How one of the most Promising Hoverboards Really Work
I 'M Not Exactly Sure why everyone is consumed with hoverboards, but they are. Perhaps would might just blame Back to the Future II and the scene where Marty McFly used one. Personally, I am still just waiting for my flying automobile. In case you haven't been taking note, there are three various working hoverboards that really exist. Here is an evaluation of the physics of these 3 different boards. Omni Hoverboard I think this is the design that is one of the most like exactly what we would anticipate of a hoverboard. It's generally just a little helicopter, other than you base on top of the rotors instead of sitting underneath them. For all hoverboards, you need some upward force to press versus the gravitational force. For the Omni hoverboard, this upward force is from the air. Why is it awesome? Just like 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, I do not believe you will discover anything much better. As you can see in the video above, the Omni hoverboard can fly over water or land. It does not actually matter what is below it. Where does it fail? The Omni hoverboard has two major defects. Is the flight time. Because this is essentially like an electric 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 super harmful. What if you crash into a pedestrian standing on the ground? Would it kill that human or simply seriously injure them? Hendo Hoverboard The Hendo hoverboard came out some time last year. It might not be similar to the one in Back to the Future II, but at least Tony Hawk rode it. Also, it appears Hawk is assisting with the next variation of the hoverboard. Basically when these electromagnets alter the magnetic field that produces an electrical current in the metal surface area underneath the hoverboard. This electrical present then produces its own magnetic field to repel the hoverboard electromagnets. Why is it awesome? It's plainly a skateboard that hovers. That's pretty remarkable. Where does it fall short? The main issue with this hoverboard is that it only hovers over a conducting surface. If you put this over water, the electromagnets would still make changing magnetic fields but without an electric conductor below it there would be no repulsion. The other little problem is that it doesn't ride like a skateboard. Hopefully this can alter with the help of Tony Hawk. The Lexus Hoverboard Yes, it's true. Lexus made a hoverboard. It truly works too. I'm still not sure why they did it. How does it work? Again, this hoverboard utilizes magnetic fields. Instead of altering electromagnetic 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 exactly what occurs here. The magnets are in the ground and the superconductor is inside the board.
Why is it remarkable? This board is incredible since it's much smaller sized than either the Hendo or the Omni hoverboard original (at least for now). It looks the most like a skateboard that likewise hovers. Where does it fall short? Much like the Hendo, this board likewise requires an unique surface to ride it on. It does not work over water or any other surface that does not already have actually magnets embedded in the ground. Another drawback is the superconducting magnets. Superconductors need to be very cold in order to have the levitating homes. This means that you need 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 very cold magnets. That provides a cool look however you would need to keep adding liquid nitrogen as you ride. I think we are still waiting for the ideal hoverboard.
