We’ve found the secret ingredient for using desert sand in construction: sawdust and a giant sandwich maker

by

At a time when humans do not stop building and erecting large buildings, there is a problem that should concern us more and more: there is a lack of sand to make concrete. But here anyone can laugh, since we have great deserts on the planet where there is a huge amount of sand that we could use without any problem. But it’s not that easy. The problem. Today, traditional concrete is quite exquisite, since river sand is necessary to achieve a good result. And it has to be that way, because the desert sand is too round and fine to be able to “stick” well. But the truth is that we were running out of this sand so necessary to continue building. In Xataka The rain has transformed the driest desert on the planet into a sea of ​​flowers. It’s a sight to behold and a problem for experts We have a solution. The University of Tokyo and the University of Norway they have hit the key to turn the tables, and the solution is not only to use the desert sand that a priori we have left over, but rather it is to mix it with plant waste to create a material that has received the name Botanical Sandcrete. The recipe. The recently published study details a process that deviates from traditional cement setting, using a hot-pressing technique instead. And for this you only need two ingredients: Fine desert sand which, as we have said before, is useless for conventional concrete due to its morphology. Wood particles and plant additives that act as organic “glue.” All this, together with a temperature of 180 ºC and high pressure, means that the wood components help create a solid matrix that traps the grains of sand and transforms them into a handful of powder in a block that has great mechanical properties. {“videoId”:”x7znesx”,”autoplay”:false,”title”:”Self-consumption building THIS IS HOW THEY WORK – Solar panels in apartment blocks”, “tag”:”solar”, “duration”:”564″} What is it for? Here we should not be happy to find an alternative to a problem that we already had on our heads, since we are not going to be able to build skyscrapers with these tomorrow. Here the researchers point out that the material, as it is right now, is a non-structural alternative.  In this way, its use is mainly focused on pavements, urban tiles and enclosure blocks or outdoor furniture. Things that are ultimately not pillars for large buildings, but do allow us to save river sand. Your advantage. Having an alternative, although it cannot be used in everything, allows us to drastically reduce dependence on quarries and the transportation of river sand. An action that results in the destruction of river ecosystems around the world by removing a fundamental element. In addition to all this, using wood waste and plant additives means that it has a much smaller potential carbon footprint than concrete based on classic cement. In Xataka 30 years ago the US was the country that dominated rare earths. This graph shows how China devastated at dizzying speed Its importance. To date, most attempts to use desert sand involved expensive chemical treatments or mixing them in very low percentages with conventional sand. But the focus of these researchers involves the use of biomass, making us a perfect example of a circular economy. And if we see the full context of the situation, we are taking advantage of a resource that is very abundant but a priori useless like desert sand, along with a byproduct of the logging industry. But logically it still remains to be seen how it behaves over time and how well it endures adverse conditions. Although a priori we are facing great news.

transforming desert sand into the cheapest and most durable road material in Africa

by

Honda is experiencing one of its most complicated moments. On the one hand, it has canceled several launches of its electric cars in North America, has paralyzed the development of Afeela which it developed in collaboration with Sony and has announced losses of around $15.7 billion. Now they are in a moment of restructuring to get out of the slump, but they have not left aside some of their most experimental projects. One of them is PathAhead, a startup that emerged from its internal incubator that has presented a construction material made of desert sand with which it intends to pave roads in Africa. The problem they want to solve. Only about 20% of African roads are paved, according to data from Honda itself. This figure has a direct impact on the region’s economy, since in the end a place where transportation access is difficult makes logistics more expensive, limits access to markets and slows down development. Furthermore, according to the firm, conventional materials for road construction (natural sand and crushed stone) present variations in resistance depending on their geological origin, which makes it difficult to guarantee uniform quality. The solution: desert sand turned into arid. As we have mentioned before, the company behind this project is called PathAhead, and it has developed a material that it calls Rising Sand. The company describes it as the world’s first artificial aggregate made from desert sand. The process consists of agglomerating fine grains of sand (about 100 micrometers in diameter) into larger, more uniform particles using heat and pressure, increasing their resistance. Image: Nikkei Asia The result, according to the company, is roads with a useful life of more than 20 years, double that of those built with conventional materials, and a life cycle cost that is 60% lower, according to its estimates. The deployment plan. PathAhead plans to begin demonstration trials in Kenya in 2027, followed by Tanzania and South Africa. If the results are positive, mass production will begin in 2028 in its own factory in that country. The startup’s financial goal is to reach revenue of $270 million by 2034. The company has so far raised about 136 million yen (approximately $850,000), with Honda as one of its investors. Where PathAhead comes from. The startup was born within the Ignition program, which Honda launched in 2017 to encourage the creation of new businesses among its employees. Masayuki Iga, its founder and CEO, worked for years at Honda’s research center developing automotive materials. “I created PathAhead with the desire to apply the technologies and knowledge accumulated in that experience to directly address the challenges of our society,” declared Iga during the presentation in Tokyo. Why it draws attention now. Sling has increased its spending on R&D by 55% in the last five years, to exceed one trillion yen in the recently closed fiscal year. That the company maintains and even expands its commitment to internal innovation while undergoing a profound restructuring of its core business is, at the very least, a sign that it does not want to reduce its long-term bets. If PathAhead can prove that its material works on an industrial scale, it could become more than just an experimental project. We’ll see if it ends up having a place in the industry.

