Novel Material generates electricity from moisture differential

In this article in New Scientist they report: ‘Electricity has been squeezed from a damp surface for the first time, thanks to a polymer film that curls up and moves – a bit like an artificial muscle – when exposed to moisture’

In a previous post I referred to a solar chimney concept that essentially is a synthetic, inside out, tree. Key to my concept is a energy generating ‘leaf’ that uses generates electricity from the mechanical energy involved in flipping between two physical state configurations. As air flows by the bistable ‘leaf’ flips back and forth and with each flip a small amount of electrical energy is derived.

As I was reading the New Scientist article above I was reminded of this concept since the polymer mentioned in the article is performing a similar bistable shape flip-flop and generating electricity as it does so … not that far off my leaf requirements except for the fact it requires a surface and moisture.

But … it gives me hope …

Most things I do involve computers. Nowadays that sounds stupid to hear because everyone uses computers. Except I was saying that before the IBM PC came on the scene. (hint: my first programs were entered on punch cards in an IBM-29) Now I mostly use them. Mostly to provide a community service in my small town. Because I could when it was asked and still can. And I'm a wannabe writer. Various books in various states of incompleteness. A few short stories. Might do more of that.
