If your neighbor ordered a cluster of satellites to reflect directly on your observatory any time there's a clear sky, you'd probably do more than smile and give them a vegemite sandwich. I'm thinking that if the satellites aren't geosynchronous, there's pretty much no way this could work at all. You'd be shining all over the place all the time whenever you are transitioning from site to site and dumping a ton of propellent to keep rotating them for the minute or two they are over the target area. Even if it did somehow work, this would cause major issues for nighttime flight paths. Someone clearly didn't think about when something goes wrong and they blind someone driving a car, flying a plane, piloting a massive cargo ship, etc. resulting in crazy levels of damages. The company couldn't survive the legal/financial liability from that.
Reaction wheels and magnetorquers could handle attitude control without propellant, but then again you're just swapping the lifetime of your fuel tanks for the lifetime of the reaction wheels and electrical systems in general.

@@timetoriseindia5938 Depends on what they're willing to pay. The daily or weekly fee would get you an orbital origami deployed mirror reflecting the Sun towards your house. But paying for 10 years of that would qualify you for the special offer: tidally locking the Earth to the Sun, with your house at the center of the sunny hemisphere. Of course, if several clients request that, then it would have to be auction-based. Unless a very large number of clients appears, then turning the Earth into a ringworld would be the sensible option.
Funny. I work for non-profit trying to do something like this, but you won't be able to observe during the day. Sorry. th-cam.com/video/gFKeDHqb0qo/w-d-xo.html
Bill gates already is blocking out the sun with all the artificial clouds cus he don’t want anyone to eat anything especially if it’s healthy like all the veggies and fruit that rely on sunlight to grow he want to starve everyone and make it impossible to get vitamin D
Even if it was feasible, it would only accelerate climate change even further... we actually need to divert sunlight from Earth during the daytime, instead of the other way around.
The cost of a satellite launch (just the launch, not the cost of the device itself) is quoted to be anywhere between 50 to 400 million USD. For that money you could buy batteries with a power of 800 MWh, or a hundred wind turbines or a mix of the two..
I seriously feel like, this is the epitome of waste of human mind. That much efforts can be put on any of the n number of issues we currently have! 😂 Like they can use this same tech to terraform Mars! Thats even more understandable and meaningful.
@@teskaraka Exactly. How many humans? Only 0.000001% of the Earth's population (I made the numnber up) could go. Presumably those would be the wealthiest members of the human race, who could buy passage on the Mars-bound ship and a bed on the terraformed Mars. And those billionaires couldn't laze around playing golf, either. If they wanted to eat they'd need to grow food. Plus their wealth would vanish in the Earth's end-of-days scenario anyway. Like Dylan says: Everything is meaningless and we're all going to die.
Reminds me of the work of another Dylan "...Rage rage against the dying of the light. Though wise men at their end know dark is right." Apologies to Dylan Thomas.
As an astrophotographer it's a bad idea. But i'm more against it for the Wildlife. It's bad enough for them at the moment, with the heavily lit beaches in particular sending baby sea turtles in land rather than out to sea. What a terrible idea!
Can't imagine the revenue from the "power" generated at night could possibly be more than a minuscule fraction of the cost of lofting the needed hardware into space. Talk about a M87 size financial black hole. Saw a meme today that relates to the last ten word of your every video. Young kids were each asked "What scares you the most?" Paul said, "Werewolves." Nina said, "Sharks!" Dylan said "The unstoppable marching of time that is slowly guiding us all towards an inevitable death." Catherine said, "Dylan!"
It's worse than you think.. They claim that their "mirrors" will be 100m sq.. but it shines down a spot over a 5km sq area. So 100m capture spread over a 25,000,000m area. Which is 250x less energy dense. lol. Someone forgot to tell them about dissipation or dilution.. You can't spread a given amount of energy over a larger area and not expect the energy density to go down. smh
Well done for calling these thugs out and well researched Dylan. As soon as I saw their vid I knew it was fake because I also remembered that, apparently, their beam of sunlight according to their own claims should be 3 miles wide! But in this ad video, it's barely enough to lit up a chessboard lol. However if they are successful I'm willing to admit that could serve somewhat as proof that the earth is round...😊
Fair video. I agree with you. UNSW validated that the Earth’s radiant infrared heat can be used to generate electricity, even after the sun has set. I agree we should focus on solar panel innovation and not create more space junk.
