Nowadays, cars use batteries and motors to move, but this way is inefficient because overcoming friction and gravity takes most energy. Japan has a solution: magnetic levitation.
Will magnetic levitation replace batteries and motors? Researchers at Okinawa Institute of Science and Technology (OIST) created a track that provides magnetic levitation without external power.
By “external power,” we mean the power needed to generate the initial magnetic field. Once this is done, objects can move on the track without using batteries or motors.
What does this invention consist of? It uses diamagnetic materials for cars and magnets along the tracks to create an intense magnetic field that makes objects “float” on the surface.
The researchers used pulverized graphite and a chemical process to create a plate with magnets arranged in a grid. This eliminates friction, making movement more efficient.
What are the challenges that need to be overcome? The prototype is small, but to make it practical, we need to reduce kinetic energy at the surface level and prevent vortex damping.
In conclusion, magnetic levitation could replace motors and batteries once these limitations are overcome. It would eliminate obstacles like friction and gravity, making movement more efficient.
