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.