Iceland has solved it in the middle of the desert

by

Trapping carbon dioxide emissions and literally turning them into stone seems like an invention straight out of the blue. Futuramawhere in the future everything is recycled. The problem is that this trick of underground alchemy hid a terrifying small print: his exorbitant thirst. To get carbon to mineralize underground, the system needs to swallow absurd amounts of liquid, specifically between 20 and 50 times more water than the mass of CO₂ we are trying to store. However, a new industrial-scale study published in the magazine Nature just rewritten the rules of the game. An international team, with researchers from Iceland, Saudi Arabia and Italy, has shown in the western Saudi desert that it is possible to petrify CO₂ without wasting a single drop of external fresh water. Salvation under the sands of Saudi Arabia. As the authors of the research detail, this area is a real challenge: it is full of large facilities that emit a lot of CO₂, such as refineries and desalination plants, but it lacks the underground saline aquifers or sedimentary traps that are traditionally used to inject carbon. Salvation was under his feet. About 24 kilometers from the Jizan Economic Complex and Refinery, geologists took advantage of an immense bed of highly fractured volcanic rocks (basalts) that have been there for between 21 and 30 million years. There they tested an ingenious system for recirculating subsoil fluids. The gigantic “soda” trick. To carry out the experiment, the engineers used two main wells, separated by just 130 meters: one functions as a “production” well (extracts water) and the other as an “injection” well. The process is a closed circuit and isolated from the atmosphere so that oxygen does not enter or gas escape. They extract the water that already lives in the depths, circulate it through pipes and, 150 meters underground, inject pure CO₂ into it in the form of bubbles until it completely dissolves. According to the project scientists, dissolving the gas in water has two brutal chemical and mechanical advantages: It gets heavy: CO₂-laden water is denser than regular still water, so it creates a non-buoyant fluid, greatly limiting the risk of the gas migrating to the surface and back into the atmosphere. It becomes acidic: This liquid is acidic and greatly accelerates the dissolution of the silicate minerals present in the basaltic rock. As the rock dissolves, it releases metals that provide the cations needed to form stable minerals, such as calcite. A question of geopolitical survival. The data from this pilot is a resounding success. The team injected 131 tons of CO₂ into the subsoil. After monitoring the area with trackers, they discovered that approximately 70% of all that injected carbon had been mineralized within ten months. Measurements showed that the concentration of dissolved inorganic carbon in the returning water had been reduced by 90% compared to what was initially injected. Reusing water from the reservoir itself offers substantial advantages. Not only do you forget about bringing external water, but you also reduce the risk of the pressure of fluids underground increasing dangerously. Furthermore, by injecting water that has the same composition as the original underground reserve, the risk of compatibility problems, such as losses of permeability in the reservoir, is reduced. The current dimension. As we recently analyzed in Xataka In the wake of military escalation in the region, the real Achilles heel of the Arabian Peninsula is not oil, but thirst. Countries like Saudi Arabia depend 70% on their desalination plants to survive. In a scenario where the supply of fresh water is a strategic vulnerability and a matter of biological survival, allocating massive volumes of water to bury emissions was simply unfeasible. Therefore, this advance opens the door for the Middle East – where a large part of global oil production is also concentrated – to be able to use its basalt rocks to store carbon without sacrificing a vital resource. A providential accident. Sometimes setbacks are the best of tests. In September 2023, the submersible pump in the extraction well broke down. When the technicians brought it to the surface, they found its interior full of rock grains cemented by up to 14% calcite, as well as other minerals such as siderite and ankerite. The isotope analyzes made it clear: these solid cements were formed from the CO₂ injected during the pilot project. The gas had literally petrified in the very bowels of the machine. An “energy bargain”. As if that were not enough, we must add energy savings. As the research details, injecting CO₂ with this method requires a surface pressure of only 12 to 14 bars. That’s 8 to 16 times less pressure than conventional carbon capture plants require. Basically, CO₂-laden water is drawn into the system driven by gravity. Regarding its future potential, engineers calculate that the underground pores of this particular area (estimated between 24,000 and 43,000 m³) would have enough space to house between 22,000 and 40,000 tons of mineralized CO₂. Geology dictates: the limit of the stone. Every geological technology has its own physical limits. As experts explain Natureas water, CO₂ and basalt interact, the total volume of solid minerals increases. This means that the pore space is reduced and can end up blocking water flow paths in the long term. To get around this problem, the researchers propose that we may have to resort to fracturing the rock (fracking), an option still little explored in basaltic systems. What is clear is that this technological innovation is proposed as a great complement to conventional capture systems, not as an exclusive alternative, since in the end it is the geological conditions that rule. But thanks to this pioneering experiment, there is something we can take for granted: the lack of rivers or fresh aquifers is no longer an excuse for not returning our emissions to the subsoil and turning them into stone.

