The Professor of Physics was surrounded by doctoral students. He was discussing the laws of thermodynamics vis a vis perpetual motion machine.
You cannot get something for nothing, because matter and energy are conserved and you cannot break even – because there is always an increase in disorder; entropy always increases. Many people thought otherwise and devoted their lives to inventing such a machine.
Critics called it lamentable, degrading, and insane to pursue the vision of past ages ………..
The students just nodded.
The Museum of Unworkable Devices at Lock Haven University in Pennsylvania has a full gallery devoted to such devices. Visit it when you can.
The eternal nature of the motion that is expected here is the reason for failure. For many insects with a very short life-span the perpetual motion toys could be a source of free energy for many generations. Even our solar system is a perpetual motion system in a much larger time frame. Innumerable generations of human beings continue to enjoy the energy of sun gratis during this time. Unfortunately, the academics translated perpetual as infinite. Many good inventions could not be suitably used because of this little technicality.
We need such machines, today. A focused effort to increase the time-period of such motion along with synchronization between many machines could be the source for large amounts of very cheap green energy.
I want a presentation from each of you on the probability of success for such a strategy.
The students left contemplating the revolutionary strategy.
