"This moving wooden art is the second of two pieces I bought for a large entry hall. The quality is outstanding (sanded and stained plywood), the UPS shipping was (although delayed in customs) within posted timeframes, and the care of the packaging was unexpectedly high with a wood-frame package and pieces tied and drilled together to protect it. Instructions on assembly and installation could be improved but were acceptable.

"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 click here 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.
Since weights further from the center apply a greater torque, it was thought that the wheel would rotate forever. However, since the side with weights further from the center has fewer weights than the other side, at that moment, the torque is balanced and perpetual movement is not achieved.[28] The moving weights may be hammers on pivoted arms, or rolling balls, or mercury in tubes; the principle is the same.
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:
A device powered by radioactive decay from an isotope with a relatively long half-life; such a device could plausibly operate for hundreds or thousands of years.
In any isolated system, one cannot create new energy (law of conservation of energy). Ganador a result, the thermal efficiency—the produced work power divided by the input heating power—cannot be greater than one.
In some cases a thought experiment appears to suggest that perpetual motion may be possible through accepted and understood physical processes. However, in all cases, a flaw has been found when all of the relevant physics is considered. Examples include:
One classification of perpetual motion machines refers to the particular law of thermodynamics the machines purport to violate:[19]
Link Drop a marble into the top of this tabletop sculpture, and it rolls down a ramp and back into itself endlessly.
A common example is devices powered by ocean currents, whose energy is ultimately derived from the Sun, which itself will eventually burn out.
