. Lexus built a skate park in Barcelona, Spain specifically for the project. The system was built as a promotional demonstration, not for public sale.

Conception

The overall project took about 57 weeks from start to finish. The SLIDE was teased in June and officially revealed August 5, 2015. Dietmar Berger, a magnetic levitation engineer, and Ludwig Schultz, a pioneer of superconducting

Technology

The main focus of the demonstration is the levitation of the hoverboard, achieved through the use of

superconductors cooled by liquid nitrogen. Superconductors are conductors that have no internal resistance as long as they are kept below a certain temperature. When a metal has no internal resistance, a current running through the metal will run forever without a power source. When a superconductor is subjected to a magnetic field, the superconductor aligns itself with the magnetic field and floats on top of it. Superconductors only have zero internal resistance when cooled to a certain temperature. In order to achieve this the system uses liquid nitrogen to cool it down to . Even though liquid nitrogen cools down the superconductors, it also boils at the same temperature. This makes it difficult to have a constant supply of liquid nitrogen to continually cool down the superconductors; the system can only operate for an average time of about 20 minutes on maximum liquid nitrogen onboard capacity.

The magnetic track pulls the board along the path. All the uphill and downhill slopes of the track were specifically designed to ensure the magnetic field has enough momentum to pull the board.
