Levitation and Tractor Beams using Acoustic Holograms, Science Fiction becomes Science Fact.

Sound is not often thought of as being a physical force, music may make you move your feet but no one would believe that it could lift you out of your seat. That was until this week when an international team of researchers led by Bristol University demonstrated the latest advancements of acoustic projection that is able to build acoustic holograms that can levitate objects or act as a tractor beam.

While technology that uses projected sound to manipulate physical objects has been maturing in labs for the last few decades the latest technology might just be good enough to escape the lab and actually lead to real products.

The Hendo Hoverboard in Space, NASA Talks Tractor Beams.

Arx Pax and their Hendo Hoverboard technology are heading for space. After attracting much attention Arx Pax this month announced their partnership with NASA, a partnership to take their magnetic technology to space. Sadly NASA isn’t interested in seeing astronauts zipping about on hoverboards but instead they will be creating a tractor beam system to move around micro satellites.

As a mechanism to generate publicity the Hendo Hoverboard was extremely successful, as a hoverboard not so much. This was due to the requirement of the ground being covered in specific metals for the board to hover everywhere. Like the Lexus Slide hovering cannot be achieved on just any surface such as that covering the real world. Luckily satellites are already covered in the required metals making the magnetic magic work just fine.

The Ultrasonic Tractor Beam and Sonic Screwdriver Move a Step Closer…

The power of energy in wave form is a fundamental part of our understanding of life, it is still a science in its infancy.

It is also the key to many of science fictions greatest inventions; tractor beams, sonic screw drivers and even levitation. These futuristic devices will only become a reality when we can convince light and sound to act counter intuitively, to pull instead of just push.

Recently a team of Scottish and American scientists have pushed (or more precisely pulled) the boundaries of how much pull force they can achieve using sound. With a million times more power than previous tractor beams the team were able to move a 1 cm large triangular shaped object
