DARPA has achieved a major milestone in next-generation energy delivery by successfully wirelessly transmitting electrical power over a distance of more than 5 miles, setting a new record for long-range power beaming. With no cables, towers, or physical connections involved, the test demonstrates that electricity can be delivered through the air using directed energy technology. Wireless power transmission has been a long-standing scientific goal, but achieving meaningful range and stability has
