Escher (1)

If you take a closer look at this picture by the Dutch artist Escher, it looks as if the water continue to run all by itself, forcing the wheel to move. If you install an electric generator connected to the wheel, you would actually have a perpetual motion machine - if it were possible to build the installation in physical reality. But that´s exactly what you can´t do! And why not?
