Ale Patent!

There are things in heaven and earth that philosophers have never dreamed of. But there are none that inventors have not dreamed of.

When, at the turn of the 15th and 16th centuries, Leonardo da Vinci invented a tank, a car, a helicopter, a hang glider, a parachute, a submarine, an elevator and a telescope, he was probably considered a dreamer. Or even crazy. Today it is said that he was a genius ahead of his time...  

This book is an imaginative review of ancient and modern inventions. Crazy, ahead of their time, funny, unsuccessful or even impossible. But always - testifying to human fantasy. Here you will find a personal cloud maker, a flying bike, a bubble telegraph, an ice gramophone record and many other incredible ideas.
