What's "Three Gorges Dam In Space"?
Chinese scientists have announced a plan to build an enormous, 0.6 mile (1 kilometer) wide solar power station in space that will beam continuous energy back to Earth via microwaves.
The project, which will see its components lofted to a geostationary orbit above Earth using super-heavy rockets, has been dubbed "another Three Gorges Dam project above the Earth."
The Three Gorges Dam, located in the middle of the Yangtze river in central China, is the world's largest hydropower project and generates 100 billion kilowatt-hours of electricity each year. According to one NASA scientist, the dam is so large that, if completely filled, the mass of the water contained within would lengthen Earth's days by 0.06 microseconds. Source
However this news is all over internet for the past 6 or 7 days, it's nothing new. I've found a very same article on The Economics Times from 2015 which suggested the idea first floated in 1941 by fiction writer Isaac Asimov.
These articles made me look into Asimov's works and life a little more deeply. To my surprise, I found that Asimov was already very famous at the age of twenty one. He was writing Sci-fi stories for various magazines by that time and "The Nightfall" should be the story that is well in line with the idea of humanity running into darkness and how it could be saved. The story was so remarkable that in 1968 the Science Fiction Writers of America voted "Nightfall" the best science fiction short story ever written.1
I think most of us would accept that Isaac Asimov isn't only a fictional Sci-fi writer, he is the one whom you can trust for forecasts way beyond our imagination.
However this news about China's plans of creating a solar array in Earth's orbit, and implying that China would be the saviour of the humanity once were into an energy crisis doesn't make sense to me. Also the claims that China will build 0.6 mile strip of solar panels above earth and "the energy collected in one year would be equivalent to the total amount of oil that can be extracted from the Earth"2 seems to be more than an exegarration.
I think the media is just repeating this story to harvest the human interest in Asimov rather than in China.
So, this is just my rationale on this story and what I found.
I'm ready to listen your point of view on China or the repetitive circulation of this story in media.
Do you believe China has any such plans?
Do you think China has such technology to make it happen by 2028 as is claimed in the news?

If it’s China, it could honestly be anything. I remember reading an article about how the Three Gorges Dam actually slowed Earth’s rotation by a few microseconds. But 2028 feels way too soon for something major like that—expect something on that scale closer to 2032.

It wasn't completely true. Earth's rotation could only be slowed (0.06 ms) when the dam achieved its full capacity, which alone China isn't capable of doing.
BTW, you just read it above and remembered 🤣

I'm not saying you're wrong. I'm saying the calculation of filling the whole of "three gorges dam" is wrong.
Also, I've also mentioned the same above in the article. But you said you remembered.
Look at the para 3 from the article above.

Oh, I totally skipped that part! 😅

I just searched the web using some keywords I remembered and found that Snopes article.
Thanks, everything’s clear now!

Unless China has unlocked some critical electrical capabilities this isnt possible at least not now. There are electric transmission losses that prevent it as it currently stands. My Committee had a group pitch us this and it would have cost something like $400 billion at the most basic level and then over $1 trillion in the complete version.
A huge issue with both was the sheer cost to lift everything to space, maintaining, and most importantly repairing the station/power generator thing. It is going to get pummeled by micrometeorites and not only rapidly degrade but also its just physically hard to replace parts once you put them into place.

I recall this idea coming up during the Bush administration and all of those issues coming up then.
I'm sure we'll have something like this eventually (and probably before it actually makes sense), but I don't think we're particularly close to it at the moment.
reply
Would you agree that this piece of news is rather more inflated because of Asimov's idea than the actual plans if there are any?
reply
I don't know. That piece was new to me. I've read a lot of Asimov, but not that one.
I think it's a pretty natural idea that puts together a few different things that already exist.
reply
Well, this should be sent to these media publications who are just repeating these plans. It might well open their eyes. But the media doesn't care, all it cares is selling what is easily sold.
reply
Way too soon. 2038 might be more appropriate. Compare and contrast the space industry in China vs US. The US is nowhere near such a feat today, and neither is China.
Asimov's ideas are an inevitability however. This time I suspect a percentage of it will be funded by Bitcoin Miners, which Asimov did not predict.
