lexus\' new hoverboard is cool, but will it fly?
This is a hovercraft.
This flying skateboard nicknamed \"slide\" will be publicly tested for the first time on Wednesday (Aug. 5)
The company posted a short video on YouTube this week.
The video shows smooth planks floating on seemingly ordinary cement in the skate park, causing some hovercraft enthusiasts to guess, and finally, someone makes a flying skateboard that you can ride on a half pipe or sidewalk.
But if you think lexus\'s new toy will change you from \"back to the second part of the future\" to Marty McPhee (

Lexus\'s slides can\'t actually hover over normal cement. [

Maglev or maglev is used inside the slide to maintain itself (and its rider)
According to the company\'s website, the company hovers on the ground, which says the board operates on \"Super conductors and permanent magnets cooled by liquid nitrogen.
Because it uses a material that can conduct electricity at zero resistance at less than a certain temperature, lexus\'s suspension board is slightly different from other maglev technologies, such as the Super suspension board. high-
High-speed maglev trains from Japan, China and other countries.
The maglev train is lifted from the track and pushed forward through the traditional magnet (
A magnet with a magnetic field generated by current).
The magnet is located under the train compartment and is repelled by other magnets embedded in the train track.
The interaction between the two sets of magnets allows the train to resist gravity and keep \"floating\" in the air \".
But the conductor in lexus\'s hovercraft works a bit differently.
When cooled to a certain temperature, they produce a strong current, and the strong current generated by the magnet in turn creates a strong magnetic field, rejecting other magnetic fields that may be generated by magnets located nearby.
This exclusion keeps the hovercraft in the air.
In order to keep the high-temperature conductors in the suspended skateboard working, Lexus people use liquid nitrogen to cool them to cold temperatures.
In the YouTube video, you can see a white, smoke-like substance pouring out of the hovercraft.
This is the water condensation or fog generated when liquid nitrogen hits the air around the conductor.
What you didn\'t see in the Lexus video released last month was the magnets under the hoverboard that repelled the heat.
All you see under the board is plain concrete.
But, according to skateboarding experts at El patin, a Spanish skateboarding site, this concrete may be more than just eyes.
A contributor to the site went to the skate park built by Lexus in a city of Cubelles in Barcelona, where it is said the company will make its debut next week.
The El patin writer said in a blog post that the park is \"not exactly what it looks like \".
\"The Hidden magnet, according to El patin, the small-room skate park is made of plywood and very thin concrete layers.
In other words, it is not a real skate park, but it looks like a skate park.
As Lexus mentioned on its website, hoverboards use both magnets and \"permanent magnets \".
\"According to El patin, in the specially built skate park, these permanent magnets are laid like tracks, hidden under the wood and concrete surfaces of the park ramp and under other surfaces.
This hidden track creates the illusion that hoverboards move freely in skate parks like regular skateboards.
But in fact, the board can only move on the track. [

It can\'t hover on any surface, which makes lexus\'s latest tech toy a bit useless for anyone who can\'t get into the special magnetized skate park.
However, this is not the first time a company has manufactured a suspended skateboard that can only be used in very specific locations.
In December 2014, innovators behind the Hendo hovercraft met their Kickstarter funding goals.
But their future skateboards can only work if they are placed on a copper surface.
The Hendo Hoverboards contain four magnets that alternate the magnetic field and induce the rejection of the magnetic field on the copper surface below the hoverboards, Eric Palm, deputy director of the National High Magnetic Field Laboratory at Florida State University, told Live Science in December.
Hendo\'s hovercraft will be made in a specially made copper-
According to the company that created the board, \"hover Park\" was painted on October \".
So, you won\'t cruise on the sidewalk on the Hendo board very quickly either.
If you want a hovercraft that can be used in a more natural environment (i. e.
