| "visitors to the 2010 world expo in shanghai will be able to go sightseeing in super cool cars with no drivers," shanghai city officials (***) said recently. when a prototype (样品) of the six-seat car was shown to the public, it interested many people. "the car will help visitors feel what high technology (科技) is and help them enjoy the tour of the world expo site," said a professor from tongji university. the prototype, 4.5meters long, 1.7 meters wide, and 1.6 meters tall, runs along a white line. the car costs around 300,000 yuan to build and can reach a top speed of 50 kilometers per hour. according to the researchers, visitors will be able to drive the car anywhere in the world expo site by pressing a button. if they want to get off or stop the car, all they need to do is just to press the button again. "people can rent one of these cars for a whole day or just take a ride in it from one place to another," the professor said. about 400 to 500 of these cars will be made for the expo in 2010. the cars will have radar (雷达) to help them get around. they will mainly use solar (太阳能) batteries (电池) and lithium (锂) batteries. as they have no need of drivers and oil, these cars will help save energy and human labor, and cause no pollution to the environment. | |
