-> Not so great with wind-generated energy is the fact that you need a
-> battery bank, and batteries are expensive.
-> So why not store the energy as gravitational potential energy?
-> E.g. make the generated energy lift a large weight, controlled in such
-> a way that it falls when you need it to, yielding just the amount of
-> electrical power you need?
-> ??
-> Parts would need replacing far less often than batteries.
-> John
It's already done in many places, pumping water uphill when surplus
power is available, and letting it run down through turbines when extra
power is needed.
