US Air Force Hopes to Collect Solar Energy in Space, Beam It to Earth BY ISABEL VAN BRUGEN May 31, 2021 Updated: May 31, 2021

The U.S. Air Force (USAF) is working on harvesting solar energy in space and beaming it back to Earth to address the energy demand of its military personnel deployed at remote bases.

The project, named the Space Solar Power Incremental Demonstrations and Research Project (SSPIDR), will allow solar energy to be harvested and beamed back to the Earth via an outpost, irrespective of the latitude, longitude, climate, time, and other factors.

The U.S. Air Force Research Laboratory (AFRL) shared a video on YouTubeexplaining how the project could one day revolutionize energy use on Earth for military personnel and one day, civilians.

An Arachne satellite would be used to collect and convert solar energy to radio frequency, which would then be beamed to a receiving station on Earth. The receiving antenna, called a rectifying antenna or “rectenna,” would convert the radio frequency into usable power for the end user.

That power could be used to fuel power generators at remote bases and weapons. AFRL’s main mission, it says, is to develop and mature technologies to “benefit the warfighter.”

“Ensuring that a forward operating base maintains reliable power is one of the most dangerous parts of military ground operations. Convoys and supply lines are a major target for adversaries,” the narrator of the AFRL video states.

“To utilize the solar power beaming system, a service member would simply set up a rectenna to gain access to power, eliminating costly and dangerous convoys,” AFRL’s website notes. “Essentially, AFRL is enabling the relocation of those supply lines to space, which could save countless lives.”

AFRL on its website adds that there is a “high possibility” that this technology could also be a highly valued asset in the commercial sector.

“Much like the Global Positioning System (GPS), which started out as a military asset and transitioned to a technology now used by people everywhere, this solar power beaming system could transition to broader usage, providing solar energy regardless of weather, time of day, or latitude,” it says.

Col. Eric Felt, head of the Space Vehicles Directorate, told the Journal that over the next decade, the potentially “game-changing” technology could become more widely available.

“The technology has reached a point where we believe we can do it,” Felt said. “We’re in the final maturation phase for the key technologies, and we’ve got a road map for it … We’ve laid out the whole program, and we’re now on a path to build a 2-meter solar system for launch on a satellite in 2023 to prove the technology.”

An X1 solar flare occurred a few hrs. ago. A CME launched directly at Earth.
A serious opportunity to "diagnose" magnetosphere strength.

For possible comparisons -
The Kp index reached 7 back on 3/6/2016 producing aurora seen across England.

On 11/8/2004 it hit 8.7.
