Welcome to this week’s installment of The Intelligence Brief… with the recent announcement by the Naval Research Laboratory that its innovative Space Wireless Energy Laser Link (SWELL) will soon embark on its early testing phase, this week we’ll be analyzing 1) the NRL’s SWELL experiment announcement, 2) what laser power beaming technology could help facilitate for future space missions, and 3) the benefits of wireless energy transfer both in space and on Earth.
“The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of the planter – for the future. His duty is to lay the foundation for those who are to come, and point the way.”
Podcasts: This week in podcasts from The Debrief, Stephanie Gerk and MJ Banias ask whether organoids dream of electric bandages and other mind-bending possibilities in the latest installment of The Debrief Weekly Report. Meanwhile over on The Micah Hanks Program this week, I spoke with Colorado Parks and Wildlife Northwest Regional Manager Travis Black for an in-depth look into the the potential causes behind Colorado’s mysterious cattle deaths last year.

With that all behind us, it’s time to shift our focus over to the Naval Research Lab’s quest to bring wireless energy lasers into fruition for space missions, as well as for Earth-based applications.
A Wireless Energy Laser Heads Into Orbit
This week, the United States Naval Research Lab (NRL) announced its plans to deploy a new system that will allow it to use lasers to beam power in space.
The Space Wireless Energy Laser Link, or SWELL, will see its first demonstration in conjunction with a scheduled Pentagon Space Test Program H9 mission to the International Space Station which launched on March 15, according to an NRL news release.
“SWELL is one of several experiments that will launch aboard the SpaceX Dragon cargo vehicle to the ISS for the yearlong mission to collect data during a laser power beaming link in space conditions,” The NRL statement said.
Power Beaming Possibilities
Sponsored by the Office of the Under Secretary of Defense for Acquisition & Sustainment (OUSD (A&S)), the innovative power-beaming experiment will attempt to gauge the viability of using technology to beam power in space using lasers for various space missions and other applications, while also exploring ways the technology might also be useful in fighting energy-related problems on Earth.
The project has seen additional support from the Operational Energy Capability Improvement Fund (OECIF).
Paul Jaffe, Ph.D., SWELL’s Principal Investigator, called the initial rollout of the technology a “modest experiment,” but one which will allow the NRL to focus on ways the technology can be developed and used both for optimal power development and also to do so efficiently across the distances required for space.
“By employing laser transmitters and photovoltaic receivers,” Jaffe said, “power beaming links will be established that will pave the way for rapid, resilient, and flexible energy delivery systems.”
Energy Delivery through Laser Power Beaming
Using electromagnetic waves to deliver energy is beneficial for many reasons, primarily on account of the capability to transfer it almost instantaneously, as there isn’t any requirement for carrying mass.
According to project leaders, laser power beaming could become crucial in terms of being able to power future space missions, and the NRL’s current experiments aim to help facilitate that.
SWELL Program Manager Chris DePuma said the technology is “poised as a critical enabler for power distribution on the moon and elsewhere in space,” calling the demonstration the “next step” in bringing power beaming into use both for future space missions and also for applications on Earth.
Year One and Future Applications
Over the course of the next year, the initial SWELL experiment will allow NRL scientists to collect vital information on the performance of the technology’s hardware while in orbit, allowing the team to gauge the limits of its use in future operations.
One of the key benefits of the technology is that it will one day reduce the payloads required for launches by removing the necessity for carrying energy sources like fuel and batteries, as well as cables and wiring used to transfer energy in traditional electronics, thereby allowing additional space for other resources that future space mission will require.
In an NRL statement, Jaffe said that laser power beaming technologies like SWELL could perform similar functions on the ground, allowing the distribution of power in more efficient ways, and even may one day allow power collected from solar arrays in orbit to be sent back to Earth.
“SWELL is the next step into this new frontier,” Jaffe said.
Funded by the Defense Advanced Research Projects Agency (DARPA), the folks at Electric Sky are moving closer to revolutionizing electric aviation by making its Whisper Beam power-beaming system a reality.
The “Dark Ages of the Universe” will be the focus of a new experiment conducted jointly by NASA and the U.S. Department of Energy (DOE), involving the placement of a new science observatory on the far side of the Moon.
