Wireless power has now been beamed 5 miles through the air to make popcorn
Just don't stand in the way
The U.S. military has set a new record for wireless power transmission, beaming a laser carrying more than 800 watts of power across a distance of 5.3 miles (8.6 kilometers).
The test, performed by the U.S. military's Defense Advanced Research Projects Agency (DARPA) as part of its Persistent Optical Wireless Energy Relay (POWER) program, is a key step toward unlocking the near-instant beaming of power.
It also smashes previous records set by the POWER program, which previously beamed 230 watts across 1 mile (1.7 km) for 25 seconds, and a smaller, undisclosed amount of power as far as 2.3 miles (3.7 km).
