Publication: perpetuum mobile of fourth type

In summary, a recent publication in Physical Review discusses the concept of "zero-point-driven" devices, which would be a new type of perpetuum mobile that does not produce any work despite being in a state of permanent rotation. The idea is consistent with the laws of thermodynamics and has sparked interest among the physics community. However, the construction of such devices may prove challenging.

A fresh publication (few days ago) in Physical Review (American Physical Society):

http://prd.aps.org/abstract/PRD/v87/i2/e025021

Abstract: <skipped/technical> The suggested “zero-point-driven” devices — which have no internally moving parts — correspond to a perpetuum mobile of a new, fourth kind: They do not produce any work despite the fact that their equilibrium (ground) state corresponds to a permanent rotation even in the presence of an external environment. We show that our proposal is consistent with the laws of thermodynamics.

Any comments about the "perpetuum mobile of fourth kind" from the physics community/specialists?

Interesting idea, and it does not look impossible to realize. A temperature below 50mK (at 50T magnetic field) requires constant cooling of the environment, but it is possible. The construction of the ring might be challenging.
 

1. What is a "perpetuum mobile of fourth type"?

A perpetuum mobile of fourth type is a hypothetical machine that is able to continuously generate energy without requiring any external input. It is often referred to as a "perpetual motion machine" and has been a topic of interest and debate among scientists for centuries.

2. Is a perpetuum mobile of fourth type possible?

According to the laws of thermodynamics, it is impossible for a perpetuum mobile of fourth type to exist. The first law states that energy cannot be created or destroyed, only transformed, and the second law states that the total entropy (disorder) of a closed system can never decrease. Therefore, any machine claiming to be a perpetuum mobile of fourth type would violate these laws.

3. Has anyone ever created a perpetuum mobile of fourth type?

No, there is no evidence that a perpetuum mobile of fourth type has ever been successfully created. Many people have claimed to have invented one, but upon closer examination, their machines have been found to either rely on external energy sources or to have hidden mechanisms that allow them to function.

4. Why is the concept of a perpetuum mobile of fourth type still studied?

Although it is widely accepted that a perpetuum mobile of fourth type is impossible, scientists and engineers continue to study the concept because it helps to further our understanding of the laws of thermodynamics and energy conservation. It also serves as a cautionary reminder to be critical of claims that seem too good to be true.

5. What are the potential implications if a perpetuum mobile of fourth type was discovered to be possible?

If a perpetuum mobile of fourth type was proven to be possible, it would revolutionize the field of energy production and could potentially solve the world's energy crisis. However, it would also require a complete rethinking of our current understanding of physics, which is highly unlikely to happen.
