Lexus’ SLIDE – The Hoverboard We’ve Always Dreamed Of?
Did you hear? Lexus built a hoverboard.
Ever since Back To The Future, hoverboards have held their place into our collective imagination of what the future should look like, along with flying cars, lightsabers, and space battles. Unfortunately, just as with the rest of that list, the knowledge of how to create a realistically scalable, consumer-ready version of this technology has evaded us. Until perhaps now. In a recent YouTube video, Lexus gave us a glimpse of their brand-spanking-new project, SLIDE, although for only a 16-second clip of the device floating stationary. This clip went viral immediately, with over 5 million views as of June 26th, and many people around the world are wondering: is this finally the hoverboard we have all been waiting for?
Not to rain on your parade, people of the world, but no, the Lexus SLIDE is probably not the hoverboard that inhabit the dreams of sci-fi fans everywhere. There are a few reasons why SLIDE isn’t a fully functioning hoverboard, all of which lie in how the board was constructed. As you can see in the video above, the board can actually float a couple inches off the ground, and in that respect the hoverboard works fine. The board itself has a very sleek look to it, with a bamboo and carbon fiber body, and certainly looks the part of a functioning hoverboard. The part of the video that catches most people’s eyes, though, is the wisps of smoke rising from the side of the board. That smoke, although very cool and adding to the aesthetic of the board, is actually a product of the liquid nitrogen inside the board, needed to cool down the superconductor that makes the board hover in the first place. Although this all sounds very futuristic, but it’s nothing we haven’t seen before.
Basically, SLIDE uses magnets. Sure, a fairly complex magnetic setup, reliant upon superconductors and the Meissner Effect to float, but still, it’s all just magnetics. And anyone who knows anything about magnets knows that for a magnet to repel or attract anything, there has to be another magnet for it to interact with; herein lies the problem. For SLIDE to stay afloat, it needs a magnetic material to float above, which in terms of consumer transportation, would require every road and sidewalk to be paved on top of beds of magnets, or more realistically, with a type of magnetic concrete that doesn’t exist yet. However impressive of a job Lexus did when putting all of the superconducting technology into one slick package, it isn’t scalable unless you’re ready to fill the world with magnetic tracks. In fact, Lexus did create one such magnetic skatepark exclusively for SLIDE, complete with jumps, stairs, and ramps, and was where Lexus shot the teaser for SLIDE (shown above). Spanish site El Patín discovered the park in the small village of Cubelles just outside of Barcelona.
Unfortunately, Back To The Future set our sights a little high with their hoverboard. Although we’ve seen the portable communication devices from Star Trek make their way into modern society, an easy-to-ride, cheap, accessible, scalable, and safe hoverboard isn’t going to become ubiquitous anytime soon. SLIDE isn’t totally useless – not by any stretch – as it could certainly be used in entertainment facilities like laser tag or trampoline houses, but in terms of the near-term wide-spread uses for hoverboard that we all really want, SLIDE isn’t ready to reach that mark. In fact, SLIDE wasn’t even intended to make such a splash online, and was only supposed to be a marketing campaign for an unannounced Lexus car. “Let’s be frank, it’s not novel,” Maurice Durand, a Lexus spokesperson, told WIRED. “There are other hoverboards. To a degree, we weren’t expecting [the reaction].”
Well, there you have it. With a combination of chance and good advertising, Lexus inadvertently made many people across the world believe, or at least upon first look become excited about the possibility that SLIDE is a fully functioning hoverboard. In truth, Lexus has taken existing technology and put in a very impressive package, one that very well could be a Back to the Future hoverboard if not for the technical restraint of needing magnets under you at all times. Although hoverboards in particular probably won’t be in our future this decade, there are still many technologies from sci-fi making their way into our daily life in the coming years, and plenty that we can be just as excited about.
