Our cups runneth over – the hoverboard is real!
Next year is 2015, which means we’ve finally caught up to Back to the Future II — and its quasi-plausible vision of the future. How’d it do? Well, we don’t have flying cars, we don’t have self-drying clothes, and the Cubs haven’t won the World Series, but we finally have a hoverboard … sorta.
The actual technology — as seen in a variety of hovercraft — isn’t as futuristic as one might think. Hovercraft use blowers to create a large gust of air — above atmospheric pressure — and the difference between the air pressure below the hull and above it creates lift, enabling it to travel over surfaces like land, mud, ice, and water.
A similar technology, magnetic levitation, uses a different method to reach the same end (a hovering vehicle). This is popular with Maglev trains, and theme parks also use magnets to propel linear induction vehicles.
The Hendo Hoverboard, created by Jill and Greg Henderson, relies on the latter technology, meaning that its operating environment is extremely limited. The prototype can only be used over a non-ferrous metal surface like copper or aluminum, though production versions could solve that issue.
According to Engadget, the proof-of-concept can support up to 300 pounds, and future copies should accommodate 500 pounds. And this isn’t just for robust individuals. Extrapolated on a large scale, the technology could levitate houses to mitigate damage from floods or buildings to cancel out the effects of earthquakes.
For now, the Hendersons are relying on a Kickstarter campaign to crowdfund the technology in its infancy. A $299 donation nets you a working Hendo hover engine plus a hover surface, while 10K will buy a real hoverboard. Everyone will get a Whitebox Developer Kit, enabling tinkerers to play with it to their heart’s content (and hopefully arrive at a reasonable facsimile of this). And, as a nod to Back to the Future fans, the delivery date coincides with Marty McFly’s fictional arrival in the “future” — 10/21/2015.
If you’ve got the money, it’s a neat investment. A writer for GigaOM took a test ride and described the experience like “standing on a giant air hockey puck hovering three quarters of an inch above the ground.” It’s got a ways to go, and it won’t be zipping around kitschy visions of the future anytime soon. But the tech has great promise and for more than nerd fantasies.
