SUMMARY

A perpetual machine is a hypothetical device that can produce useful work indefinitely without an energy input, effectively generating more energy than it consumes. This concept is categorized into two types: perpetual motion machines of the first kind, which violate the first law of thermodynamics, and those of the second kind, which violate the second law. Despite their intriguing nature, perpetual machines are impossible according to established thermodynamic principles.

PREREQUISITES
  • Understanding of the first and second laws of thermodynamics
  • Familiarity with energy conservation principles
  • Basic knowledge of mechanical work and energy transfer
  • Awareness of hypothetical constructs in physics
NEXT STEPS
  • Research the first law of thermodynamics and its implications on energy conservation
  • Explore the second law of thermodynamics and its relevance to entropy
  • Investigate historical attempts to create perpetual motion machines
  • Study the implications of thermodynamic laws in modern engineering applications
USEFUL FOR

Students of physics, engineers, and anyone interested in the principles of thermodynamics and the feasibility of energy generation concepts.

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 ...
