Perpetual motion machine inventors do have principles. Unfortunately the physical principles they assume are often ones not obeyed by nature. Let's examine just a few. The principle of unlimited possibility. Anything is possible in nature. The "heavier on one side" seduction. Anything is possible Inventors assume that since we haven't looked at every part of the universe nor have we looked at all possible mechanisms or phenomena, we can't rule out anything. Those who think this way are much like the child who puts two blocks in a box, closes the box, shakes it, then opens it, hoping to find three blocks inside. The "heavier on one side" seduction. The most naive level of perpetual motion seduction is the notion that if a system has more mass on one side of the axle, then that side must swing downward. We can test its stability by turning the wheel to any position whatever. The earliest unbalanced wheel of Bhaskara underwent countless modifications and embellishments over centuries.
