He talks about superconductors and how it doesn't have any atoms or molecules are hitting against each other. With will not create any energy or heat. He talks about how we could place this superconductor in a magnetic field.
He takes what he calls is superconductor that they have put in Liquid nitrogen and puts it on a few magnets and it levitates, not touching the magnets. He also places the superconductor and a magnetic rail and it freely moves around the track. He also moves the track around and it will just keep moving.
This is amazing! That we have found a way to make something to levitate by making something really cold and will magnets and finding material that can hold love 700 times its weight, it just shows that we are one step closer to being able to have our dreams of flying cars.
Of course we would have to do much more research and testing till we can be completely sure that this could happen. But its good enough to me to see that we have an idea of what we can do. Maybe I will finally get my huvor board.