It just fails on maths - the area of the mirror array has to be ~= the area of the PV array, otherwise you’re spreading out a tiny slice of sunlight over the target area like Vegemite on toast
Before I go on my rant, did you produce that audio in the end clip? So I did a little test playing around with a mirror and a flashlight. What I found is that when the flashlight was close to the mirror, the reflection was very bright, but when the flashlight was farther from the mirror, the reflection became wider and more dim. I think the only way this would work is if they had some sort of a focusing mirror that could narrow the light into a focused path. However, this in turn acts like a magnifying glass, and I think the focused energy would be very hot or dangerous to some degree. Further, this would have to be a huge mirror at epic scales in order to collect enough light to even be able to beam down. You would also lose a lot of light as it is coming down through the atmosphere. Maybe I don’t understand the physics all that well, but from what I can tell this whole project is unfeasible. I’m sure there is a way to calculate the efficiency, because you definitely lose light signal in a reflection, and the distance from the light source to the mirror, and the distance from the mirror to the redirection target, so many factors here that would contribute to a huge loss in efficiency.
Yeh that’s my intuition as well. The light from the sun comes from a massive area. The reflection comes from an (x)m surface. It’s orders of magnitude smaller! And yep just one of my older recordings :)
Here's an idea! Let's use large mylar mirrors to block light from hitting the Earth. If it were viable or practical, and I'm not saying it is, it would be much more constructive for humans to cool the Earth than warm it up with a lot of expensive orbital mirrors, beaming sunlight Earthward for the sake of energy generation.
I was so looking forward to sharing a smug comment about how the Russians tried this with Znamya and how I wrote the most devastating take-down of that project for my Astronomy degree dissertation back in 1998 (and thus credited myself with Znamya’s ultimate demise), but then you mentioned it. And that totally took the wind out of my sails…..
it's just simple math, you need an area reflecting larger than the panels you want illuminated (to compensate for mirror loss). so to illuminate a hectare (an 2.5 acre for the weird unit club) of solar panels to generate electricity you need a 90% reflective mirror of 1.1 Ha (2.75 ac) (adjust up for each % of non reflectiveness), and you need to have enought reaction mass to turn that mirror to track that point on earth for hours each day.
I do like the idea of space based solar energy, and i think it could be truly revolutionary. However, getting that energy to ground leaves a lot of question marks, even if that ground is 5000 meters up. Laser beams would make far more sense than scattered light. There have been a number of science papers on very thin film-like solar panels --- although I have no idea if such panels could survive harshness of space and requirements for toughening and cost of placement. What makes most sense to me is not crowded LEO, but graveyard orbit to harvest solar power. Beaming laser power up and out is simpler than downward to earth, heck even to power moon settlements, but sadly economically that makes no sense at the moment. Another concept could be to beam power down to satellites that are using hall effect thrusters that fly around the strato or mesosphere instead of traditional stationkeeping. Of course, a hot air balloon can be a test of stratosphere based panels as a university study, with added bonus of easy retrieval and low cost. Just ideas, but alas some scholar would have to write detailed feasibility papers about all the above (and more).
The accuracy those satellites would need. The distance between them and the ground means if it was off by even a micrometer it would shine in a different location completely. Total scam. Not to mention the stability, i.e., shaking and rotation. I'm sure there's other factors I'm missing but these come to mind first.
