Andrew Carnegie: “Pioneering doesn’t pay.” How true this statement is you might see when studying Tesla’s robot boat of 1898. Today, the Nikola Tesla Museum in Belgrade is proud to build replicas of Tesla’s world-first robot vessel and sell it to other museums. When Tesla presented his new marvel at Madison Square Garden, people shied away: nobody understood the significance and importance of Tesla’s invention. And the inventor added to the feeling of mystique by stating that his mind controlled the movements of the robot boat. What we can learn from this, Carnegie already said. In addition, Tesla built a so-called logic gate into the radio-control mechanism of his “submarine destroyer”. When in the 1950’s this essential safety mechanism (I/O barrier) was re-invented, it couldn’t be patented because of Tesla’s patent 613,809: “Pioneering doesn’t pay.”
