///@newscientist: The first experiment to transmit power to Earth from space could lead to a space-based solar power station within 10 years, according to one of the researchers involved.⁠
Such a station would benefit from greater exposure to the sun, due to the lack of clouds and atmosphere along with the ability to avoid nighttime darkness. However, the difficulty of designing and making structures large enough to be useful but light enough to launch by rocket has made such a facility impractical.⁠
In a step forward, Ali Hajimiri at the California Institute of Technology and his colleagues launched the Microwave Array Power Transfer LEO Experiment (MAPLE) to space in January 2023. Two months later, they successfully beamed the first power to Earth, after which they ran the experiment for a further eight months.⁠