Exactly it would create more problems than solving any . 1)Large telescopes for observing space would make errors in detecting asteroids 2) it might make earth's atmosphere warmer 3) may create problem of debris for future space exploration projects cuz 1 shattered glass of mirror is pretty much big cloud of debris
Then invest them thats what they want cuz it isnt sustainable at all . Why would u need sunlight at night or somewhere where is less light?? Either for solar energy or some sort of agriculture i dont kow anywhere else u need it. Cost it would take to place and maintain that mirror placed with satellite wont match the requirement it solves. We have communication satellites sustainable cuz we got many users in every household that gets luxury of wireless,quick and cost effective communication what those mirrors cam give?? Its woke idea
Why not just generate energy from moonlight? Probably not a lot less bright. Better still use one of those NASA Sun Simulators that they use to fake a 24hr sun I Antarctica 😂
In the book 2001, Jupiter gets transformed into a mini-sun by the monolith reproducing and increasing the planet's density, thus screwing up astronomy on earth for over half the year. Old idea. Human's battle against darkness.
Just scaring up some of that sweet, sweet venture capital money, like with flying cars, self-driving cars, block chain, AI, all crap. Anyway, just doing simple physics we know from doing astronomy, light intensity falls off as a square of the distance, there is no mirror that will reflect enough light to power anything.
A prayer wheel, mood ring and/or ouija board may contribute to the instrinsic value of the company or at least shine a light on the long term potential of the idea (queue the long groan for this terrible pun).
Great video! However, the solar power industry is hardly in its infancy. Here in California, we now have too many solar panels. Sounds unbelievable, but that’s what years of favorable policies have done! And now, too much of a good thing can actually be bad. Without proper grid support (to send that energy to other places that may not be able to generate so much power) or enormous storage capacity, a lot of solar power ends up being wasted, every single day. So, the real challenge, which I wish companies were focusing on, are 1) expanding the grid, 2) developing more storage capacity, and 3) smart homes, to automatically use more power when excess power is available (for example, to charge a car during the day). This crazy idea of reflecting sunlight from space is just that: a crazy idea. Clear skies down under!
The US and Russia have already demonstrated it is relatively easy and cheap to destroy satellites, much less a big mirror in the sky. There are many ways to weaponize satellites, mirrors are not one of them.
Well, think of how that would mess up all your nocturnal animals. There are many reasons this is a bad idea. Better to develop a world wide distribution grid than this thing. And I'm not saying that would be a good or doable idea!
the cost of throwing mirrors into space (and keeping it there) is never going to be better than the minor bit of energy you'd get back from it.. put that cost into panel-fields on earth or wind farms and you'd probably be able to power the world instead of lighting up a 5km circle with some moonlight considering a 50-400million launch cost of a satellite.. considering that the Hubble costs 90 million dollars a year to run.. ISS 3 billion a year.. most telecom satellites 1.5milllion a year.. lets call it 1 billion to develop this. then lets lowball 200 million just to get it into orbit given the size of it.. lets low-ball 100 million a year to run, probably more with the amount of control it needs. - you're looking at 2.2bil already over 10 years. probably way more cost of building a 1 megawatt solar farm is 900.000-1.3mil. so 2.2bil would get you a 2200megawatt solar farm... I highly doubt that some reflecting light at moon strength will come near to that And how will you control it? how are you putting a satellite in spot long enough for sunlight to be reflected to one spot? what if multiple people order sunlight? I mean, the ISS does a full rotation in like 90 minutes, at most you might get 10 minutes where it's in "your sky", horizon to horizon.. what is 10 minutes of light going to do? it's not going to be enough to make a dent in solar panels.. 99% of the time it will not be anywhere near you, or it would cost too much to get it near you... except if you put hundreds of geosynchronous satellites up there, but then costs are going to be WAY more and exceed the point even further.... How much are you paying for 10 minutes of sunlight? I'm guessing it will cost more than the energy you'd get from it..
i pondered this idea when i was in high school, i assume new excited humans are pondering this idea and some think they can make a buck too. how long will it take his bitcoin attitude to realize that he can't publish a single paper about his load of fantasy.
Sounds like nonsense. Furthermore earth needs night time. Trees and plant life release their oxygen at night. I see it all the time when I check NEXLAB Satellite and Radar at night.
