The concept of space-based solar energy was been tossed about by science fiction writers for greater than a century, however has turn out to be the subject of great dialogue solely up to now few years. It’s a type of ideas that appears to make excellent sense on the macro degree.
Photo voltaic power is free. The solar sends us sufficient of it each hour to energy all of humanity’s wants — sure, even AI — for a yr. However the Earth rotates because it revolves across the solar, which suggests each place on Earth is in darkness for a portion on day-after-day. (Sure, I do know there are locations close to the poles the place the solar shines constantly for a portion of yearly, however they aren’t main inhabitants facilities. Work with me right here.)
In a single state of affairs, people might construct excessive voltage transmission strains to move solar-generated electrical energy from the sunny components to the components in darkness, however when you assume the Strait of Hormuz is a choke level, think about how susceptible these transmission strains can be if some lunatic in energy wherever on the earth determined to blow them up. Assume that’s far fetched? Actually? Have you ever learn the headlines this morning?
A New Take On House-Primarily based Photo voltaic
Many assume a greater concept is to place photo voltaic collectors into orbit across the Earth which can be excessive sufficient to all the time be in daylight. They might accumulate all that beautiful photo voltaic power and beam it again to Earth 24 hours a day. Consider it. No extra thermal era powered by nukes, oil, coal, methane, wooden, biomass, or unicorn farts. What an exquisite world it will be. What a wonderful time to be free!
Ling Xin is a science journalist primarily based in Ohio who covers physics, astronomy, and area. Her writing has appeared in Science, Scientific American, and MIT Expertise Evaluation. In a narrative for South China Morning Submit dated April 5, 2026, she writes {that a} senior Chinese language scientist has outlined the potential navy functions of space-based solar energy know-how. His proposal gives a glimpse into how power beamed from orbit might additionally help surveillance and digital warfare.
(Sure we all know SCMP is a part of the Chinese language military-industrial advanced and its tales needs to be taken with a grain of salt. In that respect, it’s a lot like Fake Information, so recover from your “holier than thou” angle.)
In a paper printed within the journal Scientia Sinica Informationis, Duan Baoyan, a number one architect of China’s Zhuri area solar energy initiative, wrote that his workforce had revamped the design of the enormous orbital infrastructure. Now, along with power transmission, the brand new system was might help a variety of duties “akin to communication, navigation, reconnaissance, interference and distant management,” he mentioned.
Duan is presently a professor of electromechanical engineering at Xidian College in Xian and an academician of the Chinese language Academy of Engineering. In his proposal, he confused the necessity for very slim, exactly steerable microwave beams to ship power from area to the bottom over lengthy distances.
The brand new design enhance the effectivity and accuracy of wi-fi energy transmission. That’s the excellent news, However it is also able to focused sign transmission, which might help functions akin to jamming navy communications. That’s the dangerous information.
24-Hour Photo voltaic

China is without doubt one of the world’s main international locations growing space-based solar energy. In contrast to photo voltaic panels on the bottom, that are restricted by climate, seasons and the day-night cycle, space-based methods can accumulate daylight virtually constantly.
Greater than a decade in the past, Duan and his colleagues proposed the so-called OMEGA — Orbit M-shaped Exploration and Gigawatt Utility — design as one among China’s fundamental approaches to constructing such a system. In 2022, the workforce accomplished a 75-meter (265-feet) ground-based facility to check the complete course of, from monitoring the solar and concentrating mild, to transmitting power wirelessly and receiving it at a distance.
Within the newest paper, Duan focused on making OMEGA a part of the broader Zhuri — or “sun-chasing ” — initiative. Doing so would make the system extra sensible by shifting from a single massive construction to a modular system made up of many smaller models working collectively.
As a substitute of counting on one huge energy station, the distributed design would group a number of photo voltaic amassing models into modules and arrays, permitting the system to proceed working even when some parts failed. (Or received taken out by some hostile energy.)
The strategy can also be supposed to cut back the engineering challenges of dealing with extraordinarily excessive energy ranges in area and decrease the general problem of constructing the system, in keeping with the paper. Duan mentioned the OMEGA design might supply benefits over ALPHA, together with a a lot less complicated construction, extra environment friendly power assortment, and improved thermal administration.
NASA SPS-ALPHA

The idea is just not new. 15 years in the past, NASA advocated for its SPS-ALPHA — Photo voltaic Energy Satellite tv for pc through Arbitrarily Giant Phased Array — idea that relied on coordinating huge numbers of small modular models to generate and transmit energy.
In 2023, researchers on the California Institute of Expertise demonstrated microwave energy transmission in orbit. First proposed within the Nineteen Sixties, the area solar energy idea has lengthy been seen as a possible approach to offer massive scale steady clear power, though technical and value challenges stay. That’s what passes within the scientific neighborhood for understatement.
After all, China is just not the one nation toying with the concept of space-based weaponry. The attract of blasting individuals and issues on the bottom from area is actually interesting. What could possibly be nearer to a divine energy than sending a beam of lethal power down on an unsuspecting immigrant enemy? ZOT! A a method ticket to hell with believable deniability built-in. Absolutely Jesus would approve!
Interrupting Crucial Communications
Final yr presently, Chatham Home, a world coverage advisory group primarily based in London, mentioned in a report, “The rising reliance on space-based belongings for navy and civilian features has heightened the necessity to shield these methods from cyberthreats.”
“Satellites play an important function in safe communications, navigation, intelligence and early warning methods, making them indispensable to NATO’s defence and deterrence posture. Nonetheless, space-based belongings face a rising array of threats, together with cyberattacks, which might disrupt essential features, compromise operations and undermine world safety.”
The crux of the matter is, whose cyber capabilities are deemed pleasant and whose are deemed hostile? The StarLink system from SpaceX has been used to help Ukrainian makes an attempt to defend itself from Russian aggression — besides throughout occasions when Elon Musk awakened in a bitter temper and turned off entry to the system over Ukraine. Does anybody assume Musk ought to have management over strategic communications?
The upshot of all this deal with space-based energy and communications dangers flooding the skies above the Earth with so many satellites that the one approach mere mortals will be capable to see the celebrities is in AI generated simulations.
Each device might be each a boon and a bane. G. Gordon Liddy mentioned he knew 12 methods to kill somebody with a No. 2 pencil. House-based energy might certainly be a profit to humanity, or it might rework right into a weapon extra highly effective than any nuclear bomb. The limiting issue is how rational the individuals controlling such methods are. As we speak there’s little cause to be optimistic on that topic.
