    Amazing idea. Too bad it won’t happen and the panels will probably be in the sand a day after being installed

    One of my professor posted a similar question in test where we had to calculate the area of panels needed to power the entire USA. The references I used showed me that the best solar panels in market produce electricity at about 20% efficiency, which is 10 times better than what nature has achieved by photosynthesis, but nowhere close to your assumption of 100% that you made in this video.

    • Blaž Winkler

      @Stettafire There is a cool article called "solar cell efficiency" on wikipedia that nicely sumarizes the problem!

    • abed marachli
      abed marachli 8 days ago

      I think his words are true, but you did not understand the idea, that the efficiency of 20% is the amount of benefit from photosynthesis in kilowatts per square meter. The company calculated it and gave you the figure of 350 watts, and now they have reached 650 watts and more in some countries.
      What I want to say, if the benefit was 100%, I would have taken a kilowatt and more per square meter of land

    • Filipe Barroqueiro

  • Evelynne Leanán

    This is an amazing idea. A few problems I can see happening is if sand covered the solar panels, so they would have to be elevated very high. As well as a project of large scale would sky rocket the minerals and other materials needed, and would the intense heat damage them? As well as where would the waste after the solar panels exceed their useable lifespan? And would the amount of energy redirected into the atmosphere damage the ozone layer or escalate the climate crisis? The idea of covering a bit of the Sahara is still an amazing idea, and let’s be honest, has a lot less problems that we need to find solutions for then the issues surrounded oil and gas.

      Not only this, but just think what will happen to the closest living places to Sahara(like South Europe, Middle Afrika and Middle East for example). Wouldn´t all this heat cause the whole climate in this regions to change a lot. Like making them all into some deserts after time or atleast increase the normal temperatures by 10 or more degrease. I don´t believe this thing can happen without damaging the nature and climate around.

  • PoptheBubble ChartLeaks

    It sounds like a huge fire risk. Will they have their own fire department? I like the thought experiment. It feels more workable to create a permaculture solution on the perimeters which include some solar panels. Then maybe we could expand the great green wall a bit. Also, given the wind in the Sahara, wouldn't it make sense to mix solar closer to towns with wind turbines that could reach above sand storms farther into the desert?

      @Sam Rooney nuclear energi also takes big resources mind you. As fare at the impractical goes i am sure it can be done with some inavations like auto cleaning the solar cells and if big solar plans where made it would mean the price of solar cells would go down because of compation in making them.

  • Miguel Rivera
    Miguel Rivera 5 months ago +1

    What if we installed these panels with the environment in mind as well? For example: Install them at the same height as would a normal tree would be several tens of meters above the surface to as to create many canopies that could also provide shade for those native to the areas. Also, leave enough gap space between panel arrays to let some sun pass between them in the "off chance" it could be used for other purposes. Think about it. You could create an artificial "forest" of panels. even design them with the aesthetics in mind (leaf shaped and such). Just a thought.

  • John Snowshoe
    John Snowshoe 8 months ago +2

    One of the things to keep in mind is that yes, the solar panels are not 100% and may only be around 25-35%. However, considering they could supply additional energy and reduce the strain on the other energy sources...it's still a win.

  • Almighty YT Algorithm
    Almighty YT Algorithm 6 months ago +6

    Considering the lighter colour of the desert sand acts as a light reflector similar to ice caps (albeit sand absorbs a bit more sunlight than ice caps), if we covered all of it with darker panels meant to absorb the sunlight, then this would likely also affect global temperature considering how large the sahara is

  • R.E.D_Knight
    R.E.D_Knight 5 months ago +3

    Well actually if the cleaning is fully automatic it's actually possible, hear me out: if you put a sort of air duster over the solar panels, put a sensor over each solar panel so if sand blocks the solar panel, the system will detect it and will clean the solar panel if the machine bugs than just use manual labor to repair it.

    Very thought-provoking video. Thank you for all the effort. You might not spend anywhere close to the 60+ trillion you estimate for the NM-sized array IF you build a network of manufacturing and maintenance facilities locally. Of course, you raise many other good points to consider later in your analysis. Thanks again.

  • doja boja
    doja boja 7 months ago +3

    this is an amazing idea with great intent. how about we do this but in isolated places in cities of tropical countries? designing and building the panels as well as management will provide livelihood to many citizens. in the first few years after it finished development towards being an alternative source of energy, it will for sure be more expensive than the more common ones. however, it is a start, and if the idea of it expands, we could actually make something good from something that is already existing. too bad people who have enough money to start on the project are more often than not only thinking about how they can make money out of it.

  • _nljh
    _nljh 6 months ago +3

    Might be a great green energy solution but still has an incredibly high impact. Requires manufactering at large scale (emissions), transporting (emissions) and placement (disrupting habitats at a large scale). If this three points can be solved, that would be the future. But an overall impact study on local habitats and species that ONLY live in sahara must be made. Also the impact on local people (remember that morocco invaded Occidental Sahara and still is at war).

