The Back to the Future trilogy is a highly enjoyable trio of time-travelling adventures, but it is Part II that presents the creators’ vision of 2015. However, Back to the Future predicted a far more outlandish 2015 than what actually happened just three years ago. One correct prediction about 2015 is the presence of hoverboards, like the one Marty McFly (Michael J. Fox) ‘borrows’ to make a quick escape.
Although they aren’t as widespread as the film perceives, hoverboards actually exist. The first real one was created in 2015 by Arx Pax, a company based in California, United States. The company invented the Magnetic Field Architecture (MFA™) used to provide the levitation of a hoverboard. To explain how this works as simply as possible, it means that the board generates a magnetic field, which in turn creates an eddy current. That then creates another opposing magnetic field. These magnetic fields repel each other which provides lift.
This is an amazing achievement in bringing a completely fictional idea from a film first aired in 1989 to reality. This work has even gone so far as to be recognised by NASA, who in the same year of 2015 entered into a Space Act Agreement to use the same MFA™ technology to create ‘micro-satellite capturing devices’, allowing them to manipulate CubeSats.
Rechargeable magnetsThe engines consist of charged magnetics that can be recharged after the magnets are drained.
Copper ‘hoverpark’In order to enjoy this hoverboard, the ‘hoverpark’ must be coated in copper, a conductive material.
Magnetic levitation With the induction of two opposing magnetic fields, electromagnetic repulsion occurs, causing the hoverboard to levitate off the ground.
Marty McFly was able to hover over any surface, even water, with the hoverboard
