THE ENERGY FROM THE RING

ENERGY RINGSean Hodgins (Hodgins Sean) loves building small electronic gadgets. One of them — a ring that turns body heat into light. The ring is made of aluminum — an excellent conductor of heat, which is necessary for the generation of electric energy. To convert heat into electricity is the Peltier module. The Peltier module converts heat that goes from the ring into a small voltage, and the circuit Board amplifies the current. Currently, the efficiency of the device depends on the temperature of the air, but Hodgins is developing a new scheme to make it work at any temperature.
