He developed several inventions, way ahead of his time: screw air (helicopter), the tank, the submarine, hydraulic pumps, crank mechanisms, automata, calculator, diving helmet, the double hull boat, and car including, but few fully developed.
An example of his talent is reflected in an anecdote in 1502. Leonardo designed a 240 m bridge to cross the Golden Horn (Istanbul). But the Ottoman sultan did not support the project. Finally, more than 500 years later, on May 17, 2006, the Turkish government built the bridge that Leonardo designed.