      I don't think you understand the landscape, and as always just like everyone else on the internet you're boinking your mouth around topics you do not know anything about but I'll break it down for you.
      The shifting sands of the Sahara can get up to and around about 1200 meters. Now, the thing is with these mobile tall bastards is they are every bit as wide as they are tall. The weight of the sand will absolutely crush anything unfortunate enough to be under that literal mountain of sand. 1200M is two Shanghai Tower's stacked on top of each other.
      The most irritating part is that there just isn't ONE mountain of sand blowing around being a nuisance, the entire desert is like this... just building random mountains of sand overnight without warning.

  • PhantomSavage

    Though it probably will happen at some point in our future, the very act of constructing infrastructure into the heart of the hottest zone in the Sahara would require the road and construction crews to be equipped with what would probably have to be formerly used NASA space suits and massive water trucks. The heat and direct sunlight in the Sahara is almost otherworldly, especially as temperatures and UV rays only get more and more intense with each passing year. Working in the hot zone of the Saraha will eventually feel more like the surface of mercury than it does the surface of earth, the workers will need thermal and UV shielding and continuous hydration to work under sustained conditions.
    Once the infrastructure is in place and the solar plant is operational, this would no longer be necessary, as workers could be flown in via helicopter or plane in regulated shifts like an oil rig (or you could construct a bullet train with all the power the plant produces), but the building of the infrastructure alone would be an incredible feat of human engineering, innovation, and endurance that would last many years and billions of dollars to accomplish.
    That being said... if we ever hope to one day build something like a Dyson Sphere or a massive Solar Sail.. the Sahara's hot zone would be an excellent place to test and innovate the technology.

      every 20 years they have to be replaced. The material is not biodegradable and is toxic not to mention in 60 years the material needed to make these panels will no longer exist however the more we explained the use that time period could be only 40 years. Oh, and when you add electric Jets, cars, machines, trucks, ships, everything that currently runs on oil it will take more than 7 times the current use of electricity we currently use. Adding that to the equation oil the battery the supply for the material will deplete in 20 to 30 years. You people are ass clowns.

      Hey I just happen to see your comment and thought it would be good to reply, i respect the fact that you tried to englobe the topic from all the angles but i think the numbers that you've mentionned can be a little bit misleading especially the fact that just because Uruguay has +98% of renewable energy that doesn't make it a leading country in solar power because its energy mostly come from the wind. Secondly I think the statement : "Morocco can be a leading state of solar power" concerns in the first place both the size of the country and the rate of its developpement in solar power since it started to invest heavily in the subject and is already getting good results and maybe if you want that can also be due to its strategic location as a part of sahara desert. So maybe in few years we can still see it as a leading solar power if it continues to develop at this rate ^^.

    Considering the amazon predates the sahara by about 200 million years, I don't think it's lack of "fertile dust" is going to faze it much. Though, if the panels did manage to produce clouds and rain you would literally bankrupt the world for a self defeating project. Overcast skies over your solar farm, beautiful.

    I come up with a city concept and power core building design. Unfortunately I'm not that good at science and engineering so it's likely just an idea.
    It would be more than big enough to store large quantities of electricity and should be able to generate a large amount and it is scalable by design.

    One of the most challenging disadvantages is that the panels could be covered with sand easily and then they wouldn't work properly, so they need a big amount of workers to clean them regularly, and not to forget that a sandstorm can uproot them so they should be really well fixed, but at least I think we all agree that Morocco is handling all those challenges in a good way so far.

      That's probably even worse though. The cost of the elevator would just make the already expensive solar panel project even more ridiculously priced. There's also the issue of transporting the energy from the top of this elevator thing (so much transmission loss) the fact that the place underneath the thing would be completely shaded by a tower of solar panels the size of New Mexico during the day which would most likely change the locations weather, or the fact that regardless of where you place those panels, since you still need the same amount anyway you'll still be dealing with that much solar panel waste since pretty good solar panels only have a lifespan of 25 years, and most of the items solar panels are made of cannot be recycled.

      @XxKagarwaxX I am aware of tax heavens, I think we need to combat them though. I assume you mean that countries don't have infrastructure and I think that is just wrong. Countries own most means of transportation (roads, rails, harbors, airports) which are used/rented by companies. Innovation is driven by state funded projects and not by companies (e.g. vaccine development). Companies just take stuff over afterwards because they have the means of production which lets them get a good deal for the patent. So a project funded by the country is then milked for profit by companies which don't even pay taxes.
      I don't think there is even a chance that companies will take the initiative on building large solar panel arrays without heavy state support at which point I would just say "pay them to build it, but it needs to be owned by countries or we will have a crisis soon after."

      @Alex North Alex, you're panicking. A solar farm releases very small amounts of heat. Particularly as compared to the traditional energy sources it replaces. Regional heat levels would drop as less efficient fossil fuels and wood, would plummet in use.
      These border communities are already in the process of being rendered uninhabitable by desertification and temperatures are already rising due to inefficient human harvesting of wood and other unsustainable resources. Replacing this pattern with a solar farm would stop the temperature rise and save these communities.
      And yes, the layout of the farm has a significant effect on the environmental impact. A thin strip of solar panels running the circumference of the Sahara desert placed 30 - 50 miles inland from the nearest communities would dissipate heat without ever being concentrated enough to impact the larger environment as severely as a solid block of panels might. The heat would simply be added to the global heat index, which itself would be going down due to the reduction of fossil fuel usage.
      This scheme balances the need for a nearby workforce with the preference of locating the panels in vacant areas.
