Constrained to a very small track built into the park.

Plus the barrel of liquid Nitrogen you have to carry around is a little inconvenient.

Well, yeah, magnets don't repel against anything except magnets.

Unless there's some physics-shattering discovery some day, there will never be something compact that just repels against the surface of random ground. And no matter how much power you have, it definitely won't be able to repel against water.

At most, perhaps some day after our grandkids are dead there could be super powerful little jets that can force enough air downward in a tiny space to support the weight of a person, but human extinction will probably occur first, and static levitation is impossible.

(They use gigantic machines to generate a magnetic force to levitate a tiny frog, but that kind of force will never be compact nor support any meaningful mass.)

Many superconductor elevation stunts like it have been around Youtube for a while. However; this is being portrayed as a novel idea, which it is not, and a similar hoverboard has 0% chance of being practical considering superconduction is a major ingredient in the recipe. Nevertheless, great PR video!

Um...you mean like this.....

Farthest Flight On Hoverboard - Guinness World Record has been added as a related post - related requested by newtboy.

Um... No.

We're talking about the Back to the Future hoverboard, which is the size of and can be skated on like a skateboard, not just any gigantic machine on which a person could stand and be lifted.

Not equivalent, but related is this sucker like the which I think is the tits:



(The equivalent sells for considerably less on Amazon.)

OK....if that's how you want to be about it! ;-)

Still, it seemed to me that that guy (over water) had something much closer to a 'real' hoverboard than these guys did.

There was also that version that worked over any copper surface,

which I thought was also way 'better' than this version which needs the embedded mag-lev track to work.

The 'over water' guy just needs to miniaturize (although that would make balancing near impossible) to meet your specs.

Just curious, would you accept a pair of skateboard sized (+-) hover-boots as hoverboards, or would that be just a pair of hoverskates?

Hmm. Bring me what you have so far and I'll have my research team think tank it and focus group it before I can get back to you with a firm yay or nay.