Saudi Arabia had billions to build the future in the desert. He has decided to sacrifice them to destroy Iran

by

The cranes have stopped roaring in the Tabuk desert. There where it should rise a colossal artificial lake at 2,600 meters high and a science fiction metropolis valued in billionsToday the priority is to look at the sky looking for the trail of ballistic missiles and kamikaze drones. Crown Prince Mohammed bin Salman (MBS) had promised the world a glass and petrodollar utopia called NEOM, a monument to his own ego designed to whitewash the regime’s image. However, the harsh reality of the Middle East has ended up imposing itself on the renders in 3D. A crossroads in the gulf. We are looking at what is now, for all intents and purposes, a Third Gulf War, and Saudi Arabia has reached a historic crossroads. Caught in the war waged by the United States and Israel against Iran, the Saudi monarchy faces an existential dilemma: save its economy and its megalomaniac pharaonic project, or take advantage of the chaos to dismantle, once and for all, the regime in Tehran. And judging by the shadow movements of its leaders, Riyadh seems willing to let its economic utopia bleed if it means it can win this war. Facing the gallery. Behind closed doors, Saudi Arabia’s message is one of absolute containment. In recent communicationsthe Saudi government has insisted that it has “always supported a peaceful resolution” and that its only priority is defending its population and infrastructure from daily attacks. This is what an analysis by Dr. Turki Faisal Al-Rasheed has defined as “strategic patience”: a tactic in which Riyadh avoids direct confrontation to protect its investments, while subtly encouraging the weakening of its regional rival. The reality is more complex. However, the leaks tell a very different story. As revealed The New York TimesBased on sources informed by US officials, MBS has been privately pressuring US President Donald Trump not to stop the war. The crown prince sees the current US-Israeli military campaign as a “historic opportunity” to destroy Iran’s hardline government. The talks have reached the point where MBS would have advocated for ground operations and even the military takeover of Kharg Island, the Iranian oil heart. The diplomatic board is abuzz. Mohamed bin Salmán’s phone does not stop ringing, as he urgently needs to shield his vital infrastructure from attacks and, to do so, he relies on the Western umbrella. As detailed ReutersBritish Prime Minister Keir Starmer personally telephoned MBS to condemn the Iranian offensive and confirm the deployment of more British defensive military equipment. London’s goal is to protect the kingdom and try to ensure that the sea trade route does not completely collapse. But while MBS is piling up shields and secretly pressuring Trump not to relax the blow against Iran, other regional allies are desperately trying to put out the fire before it devastates the entire Gulf. As revealed by the agency AnadoluPakistan’s Prime Minister Shehbaz Sharif contacted the crown prince to underline the “urgent need” for a de-escalation. Islamabad’s move is not a toast to the sun: Pakistan has emerged as the great shadow mediator, to the point of offering to host direct talks between the United States and Iran based on a 15-point American peace plan. The sacrifice of Vision 2030. “It’s the last thing he wanted. He wants stability and order, he doesn’t want missiles or drones flying.” This is how forceful an expert seemed consulted by him Financial Times. The diplomatic “detente” that Saudi Arabia had signed with Iran in 2023 has been shattered. Iranian retaliatory attacks have hit the giant Ras Tanura refinery, the Shaybah field and the Prince Sultan air base. The cost of this war for MBS’s dreams is already incalculable. Formula 1 had to cancel its April races. In the entertainment sector, the CEO of Savvy Games Group recognized that the war escalation It will “cool the perception” of Saudi Arabia as a safe destination for investment of 38 billion in eSports. The biggest collateral victim: NEOM. The artificial lake project Trojenaawarded for $4.7 billion to an Italian construction company, is already facing leaks about delays of between three and four years. The 2029 Winter Games have been postponed indefinitely and the extra costs suffocate an already deficient budget. The war and instability in the Red Sea discourage foreign investment, vital for these science fiction cities to go from render to reality. The reality of the Saudi coffers is critical. As revealed The New York TimesEven before the conflict broke out, the crown prince was already facing serious financial challenges. The 2030 deadline is approaching and the government assumes budget deficit forecasts for the coming years, suffocated by excessive spending on megaprojects and vast investments in artificial intelligence that are straining the country’s resources to the limit. And a prolonged war threatens to blow everything up, since MBS’s success depends on a single factor that is currently non-existent: a safe environment for investors and tourists. Holding the pulse. To withstand the challenge, Saudi Arabia has had to resort to an engineering work born of fear in the 80s. With the Strait of Hormuz strangled by the Iranian threat, Riyadh has activated its logistical “antidote.” State oil company Aramco is pumping against the clock through the East-West Pipeline, a 1,200 kilometer pipeline that crosses the desert to the Red Sea port of Yanbu. The objective is to move up to 7 million barrels a day by land, avoiding Tehran’s missiles. The landscape in Yanbu is like something out of a movie: an “army” of at least 25 supertankers (VLCC) crowds on the coast to evacuate some 50 million barrels. However, there are no magic solutions. The port has a physical funnel (it can only load between 4 and 4.5 million barrels per day) and, in addition, ships must cross the Bab al-Mandab Strait, exposing themselves to the Houthi rebels. Added to this is that the pipeline only moves crude oil, leaving markets such as Europe without their vital supplies of refined products such as diesel, exacerbating the global energy … Read more

