Hoverboard Breakthrough


Recommended Posts

It looks cool, but it's expensive and impractical, though a good way to dupe money out of the scientifically illiterate. From what I can tell, the hoverboard is just a bunch of super conductive material cooled by liquid nitrogen. It uses superconductivity to hover over metal. Most likely there is metal right below that cement, water, etc. It makes more sense to make a hoverboard out of a quadcopter since that doesn't require everything around you to be covered in metal, is cheaper and can arguably even fly. Philip Mason did a video on another of these recent 'hoverboard' claims that are based on superconductivity.

Liquid Nitrogen has been around since 1883.

Superconductive materials that can be superconductive at the boiling point of liquid nitrogen has been around since 1987.

Congrats, this technology is 28 years old.

If someone can market a hoverboard park where you can ride around on these things on top of terrain that is riddled with magnets, more power to them. It might be fun.

You need magnets under the ground to ride this thing? I thought it worked using earth's gravity?

Yes, you need magnets under the ground. The hoverboard contains superconducting YBCuO or a similar material, and the ground has magnets in it. The magnetic fields from the permanent magnets generate eddy currents in the YBCuO and because it is superconducting, the magnetic field lines cannot penetrate into the material. Therefore, what holds up the board is magnetic pressure. The observed phenomenon is the counterbalance between the upward force of the magnetic field pressure and the downward force of gravity.

Well then that's a far leap from Back To The Future I reckon.
