@Dennis Doherty What of it? There's no continental government - nor is there a continental electric grid. Power only goes to where it can be delivered. Egypt might be able to tap in, but if, say, Nigeria or Kenya want some of the energy, they'll have to invest in a grid to deliver it. (Half of the electricity in Nigeria is generated onsite by users, because the national grid is that crappy.)

They could reserve these plants solely for the purpose of energy storage. Plenty of salts could be melted and stored by day to deliver power during at night when the output of normal solar pv panels falls away. I wonder about that storage of molten salt. It's easy to say "like a thermos bottle" but this is a whole different scale and temperature.

REAL ENGINEERING ????? Numbers matter 1 square meter of a panel is approximately 150 watts so as sunlight is strongest when 90 degrees to the panel ,thats the maximum power 150 watts . Maximum power is in the middle of the day so say you get an average 7 hours of total power ( 7 x 150 = 1,050 Kw ) . So please explain mathematically how you get 5 to 7 Kwh ????? thats 5 - 7 times BULL SH.T . Excess heat actually reduces panel ability to generate power and drastically shortens its life span . Then you have dust or should I say, fine sand particles which will cover the panel and reduce capacity unless removed constantly . Of coarse you have considered that in a high wind the sand acts as a sandblaster on both the top and underside of the panel also reducing effective life a panel can be destroyed in one sand storm .

Batteries ? You still have to store the energy so it can be used at night and When there is no sun , Your video doesn't go into any deeps of that . What would the cost be ? Were would you need storage? Each Nation? These battery's are no simple car battery's or phone battery's? There are Huge and require certain elements like Li-on and Cobalt , How much other land usage would be required for the Battery's ?
FDS 4 giorni fa
storage on the required level is simply impossible. The best lithium - ion batteries store 0.2 kWh per kilogram. However, a country like Germany uses about 2 billion kWh every day. If you want to buffer the solar generation you would need at the very least 2 billion kWh of storage (2 TWh) which means 10 MILLION TONS of lithium ion batteries!! Other batteries have significantly less energy density. Thus, the whole concept of powering us with the sun is not going to happen, you cannot buffer the energy.

Molten salt (thorium) nuclear is the real global solution, solar makes some sense in ~30° latitude and lower. But not those huge industrial plants (sand storms) but in city - either roofs or windows - easy to clean or repair Solar is nice extra but not the cornerstone and wind is total BS. Water is def the best renewable

You know, giant copper rods right through the core of the planet would give a good source of heat for spinning turbines. Not quite sure how you'd install them though. but still, would be a good energy source.

Thank you for this! I am Moroccan and these things are NEVER discussed here, so these vids make me love my country and the big guy ruling! And obviously it educates a lot of people as well, solar energy is so fascinating, and it has that utopian connotation, the next big thing in human history... But it needs a LOT of maintainance and a LOT of valuable resources -water being the most important one-. So we still need lots of time to make it manageable and serviceable to the majority of countries!

John Doh
John Doh 5 giorni fa
Just curious. Instead of this big megastructure that spans N. Africa, and I know you alluded to this, why not just get rid of the complexity of these Moroccan installations and just go straight solar panel? As was mentioned, the cost of solar panels is very cheap now. On top of that you get a bit better power output than even 6 years ago. A 400W panel is typical. Panels with 500W during peak hours are already produced. So, if you toss out most of this and just stick with Morocco and sending power to Spain, where if power isn't consumed or transmitted to say France, then it could be stored in grid storage such as ESS redux flow storage which is environmentally friendly, then even though you only get power coming into Spain, since it could be transmitted out of Spain it would still be beneficial. And now, security is much easier. Partners can ensure this benefits Morocco too so there's local buy in for all this. This sounds much easier and simpler than these systems in use right now in Morocco. Simple and easy typically wins if the cost is low. If panels didn't have a long life I could see this being an issue, but today's panels are so good you can expect them generating for a good 3 - 4 decades and EASILY give ROI. Yes, cabling is an issue, but isn't there some newer cabling technology that boosts efficiency or allows transmission of more power? But since it's only making that short run, relative, seems like it wouldn't be hard to do. Maybe EU companies could move some of their manufacturing out of China and into Spain with power coming out of Morocco, OR manufacture in Morocco. I mean talk about a change in economics. Now goods don't have to make that long journey and it benefits the economies you hope it would, your own.

