An American inventor, Dean Kamen, says he has invented the world’ s first self -balancing individual transport vehicle called the Segway Human Transporter.
The Segway looks like a long stick with two wheels. The stick has handles for a person to hold while the wheels are connected by a platform. The person stands on the platform and holds the handles and turns them to go left or right. The vehicle moves forward or backward when the person moves his body in that direction.
The Segway has computers and gyroscope devices to make it move and balance. It is powered by batteries that can be re-charged in a few hours by using an electric outlet. It can travel at a speed of nineteen kilometers per hour, cost less than ten cents a day to operate.
Mister Kamen says the Segway could replace cars in crowded city centers because it was designed to reduce pollution and solve other environmental problems in cities. However, it was not designed to travel on roads.
Mister Kamen is a successful inventor and president of the DEKA Research and Development Company near Manchester, New Hampshire. He has invented about one -hundred other device, including some important medical devices such as an insulin pump for people with diabetes, a device to open blocked blood vessels in the heart and a wheelchair that can move up steps.
The Segway will be for sale to the public next year at about three - thousand dollars. Several businesses are testing the vehicle now, including the United States Postal Service and the bookseller Amazon dot com. Some letter carriers will try riding the vehicles to deliver the mail. Amazon workers will use them to find books in their huge storage buildings. Police in two cities also will test the vehicles to see if they can be used for law enforcement.
Some technology experts have criticized the Segway vehicle for being potentially dangerous to ride and for not protecting the rider from bad weather. They say it holds only one person while other small vehicles can hold three people. And some people may use the vehicle to avoid walking and getting exercise. However, other experts say the vehicle is interesting and could be used in many ways in the future.
It is implied in the passage that______.
