When it comes to climate change and reducing carbon footprints, most attention is paid to the big-ticket items: wind farms, solar, hybrid vehicles, battery technology. But could capturing portions of lost energy be as worthwhile, collectively, as pursuing the big targets? From the heat energy lost in the normal operation of the typical combustion engine, to the energy absorbed by the ground as it's walked on, to the flushing of a toilet - will these sources of "free energy" ever be harnessed at a large enough scale to make a difference? Or will attempts to collect, store, and re-use this energy remain on the fringes of the green movement?
Here's the latest device - similar to the toilet retrofit above - coming soon to a sink near you (?)
