| Young Inventors' Latest Concepts Students across China, studying in the fields of engineering, science and technology, are developing a range of inventions that they hope will one day be marketable. Here are three examples from the minds of China's young inventors. Foot-Controlled Mouse This new kind of mouse is controlled by the feet instead of the hands, to help handicapped people when surfing the Internet. The new device is called a "surf mouse", and looks like a pair of blue slippers. When users press the slippers with their forefeet, they are clicking the left mouse button; when people press with their heels, they are clicking the right mouse; when they roll their feet over the slippers, they can view Web pages. Dirty Water Filter The "pump of life", a filter, can make dirty water drinkable. The pump is over 30 centimeters long and has a diameter of four centimeters. It has an in-pipe at the top and out-pipe at the end. There are two main parts: the drive zone to pump water and the material zone to eliminate (去除) harmful substances. Rain, fish tank water and coalmine water can all be cleaned in the material zone. The invention could be used for many kinds of disaster relief. Pan told us that water was delivered by helicopters to Wenchuan. If they had sent water-purifying equipment instead, people could have had more water faster after the earthquake. Transformer Vehicle The multi-functional vehicle is named Tranfus. By changing the breadth of tires and the structure of a car, it can become a motorbike or a luggage carrier. The name Tranfus is a contraction of "transforming for us." Traffic jams can make a driver go crazy. The Tranfus can change into luggage carrier, and users could walk with it. When started, the roof transforms, turning into a motorbike. But its inventor doesn't think Tranfus will be on the market soon as some auto companies like it, but none are willing to invest. |
