I 'M UNSURE why everybody is consumed with hoverboards, but they are. Perhaps would could simply blame Back to the Future II and the scene where Marty McFly utilized one. Personally, I am still just waiting on my flying cars and truck.
In case you have not been taking note, there are three various working hoverboards that actually exist. Here is a review of the physics of these three different boards.
I believe this is the model that is the most like exactly what we would expect of a hoverboard. It's basically just a small helicopter, other than you stand on top of the rotors instead of sitting underneath them.
How does it work? For all hoverboards, you require some upward force to press against the gravitational force. For the Omni hoverboard, this upward force is from the air. The props press air down resulting in an upward force on the rotors. Here is a more total description in addition to 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 think this flies like a hoverboard, I do not think you will find anything better. As you can see in the video above, the Omni hoverboard can fly over water or land. It doesn't actually matter exactly what is listed below it.
Where does it fall short? The Omni hoverboard has two major flaws. Is the flight time. Because this is essentially like an electrical powered quadcopter, it needs a battery. Batteries are heavy, so you can only power the propellers for a number of minutes of flight time. Second, this thing looks extremely harmful. What if you crash into a pedestrian standing on the ground? Would it eliminate that human or just seriously hurt them?
The Hendo hoverboard original came out some time last year. It might not be much like the one in Back to the Future II, however a minimum of Tony Hawk rode it. Likewise, it seems Hawk is aiding with the next variation of the hoverboard.
Generally when these electromagnets alter the magnetic field that produces an electrical existing in the metal surface beneath the hoverboard. This electric current then produces its own magnetic field to fend off the hoverboard electromagnets.
Why is it remarkable? It's plainly a skateboard that hovers. That's pretty amazing.
Where does it fall short? The main issue with this hoverboard is that it just hovers over a performing surface area. If you put this over water, the electromagnets would still make changing magnetic fields but without an electric conductor listed below it there would be no repulsion. The other little issue is that it does not ride like a skateboard. Ideally this can alter with the help of Tony Hawk.
The Lexus Hoverboard
Lexus made a hoverboard. It actually works too.
How does it work? Again, this hoverboard utilizes magnetic fields. Rather of altering magnetic fields from an electromagnet, the Lexus hoverboard uses superconductors.
Why is it amazing? This board is remarkable due to the fact that it's much smaller sized than either the Hendo or the Omni hoverboard (a minimum of in the meantime). It looks the most like a skateboard that likewise hovers.
Just like the Hendo, this board likewise needs a special surface area to ride it on. It does not work over water or any other surface area that does not currently have actually magnets embedded in the ground. You can see the water vapor condensing in the air from the extremely cold magnets.
I think we are still waiting on the best hoverboard.
