Under its <strong>POWER (Persistent Optical Wireless Energy Relay) program<\/strong>, DARPA successfully transmitted <strong>800 watts of power over a distance of 8.6 kilometers<\/strong> in a test conducted on June 15, 2025. This historic test marks the <strong>longest-range high-power wireless energy transfer<\/strong> to date.<\/p>\n\n\n\n<p>The core of the test involved a ground station developed by Teravec Technologies in just three months. An <strong>infrared laser beam<\/strong> was precisely focused on the target despite atmospheric conditions and converted into electricity via specially designed <strong>photovoltaic cells<\/strong>. With the help of a parabolic mirror to focus the beam, the energy conversion efficiency reached approximately <strong>20%<\/strong>. In just <strong>30 seconds<\/strong>, over <strong>1 megajoule of energy was successfully transferred<\/strong>. To demonstrate the system&#8217;s performance, even some popcorn was popped during the experiment.<\/p>\n\n\n\n<p>The critical factor distinguishing this achievement from previous attempts was that the transmission was accomplished not only at high power but also over a long distance. To prevent the laser beam from being affected by atmospheric fluctuations, the system utilized <strong>adaptive optics and precise pointing mechanisms<\/strong>. Previously, a 400-watt laser had been operated for 12 hours over a 1-kilometer range. This time, DARPA prioritized <strong>range over duration<\/strong>.<\/p>\n\n\n\n<p>The first phase of the project has been completed at the White Sands Missile Range. Attention now turns to the second phase. By <strong>2027<\/strong>, the goal is to transmit <strong>10 kilowatts of energy over a distance of 200 kilometers<\/strong>. Furthermore, <strong>air-to-air energy transfer<\/strong> is also on the agenda. This could make it possible to send energy to remote bases, unmanned aerial vehicles, or isolated data centers.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p>What potential applications do you envision for this long-range wireless power transmission technology beyond military uses?<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">You Might Also Like;<\/h3>\n\n\n<ul class=\"wp-block-latest-posts__list wp-block-latest-posts\"><\/ul>","protected":false},"excerpt":{"rendered":"<p>Transmitting energy to a target kilometers away without the need for cables is no longer science fiction.
