Generating Electricity Chemically and Physically.

[ISamson]

Hello,
I have been interested in making electricity by trying to construct small generators or taking advantage of chemical reactions.
I have found a bike electric generator, but I did not know how to spin it constantly. I am looking for how to make electric currents of 8-20 volts for some home experiments.
I know I could use batteries, but they always go flat.
I thought about using a Van De Graff generator, but I did not know of how to.
Do you have any ideas?

P.S. I wish to only use materials available at home. I have copper wires, test-tubes and vinegar.

No idea what you are really trying to do. Every source of electricity requires some source of energy, be it a chemical one, be it a mechanical one. Are you looking for a way around? There is no way around. To make electricity using bike generator you have to find a way to spin it constantly, period.

Most reliable approach is to just use power supply and mains electricity.

Yes, I was wondering how to make electricity with chemical reactions or mechanical ways. Do you know how to?

Spinning constantly the bike generator will work. There is no magic way of making that happen, you need to use either wind, or falling water, or some heat engine, or rotate it manually.
