Record Distance for Moving Objects with Tractors Ray

A team of researchers at the National University in Canberra Australia has managed to move objects “bulky” over longer distances than ever, with aid laser light.

Scientists have made an art of molecular transport step closer to practical applications. Using what they call tractor beams – energy rays that can move objects – Australian experts were able to move particles from one place to another, the distances up to 1.5 meters.

For many years physicists are able to manipulate small particles on tiny distances, using lasers but now, Andrew Rhodes and his team have perfected the technique in Canberra, winning particles travel a hundred times the distance already considerable.

The current method involves launching a laser beam in the sense of transparent glass particles, thus warming the air around them. Center beam that strikes the particles, resulting in attracting them to remain cool hot edges of the beam.

But the heated air molecules moving particles hit the surface of glass and to reject cold heart. Thus, Dr. Rhode explained how, using two laser beams, the particles can be manipulated to move in different directions. The researcher believes that using this technique, particles can be moved even on distances up to ten meters.

Maximum distance the particles travel in Australia team success was limited by the laboratory equipment. Unfortunately, current technology can not operate in open space, because the vacuum created would affect the proper development of the process. However, if the media will evolve will find many possible applications for new technology, such as transporting high-risk substances and dangerous microbes.
