Wireless power systems could one day beam electricity from space

Researchers continue to push power transmission boundaries, but a lot of work remains

To get to that stage, there's a lot of development work to be done, including the major task of reducing transmission losses.

Japan's space agency, which is pursuing the idea, admits that the idea of harvesting solar energy in space isn't new. Previous projects in other countries have been closed due to lack of political support for such a system.

Nevertheless, the space agency is continuing to push researchers on the technology. But it remains realistic. "It will take significant time and effort to overcome the many hurdles on the pathway to the realization of the solar space power system," it said.
