I 'M UNCERTAIN why everybody is consumed with hoverboards, however they are. Maybe would might just blame Back to the Future II and the scene where Marty McFly utilized one. Personally, I am still just waiting for my flying vehicle.
In case you have not been focusing, there are three different working hoverboards that actually exist. Here is an evaluation of the physics of these 3 different boards.
I believe this is the model that is the most like exactly what we would expect of a hoverboard. It's generally just a small helicopter, other than you base on top of the rotors instead of sitting underneath them.
How does it work? For all hoverboards, you need some upward force to push versus the gravitational force. For the Omni hoverboard, this upward force is from the air. The props push air down leading to an upward force on the rotors. Here is a more total description along with some calculations.
Why is it awesome? Similar to a helicopter, you can move both up and down in addition to side to side. If you do not believe this flies like a hoverboard original , I don't think you will discover anything much better. As you can see in the video above, the Omni hoverboard can fly over water or land. It doesn't really matter what is below it.
The Omni hoverboard has 2 major defects. Since this is basically like an electrical powered quadcopter, it needs a battery. Would it eliminate that human or just seriously hurt them?
The Hendo hoverboard came out some time last year. It may not be just like the one in Back to the Future II, however a minimum of Tony Hawk rode it. Also, it seems Hawk is aiding with the next version of the hoverboard.
How does it work? The Hendo engine uses electromagnets that produce changing magnetic fields to communicate with a performing surface area. Generally when these electromagnets change the electromagnetic field that produces an electrical current in the metal surface below the hoverboard. This electrical existing then produces its own electromagnetic field to repel the hoverboard electromagnets. Although the idea appears straightforward, it's hard to obtain it to operate in real life.
Why is it remarkable? It's clearly a skateboard that hovers. That's quite amazing.
The main problem with this hoverboard is that it only hovers over a conducting surface. If you put this over water, the electromagnets would still make altering magnetic fields however without an electric conductor listed below it there would be no repulsion.
The Lexus Hoverboard
Lexus made a hoverboard. It really works too.
How does it work? Once again, this hoverboard uses electromagnetic fields. Instead of altering magnetic fields from an electromagnet, the Lexus hoverboard uses superconductors. When a superconductor is put near a magnet, you can get a levitation effect. That's essentially what occurs here. The magnets remain in the ground and the superconductor is inside the board.
Why is it remarkable? This board is remarkable since it's much smaller sized than either the Hendo or the Omni hoverboard (at least in the meantime). It looks the most like a skateboard that also hovers.
Where does it fall short? Just like the Hendo, this board also needs a special surface area to ride it on. It doesn't work over water or any other surface area that doesn't currently have actually magnets embedded in the ground. Another downside is the superconducting magnets. Superconductors have to be very cold in order to have the levitating homes. This implies that you have to include 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 offers a cool look but you would need to keep adding liquid nitrogen as you ride.
I think we are still awaiting the best hoverboard.
