  1. never could figure out why they would want the huge weight of the electrics up there. A vertical drive shaft might be slightly less efficient but would put the weight at the bottom of the tower.

  2. Why does it have to lock up when there's "too much wind"? Is there not a method for the turbine to simply generate more mechanical force in such an event? That idea in and of itself seems highly inefficient to me; the only reason I could see stopping a wind turbine would be if the energy grid or wherever the energy were being stored were close to reaching it's maximum limit. Apart from that why doesn't it just run 24/7?

  4. Wind Mills are a nightmare to keep them running with all the maintenance needed the cost value doesn't add up even with government money funding them. Not to mention the killing of over 100,000 birds a year. Scaring away animals and causing headaches to anyone near them. If there so great how come China doesn't have a bunch of these? If your near one of these like me I would take clean coal any day of the week.

  5. Hello, Jared Garrand,

    To make clear, my question, I make an exampel of my knowldge of solar power.
    Having seven solar panels of 42 Volts in serie, gives theoretical 294 Volts DC

    To connect on the grid / network, you need an invertor, to make it 240 / 250 Volts AC ( frekwentie, 50 Hz )

    My question is… do windmill systems work like this ??

    The Amps, x Voltage gives the Watts, that I know. And is depent on capacity of generator, windpower and
    Electricity demand.

    Regards, Gerard.

  6. Thank you for information and I like that video( but one doubt why 59.9% efficiency why efficiency encrusted plz explain

  7. which is better for the blades of the fan lightweight material or heavy weight material? does the weight of the fan blades affect the RPM?
