I've become aware of and interested in the idea of energy harvesting. In fact it's more than an idea, as there are devices already using this
technique amongst us.
Capturing electricity by way of recovering vibrational type energy is known as piezoe electric energy.
This kind of energy, as we already know, is all around us all of the time and it's there for the taking. At the moment, there is a mass roll out
going on for things like traffic monitoring devices (oh joy).
Another technique for capturing spare, and otherwise wasted energy is known as pyroe electric energy. This harvests energy
from high temperature sources and is stable up to 1200 degrees. This could be a superb way of catpuring what I would hope to be a great percentage,
and a significant amount of all that energy that escapes into the air from industrial process.
The grand idea at the moment is grow the ability to capture the spare energy from nearly everything. It could be from sounds around us, the roar of
jet aircraft taking off and landing, a voice, spare heat from rocks cooling down after a sunny day, furniture being moved around,tectonic plates, you
get the drift, absolutely everything!
There has been talk of course of smaller scale devices that can use extrmely small amounts of power, but what sruck me, was the fact that there are
ideas being towted around, that suggest enough energy could be harvested to allow collection in central distribution stations, there being possibly
billions of miniture power stations feeding into a grid. I guess all these micro amounts would add up to a fairly respectable amount of available
power. All free of course (ha ha).
I've posted a couple of addresses below for those who wish to know more on this.