A better idea or suggestion, instead: the Sahara desert should become the world plant, and a green one, which will give way to building world major industrial cities (green ones) and universities on the spot. Europe might stop or reduce its industrial capacity and transfer it to the Sahara and Mediterranean region. So Africa has got a competitive advantage for next or future industrialization processes. Can it be built not at the level of the ground, but very high,1 or 2 kilometers higher? To capture more heat and create shade under the facilities where you can grow little forests in the desert?

Not a physicist or engineer, but I find it hard to imagine that 500-degree Celsius heat can be efficiently turned into harnessable steam. Steam is very powerful at temperatures barely exceeding the boiling point, as in old time locomotives. The turbines must be massive or else turn at super high speeds to use 500-degree Celsius steam, either way requiring highly specialized alloy bearings and intense lubrication. If the electric output is also massive, the receiving conductors carrying the current must be super-hot and prone to breakdown. It seems to me the whole concentrator concept would work better at lower temperatures, requiring fewer controlling algorithms, and requiring less maintenance. Why not build smaller fields with more focal points? Also surprised that there is no mention of sand storms. Surely there must be occasional high winds in the desert, which would pulverize and pit the surfaces of the glass mirrors, destroying their reflectivity, and requiring replacement vs simple "cleaning." Bulldozers would be routinely required to move the drifts of sand before the whole installation were to get buried.

Three things: Imagine how the Russians and China would want to be able to destroy such pipelines as a strategic capability. The region’s religious maniacs would likely not be able to ruin enough to cause a real problem for Europe. There is zero need to draw cables to countries on the Arabian peninsula which has the same capabilities and wouldn’t want to depend on others to supply what they can already produce. Problem solved - you’re welcome. Israel wouldn’t want to depend on energy delivery from the Muslim countries and they wouldn’t want to deliver it to their arch enemy. That region would definitely not be a good route for anything that can be broken, anyway.

The Reality In the name of Allah, the Beneficent, the Merciful.[69:1] The Reality! [69:2] What is the Reality ? [69:3] Ah, what will convey unto thee what the reality is! [69:4] (The tribes of) Thamud and A’ad disbelieved in the judgment to come. [69:5] As for Thamud, they were destroyed by the lightning. [69:6] And as for A’ad, they were destroyed by a fierce roaring wind, [69:7] Which He imposed on them for seven long nights and eight long days so that thou mightest have seen men lying overthrown, as they were hollow trunks of palm-trees. [69:8] Canst thou (O Muhammad) see any remnant of them ? [69:9] And Pharaoh and those before him, and the communities that were destroyed, brought error, [69:10] And they disobeyed the messenger of their Lord, therefor did He grip them with a tightening grip. [69:11] Lo! when the waters rose, We carried you upon the ship [69:12] That We might make it a memorial for you, and that remembering ears (that heard the story) might remember. [69:13] And when the trumpet shall sound one blast [69:14] And the earth with the mountains shall be lifted up and crushed with one crash, [69:15] Then, on that day will the Event befall. [69:16] And the heaven will split asunder, for that day it will be frail. [69:17] And the angels will be on the sides thereof, and eight will uphold the Throne of thy Lord that day, above them. [69:18] On that day ye will be exposed; not a secret of you will be hidden. [69:19] Then, as for him who is given his record in his right hand, he will say: Take, read my book! [69:20] Surely I knew that I should have to meet my reckoning. [69:21] Then he will be in blissful state [69:22] In a high garden [69:23] Whereof the clusters are in easy reach. [69:24] (And it will be said unto those therein): Eat and drink at ease for that which ye sent on before you in past days. [69:25] But as for him who is given his record in his left hand, he will say: Oh, would that I had not been given my book [69:26] And knew not what my reckoning! [69:27] Oh, would that it had been death! [69:28] My wealth hath not availed me, [69:29] My power hath gone from me. [69:30] (It will be said): Take him and fetter him [69:31] And then expose him to hell-fire [69:32] And then insert him in a chain whereof the length is seventy cubits. [69:33] Lo! He used not to believe in Allah the Tremendous, [69:34] And urged not on the feeding of the wretched. [69:35] Therefor hath he no lover here this day, [69:36] Nor any food save filth [69:37] Which none but sinners eat. [69:38] But nay! I swear by all that ye see [69:39] And all that ye see not [69:40] That it is indeed the speech of an illustrious messenger. [69:41] It is not poet’s speech - little is it that ye believe! [69:42] Nor diviner’s speech - little is it that ye remember! [69:43] It is a revelation from the Lord of the Worlds. [69:44] And if he had invented false sayings concerning Us, [69:45] We assuredly had taken him by the right hand [69:46] And then severed his life-artery, [69:47] And not one of you could have held Us off from him. [69:48] And lo! it is a warrant unto those who ward off (evil). [69:49] And lo! We know that some among you will deny (it). [69:50] And lo! it is indeed an anguish for the disbelievers. [69:51] And lo! it is absolute truth. [69:52] So glorify the name of thy Tremendous Lord.

