Gallery: New Piezo Crystals Harness Sound Waves to Generate Hydrogen Fu...

 

It sounds like a strange combination: zinc oxide crystals, water, and noise pollution. But scientists at the University of Wisconsin-Madison have discovered that the mix can efficiently produce hydrogen without the need for a dirty catalyst like oil. By submerging a new type of zinc oxide crystal in water, the scientists claim to be able to harvest hydrogen using vibrations from passing traffic and crashing waves.

    the method i use uses 43,000 cps ultrasound and zinc oxide mesoglass. the 43,000 cps is close to the keely water frequency and the mesoglass allows for the formation of anderson localizations.

    Why not generate sound by dropping steel balls onto a surface that will vibrate? Gravity is free. Someone would need to raise the balls to drop; like a grandfather clock that needs winding once each week maybe small huan effort can be turned into a more valuable form of energy.

    […] relax and enjoy the sounds of the sea. The yacht’s roof is composed of two sections made from piezoelectric material that retract when the weather is at its finest, treating passengers to views of the surrounding […]

    I agree freezway. but the third question is, how long will it take to hit the market and I am guessing its going to be a long long time

    2 questions
    1. How much does it cost
    2. how much juice can it produce

    This exact thing has been on my mind lately…couldn’t the energy of sound be captured and converted into other forms of energy? If this material was in the muffler, for example…it could provide an alternative to traditional battery power.

    This is quite interesting. Sounds like it has potential.
