ECONOMIST: Wireless charging

The same approach has been used in ground-based experiments to beam one kilowatt of power over a distance of several kilometres, notes Peter Fisher, a physicist at the Massachusetts Institute of Technology.

It produced a beam with 300 terawatts of power (several hundred times the capacity of America's entire electricity grid).
