DARPA has achieved a major milestone in next-generation energy technology by successfully wirelessly transmitting electrical power over a distance of more than 5 miles, setting a new record for long-range power beaming. This breakthrough represents a significant step toward a future where electricity could be delivered without traditional cables, towers, or physical infrastructure. Wireless power transmission has long been a scientific ambition, but distance and efficiency have remained major ba
