this is the Technology Report.Many automobile makers present their newest designs at car shows around the world. Many designers seek to create the car of the future. One device that is popular among car manufacturers is an autopilot. Autopilot permits a car to drive itself without human control.A recent car show in Geneva, Switzerland also presented other possible designs, including cars manufactured in 3D printers.Rinspeed is a Swiss design company. It demonstrated a vehicle based on the U.S. electric car Tesla Model S, but the Rinspeed car includes a large television and an espresso coffee maker.Frank Rinderknecht is the chief executive officer of Rinspeed. He says he does not want to just sit and watch the steering wheel turn as he rides in a car with autopilot."I want to ride, I want to sleep, relax, watch movies, news, anything else. So that's the vision which we have. That one day on the boring motorway traffic, you just do anything which makes your life better," said Rinderknecht.One of the most interesting ideas presented at the show is a car built on a 3D printer. The German engineering firm EDAG designed the car. The body of the vehicle called 'Genesis' is printed in one piece from a material called thermoplastic.Cristoph Horvath is a spokesman for EDAG."To create a car without the use of any tool. This would be a real revolution for the industry," said Horvath.EDAG says it based its design on a turtle shell. The company says the design provides the right amount of strength and firmness.Other automakers did not look so far into the future. Czech automaker Skoda presented its 'Vision C' model vehicle.
