Hoverboard? Still in the Future

It was annoying that the article said:<p><i>But when the 190-pound visitor stood atop the 100-pound board, one gentle push was enough to send him spinning across the room over a cushion of air.</i><p>This is very poor writing since there is no &quot;cushion of air&quot; involved, the air is not supporting the weight of the board and rider, it&#x27;s a magnetic system after all. It would probably work almost exactly the same in vacuum.

Now that their kickstarter is up, people are already streaming in to back it. I bet most of them will completely gloss over this gem of a sentence: &quot;Currently, this surface needs to be a non-ferromagnetic conductor.&quot;<p>While it does have some applications even with that limitation, it&#x27;s far from a practical hoverboard, and it&#x27;s very misleading to be talking about other uses of the technology as if it already exists. They seem to be getting ahead of themselves by extolling their &quot;design focus&quot; when they don&#x27;t have the product people expect from them yet, and possibly (probably) never will.

I don&#x27;t want an hoverboard. I want an hovercar. Replace roads with a sheet of copper and put grass over it.

Some interesting rewards in the Kickstarter. <a href="https://www.kickstarter.com/projects/142464853/hendo-hoverboards-worlds-first-real-hoverboard" rel="nofollow">https:&#x2F;&#x2F;www.kickstarter.com&#x2F;projects&#x2F;142464853&#x2F;hendo-hoverbo...</a><p>I do like the White box idea. I wonder though at the price where they start and if thats going to eat the profit generated. (I don&#x27;t know, they could be very cheap to produce at scale.)

Having non-skateboarders demonstrate their invention was a poor choice. They seriously lack the balance needed to make this look appealing.<p>I hereby offer my balance, free of charge if you need someone :)

You need resistance to sideways motion (lateral friction?) for this to work.

The Verge has a better video on the device: <a href="http://www.theverge.com/2014/10/21/7025795/riding-hendos-hoverboard-levitation" rel="nofollow">http:&#x2F;&#x2F;www.theverge.com&#x2F;2014&#x2F;10&#x2F;21&#x2F;7025795&#x2F;riding-hendos-hov...</a>

I guess this needs to operate over a conductive surface? Would saltwater work?

Does anyone know if the physics checks out? Can producing an eddy current create a repelling force that levitates? Why hasn&#x27;t anyone thought of this before?

Stick four or five of these on a skateboard:<p><a href="http://www.jetcatusa.com/p60.html" rel="nofollow">http:&#x2F;&#x2F;www.jetcatusa.com&#x2F;p60.html</a>

I don&#x27;t really get why a hoverboard would be better than a regular skateboard anyways. It&#x27;s a solution looking for a problem.

I thought I just read a few months ago that we&#x27;d have superconducting EM drive hoverboards any day now?<p>How disappointing...

Does anyone know how built in batteries can provide enough power to support a 190 lb person?

Someone forgot Newton&#x27;s 1st Law of Motion, and it&#x27;s evident in all these videos. In other words: It&#x27;s impossible to steer a device like this .
