Wireless power systems could one day beam electricity from space

Forget smartphone charging. When it comes to next-generation wireless power, engineers in Japan are working on a system that can send large amounts of electrical power over considerable distances.
Behind several prototypes and projects is a common idea: the ability to send power from the sky to the ground.
The eventual goal of the research is a huge space-based solar array that isn't affected by earth's weather systems and constantly collects large amounts of energy, which is then sent down to
