Free Energy from Computer Fan. Start Up Project 11


6AIt is not a wonder but a real fact that, we can light a 3 V 1 Watt LED without any battery power. You can harvest that much “Free Energy” from a Computer cooling Fan that is resting in the Junk box. A Computer Fan generates around 1.5 Volts with a current of around 80 mA during its full speed rotation when coming close to a Table Fan. By adding a Joule Thief circuit, we can boost this 1.5V to around 4 volts. Well, that is a good idea. When the Computer Fan is close to a Table fan, the forcing wind from the Table Fan starts to rotate the Computer fan in its full speed. The 1.5V thus generating from the Computer fan appears in its connecting wires. Joule Thief takes this voltage and boosts it to 4V. It is sufficient to light a 3 V 1 Watt LED. The Computer Fan used in the project is an original one without any manipulation and not like the one found in some videos with a hidden battery. Let us see the “Free Energy Magic”. You can also name it as “Wind Power Project”.
