What are Nikola Tesla's inventions?

What inventions by Nikola Tesla are employed in the Tesla Roadster and Model S?

• The electric cars of Tesla Motors are incredible and their story inspirational. As is the story of the inventor they named the company after. I was wondering what inventions, perhaps related to AC currents or induction motors are relevant in the engineering of Tesla Motors' cars.

• Answer:

  Radios, AC motors, mechanical oscillators - Tesla toyed around with lot of stuff. To be more precise: Every car built by Tesla motors uses http://en.wikipedia.org/wiki/AC_induction_motor - the kind Tesla came up with. This helps in http://en.wikipedia.org/wiki/Regenerative_brake which makes the car more efficient. That is, the energy expended when braking is converted back to electricity to be used in the car. Tesla was the father of http://en.wikipedia.org/wiki/Radio_control - it is used in different forms, mainly for controlling weapons. Tesla had patents for AND logic circuits which are the predecessor for http://en.wikipedia.org/wiki/Transistor and the conversion of DC to AC, which is another core tech used in electric cars - batteries are DC, motors are AC. The transistor is also used in every chip and every computer on board the car, so that is another way Tesla has influenced the car. So yes, Tesla's inventions are a part of the Tesla cars. Everything around you is likely to have something or the other to do with Tesla.
