With due respect to the November 14th opinions Mr. Eric Brown and those of like mind express over the virtues of pumped energy storage as a means to reduce CO2 emissions, I believe we are in need of a 'reality check' on the basis of both physics and economics.
Pumping water uphill and then extracting energy from it during downflow results in an approximate 30% energy loss (and financial loss) from the initial energy investment. These losses are in the form of waste heat which will find its way into our atmosphere. (Something we need less of.) Consider also the significant volumes of diesel fuel required to power equipment needed to construct this facility.
