I do engineering models. You like them. Most of you. This channel is created for the popularization of mechanical engineering. I made all the machines that you see here as an educational tool. Old and new concepts of working Perpetual Motion Machines (PMM). Medieval engineering inventions. Kinetic Art objects. Models of Da Vinci inventions. Marble machines. My models of PMMs are motorized versions that were built to illustrate how they were supposed to work in the minds of Inventors. We all miss something that goes beyond the usual scientific explanations. Fundamental Science, Physics Laws and boring Laws of Thermodynamics bring the ‘flight’ of Inventors' ideas to land. Growing Technology … We live in an age of consumption. But many of us are still dreaming and believe that the era of creativity has not gone. My PMM models are built for them. I'd like to inspire you by demonstrating unworkable PMMs that have been designed centuries ago as well as recent ideas.
