  •  pumped hydro is off the shelf tech (0+ / 0-)

    in fact old school, we built about 22 gigs of pumped hydro by 1996 IIRC. Though mostly matched to coal plants.

      excess capacity from what I've read, so might as well use it. I'm sure that smaller-scale versions can be built that would be cost-effective.

      •  Yes, small and mid size hydro (1+ / 0-)

        were hardly exploited in the big dam building years, so lots can be added to capacity.

        •  A while ago I had this hairbrained idea (1+ / 0-)

          about using excess electricity to power desalination plants on the pacific coast, then pump the much-needed water to the Central Valley and over or through the Sierra Nevadas for irrigation and local water use, using the downflow of the water to power turbines to recapture some of the electricity used to pump them up. It would probably be too inefficient to be practical, but who knows.

            I've been following Polywell fusion for a few years. Small compact fusion, no waste, little radioactivity. 1000mw plant 35x35x35 building.

            SO build Polywell plants on the west coast to desalinate seawater, this provides coastal agriculture water, cities and towns drinking water, so the rivers arent pumped dry. Pump water inland to alleviate water use pressure also.

            Yeah pumping water uphill is very energy intensive, friction loss by itself is a killer. But yeah with spillover power it could be done.
