Ever since Marty McFly took to the air in the 1989 classic Back to the Future II,humanity has been eagerly awaiting the arrival of a real, fully-functional hoverboard. Since then, tinkerers and scientists the world over have launched countless attempts at building such a device, and now, after more than 25 years of trying, technology has finally caught up with our far-fetched dreams. Thanks to a startup by the name of Hendo Hover, the hoverboard is finally a real thing that exists in the world that you and I inhabit.
How is such a thing possible? Well, according to the company’s Kickstater page, the magic behind the Hendo Hoverboard lies in its four disc-shaped hover engines. These are essentially giant downward-facing electromagnets that work together to create a powerful magnetic field which literally pushes against itself, thereby generating the lift which levitates the board above the ground.
