an efficient way to store massive amounts of electrical energy That would only be needed if wind and solar were at some points providing more electricity than the nation as a whole was using. Otherwise, you can just adjust power plants that use other sources. There is no real need to store more than a few minutes of electricity to facilitate changeovers. TP

Some ideas I've seen proposed are using electrical energy compressing air when we had more energy than demand, then using it to drive turbines when the energy was needed. As an engineer, I just LOVE efficiency! What kind of efficiency does a system like that have? When I was a teenager, i went to a field trip to a power plant in Slovakia, where they have 2 lakes connected, one at high altitude, another at low altitude, and what they do all day is either pump the water up, or generate power on the way down, based on the power demand. Great system, if you asked me, but something extremely large would need to be built in order to smooth out the peaks and valleys of demand and supply by sources such as wind and solar. Joe
