Storing wind-generated energy as gravitational potential energy?

-> 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.

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.
