Peltier charging on a CFL Joule Thief
A 400 watt Peltier module is shown here picking up energy from a 2″ toroid coil used in the Slayer007 low voltage CFL Joule Thief circuit. The energy is captured in a 10uf 35 volt capacitor and then released through 3 white LEDs. The charging up of the capacitor is shown on a meter. An earth ground is also shown in and out of the circuit to show the improvement in efficiency of that additional connection.
