Scientists Move Discs With Nothing But Light


Making our dreams of traveling via hoverboard a less-distant reality, Japanese researchers have developed a way to move magnetically levitated graphite discs with nothing but light.
Depending on where the light (in the form of a laser beam) is focused, it controls the direction that the disc travels, according to a study by scientists at Aoyama Gakuin University. The laser changes the temperature of the graphite, which alters how the disc interacts with its magnetic field, resulting in movement.
