Looking forward to a future where laser beams replace power lines, DAPRA's Persistent Optical Wireless Energy Relay (POWER) program has set new records for transmitting more power wirelessly over longer distances.

    Previously, the POWER system managed to use a laser to beam 230 watts across one mile (1.7 km) for 25 seconds, and an undisclosed lesser amount of power as far as 2.3 miles (3.7 km). Now, DARPA has managed to increase this to 800 watts for 30 seconds at a distance of 5.3 miles (8.6 km).
