Interesting application of this is with the Steenbras power project, near
Cape Town, South Africa, where the water from a dam in the mountains powers
hydro-electric generators on its way to a reservoir lower down. In off-peak
periods, the generators run in reverse to pump the water back to the higher
dam.
