Is Germany Celebrating Halloween?

BOOOOOO. Sounds great for Halloween! The lights come up for a moment — then down — and then it’s totally dark! Spooky, albeit a bit dangerous for pedestrians.

Hugely expensive though, probably 500 – 1000 times conventional approaches.

Actually, it’s worse, now that I look at it more closely.  The turbines are encased in columns that block the air flow.  You’ll get just as much wind in your basement.
