Researchers have reportedly beamed solar power from space to Earth without a single wire—and they say it’s a first. The experiment is a part of Caltech’s Space Solar Power Project. The researchers conducted the power transfer experiment using the Microwave Array for Power-transfer Low-orbit Experiment, or MAPLE, which is a small prototype aboard the in-orbit Space Solar Power Demonstrator (SSPD-1) that launched this past January.
