Saudi Arabia and the United Arab Emirates import millions of tons of sand every year despite living on immense deserts

The story is striking in itself: Saudi Arabia and the United Arab Emirates, two countries closely associated with the desert, import tons and tons of sand every year. So striking, in fact, that the first intuition is that it is false. But, as soon as you get closer to it, you discover that not only is it true, but it is more interesting than it seems. Because yes, these countries import a lot of sand. In 2023, only the United Arab Emirates bought more than six million tons. And it is surprising, of course, because these are two countries located on enormous deserts. The explanation, however, is simple: the sand they have is not suitable for certain things. At a technical level, what is known as “eolian sand” (that which the wind accumulates in dunes) is very fine, very uniform and very rounded. That makes it a poor sand for making glass, concrete or other industrial products. It is not that it cannot be used, but it requires adjusting the mixtures, controlling the granulometry and impurities (fines), and carefully balancing the manufacturing processes. That is to say, the process ends up becoming so expensive that it is cheaper to import sand that is more suitable for standardized processes. And this, ultimately, should not surprise us. Sand is, today, the second most exploited resource in the world (only after water). The United Nations Environment Program estimates that every year 50,000 million tons of sand and gravel are used. What’s more, the lack of sand is so obvious that there are criminal networks that traffic with her internationally. However, we are not talking about just any sand. There are, as is evident, many types of sand. For what is not interesting today we can distinguish natural sand (HS 250590) and siliceous/quartz sand (HS 250510). The Gulf countries import, above all, the second. Emirates, to give an example, is spent half a million a year in the first and 87 million in the second. That is to say, although they are countries ‘rich’ in sand, they do not have the sand they need. A sand, moreover, with very specific specifications (granulometry, purity, humidity, fines, contaminants, consistency of supply) and that are basic for glass, foundry, filtration or the chemical industry. However, they also import natural sand. And this is interesting because, as they point out in the UNthis only makes clear the significance of the problem of governance and externalities. Despite having usable sand, in many cases it is preferred to buy from other countries (such as Oman) to avoid the negative externalities of draining sand from their coasts and deserts. Something that can alter livelihoods (fishing, agriculture due to salinization, coastal tourism) and increase vulnerability to storms. In the summer of 2019, the couple who became famous was arrested in Sardinia for hiding 40 kilos of sand in his trunk. That was the anecdote, the problem was another: that beyond mass tourism, the tensions on the sand are increasingly greater. It is something that has only grown and is normal. The world is not here to do without one of its most valuable resources. Image | Lars Portjanow In Xataka | We are running out of sand. And there are already traffickers who negotiate with it in India or Morocco

