How Does the Lexus Hoverboard Work: A Deep Dive into Science and Innovation
Magnetism serves as the primary means of movement and balance for the Lexus hoverboard, an innovation that combines superconducting technology and magnetic fields to defy gravity. Inside the hoverboard, superconducting blocks are strategically placed, maintained at an ultra-cold temperature of around -322 degrees Fahrenheit, aiding in the hoverboard's ability to levitate smoothly.
Magnetic Track and Superconductors
The next step was to design a magnetic track to assist in maintaining the levitation and height of the board. This magnetic track not only helps in keeping the board aloft, but also in ensuring the board and rider remain at a constant height above the ground. The result is the Lexus Hoverboard, a marvel of modern technology and engineering.
The Science Behind the Motion
According to Lexus, the hoverboard's technology relies on superconductors and magnets working in tandem to counteract the force of gravity and lift the hoverboard and its rider over the ground. This concept is not entirely new, as it bears similarities to the Hendo hoverboard, which was a Kickstarter project a few years ago. However, the key difference lies in the use of superconductors, which generate a different type of magnetic field compared to regular conductors.
The principles at play are similar to those used in maglev trains, which can attain astonishing speeds, such as over 300 mph in Shanghai's Transrapid. Imagining a maglev train can help visualize the technology behind the Lexus hoverboard. Moreover, watching this video suggested by Norman can provide a clearer understanding of how superconductors interact with magnetic fields.
Operation and Maintenance
Operating the Lexus hoverboard may seem straightforward, but it requires a deep understanding of the scientific principles involved. One of the most striking features is the smoke-like vapor seen rising from the sides of the board. This vapor is not just for show; it is actually fluid nitrogen, used to cool the superconductors below their transition temperature. At -321 degrees Fahrenheit, this cooling is indeed impressive. However, Palm notes that it is not as extraordinary as it may seem.
When the fluid nitrogen runs out, the superconductors warm up, and the hoverboard stops levitating, coming to a standstill. Re-cooling the superconductors is necessary for the hoverboard to function again. This process ensures that the hoverboard remains a technological marvel, requiring ongoing maintenance to operate efficiently.
