Laser propulsion is a form of beam-powered propulsion where the energy source is a remote (usually ground-based) laser system and separate from the reaction mass.

Just as air causes lift on the wings of an aeroplane, light can do the same trick, researchers have said. The effect, first shown in simulations, was proven by showing it in action on tiny glass rods.

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...
