This is just downright cool. This Kickstarter project aims at bringing eternal light. No batteries needed. This mini flashlight is powered by the touch of a human body. A thermoelectric generator converts your body heat into electricity that powers a small LED.
This $35+ gift could be left in cars, attached to your keychain, or simply stored in your emergency kit. When you need light, simply touch the Lumen and be illuminated.
