Electricity has been a boon and without it, we cannot even think of surviving but there might be development of such situations, where there is a complete absence of electricity or there might be locations without the accessibility to such energy. So, what do you do in such situations? Will the batteries last long enough or provide sufficient energy? The answer is a hand powered generator. It can provide power for everything, from your radio to your cell phone. It is not difficult to operate a hand powered generator because they function like any other generator with the exception of the energy, which is initially provided by one’s arm or hand, instead of hydro power or coal energy.
Mechanism of a hand powered generator
A generator works on the principles formulated by Michael Faraday. This principle was that a wire which is conductive in nature, when passed via a magnetic field, produces power in the wire. Once the wire coil is spun around the magnet, a source of electric current is produced. This is how energy is produced with the spinning of the coil. Through this principle, generators are powered with the help of gas, fuel or others. But a hand powered generator works with the turning of coils manually around the magnetic field, for the generation of current or power.
Using generator powered manually
It is very easy to use a hand powered generator. Some of the gadgets have the generators built within them; these are inclusive of a light, radio etc. Then there are specific ones, like in cell phones containing hand cranks. With a connector attach it to your phone and then crank it with the hand crank. This will charge your phone and you can use it without a battery charger. A hand powered generator is great for various emergency situations.
