Sci-fi sound wave device makes Star Trek style tractor beams out of powerful mini-tornadoes that can manipulate large objects

'It seems like every day you see, hear, or read about something that’s being created or invented concerning all sorts of popular science fiction technology, but a fully-working tractor beam was never among them — until now. According to a team of engineers from the University of Bristol, they have successfully managed to develop the world’s most powerful tractor beam, and it’s capable of moving objects around using nothing but the power of sound.

That’s right, with the power of their newly-invented acoustic tractor beam, the team of engineers was able to show that it’s possible to hold particles in mid-air. So far, they have only tested it on a two-centimeter piece of polystyrene sphere, but it’s a good start, considering the technology could have lots of different applications — out on land or even in other locations. Spam_A Spam_B According to the researchers, they have been working on the development of their acoustic tractor beam technology for a few decades now. And a major obstacle has stood in their way: rotating sound fields typically transfer some of their spinning motion to the objects that they are supposed to hold, making them orbit faster and faster up to the point that they become unstable.

Now, the team has managed to find an alternative to conventional methods. The new way, in which the researchers created a device that can create “mini tornadoes” from sound waves alone, is said to use a spinning field to keep objects steady instead. The researchers are now hoping to scale up the use of their technology in order to manipulate much larger objects that they initial tests would allow them to.

According to Dr. Asier Marzo, the lead author of the study from the Department of Mechanical Engineering at the University of Bristol, their breakthrough could provide the much-needed push for a fully-developed and fully-working version that can truly be used for some real-world applications. “Acoustic researchers had been frustrated by the size limit for years, so it’s satisfying to find a way to overcome it,” he explained. “I think it opens the door to many new applications.”'
