Japan, always at the forefront when it comes to technology and innovation, seems ready to transform the car industry thanks to a truly sensational innovation: magnetic levitation cars (maglev). This technology is currently still in the testing phase at the Okinawa Institute of Science and Technology. If the trials were to conclude in the best possible way, in the future this technology could bring about a real revolution in the world of transport by eliminating the need to build engines and batteries.
Magnetic levitation, known as maglev, is a technique that allows an object to be kept suspended in the air thanks to the use of magnetic fields. In this way, any physical contact with a surface is avoided. This technology has been used in the railway sector for some time, but now researchers at the Okinawa Institute of Science and Technology want to broaden the scope of its application by using this technology also for cars. This could obviously end up starting a real revolution in cars and also in transport in general.
The magnetic levitation cars developed by the Okinawa Institute of Science and Technology (OIST) are quite different from traditional maglev trains. While traditional maglev trains require a constant supply of electricity to maintain their magnetic fields, the new system patented in Japan requires energy only during startup. Once the initial magnetic field is created, the cars, which are made of diamagnetic materials, remain suspended above the tracks, requiring no additional energy to maintain levitation.
The team at the Okinawa Institute of Science and Technology has developed an innovative track system that features a continuous network of magnets positioned beneath the surface. These magnets interact with specially designed vehicles, made from a combination of powdered graphite and wax, allowing them to levitate just a few centimeters above the track. This configuration eliminates the need for motors and batteries, reducing the weight of the vehicles and improving their energy efficiency. The system could also be significantly more sustainable, with a reduced environmental impact.
Despite the exciting potential of magnetic levitation cars, there are still several challenges before they can become a reality for everyday drivers. One of the main problems is scaling the technology to a practical size suitable for mass production. The experimental prototype developed by OIST is relatively small, and scaling the technology to full-size vehicles will require significant progress.