What if it would happen / work and it extremely potent, what would then happen if we start putting energy into the cold phase of the earth? I think the project is pretty cool tho, even if i don't want it :P
You somewhat lost credibility when you tried to discredit the founder credentials. SpaceX does not hire unpaid interns, and interns at SpaceX perform the exact same duties as full time employees. Also for the record I think this company is really stupid.

they'll just focus the sunlight into a strong beam and vaporize the clouds away 👍
And that also doesnt heat up those clouds

This crazy idea of reflecting sunlight from space is just that: a crazy idea. Clear skies down under!
The bigger threat is this being weaponised. Imagine burning an entire city just using concentrated sunlight through a set of mirrors and lenses.
The US and Russia have already demonstrated it is relatively easy and cheap to destroy satellites, much less a big mirror in the sky. There are many ways to weaponize satellites, mirrors are not one of them.
Let night be night.
“Finishing” that degree may not be the same as “completing” his degree.
Just saying
An obvious scam tbh
Obvious to backyard astronomers maybe. Tech journos are eating it up.
could I order some romantic moonlight during the day?? 😎

Well, think of how that would mess up all your nocturnal animals. There are many reasons this is a bad idea. Better to develop a world wide distribution grid than this thing. And I'm not saying that would be a good or doable idea!
the cost of throwing mirrors into space (and keeping it there) is never going to be better than the minor bit of energy you'd get back from it.. put that cost into panel-fields on earth or wind farms and you'd probably be able to power the world instead of lighting up a 5km circle with some moonlight
considering a 50-400million launch cost of a satellite.. considering that the Hubble costs 90 million dollars a year to run.. ISS 3 billion a year.. most telecom satellites 1.5milllion a year..
lets call it 1 billion to develop this. then lets lowball 200 million just to get it into orbit given the size of it.. lets low-ball 100 million a year to run, probably more with the amount of control it needs. - you're looking at 2.2bil already over 10 years. probably way more
cost of building a 1 megawatt solar farm is 900.000-1.3mil. so 2.2bil would get you a 2200megawatt solar farm... I highly doubt that some reflecting light at moon strength will come near to that
And how will you control it? how are you putting a satellite in spot long enough for sunlight to be reflected to one spot? what if multiple people order sunlight? I mean, the ISS does a full rotation in like 90 minutes, at most you might get 10 minutes where it's in "your sky", horizon to horizon.. what is 10 minutes of light going to do? it's not going to be enough to make a dent in solar panels.. 99% of the time it will not be anywhere near you, or it would cost too much to get it near you... except if you put hundreds of geosynchronous satellites up there, but then costs are going to be WAY more and exceed the point even further....
How much are you paying for 10 minutes of sunlight? I'm guessing it will cost more than the energy you'd get from it..
i pondered this idea when i was in high school, i assume new excited humans are pondering this idea and some think they can make a buck too.
how long will it take his bitcoin attitude to realize that he can't publish a single paper about his load of fantasy.
Wonder what it would do for climate change?
This only works if physics doesn't exist which basically means nothing exist 😂😂
You looks like Zack from Zack King!!
Haha read your comment to my son Zach and he laughed
This is just a ridiculous idea lol
this vaporware idea does not have merit. use those money resources for geothermal like facebook is doing.
Sounds like nonsense. Furthermore earth needs night time. Trees and plant life release their oxygen at night. I see it all the time when I check NEXLAB Satellite and Radar at night.
Bhai kuch information dene se pehle check kia karro ki wo sahi bhi ha ke nahi😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡
Bröther - before posting a comment about incorrect information make sure you cite the information with your correction.
first
What if it would happen / work and it extremely potent, what would then happen if we start putting energy into the cold phase of the earth? I think the project is pretty cool tho, even if i don't want it :P
Funnn
You somewhat lost credibility when you tried to discredit the founder credentials. SpaceX does not hire unpaid interns, and interns at SpaceX perform the exact same duties as full time employees. Also for the record I think this company is really stupid.
Fair :)
This is a scam, not real at all
is that type of engineering and business idea that makes you sign up with Mao's ideas of how to deal with exploitative entrepreneurs
Its so dumb and stupid idea 😅😅😅
