Impossible Inventions

When Leonardo da Vinci invented the tank, car, helicopter, glider, parachute, submarine, lift and telescope, over 500 years ago, he was considered a dreamer. Or even crazy. Today he is understood to be a genius, ahead of his time. This book collects ancient and modern inventions. Some are revolutionary, others comical, others were simply impossible. But each of them testifies to the extraordinary imaginations of their inventors. You will find here a flying bicycle, bubble telegraph, passenger clouds and passenger birds, mechanical chess players, a water clock, a concentration hood and many more incredible ideas.
