Electricity Beamed Over Five Miles Without Cables Electricity has been wirelessly transmitted over more than five miles, marking a major breakthrough in long-distance power delivery. The U.S. Defense Advanced Research Projects Agency (DARPA), through its Persistent Optical Wireless Energy Relay (POWER) program, successfully beamed over 800 watts of energy across a distance of 8.6 kilometers (5.3 miles), setting a new record for optical power transmission. The achievement was made possible by a n

Finland Demonstrates Cable-Free Electricity Transmission Finland has developed a wireless power system capable of transmitting electricity through the air without physical cables. Using controlled electromagnetic waves, the system sends energy from a transmitter to a receiver, opening new possibilities for powering remote sensors, devices, and hard-to-reach infrastructure. While not meant to replace power grids, the technology could complement them—especially where wiring is impractical or unsaf
