This radio runs on shower power

The H20 Power Radio screws into place between the taps and the hose, and then runs on power generated from water running through a micro turbine inside of it. It’s not clear whether or not it can be installed if your shower is the type where the taps and the head just stick out of the wall. But if it can, it can run even for a while when the shower is turned off, using integrated Ni-Mh rechargeable battery stores. Via gizmag.com.
