  • Tiangong expected to play a key role in China’s space solar power station project by providing a testing platform for high-voltage electric devices

  • Space power station could point beam to almost any location, making it an ideal to power military equipment or remote outposts, says project team

China’s space station will join a controversial project to collect solar power from space and send it to Earth in a high-energy microwave beam, according to a senior scientist.

The Chinese space station Tiangong – which means “heavenly palace” – became fully operational when the last major service module, Mengtian, docked this month.

Some space scientists have suggested Tiangong – the largest infrastructure in orbit owned and run exclusively by a single country at present – can change the pace or direction of the space race.

Yang Hong, chief designer of the space station, told a conference in Wenchang, Hainan, on Tuesday that Tiangong would play a key role in China’s space solar power station (SSPS) project by providing a testing platform for high-voltage electric devices and in helping assemble ultra-large structures.

In a lecture at the conference attended by space scientists and engineers from around the world, Yang said the space station had the resources and capability to do demonstrations, “verify key technologies, accelerate technological breakthroughs and accumulate in-orbit experimental data” for the SSPS project.

He said these would help China meet its peak carbon and carbon neutral goals.

A paper published by the project team in the journal Chinese Space Science and Technology in June reported that the full-sized Chinese space solar power plant would be a 1km-wide structure beaming gigawatt-power microwaves to Earth from a distance of 36,000km (22,4000 miles).

Unlike traditional solar farms that work only during the day, the space-based solar array would collect and transmit energy 24 hours a day, it said.

The microwave beams could penetrate clouds and be picked up by an antenna on the ground to generate electricity.

Operating in the geostationary orbit, the space power station could direct the beam to almost any location, making it an ideal candidate to power military equipment or remote outposts, the team said. However, some researchers have also speculated that the beam could be used as a weapon.

The European Union and many countries, including Japan, Britain and the United States, have launched research programmes to develop similar technologies.

But there is debate in the scientific community around whether the microwave beams will damage communications, human health or the environment.

Yang said the Chinese space station would get involved in a number of critical experiments to bring the space power plant from science fiction to reality. Some external portals on the station were designed to have high-powered electrical equipment plugged in, he said.

However, the generation of a strong electric current and conversion to microwaves will produce excessive heat and many other problems, which are not easy to solve in the space environment.

The space station is an ideal platform for China to evaluate the long-term performance of the new technology and equipment in orbit, Yang said.

The Chinese space scientists also plan to use cargo ships – which are usually left to burn in the atmosphere after a mission – as a basic component to build the solar power plant. Using several robotic arms, Tiangong could join up a number of cargo ships and some extra solar panel units to create a prototype power plant.

This mini power plant, after rising to an orbit 100km above the space station with ion thrusters for safety, would conduct experiments to verify technologies for the full-scale plant, including microwave energy transmission and powering up an allied satellite with a high-energy laser beam, according to a slide show Yang presented to the conference.

China plans to conduct the first space-to-Earth energy transmission experiment over the next few years. A small space power plant that can supply electricity to remote military outposts will be up and running by the 2030s, while commercial power generation is expected to start in the 2050s.

The US Air Force also plans to launch a solar-powered satellite in 2025 that will be capable of producing and sending focused microwave beams from near-Earth orbit.

Some studies have suggested that the microwaves – mostly in the same frequency range as those used by a Wi-fi router – will be safe for humans unless a person stepped into a receiving area.

But how to keep the energy beam aimed at a precise spot on Earth over a distance of tens of thousands of kilometres remains a major challenge, according to scientists involved in these projects.

Some researchers also warned that persistent, intense energy transmission between space and Earth could cause disturbances in the ionosphere that could lead to unexpected impacts on the Earth’s environment.

Those are surface to space. Not space based as far as I'm aware. This is potentially a weapon that can strike from orbit, if it can deliver enough concentrated power at a specific location.

Just did the math.

A 1 gigawatt, 1km wide beam will output 0.12 watts per centimeter squared (in a vacuum).

So it would be a couple of watts worth of power hitting you in the head at most (5-ish watts) . Hardly a weapon.

Your microwave oven in your kitchen is likely over 1000 watts.

How will they avoid any other satellites, Aircraft, or Avian creatures from getting Damaged, or harmed from this energy beam if the fly thru its path. and how will it work moving thru atmospheric clouds, rainstorms or hurricanes.

those are like guidelines and as long as the weapons are for "science" not war then it's fair game. we have a few weaponized up there ourselves, for "science" of course.

plus i think the beam will be indistinguishable to the average human at the power level in the article. so not scary space lasers

darkshark9 t1_ixnedgj wrote

You can use longer wavelength microwaves that essentially render the atmosphere transparent in terms of losses. So even a 1gw beam would barely lose anything if the right wavelength is chosen. So it wouldn't affect the atmosphere in any relevant manner.

Don’t forget you have to have some sort of beam focusing to make sure it hits the target right. If you can focus it a little you can focus it a lot. Instead of 1GW over a 1km^2 you get 1 he over 1m^2

And thats assuming the exact frequency of microwaves that resonates with water molecules. Which obviously wouldn't be being used. Were basically just talking about a high power radio transmitter.

Sounded to me like the satellite structure is going to be 1km wide. The microwave beam can be insanely narrow if they want it to be… wonder if they will be able to focus it, which really would be weapon territory if they can focus it small enough.

For its supposed intent, I could imagine making some sort of ground antenna array over a large area. The larger the area, the safer it would be for personnel to maintain the infrastructure. Being China… maybe they don’t give a f#ck, and will just make the slaves maintain some small antenna and have fewer losses in collection.

Tinfoil hat is not enough, though… it’s an intriguing idea yet…probably a SHIT idea.

The laws of physics won't let us focus a beam that tightly over that distance due to its diffraction limit.

Shine a laser at the moon and the beam spot is like 50km wide by the time it reaches it.

It is top secret, but the US already has space-borne nukes. I learned this from a person I know and trust who should NOT have told me. That this is denied and that no other nation on Earth has criticized the US for violating this treaty likely indicates that other nations are in defiance as well.

You know its a very specific frequency of microwave energy that is used in a microwave oven, all other frequencies are completely harmless. Even if that exact frequency was used, then in that case i doubt it would penetrate far through the atmosphere, there is a lot of water in the atmosphere you see.

Honestly, this sub ought to be renamed "scifi" rather than futurology for all the understanding of basic science that most of its members seem to have.

Sim City 2000 and Death Star jokes aside, I assume in real life it would be trivially easy to avoid accidents by shutting down the beam if it goes off target and it would be fairly ineffective as a weapon, since it would be a very expensive sitting duck that could never get off more than one shot.

If it could be made to work it would be very useful, but quite challenging technically.

Also someone will complain about the occasional bird getting fried, like they do with wind power.

Sadly, that's a little heavy on the severity of a claim, and a little low on the backing up of that claim. Not to say that I don't expect the major powers to have space based satellite interception at the very least by now. That recent "secret military" payload on the Falcon Heavy for example... wouldn't be surprised if that was something like that.

PussyMassage t1_ixrdq5y wrote

I could never conceivably back up this claim, and if I could, it would mean I was involved in espionage. I don't know this to be true for certain, but again, I was told this directly by a person I know to be trustworthy, who would have reason to know, and who made a very grave error in telling me. It is, however, such juicy information that flies in the face of what folks "know to be true" that I feel like it's my duty and honor to expose this information.

If folks want to believe our national security is dependent on ICBMs, sub-launched missiles, or airborne bombers alone, that's fine. However, there are already nuclear warheads deployed in space.
