AI Thread Summary
A perpetual machine is a hypothetical device that can produce useful work indefinitely without an energy source, effectively generating more energy than it consumes. There are two types of perpetual machines: the first kind violates the first law of thermodynamics, while the second kind violates the second law. Both types are considered impossible according to established thermodynamic principles. The concept remains a topic of interest in physics and engineering discussions. Understanding these machines highlights fundamental laws of energy conservation and entropy.

hi everybody, i have a question to which am unable to find the answer.
what is a perpetual machine?
this is related to thermodynamics and also what i understood there is a first kind and a second kind also...any detailed info from anyone please..
thanks

Perpetual machine is the one which can produce useful work indefinitely. They can do more work (produce more energy) than they actually consume. They are of course hypothetical though as they violate the principles of thermodynamics.
 
thanks ...

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms'

Assume that this is a case where by sheer coincidence, two sources of coherent single-frequency EM wave pulses with equal duration are both fired in opposing directions, with both carrying the same frequency and amplitude and orientation. These two waves meet head-on while moving in opposing directions, and their phases are precisely offset by 180 degrees so that each trough of one wave meets with the crest of the other. This should be true for both the electric and magnetic components of...
