I 'M UNCERTAIN why everybody is obsessed with hoverboards, but they are. Possibly would could simply blame Back to the Future II and the scene where Marty McFly utilized one. Personally, I am still simply awaiting my flying vehicle.
In case you haven't been focusing, there are three different working hoverboards that really exist. Here is a review of the physics of these 3 different boards.
I think this is the design that is one of the most like exactly what we would anticipate of a hoverboard. It's basically simply a little helicopter, other than you base on top of the rotors instead of sitting beneath them.
How does it work? For all hoverboards, you require some upward force to push against the gravitational force. For the Omni hoverboard, this upward force is from the air. The props press air downward leading to an upward force on the rotors. Here is a more complete description together with some computations.
Why is it remarkable? Much like a helicopter, you can move both up and down in addition to side to side. If you don't think this flies like a hoverboard, I do not believe you will find anything much better. As you can see in the video above, the Omni hoverboard can fly over water or land. It does not truly matter exactly what is below it.
The Omni hoverboard has 2 significant defects. Considering that this is essentially like an electric powered quadcopter, it requires a battery. Would it kill that human or just seriously injure them?
The Hendo hoverboard came out a long time last year. It might not be much like the one in Back to the Future II, but a minimum of Tony Hawk rode it. It seems Hawk is assisting with the next version of the hoverboard.
How does it work? The Hendo engine uses electromagnets that produce altering magnetic fields to communicate with a performing surface area. Basically when these electromagnets change the magnetic field that produces an electrical present in the metallic surface area below the hoverboard. This electrical existing then produces its own magnetic field to repel the hoverboard electromagnets. Although the idea appears uncomplicated, it's challenging to get it to operate in real life.
Why is it awesome? It's plainly a skateboard that hovers. That's quite amazing.
The primary issue with this hoverboard is that it only hovers over a performing surface. If you put this over water, the electromagnets would still make altering magnetic fields but without an electrical conductor below it there would be no repulsion.
The Lexus Hoverboard
Yes, it holds true. Lexus made a hoverboard. It truly works too. I'm still not sure why they did it.
How does it work? Once again, this hoverboard utilizes electromagnetic fields. Instead of altering magnetic fields from an electromagnet, the Lexus hoverboard original utilizes superconductors. When a superconductor is placed near a magnet, you can get a levitation effect. That's basically what happens here. The magnets remain in the ground and the superconductor is inside the board.
Why is it remarkable? This board is awesome since it's much smaller than either the Hendo or the Omni hoverboard (at least for now). It looks the most like a skateboard that likewise hovers.
Where does it fall short? Just like the Hendo, this board also requires an unique surface area to ride it on. It doesn't work over water or other surface area that does not currently have magnets embedded in the ground. Another drawback is the superconducting magnets. Superconductors need to be extremely cold in order to have the levitating residential or commercial properties. This implies that you have to add something like liquid nitrogen (-320 F or 77K) to keep them cold. You can see the water vapor condensing in the air from the extremely cold magnets. That gives a cool appearance but you would have to keep including liquid nitrogen as you ride.
I think we are still awaiting the best hoverboard.
