Jewelry that harvests energy from your veins

"Naomi Kizhner, an industrial designer and graduate student from Hadassah College in Jerusalem, has designed jewelry that theoretically extracts energy from the wearers own body. The ‘speculative’ jewelry is embedded into the person’s veins and uses their blood to turn small wheels inside the device. 

As Naomi notes, the jewelry is not meant to be a practical energy source, but a discussion piece “about how far will we go to in order to ‘feed’ our addiction in the world of declining resources.”

The project is called ‘Energy Addicts’ and consists of three pieces of jewelry: The Blinker, The E-Pulse Conductor, and The Blood Bridge. On her website, she says “The work delves into a world in which there is a significant decline, which forces humanity to seek all the more forcefully for alternative ways of cultivating power. The suggested solution to the dilemma is based on the idea of biological wealth, harvesting energy directly from the body.” via iflscience.com
