old technology
probably way expensive

saw that on TED 5 years ago

Lexus makes it. They manufacture luxury cars. Anything they are going to produce is going to be expensive.

hoverboards require metal underneath
you can't use it just any old place
it'll only work is specialized hoverboard grounds

this is literally 20+ year old technology

I really doubt that thing can hold a person. Otherwise they would have shown it in the video.

you mean toyota makes it you fuckin knob

Viral bullshit to sell useless crap.

Meißner-Ochsenfeld-Effect has been known for 82 years, now.

EMDRIVES

Ionocrafts would work, they just need a shitton of energy

This.

Who says they're a woman?
There happen to be guys with long hair and plucked brows and boobs too, you know.

the moment someone says this unironically here on 4chan, I'm gonna stab my eyes out

If it doesn't work over any surface it's not a real hoverboard. Not a practical one, keyword here.

A practical hoverboard can do all of the following:
-hover over any surface
-hover at least 10 cm above the ground
-hover for at least one hour
-accelerate to 15 mph
-not require safety goggles to avoid laser damage to eyes
-not produce noise over 80 decibels


I absolutely reject anything that does not meet all criteria listed as it is not a true and/or practical hoverboard.

>>7354623
>-hover at least 10 cm above the ground
>-accelerate to 15 mph

Even the back to the future hoverboard wouldn't meet those criteria.

>>7351669
Hoverboards haven't been developed (afaik) that can turn like boards that make contact with the ground/snow/water/ etc because they have no medium to drag their edges through to create friction on one side of the board as to allow a sooth turn. How could we overcome this /sci/?

>>7354662
Funny because there actually is already a ducted fan hoverboard that does meet those two criteria. It's just that it's so inefficient that it can only do so for like a minute.

>>7354662

>>7354662
Couldn't meet the "hover over any surface" criterion, too.

>>7354665
You can't. All you can do is have a high thrust that can be used to counter your forward momentum and build sideways momentum in a reasonable amount of time. However a rotor-based hoverboard capable of hovering several feet off the ground would have minimal obstacles to navigate and allow for the wide turns required at moderate speeds.

You would also want to have wheels to allow tackling hills without stopping(or crashing) and even carrying forward momentum into uphill climbing.

The thing is, it did work on water. It still hovered, he just couldn't push off.

>>7355170
By what force? The Jesus Force?

>>7355180

Presumably the same it used to hover on land?

Oh look it's fucking nothing

That's not the only type of hoverboard that exists.

could you use diamagnetism , at least in principle, to create a howerboard that would levitate over any material ? The magnets would have to be absurdly powerful to support a person, but in principle , if you could make an arbitrarily powerful magnet..?

Please stab your eyes out, you bigoted fuck.

Also welcome to /sci/, home of the true SJWs of 4chan.

that's sort of cool until you realize it's essentially just a mini helicopter

>>7360144
That's still cool, just not 'hoverboard' cool.

>>7357633
OP here……thanks man.

>>7351669
It would work. Provided you have the right material under your feet, and the internals of your own hoverboard are supercooled. It's all just magnets and discs very carefully doped with certain minerals.

>>7356888
No.

not sure if serious. that specific board is on par with Solar roadways https://www.youtube.com/watch?v=MMZ2cyNxPwg

Also possible: active field regulation

and if you have a underground prepared with magnets you can even turn your setup upside down.

first vid is made by me, hardware was about 50 euros. could be much cheaper.

Viral advertising. They hid magnets under the concrete:
