Wireless Electricity: US Navy Used Microwave Beams to transmit Energy

The U.S. Naval Research Laboratory recently announced that it successfully tested ground-to-ground microwave wireless telex technology in Maryland, transmitting 1.6 kilowatts of power within 1 km, making it the longest wireless telex test in history.

Microwave Power Beaming, first proposed in the 1890s by Nikola Tesla, who built the first wireless teletype tests in Colorado Springs and Long Island, New York in the 1900s The tower, but at the time due to lack of effective technology, was later cancelled due to lack of funds.

It wasn’t until the 2010s that wireless teletype technology began to make more progress in the space environment, and the Japan Aerospace Exploration Agency (JAXA) and Mitsubishi Heavy Industries completed the first ground-to-ground test in 2015, when transmitting about 55 meters within 55 meters. At 1.8 kilowatts, it was the farthest and most energetic experiment ever.

The U.S. Naval Research Laboratory (NRL) is funded through the Pentagon’s Action Energy Research Improvement Program Fund and chaired by Dr. Christopher Rodenbeck of the NRL’s Advanced Concept Group.

NRL spent 12 months building ground-based wireless teleportation equipment and recently successfully tested the use of 10 at US. Army Research Field Blossom Point, Maryland, and at MIT. GHz microwave, transmits 1.6 kilowatts of electricity to a receiver 1 km away.

Dr. Rodenbeck pointed out that this test successfully set a new record for wireless telex technology, and during the research period, choosing how much bandwidth microwaves was the biggest challenge, because the larger the bandwidth, the rate at which it is lost in the atmosphere with distance. higher, and research results show that 10GHz is an appropriate choice.

This time, the distance record of wireless telex technology has been successfully refreshed, and it is one step closer to the ideal goal of wireless telex back to Earth. Significantly solve the problems of pollution and lack of raw materials in existing power generation methods.


An ancient invention

Concretely, the military installed a 10 GHz microwave beam designed as part of the Scope-M project, in two places. The first was in Blossom Point, Maryland, and the second was in Massachusetts. 

This 10 GHz frequency was chosen because it remains stable even in the event of heavy rain and does not disturb the environment. In the end, the beam worked with 60% efficiency, which is very creditable for a technology that left army scientists wondering.


With this process, according to the researchers, it would be possible to create supply points without an electricity grid on Earth from orbital solar power plants . But the army intends instead to use it to directly transmit energy to troops in the field to avoid supply constraints. 

One can also imagine that this energy could be used to power the famous defensive laser cannons that the US Navy is currently testing and, why not, very energy-intensive railguns . The principle of wireless energy distribution over long distances and far from new. By the 1970s, the technology was on point.
