Why is perpetual motion impossible? For example, can’t you just redirect some of the energy produced from a generator into keeping itself running?
In: Physics
A generator “produces” less energy than it uses… It’s more like a “Transformator” rather than a “generator”. Let’s say you are using a diesel generator to produce electricity. Some of the diesel energy goes into electricity, but most of the energy is wasted in heat, sound, gases, etc. You could use some of the electricity to help keep the machine going but what’s the point? You supposedly wants some electricity, why would you water electricity to produce less electricity?
If you use a battery to power a dynamo to produce electricity you’ll end with less energy than you started with. Same as the previous example, you lose energy in friction, heat, noise, etc. You can’t even transmit electricity through cables without lose some of it.
