Simply put, bladeless fans are fans without blades. They work by sucking in air at their base and then blowing them out through several holes in their ring. The fan is reported to have been invented by James Dyson, who calls it the "Air Multiplier." Just like the flying jetpack, it earned a spot in Time's list of notable inventions of 2009. And just like the jetpack, it was not the first of its kind. The first bladeless fan was actually patented in 1981 by a Japanese company called Tokyo Shiba Electric. Although Tokyo Shiba's bladeless fan was never manufactured, James Dyson's initial design of a bladeless fan design looked so similar to that of Tokyo Shiba Electric that the patent office refused to grant him a patent. The patent granted to Tokyo Shiba had already expired, but the patent office still required something substantially different before it could grant a new patent to James Dyson. Dyson's patent manager, Gill Smith, did not deny the similarities between both bladeless fans but said the difference between them was the "technology."
More recently, however, General Motors made a self-driving car in 1958 that adjusted its steering wheel based on the alternating currents given off by a wire placed inside the road. While the vehicle did actually drive itself, it does not qualify as the first autonomous vehicle because it depended on wires placed inside the ground. The world's first autonomous vehicle was made by S. Tsugawa and several of his colleagues at Japan's Tsukuba Mechanical Engineering Laboratory. However, German engineer Ernst Dickinson is regarded as the pioneer of the autonomous car. In 1987, he developed the VaMoRs which was capable of traveling more than 90 kilometers per hour (55 mph) for about 20 kilometers (12 mi). Seven years later, he made the VaMP, which could recognize road signs, know its own position in a lane, detect other vehicles, and even decide when to change lanes. And a year after that, he and his team made another autonomous vehicle which traveled from Germany to Denmark. The vehicle had a maximum speed of 180 kilometers per hour (111 mph) and was controlled by a human for about 5 percent of the journey.}
However Mr Kwon warned that young people should be cautious when seeking such operations.
