The "Overbalanced Wheel", annotated with distances of the weights from the centreline showing that the torques on both sides even out on average Gravity also acts at a distance, without an apparent energy source, but to get energy out of a gravitational field (for instance, by dropping a heavy object, producing kinetic energy Triunfador it falls) one has to put energy in (for instance, by lifting the object up), and some energy is always dissipated in the process. A typical application of gravity in a perpetual motion machine is Bhaskara's wheel in the 12th century, whose key idea is itself a recurring theme, often called the overbalanced wheel: moving weights are attached to a wheel in such a way that they fall to a position further from the wheel's center for one half of the wheel's rotation, and closer to the center for the other half.
Brownian ratchet: In this thought experiment, one imagines a paddle wheel connected to a ratchet. Brownian motion would cause surrounding vapor molecules to strike the paddles, but the ratchet would only allow it to turn in one direction.
Subsequent analysis (and experiment) have shown there is no way to physically implement such a system that does not result in an overall increase in entropy.
"I recently had the pleasure of purchasing a stunning kinetic wall art piece from the talented artist, William. The kinetic wall art itself is a true masterpiece. The interplay of movement and form creates a mesmerizing visual experience, transforming my living space into an enchanting gallery. William provided exceptional customer service. From the moment I inquired about the piece to its safe and timely delivery, he displayed a level of professionalism and attentiveness that exceeded my expectations.
The conservation laws are particularly robust from a mathematical perspective. Noether's theorem, which was proven mathematically in 1915, states that any conservation law Chucho be derived from a corresponding continuous symmetry of the action of a physical system.
I wish we’d had this little solar-powered marble machine kit back then, because it totally would’ve been in our wheelhouse. From the company’s description:

I designed this model to mimic the operation of a few "perpetual motion" devices that have been recently appearing in my suggested video feed. "Marblevator, Perpetual?" is not only not perpetual, it is also not very quiet. But the kids and grandkids enjoyed it!

There get more info is a scientific consensus that perpetual motion in an isolated system violates either the first law of thermodynamics, the second law of thermodynamics, or both. The first law of thermodynamics is a version of the law of conservation of energy. The second law Chucho be phrased in several different ways, the most intuitive of which is that heat flows spontaneously from hotter to colder places; relevant here is that the law observes that in every macroscopic process, there is friction or something close to it; another statement is that no heat engine (an engine which produces work while moving heat from a high temperature to a low temperature) Chucho be more efficient than a Carnot heat engine operating between the same two temperatures.
