Laws were Meant to be Broken: Perpetual Motion Devices

(Created 4 October 2005)

Perpetual motion devices have always been seen as a feat unattainable with the current laws of thermodynamics. Accordingly, the second law of thermodynamics states that thermal energy (heat) is special by concluding all forms of energy can be converted into heat, but it is not possible to convert the heat back fully in its original form. In other words, heat is a form of energy of lower quality. A machine cannot produce the same amount of energy used to keep it running because some energy is lost in friction [1]. Scientists, throughout the ages, have attempted to create perpetual motion devices despite physics. Leonardo Da Vinci attempted to create a perpetual motion device (shown later) using a wheel and an odd number of weights to keep the wheel turning. Feynman attempted to make a Brownian motor using Brownian motion discovered by Robert Brown1.[2] Nature seems to be laughing in front of our faces when it comes to perpetual motion devices. The atom uses perpetual motion! The electrons around the nucleus circle the atom forever. This perpetual motion is what tricks many scientists into thinking that perpetual motion devices can be achieved.[3]

Aims of Proposed Study
Creative ideas for perpetual motion devices have been created for years and none have worked. We are going to attempt to re-create two perpetual motion devices: Da Vinci's overbalanced wheel and the magnetic engine. Though these devices have been tested and went unsuccessful, we are going to try improve each one, finding any flaws, and see if we can somehow get a perpetual motion device to work.

I. Overbalanced wheel
We will first cut 2 circles out of wood that is 1 foot in diameter. We will then cut a smaller circle in each big circle, so each big circle would then have a 6 inch in diameter hole. We will connect each circle to each other using little metal...
