Germany is building the world’s first wind turbines with built-in hydroelectric batteries

Wind blows. Water falls. But for the first time, one is now powering the other. Engineers in Germany are storing water for hydroelectricity inside wind turbines allowing the towers act like massive batteries once the wind stops blowing. It’s the first major example of the two technologies being physically integrated to supply reliable renewable energy.

I think there’s a bit of water in and around some of those places that voted for Trump. Maybe a better use of it than for water cannons to spray on protesters in sub-zero weather?
