At the moment when we talk with satellites, we use polarised light, which can only vibrate on a single plane, because it's not affected by turbulence in the air. But this is extremely slow, as only one bit of information can be carried by each particle of light.
In order to speed this up, physicists have been looking for a way to encode more information into photons - and in the '90s they began investigating twisting light, which can be sent like a corkscrew across long distances. This is known as orbital angular momentum, or OAM, and it opens up the potential for ridiculously fast and secure communication.
Scientists from Japan have harvested solar energy using an exceptionally large number of light absorbers to relay photons via antennas into one final energy acceptor. This two-step sequence closely mimics natural photosynthesis, resulting in greater and more efficient energy transfer.
