Have you ever think [sic] that any slightest vibration around us like the vibration due to noise and other sounds is also an energy that we can use? That is what has been proved by materials scientists at the University of Wisconsin-Madison led by Huifang Xu, UW-Madison geologist and crystal specialist. They have managed to find a process called piezoelectrochemical (PZEC) effect that can turn water into hydrogen fuel.
Actual basis of this process is Piezoelectric effect. It’s the ability of some materials such as crystals, certain ceramics, bone to produce electricity while undergoing mechanical stress. Piezoelectric crystals are quite tiny and can enough to produce a voltage. The nanocrystals of zinc oxide and barium titanate are put into water. When these crystals received ultrasonic vibrations, the nanofibers flexed and catalyzed a chemical reaction and will resulted in splitting the water molecules into hydrogen and oxygen.
Piezoelectric crystals itself are actually able to produce an electrical energy, but scientists are more interested to use it to produce hydrogen fuel. They reasoned that the hydrogen fuel is more stable than the electric charge, more easy to storage, and would not lose potency over time…
