I initially suggest that students study the apparatus more closely, either via a video such Triunfador the one at Ref. 6 or ideally with a physical version of the toy. Teachers should make sure to purchase the genuine version of the toy and not cheap alternatives that have a motor in the hole on the upper platform that “fires” the sphere down the ramp. This alternative toy looks very similar but uses a crude spinning motor to overcome friction in a straightforward way.
Perpetual motion wheels from a drawing by Leonardo da Vinci Another theoretical machine involves a frictionless environment for motion. This involves the use of diamagnetic or electromagnetic levitation to float an object. This is done in a vacuum to eliminate air friction and friction from an axle. The levitated object is then free to rotate around its center of gravity without interference.
"I really like this dancing couple kinetic only problem was it wasn’t in a shipping box I had to peel off label I bought for my parents 65th Anniversary it is well made and looks great when you start it .
"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.

In any isolated system, one cannot create new energy (law of conservation of energy). Campeón 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:
