated DC out from the wind generator, and feed it to
    a DC water heater (with higher voltage rating than your turbine can
    generate). Use as appropriate.

    If you don't need nice clean 60Hz sine wave from a wind system, there's lots
    of ways to get heat directly from it. No point in losing some of that
    energy out in the power shed converting it to one thing, only to use it
    for heat. The ugliest buzzy modified-square wave in the world will
    generate heat when you feed it to a resistive device.

  3. turn a large volume of wind into a smaller volume at higher pressure- it has
    to give up thermal energy. Ideally with as few moving parts as possible.
    Most mechanical energy conversion sucks in efficiency.
    How bout' it, home power enthusiasts?
