Japan will try to beam solar power from space by 2025.

JAXA, Japan’s NASA equivalent, has spent decades trying to make it possible to beam solar energy from space – which seems like technology for a far-future space anime. In 2015, JAXA scientists successfully beamed 1.8 kilowatts of power, enough energy to power an electric kettle 50 meters away, wirelessly. Now, a Japanese public–private partnership will attempt to beam solar energy from space as early as 2025. The project involves deploying into orbit a series of small satellites, which will beam collected solar energy to ground-based receiving stations hundreds of miles away.

While this already seems a huge step up from a kettle 50 meters away, it’s just the start of the challenge. Creating a satellite array that can generate 1 gigawatt of power – or about the output of one nuclear reactor – is estimated to cost around $7 billion with current technologies.
