ULTRA

A blood powered lamp. Receive lamp, break top, use broken glass to cut finger, drop in the blood, lamp powers up - designer Mike Thompson laments, "The user must consider when light is needed the most, forcing them to rethink how wasteful they are with energy, and how precious it is."

Kind of harsh, but point taken.

On a less extreme and more mass-implementable note, a pilot program in North Carolina has measured energy savings as much as 40 percent, due to a web dashboard that lets home and business owners monitor and control their own use. A simpler more socially-conscious (neighbours-are-watching) version with Tweet-a-Watt/Kill-a-Watt.
