Dec 17, 2019 · 9 Is the reason we don't have any perpetual motion machines because of the first law of thermodynamics? That's one of the reasons, and it applies to a perpetual motion machine of the first …

Jan 25, 2024 · The “perpetual motion machine of the second kind”—meaning an impossible machine that destroys entropy— is named after the classic perpetual motion machine (of the first kind), …

Apr 24, 2025 · A perpetual motion machine of the second kind is a machine that spontaneously converts thermal energy into mechanical work. When the thermal energy is equivalent to the work done, this …

Mar 5, 2019 · Why can't we make a perpetual motion machine by using a magnet to pull up a piece of metal, then letting it fall back down? [duplicate] Ask Question Asked 7 years, 1 month ago Modified 7 …

Aug 30, 2024 · There is a presumption that a perpetual motion machine is impossible since it would break the laws of thermodynamics. Of course, it is possible that the laws of thermodynamics could …

Jul 12, 2020 · Closed 5 years ago. I am not a physicist, but I know the first law of thermodynamic (conversation of energy), and I have connected this with an idea that came to my mind some time …

Oct 12, 2021 · 1 Unfortunately for humanity, there is no way to get work out of a perpetual motion machine without dropping the "perpetual". The short answer is that the amount of energy in a closed …

With careful control of the movement of the magnets (or any weight, magnetic or not), you can achieve some net forward motion by taking advantage of friction, since friction is non-linear. A slow …

Wouldn't a machine that runs taking no energy from outside but sometimes needs to be restarted, such as pendulum clock, be considered a perpetual machine? It just needs to be restarted one or two …

I have been recently made aware of the following motor, which uses two magnets and a wheel to generate motion, and the creator of this machine claims that this motion is perpetual. Here is a …
