Wow, capacitive muscles. A friend of mine invented that in about 1984. The problem is that it's so very inefficient compared to motors, unless you recover the 1/2 CV**2 on the return stroke.

Not to mention that a friend of mine did his Bachelor's Thesis (1963) at MIT under Dr. Anwar Bose's tutelage on that form of speaker.

Bose's company is ruthless. Probably put Polypower out of business in a few weeks ;-)

Why harvest picowatts when lithium batteries work so well?

Green jobs, of course!

Half a kilowatt-hour to make a picowatt harvester--everyone wins.

Be an interesting complement for those electrostatic sticky-pads.

All it needs is vacuum tubes to switch the voltage! :-)

Hum, is this Kynar again, or have they improved it? Of course kynar was priced so expensive you couldn't prototype it, I think the sales department didn't WANT to sell their product.

Somebody do the reading exercise and tell me if its poled PVDF again, or something better.

Boxes full of speakers lining all our airport runways, running in reverse...

I have no doubt we could get some science writers to take that seriously.
