Researchers from Japan Space Systems (JSS) recently beamed energy wirelessly from a speeding jet to antennae on the ground.

A satellite no bigger than a washing machine could soon take a major step toward reshaping the future of clean energy. Japan is preparing to launch a spacecraft that will send solar energy wirelessly ...

Robots are already transforming industries here on Earth. The next big challenge is to build massive structures in orbit, ...

Remote-controlled robots could one day build giant solar farms in space, according to a recent trial in the UK.

Ultimately, SSPD-1 served as a feasibility experiment: Can it gather solar power in space and beam it, in the form of microwaves, down to Earth as useful energy? Graphic: Caltech/SSPP The project ...

telecommunications satellites have been sending microwave signals generated by solar power back to Earth since the 1960s. But sending useful amounts of power is a different matter entirely.

telecommunications satellites have been sending microwave signals generated by solar power back to Earth since the 1960s. But sending useful amounts of power is a different matter entirely.

The concept of harvesting solar power continuously from large satellites ... orbit collect solar energy and beam it back to Earth via microwaves as a continuous source of clean energy.

Cheap, abundant and reliable energy underpins the quality of life for all – and one potentially exciting way to do this is space-based solar power (SBSP). It would involve capturing sunlight in space ...
