Electricity from Rain? Can’t Believe It?

Well, it’s real.  It’s call piezoelectricity.

It’s the phenomenon where certain materials generate an electric charge when subjected to mechanical stress.  Now, of course, the stress caused by falling raindrops is extremely small, so we’re talking about amounts of electrical energy that are of very little practical consequence when significant amounts of power are required.

But consider the microphone, whose duty is to turn sound vibrations into a few milliwatts.  That’s where this excels, and it’s been in use for many decades.

So, is the claim here a lie?  No.  Is it misleading?  Of course.
