It was just last month that Lexus revealed its new hoverboard, which was powered by magnets. The company had been working on the project for a long time and finally felt the project was worth revealing to the public.
This week, Lexus launched yet another teaser, this time in the form of a video, showing the hoverboard floating across the ground. Nitrogen-cooled semiconductors make it all possible, and that's why it appears to steam off with frosty air.
The only catch to using this hoverboard is that it requires a magnetic surface, which most concrete sidewalks are not. So it's difficult to say this device is useful in real-world conditions, but it's pretty awesome in the controlled conditions it's in.
Nonetheless, it's an awesome proof of concept that we're sure will help with research for future products.