import “capsule houses” from China

Spain needs affordable housing. A lot. Hundreds of thousands, according the estimates of the experts who have calculated the hole that the country would need to cover to get out of the housing crisis in which it has been immersed. That is why it is not surprising that solutions like the one that has just been launched a company of Pontevedra generate expectation inside and outside the sector. Their bet consists of neither more nor less than importing small “capsule houses” Chinese that can be installed in just a few months and are available for a few tens of thousands of euros. The question is… Will they help solve the problem? What has happened? That the Spanish real estate market adds a new residential solution. That is news in itself in a context marked by pronounced imbalance between supply and demand and escalation of prices. However, in this case there is another reason why the advertisement has aroused interest: what it offers Caslua Importa company located in O Grove (Galicia), is a solution that stands out for its costs and times. In fact they use a quite descriptive term. What they sell is neither more nor less than “capsule houses”. Capsule houses? Exact. To be more precise, “modular capsule houses”a term that gives a fairly precise idea of ​​what this Galician company offers. His online catalog It is divided into two categories: houses and modules. All prefabricated and with a range of sizes ranging from 5.8 meters long by 2.2 wide and 2.4 high (it even has smaller modules for offices) to structures of more than 11 meters and almost 40 m2 with a living room, bathroom, bedroom and terrace. Shapes, sizes and features change between some models and others, but philosophy is always the same: “Compact, efficient housing solutions ready to respond to the needs of housing, work or entrepreneurship.” In fact, those in charge usually emphasize two ideas: costs and times. The price range moves between 25,000 and 80,000 euros and the house would be ready in a few months. “In less than three you can have a fully assembled house to live in,” assures one of the founders of the firm, Antonio Luaña. “Manufacturing periods are around 30 days and then 60 days of transportation.” What are they like? It depends a lot on the model, but the company insist in that the capsules are modular, sustainable and can be adapted to be “self-sufficient”. After presenting its offer in media such as The Sixth, Antenna 3 either The Voice of Galiciathis week the signing showed to a hundred businessmen, politicians and neighbors a 38 m2 capsule home installed in O Grove and that includes a bathroom with a jacuzzi, a small kitchen with an oven and hob, a living room and a double bed. “It is around 85,000 euros. If you take away things from what it has, it can be around 73,000. Prices vary, but the structure is the same,” Luaña points out. Who makes capsule houses? The news shared by Caslúa assure that these are homes manufactured in China and that the Galician firm is dedicated to marketing them in Spain and Portugal. “When I went to China and saw them, I thought: How is this not in Spain? We have to take it,” Antonio tells. A quick search shows that in the Asian giant they work this type of small format residential solutions. Glamini includes different modelsalthough it is also dedicated to the manufacture of floating houses or cabins. Is it something new? Yes. And no. To start the concept of “capsule house” can be traced in foreign markets and in recent months there has been talk about them in other regions of Spain, such as Navarre. In China it is also possible to find several manufacturers. Even AliExpress they have launched its marketing. The undeniable thing is that the concept has aroused interest and joins a wave that goes beyond the “livable capsule” concept: that of the search for new forms of construction that make it possible to meet the high demand for housing. In recent years it has been gaining strength, for example prefabricated housingindustrialized and modular, which speeds up construction times without the owner having to give up configuring his residence. It is no longer just a matter of individuals betting on that formula. In recent months in Spain we have also seen businessmen resorting to that same solution to raise a multi-story hotel (it happened in Zaragoza) or even to institutions getting interested for her. Are they all advantages? The important thing is to know the characteristics of each option. And assess issues such as costs. For example, if we talk about a 38 m2 capsule that costs 73,000 euros, the square meter costs 1,900 euros, which (even assuming that this price includes the equipment) is noticeably above of the prices that are handled in some markets in Spain. Not to mention that to install a capsule it is necessary to have land that meets all urban planning requirements. The TVG network remember For example, even though they are modular houses, they cannot be installed on rustic land, unless they are linked to an agricultural operation.

Europa presumes to be a renewable power, but it turns out that it wants to import energy directly from Africa

The desert sun hits strongly the dusty plains of Tunisia and Algeria. At first glance, they look like empty lands, but they could soon become a mosaic of wind towers, solar fields and batteries capable of storing as much electricity as to feed millions of European homes. It will not be energy for nearby cities: the Mediterranean will cross through submarine cables to light homes, factories and trains on the other side. The European Union has decided that its energy transition will not be built only at home: a good part of its green future will travel from North Africa. A priority list. The European Commission He has just updated Its list of cross -border projects of renewable energy, incorporating five new plans that will have preferential access to the financing of the mechanism connect Europe (CEF) and greater international visibility. Among them, one stands out that symbolizes the new energy strategy of the block: Medlink. According to documents cited by BloombergMedlink plans to install 10 GW of wind energy, solar and storage systems in Tunisia and Algeria. Electricity will travel through two high -voltage marine cables to Italy, with an annual capacity of 28 SWH, enough to cover about 8 % of the Italian electrical demand. The project, promoted by the Italian company ZHEROcould be extended to supply energy to Austria, Germany and Switzerland from 2030. The European Commission establishes that, to enter its list, a project must involve at least two Member States or a Member State and a third country. With this update, thirteen initiatives are part of this special category. Other in motion actors. The impulse is not limited to Tunisia and Algeria. Starting with Morocco that aspires that renewable energies represent 52 % of its installed capacity in 2030 and has launched six green hydrogen megaprojects. Among the companies involved are the Spanish Action and Cepsa, together with European, Arab, Chinese and American giants. These projects will not only produce hydrogen, but also ammonia, steel and green industrial fuels, bound for both international markets and the supply of Europe, According to data collected in Xataka. For its part, Egypt has attracted billions in European investments for solar, wind and green hydrogen plants, much of whose production is destined for export. However, A report reported by The Guardian de Greenpeace He warns that this strategy could limit local decarbonization, keeping the country dependent on imported fossil fuels such as mazut, a oil derivative with high contaminating content. In parallel, Themed also advancesan underwater interconnection project of 600 MW between Tunisia and Italy, independent of Medlink and centered on hydroelectric energy. With its scheduled implementation for 2028, it has financing from the European Reconstruction and Development Bank, the Green Climate Fund and the German Development Bank, As reported Enterprise. The implication of this bet. In Brussels they see it as a double play: accelerate the green transition and reduce the dependence of Russian gas, which collapsed after the invasion of Ukraine. Italy gains weight as a renewable entrance door to the north, and countries like Spain They restore key energy relationships, as the agreement between Naturgy and the Algerian Sonatrach to set gas prices until 2027. The European Commission defends that these interconnections and megaprojects are “essential to meet the objectives of the European Green Pact and reinforce energy security” at a time of global uncertainty. Critical voices have not been long in coming. As they have detailed in a reponnet for The GuardianGreenpeace denounces that Europe runs the risk of “outsourcing” socio -environmental costs to the global south: intensive use of water in arid areas, displacement of communities and prioritization of the European supply on local development. Hanen Keskes, responsible for campaigns of the organization in the Middle East and North Africa has sentenced: “The global north must assume its responsibility and build domestic renewable capacity, instead of outsourcing costs to the global south.” Looking to the future (almost) immediate. The EU has set the objective of importing 10 million tons of renewable hydrogen in 2030. Morocco wants to be one of the main exporters together with Algeria and Egypt, a trend that extends throughout North Africa. In the European energy map, the south of the Mediterranean is ceasing to be a border. Under the sea, high voltage cables will join sunny deserts with industrial cities. It is a historical opportunity to accelerate the decarbonization of the continent provided that, as critics warn, the light that comes to Europe does not leave those who live under the sun that generate it in shade.

