Perpetual motion machines – do they exist in the world?
Thread Content
I’m thinking of using a generator and a motor to create a perpetual motion machine – is that possible? The motor is powered by the generator, while the generator’s kinetic energy comes from the motor; as long as human effort is used to provide kinetic energy to the generator to generate electricity, it will in turn drive the motor. Can this achieve perpetual motion?
Although I know it’s impossible, I still want to achieve perpetual motion through everyone’s efforts and wisdom! Do you know what the lowest power consumption of air conditioners is these days? 45W! I believe this figure will go even lower in the future! Isn’t the Earth itself a kind of perpetual motion machine?
Theoretically, perpetual motion machines do not exist; as mechanical devices, they incur energy losses.
Where does the power for your generator come from? Whether it’s through manual operation or some other method, a source of power must be provided to the generator.
Reply to 2# Tao Ke: The Earth is not a perpetual motion machine; it relies on other sources of energy such as solar energy. Energy does not appear out of nowhere, nor does it disappear without a trace; it merely transforms from one form to another.
Mm-hmm, maybe when there’s no need to eat anymore, perpetual motion will become possible
I invented a time machine; the original poster should go and check out the year 9000
It may be feasible in theory, but it is not feasible in practice at the moment.
I’ve seen a toy on the street: it’s a toy for performing acrobatics on a pole; as long as you apply an external force to it, it will keep flipping over the pole continuously! It’s a demonstration of perpetual motion! I wonder if anyone else has seen this kind of toy?
There is energy loss, so there can be no perpetual motion machine.
The poster’s idea is impossible. Firstly, mechanical losses are too significant; in addition, electromagnetic losses are also considerable. There are also constraints such as Earth’s gravity to overcome, so it’s impossible for it to keep running indefinitely!
