An Unusual Airplane Powered by Microwaves (微波动力飞机)
Canadian scientists have successfully tested an unusual airplane. The airplane is not powered by fuels. It is powered by microwaves. Microwaves can be produced by equipment on earth. When the microwaves hit the bottom of the plane's wings, instruments change them into a more usable form of energy - electricity powers the plane's engine.
The plane was developed by the Canadian government and the University of Toronto. The plane is called the sharpfire. The sharpfire is much too small to carry people or equipment. It was built only to see if the technology would work. Sharpfire is made of light weight wood. Its wings are about three and one half meters across. In its first public. A future microwave plane will be much larger than the sharpfire. The main reason for using microwave energy to power an airplane is to end the plane's need to carry fuel. An american researcher says this technology will be very common in the next century.
