How close are we to having a real Star Trek type of Tractor Beam?

The water tank in which the procedure was preformed.     G. Spalding/Illinois Wesleyan University So the We Are Technology Team is always reading up about the latest technology and this can be quite an intense task since technology is in our lives in so many ways. Our User Friendly Radio Show crew research for interesting topics to present for the news portion of the radio show, and sometimes we don’t have enough time to share all the cool and exciting things that are going on in the world of technology. So this is one of those articles that I just could not ignore. I just happen to love science fiction and Star Trek is one of my favorites, so I guess if one wants to be on the trail blazing towards technology found in a series such as Star Trek, then I guess the University of Dundee, University of Southampton, and Illinois Wesleyan University are the places to go for creating things such as tractor beams. Apparently an acoustic “tractor beam” that can pull an object by firing sound waves at it has been created by physicists in the UK and US. This is the first time that something larger than a microscopic target has been moved. They were able to demonstrate that enough force on an object around 1 centimeter in size could be held or moved by directing twin beams of energy from an ultrasound array towards the back of an object. This was done inside of a special tank of water. There are three different articles concerning this topic. Please go check them out and see how the world that was dreamed of by writers might actually someday become a reality.
