Raindrops keeps falling on my head...

Unlike Burt Bacharach and Hal David's classic, Raindrops (Butch Cassidy & The Sundance Kid) where Kathleen Ross rides a bike while the song lightly intones various ways to deal with the rain, "Researchers have recently developed a system that recovers the vibration energy from a piezoelectric structure impacted by a falling raindrop. The system works with raindrops ranging in diameter from 1 to 5 mm, and simulations show that it’s possible to recover up to 12 milliwatts from one of the larger “downpour” drops."

Forevermore my take on rain will be forever changed.
