Storing Solar Power on my ROOF!!!

Quint BUILDs tests a rooftop water storage setup in which solar power pumps water up to the roof and a turbine generates power later. He works through the numbers to show how much energy it actually stores.
HN commenters cite it as an entertaining reality check on home gravity storage, showing the yield is tiny compared to household needs.
