Potential new ideas: self powered switches and transmitters

While researching stuff for my fyp, I came across this link:

EnOcean Self-powered RF Modules - Ad Hoc Electronics

I only know very rudimentary forms of self powered FM receivers (powered by actual EM waves), but it's interesting to see commercialized forms of these kind of transmitters.

The wireless switch is a good example. When you press the button, it moves a magnet past a coil and generates enough energy to transmit a wireless signal. It's such a simple concept, I wonder why we don't see more of this?

And the implications of those solar RF transmitters than can store enough energy to work for several days in darkness is quite a neat thing. A lot of potential there.

I'm pretty sure a lot of project ideas can come out of integrating these. In addition, why not try making better versions of those self powered switches and transmitters? *grin*
