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.

What’s the power draw?
If it’s low enough, might be economical for transportation. I imagine putting down metal sheeting that doesn’t have to be resurfaced every few years might be economical too.
Will the Interstates be repaved with steel?
This one is more practical:

I think it works by an effect caled eddy currents. Whenever a magnet is moved towards or across a conducting, non-magnetic surface, it generates currents inside the metal which repel the magnet. Hook some wires and a load to the metal surface and you have a generator.
Unfortunately after an initial levitation away from the facts, the liberal’s head explodes and the whole thing comes crashing down. They are working on that.
Hover-hockey?
Only in the air hockey sense. See post #4.
Ice skate are more practical.
It depends on how thick the metal needs to be. Would aluminum foil work?
#3 You can hover along high voltage copper wires.....
Be careful what you wish for. When your car runs out of as or the engine quits, you can coast to the side of the road. What are you going to do one thousand feet in the air when you run out of fuel or the engine quits? Gravity is a cruel teacher.
