Energy harvesting devices capture energy from the environment, convert that energy to electricity, and put it to work. The energy could come from the sun or other (man-made) light sources, or from vibrations, wind, or water. While this technology is not new, the ability to harness that power and use it as the sole source of energy for small embedded devices is.

In our Deep Green Editor's Choice section, we look at technology helping design green into today's new products.
