That's cool, but it's dark for more than an hour.

A German power company is looking at using salt caverns currently used to store natural gas into a gigantic flow battery that could power the entire city of Berlin for an hour.

Which, you know, handily illustrates the problems of trying to scale up the sort of solar/wind/battery setup that's ideal for running an off-grid hermitage to powering an entire industrial society.
