Is it theoretically possible to make a hoverboard?

sure, why not. There are many existing technologies that make objects hover. Getting that technology small enough to fit in a board is the problem, but I have no reason to believe it's not possible.

quantum locking works, but you need a supercool floor for that

You need a good battery

>Average human (American) mass: 80 kg
>Force to counteract gravity ~ 800 N
>Exhaust velocity of some sort of ducted fan ~50 mph ~ 22 m/s
>Required power would be ~17.6 kW, i.e. about 24 horsepower

You need a way to fit a 20-30 hp engine and power source capable of sustaining that (efficiency around 40% if you're lucky), so about 50 kW

until we get really good at material science and nuclear engineering I don't think you can make these things in board-form, unless you had some sort of magnetic sidewalk they'd work on or were remotely supplied power ala WiTricity

It is already possible.

4 RC turbines ~1600N.

50-60k bucks...

Is it possible for any theory to be probable?

doing it with air is cheating.
I mean the earth does have a magnetic pull. Its just very weak.
Maybe if there was some strong diamagnetic generator...

Ok now includes batteries, housing, support structure, etc...

I'm not a naysayer but it's harder than just buying motors. You might get something cool that can hover with a person on it but like, surfboard size not skateboard

I'm sorry we didn't invent anti-gravity for you in a fucking 4chan thread

there's nothing theoretical about it
It's possible to make a multi-ton aircraft hover you think we can't do it with a little plank?

No.

Look up Meissner - Ochsenfeld effect.
