Heat to Power

REQUIREMENTS FOR THIS

1.four TEC1-12705 thermo electric modules

2.LM7805 voltage regulator

3.5v usb output

4.3 capacitors

5.bc 327 and 337transistors

6.resistors

7.two diodes

HOW TO DO

First connect all the euipments as shown in the circuit diagrams its very simple one can easily connect without any guidence .Heat the thermoelectric module with the help of your had by rubbuing then heat is generated this heat us converted to electrical power and is stored in power bank by connecting to the output

cost is some wat less
