Naomi Kizhner's jewelry serves two purposes: 1) it's decorative; 2) it harvests energy from your body to charge your various electronic devices.
For instance, "The Blinker" gets energy from your blinks. The "Blood Bridge" is more invasive, tapping directly into a vein to power a hydro micro turbine.
However, you can't buy this jewelry because it's really just an art project intended to "provoke the thought about how far will we go to in order to 'feed' our addiction in the world of declining resources."
