What Are the Odds of a Perfect Machine? Perpetual Motion Possibilities

In summary, perpetual motion machines are impossible as they would violate the laws of physics, including the three laws of thermodynamics, Newton's laws of motion, Ohms law, Archemede's principle, and Lentz's law. They are considered a pseudoscience and are banned from discussion on many platforms. More information on the topic can be found through reputable sources such as the 4hv wiki, Wikipedia, and skeptical websites.

What are the odds that humans will come up with a 100% (or extremely close to) efficient machine within the next couple centuries. If so, what principle do you think it would work on? How about a perpetual motion machine?

Share your thoughts.

Perpetual motion machines would violate the laws of physics and are thus completely impossible. They will never happen.

However many electric heaters are exactly 100% efficient and energy harvesting devices can have coefficients of performance of well above 1:1.

In what ways would a perpetual machine violate the laws of physics?

The three laws of thermodynamics describe the general problems (and the PMM wiki describes the associated violations) and many claimed PMMS are not well enough developed to take further. But for ones that are, the violations can be anything. Common ones include Newton's laws of motion, Ohms law Archemede's principle and Lentz's law.

PMMs are on the Banned Topics list in the PF Rules (see Info at the top of the page). We list some website that are good resources for your further reading outside of the PF.

1. What is a perfect machine?

A perfect machine is a hypothetical device that operates without any external energy input and is able to generate unlimited energy or movement. It is often referred to as a perpetual motion machine.

2. Is it possible to create a perfect machine?

No, it is not possible to create a perfect machine. The laws of thermodynamics dictate that it is impossible to create a perpetual motion machine that operates without any energy input from an external source.

3. Why do people still search for perpetual motion possibilities?

The idea of a perfect machine has fascinated scientists and inventors for centuries. Many believe that if a perfect machine could be created, it would revolutionize the world and solve many energy problems. However, the search for perpetual motion possibilities is largely considered a futile pursuit.

4. Have any perfect machines been created?

No, no perfect machines have been created. There have been many attempts throughout history to create a perpetual motion machine, but all have failed due to the laws of thermodynamics.

5. What are the potential consequences of a perfect machine?

If a perfect machine were to be created, it would violate the laws of thermodynamics and fundamentally change our understanding of physics. It could also have disastrous consequences, such as causing widespread energy shortages or environmental damage.
