i have an idea to produce electricity, tell me if it work or not?

Question

if i fix a strip of rubber on the side of railway coach and wheel on platform which rotates due to motion of train by rubbing with that rubber strip and further wheel is connected with shaft and alternator to produce electricity.will it work, reply plllzzzzzz

Answer 1

Yes, certainly.

Though the train could never produce enough electricity to power it - and it would in effect be losing power because of the extra friction.

If you're trying to make a perpetual motion machine, I'd advice you to read 'voodoo science', read up on the laws of thermodynamics - and forget it.

Answer 2

Yes, it would work, much like an alternator on a car works to recharge the battery and operate the electrical system while the engine is running. (A car's alternator is operated by a belt attached to the engine.) Part of your description sounds like you're incorporating a static electricity generator, which may not be as efficient as a belt-driven generator.

But it is not free energy. The energy of the wheels comes from the driveshaft of the train's engine, which is powered by diesel fuel. Your device siphons off a tiny amount of energy through friction, The energy transferred is very small, effectively unmeasurable, so it looks like it's free but a precise measurement could tell the difference in fuel consumption when the device is connected. Chances are very good that the train engine already has an engine-driven generator that efficiently produces electricity for the train.

Answer 3

It will slow the train down so that the train has to burn more fuel to speed back up again. There are much more efficient ways to produce electricity but no free lunch

Answer 4

Sure but since Diesel trains already have generators to turn the motors that make them move, why add something to do the same job less efficiently ?

Answer 5

No it will not work
