Where will all the water come from?
pstarr wrote:You also need a second reservoir at the bottom of the sluice gate. Equal in size (minus evaporation) to the upper reservoir.
All you need is enough water to run the turbines for 12 hours.
Then when the sun comes up the VERY SAME water that just came through the turbines gets pumped back up using excess PV (or whatever) power.

dissident wrote:The 12 hour claim is utter BS. You can only supply some small fraction of Las Vegas electrical demand with this amount of turbine operation.
Pops wrote:Of course there will be a loss, just as there is a loss in all systems. Loss is a given in all energy systems, our overall system loses 60% and still going.
Plantagenet wrote:So if takes more energy to pump the water back up then you get from running the water down through the turbines, why not use that energy directly to power LA instead of wasting some of it pumping the water back up hill and using the energy from water going through the turbines to power LA. Why not just skip all the pumping and turbine turning and just use whatever energy source is doing all of that work?