Nvidia has beat its income record again. Paradoxically, Wall Street does not seem to import much

The Fever continues to spur Nvidia in the stock market. The company led by Huang has presented again record results for your fourth fiscal quarter. And it has been making the rupture of records into a while. Why is it important. This comes shortly after concerns about Deepseek’s impact and its efficiency in the market that dominates Nvidia. About the idea that less hardware and less power was necessary to continue advancing in AI. Which caused the huge hole in Nvidia bag. The most prominent point of the results was the Awesome Blackwell startthe new chips architecture for Nvidia. Colette Kress, financial director of the company, explained that Blackwell generated 11,000 million dollars in income, exceeding all expectations and becoming “the fastest product launch in the history of our company.” In figures. The data centers business, where technology is concentrated for AI, remains the main growth engine with 35.6 billion revenue in the quarter, 16% more than in the previous quarter and 93% more than in the same period of the previous year For the full fiscal year, this segment reached 115.2 billion, more than double the previous year. The total revenue of the quarter reached 39.3 billion, 12% more than in the previous quarter and 78% higher intelligible. Between the lines. Nvidia is changing her strategy to deal with competition. Jensen Huang emphasized The call with investors that are designing specific platforms for “reasoning AI”, a type of AI that requires up to 100 times more computing capacity than the “traditional” generative AI, which reinforces their most powerful need for hardware even against more efficient models. Reasoning models such as O3 of OpenAi, Deepseek R1 and Grok 3 They require much more intensive processing. Blackwell offers 25 times more yield for these models compared to the previous generation. Infrastructure demand for AI is promoting initial orders of Clusters of 100,000 Gpus or more. And now what? Nvidia has already announced that he will present Blackwell’s successor, called Blackwell Ultra, in the second half of this year, maintaining his annual rhythm. Jensen Huang has confirmed that this transition will be simpler than Hopper’s Blackwellsince it will use the same system architecture. The contrast. Despite the impressive results, Nvidia’s shares barely reacted in the market after the presentationa behavior very different from that seen in previous quarters. The reason: investors perhaps see with caution the reduction in gross margins (from 75% to 73%) and the lowest percentage growth compared to previous quarters, although it remains extraordinary for a company that has established itself as the second most valuable in the world. The big question. Will Nvidia be able to maintain your technological and financial domain against increasingly intense competition and that also threat from China? It seems inevitable that, although Nvidia’s position will remain strong, a certain decrease in demand in favor of new competitors comes. And above all, as the huge investments made by companies in AI do not have a clear and lucrative return, something that seems quite feasible. Maybe it is time to readjust expectations.
