Temat: H2O Power radio runs on water from the shower
Power is generated by the force of the running water, which flows through the otherwise-waterproof radio and spins a micro turbine inside of it. You can even keep listening to it while you're toweling off, without leaving the shower going, as an integrated Ni-Mh rechargeable battery stores and releases excess power generated by the water.