The problem I have with this kind of thing and solar power is that the sun is supposed to strike the surface of the earth to warm our environment if you are going to put solar panels where the sun should strike on the planets surface you are surely going to cool the planet down the same principle as more ice on the North and South pole reflects the sunlight a solar panel will absorb heat and solar radiation and so on it is going to be an accident waiting to happen

A thinker, you're rare. Hello there traveler. How do you think we made it this far? We played our role as another form of energy and tried our luck and evolved with it. The lesson being taught is that things change and must adapt to that change because that is the rules set on us from tiniest things to the enormous things. Don't let go of that curiosity, creativity is a beautiful thing. Sometimes I wonder what is the universe running away from that it must expand continously, what error is it trying to hide from us?

The batteries needed to store used for energy, raw materials to create new photovoltaic cells, and what to do with the waste product after the solar panels life expectancy has passed are all great environmental concerns that I guess we're just going to pass on to the next Generation? It seems like the progress that we're making today is falling into the same pitfalls that the wonderful brand-spanking-new energy source of oil did a century ago. I'm not in any way advocating against solar, what I am saying accept the reality is the answer. There must be more than just wind and solar. Thorium and liquid sodium reactors, Hydro where appropriate, geothermal where appropriate, carbon capture advancements and tax incentives to install in every current plant. Pluralism, not monocultures. Diversity is our strength.

The easiest way to increase viability of large, renewable energy infrastructure projects is to reduce energy consumption. If less energy is needed, less needs to be generated, as any five-year-old could tell us. I can barely suspend my disbelief as to why this is never, EVER, mentioned. Perhaps because reduction has been framed in terms of austerity for the sake of energy giants' profitability, rather than an absurdly simple endeavor that combines low social impact with high rate of success. That wouldn't do to say, I suppose.

The blue curve is the flux without GHGs in the atmosphere. The black curve represents the flow at 400 ppm CO2, current concentration. Green has no CO2 at all and red has doubled CO2 (800 ppm). The x-axis is the frequency in wavenumber units and the flux is in (mW cm) / m2. The additional forcing caused by the doubling of CO2 is the integrated area of ​​the distance between the black line and the red line, major differences are highlighted in yellow. The rest of the figure is explained in the text. The data used is from HITRAN and the figure is very similar to Figure 4 of (Wijngaarden & Happer, 2020). clintel.org/the-greenhouse-effect-summary-of-the-happer-and-van-wijngaarden-paper/

But solar plants generate DC current. If DC is the preferable way to transmit power over long distances, why convert it to AC in the first place?

How much energy is required to manufacture a solar panel? I keep seeing conflicting information, some stating that the energy required to buy a solar panel is more than the energy created over its lifetime. The end result is consumers purchase clean energy created by dirty energy - still the same amount of dirty energy being used, no improvement to CO2 & climate change.

More pie in the sky. The panels have a very short life and have to be replaced constantly. There will still be the need for large amounts of fossil fuel. The amount of pollution and heat generated by the industrial manufacturing of all the components needed will be disastrous, not to mention the FACT that we are running out of many of the resources needed to simply produce all these components.

Rolls royce are developing a 470MW small nuclear reactor. A smallish building producing more power than the four Noor plants combined.

I do not think the criticism of "exploiting" north africa with such projects is a fair claim. This could have been a win-win project (and maybe it will, in the future). But of course, similar projects funded by local countries themselves will get better acceptance.
