Scientists at the University of Wisconsin-Madison claim to have found clean hydrogen fuel in the unholy mix of zinc oxide crystals, water and noise pollution. Researchers say that the process will not require any catalyst like oil, and will manage to be fairly efficient. Which makes it quite a winner, with noise pollution being quite ubiquitous in our world, using it to generate clean fuel sounds simply great.
The new type of zinc oxide crystals are submerged in water, and the mix is supposedly able to generate hydrogen by feeding off vibrations created by passing traffic and crashing waves. Researchers call this mechanism the piezoelectrochemical effect, wherein crystals develop areas with strong positive and negative charges due to the effect of vibrations, and this charge then breaks down the surrounding water molecules to produce hydrogen and oxygen.
The process is said to be 18% efficient, and once it is ready for commercial deployment, it could find application in a lot of things. After all, what it needs to work is just noise!
