"This is the first observation of magnetic levitation of living organisms as well as the first images of diamagnetics levitated in a normal, room-temperature environment (if we disregard the tale about Flying Coffin of Mohammed as such evidence, of course). In fact, it is possible to levitate magnetically every material and every living creature on the earth due to the always present molecular magnetism. The molecular magnetism is...
Over a 1000-km run, superconducting cables can carry far more power than cables of a comparable size. Even taking into account the energy required to cool them, they lose just a third as much energy in transmission. Just as in the case of optical fibres, the technology has been quietly refined over the years and in some senses is ready to be deployed. This will be costly at first, but with tangible benefits that the wider market may just...
