A second "Steam" revolution?

"Jan. 10, 2013 — MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapor.

The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up and down. Harnessing this continuous motion could drive robotic limbs or generate enough electricity to power micro- and nanoelectronic devices, such as environmental sensors."

This is another pretty freaking cool idea. A material than can organically harvest energy from nothing but Water Vapor. This could allow a whole new era of powering devices, much like Steam Power revolutionized industrialization. This could be a very cheap, clean, and effective way of powering just about anything. Keep your eyes to the future folks, cause there is certainly a lot to be excited for.
