Yes, that’s pretty much correct what you have just read. You can now play your favorite tune simply by watering the speakers, just like you water the plants. Wave Tower speaker from Stefanie Koehler is an audio gadget that runs on water. Water creates a small chemical reaction in the fuel cell proving a stable current of electricity to power the speaker, and that too at a nominal cost. It can also be used to play the iPods as well. It will surely help to reduce the electricity consumption, thereby lending a helping hand in saving the motherly planet.
