[RE-wrenches] gravity storage of excess PV generation

[Jerry Shafer]

Kirk, wrenches,
There are several gravity storage systems out there in the renewable energy
industry. I did water lift and drain back through lift pumps and
hydro-electric. No different than all storage systems, it's all about
capacity. Great talks
