can store electricity
......................................................................................................................................................................................
(one of) the problems with wind turbines is that the wind doesn't cooperate. Sometimes electricity is needed when the wind doesn't blow. Sometimes the wind blows when electricity isn't needed. Sometimes the wind blows TOO MUCH.
Some type of 'buffer' is needed to balance the supply/demand cycle.
This will do that.
Never mind how efficient it is. That doesn't matter. Either the 'off time' electricity from the wind turbines is stored....or it's wasted. Nice wind turbine you got there...shame to waste 80% of it's potential. Yup...windfarms only operate at about 20%.
Shame that.
This could solve that problem.
