The Navy Is Working on Underwater Wireless Charging Stations for Robot Subs
Unmanned submarines will get charged faster, making them more available for missions.

The U.S. Navy is developing an underwater charging station for its unmanned undersea vehicles. The technology, which does away with cables, will make it easier for drones to recharge at sea.
Wireless charging technology, also known as inductive charging technology, was pioneered commercially for smartphones and tablets. It involves simply setting your phone down on a flat charging mat. Wireless chargers emit an alternating magnetic field, which induces an alternating current in a receiver coil in the device. However, wireless charging hasn't become universal thanks in part to its relative slowness versus using a wired charger.
