In practise, itÂ´s impossible to create a physical system isolated -which is a condition for the construction of perpetual motion machine. For instance, the Universe is a phycal system aislated in first aproximation because it doesnÂ´t change matter/energy towards outside -you canÂ´t create a Universe or anything from the Nothing (if you arenÂ´t God).
I have read the link and I think itÂ´s interesting but you would have to redefine the Foundations of Physics if you were capable to make it. It would be as if I were able to find how to construct a square of the same area that a circle given by means of only a finite number of steps with compass and straightedge: If I reach it, I would need to redefine what is a point and the relationship between it and the other elements of Geometry because of it comprobated imposibility (Lindemann,1882).
