how can i convert this voltage into current , i mean something like a step down transformer, but what kind of a circuit would use this high voltage?

[raveeshakh]

See, you can use this high coltage to charge a capacitor.

Is it rochelle salt inside?

What ever it is, would it be possible to create a farm of this stuff and somehow use nature to generate electricity?

[raveeshakh]

It could be ,I am not sure. Yes, if we are able to make an object vibrate using natural energy, electricity could be generated.

[venu1591]

please clarify me about the energy produced in ligther is heat or electric energy?

please replly soon as we are working on it as a project

thanks

In the lighter, the mechanical energy is used to generate a high voltage pulse by the phenamenon of peizo electric effect.This voltage creates a spark.

have some more curry

eh 1500v :P

Static electricity is supposed to START at around there, and if you and hear and see it, its around 10,000 volts or more

@raveeshakh How about making a layer of it underneath roads and/or paths? Even the motion of the sea could generate power surely? lol I'm sure the governments are well aware of this but they're too busy making money out of oil and other fossil fuels...

See, here a voltage pulse is produced.Its magnitude could be around 500volts.
