The U.S. Defense Advanced Research Projects Agency (DARPA) has set a new record for wireless power transmission.

In June 2025, DARPA’s POWER program successfully sent over 800 watts of power across 5.3 miles (8.6 kilometers) using a laser beam in New Mexico.

The test lasted 30 seconds and delivered more than a megajoule of energy. This breaks previous records, which only managed 230 watts over 1.7 kilometers.

The breakthrough could one day power drones during flight or provide energy to remote areas on demand, especially in military operations.
