A typical bike generator can produce 100 watts. If you pedal for an hour a day, 30 days a month, that's (30 x 100=) 3000 watt-hours, or 3 kWh. That's less than 1% of what a typical family uses in a month (920 kWH). You generated 0.3% of your energy, and continue to get 99.7% from the grid.
Furthermore, how does a dynamo generate electricity?
The generator/dynamo is made up of stationary magnets (stator) which create a powerful magnetic field, and a rotating magnet (rotor) which distorts and cuts through the magnetic lines of flux of the stator. When the rotor cuts through lines of magnetic flux it makes electricity.
How much voltage does a bicycle dynamo produce?
Lastly, dynamo power varies depending on the speed of the bike (Between 0 volts and 12 volts.) Lithium ion cells need a 4.35 volt charge. Would it be better to use a regular voltage regulator you get a radio shack or a switching voltage regulator.
How does an electric generator produce electricity?
It contains a set of electrical conductors wound in coils over an iron core. The rotor generates a moving magnetic field around the stator, which induces a voltage difference between the windings of the stator. This produces the alternating current (AC) output of the generator.
