In case you haven’t been paying attention, there are three different working hoverboards that actually exist. Here is a review of the physics of these three different boards.
Omni Hoverboard
Omni Hoverboard
I assume this is the version that is the maximum like what we'd expect of a hoverboard. It’s basically only a small helicopter, except you stand on top of the rotors in preference to sitting underneath them.
How does it work? For all hoverboards, you need some upward force to push in opposition to the gravitational force. For the Omni hoverboard, this upward pressure is from the air. The props push air downward resulting in an upward force at the rotors. here's a greater complete rationalization along with a few calculations.
Why is it awesome? similar to a helicopter, you may flow both up and down as well as aspect to facet. if you don’t suppose this flies like a hoverboard, I don’t assume you will find anything higher. also, as you could see within the video above, the Omni hoverboard can fly over water or land. It doesn’t definitely depend what's under it.
Where does it fall short? The Omni hoverboard has most important flaws. First is the flight time. when you consider that this is basically like an electric powered powered quadcopter, it needs a battery. Batteries are heavy, so you can simplest power the propellers for a couple of minutes of flight time. 2d, this thing appears terrific risky. What if you crash into a pedestrian status at the floor? would it not kill that human or just significantly injure them?
Hendo Hoverboard
The Hendo hoverboard got here out some time remaining 12 months. It won't be just like the only in returned to the destiny II, however as a minimum Tony Hawk rode it. also, it seems Hawk is helping with the subsequent model of the hoverboard.
How does it work? The Hendo engine uses electromagnets that produce converting magnetic fields to interact with a engaging in floor. essentially when these electromagnets change the magnetic field that produces an electric cutting-edge inside the metal floor below the hoverboard. This electric modern-day then produces its very own magnetic area to repel the hoverboard electromagnets. although the concept appears straightforward, it’s tough to get it to paintings in real life.
Why is it awesome? It’s clearly a skateboard that hovers. That’s pretty awesome.
Where does it fall short? The primary hassle with this hoverboard is that it most effective hovers over a accomplishing surface. if you put this over water, the electromagnets might nevertheless make changing magnetic fields but with out an electric powered conductor underneath it there would be no repulsion. the other small trouble is that it doesn’t experience like a skateboard. with any luck this may alternate with the assist of Tony Hawk.
The Lexus Hoverboard
Yes, it’s true. Lexus made a hoverboard. It really works too. I’m still not sure why they did it.
How does Hoverboard work? Again, this hoverboard uses magnetic fields. Instead of changing magnetic fields from an electromagnet, the Lexus hoverboard uses superconductors. When a superconductor is placed near a magnet, you can get a levitation effect. That’s essentially what happens here. The magnets are in the ground and the superconductor is inside the board.
Why is it awesome? This board is excellent because it is very smaller than either the Hendo or the Omni hoverboard (till now). It looks the most like a skateboard that also hovers.
Where does it fall short? Just like the Hendo, this board also demands a special surface to ride it on. It does not work over water or any other surface that doesn’t so soon have magnets embedded in the ground. Another drawback is the superconducting magnets. Superconductors need to be very cold in order to have the levitating properties. This means that you need 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 very cold magnets. That gives a cool look but you would have to keep adding liquid nitrogen as you ride.I guess we are still waiting for the perfect hoverboard.
