In what seems to be a recent trend for my posts about going green, I continue today with what I see as a really cool and hugely potential offering in the area of green energy. Not many people have heard of or know how to say or spell piezoelectric crystals, yet almost everyone at one point in time have held a Piezoelectric Crystal or PE crystal. Before I let you know what it is you’ve held I want to share a little about the PE crystal and some of its potential.
In basic terms, a PE crystal is material that when it is pressed, squeezed, or vibrated it generates a small voltage of electricity. Alone this isn’t remotely enough to generate any kind of sustainable power, but when you put them together in a collaborative environment then the possibilities start to take form. Think about the vibration that cars make as they drive across a highway. What if we put PE crystals lined underneath the road to collect all those vibrations and turn it into electricity to power the street lamps and signs. You’d still want to have a fail over form of energy to provide electricity for the roads less traveled, but its just one way PE crystals can help us use energy that is otherwise wasted.
Think of possibilities: computer fans that help power the computer, city sidewalks helping power the city, motors that help power the electronics in a car, clothing that turns human movement into charging stations for phones and other electronics in the pockets.
It all may seem a little space age right now, but all it takes is one person to put this to good use and we could have a whole new source of electricity. For more on Piezoelectric Crystals check out Wikipedia or Green Energy Help Files
Oh and now that answer to how has almost everyone held a PE crystal in our hands? PE crystals are used in electric lighters to create the electricity that causes the spark when you push the trigger down. Did you guess right? Let me know and share some of the ideas you have for uses of PE crystals in the comments.
***Update*** May 2011 – India just broke ground on a gorgeous solar-powered sports complex that will harvest piezoelectric energy from the crowds that enter its gates.