The rain has transformed the driest desert on the planet into a sea of ​​flowers. It’s a sight to behold and a problem for experts

by

The Atacama Desert bloomed again in spring. After the August rains, more than 200 species from the Chilean region were activated and provoked the first major flowering since 2017. The Internet was filled with impressive photos, but (beyond the hype) there is a central problem: increasingly clear signs of a destabilized climate system. What has happened? In August 2025, a storm left accumulated between 40 and 60 mm in the Chilean Atacama Region. Specifically in the south: in Huasco, Freirina, Vallenar and the Llanos de Challe National Park. As a consequence, flowering started in the third week of September and reached its peak between the end of September and mid-October. He show was amazing: a mantle of red and yellow añañucas, of sighs, of huilles, of guanaco legs and lion’s claws. And why are we talking about this now? It’s a good question. Historically desert blooms occurred between 5 and 7 years. Typically linked to El Niño phenomena. In the last 40 years, Chile has recorded about 15 superblooms. The striking thing about this case (as happened in 2022 and 2025) is that it is linked to La Niña conditions. And, indeed, one may be a coincidence, but three so close together mark a trend. And the problem is that more blooms are not always good news. And so? As explained Maria Fernanda Pérezan ecologist at the PUC of Chile, out-of-season blooms generate a gap between flowering and pollinators. What’s the point of having pollen if we don’t have bees to do their job? Indeed: absolutely nothing. What’s more, if climate change causes this type of blooms on a regular basis, this deregulation could cause very serious problems. After all, just think that a guanaco paw seed can spend fifteen years on the desert floor until its time comes; If it germinates and there is no one to pollinate it, there will not be another seed. Climate change is going to cause us more problems than we are able to imagine. Because the serious thing is not the sea level, the melting of the glaciers or the rise in temperatures (that too). The most important thing is these little things that change everything. Things so small that we haven’t thought about them.

A plant was on the verge of extinction in the Mojave Desert. So they built a solar park on top

by

The Mojave Desert is not only a paradise when it comes to filming movies, setting video games and name operating systems: It is also home to thousands of plant species that are accustomed to an extremely hostile climate. It is estimated that there are about 2,000 species and a very specific one is in danger of extinction. Until they decided to build one of the largest photovoltaic plants in the United States on top of it. The Gemini Solar Project. In short. The journal Frontiers in Ecology and Evolution revealed a few weeks ago the results of a curious study. The ‘threecorner milkvetch’ plant (which has a name for everything except a plant) went from 12 specimens in the Mojave Desert to 93. This plant was being evaluated for inclusion in the Endangered Species Act in the United States and not only has its number multiplied: the new plants are larger and produce more flowers. And they have “only” had to build one of the largest photovoltaic plants in America on top of it, next to Guanchoi in Chileto achieve it. Threecorner milkvetch. It is a creeping plant that has curious needs: it only grows in sandy soils of the Mojave Desert. However, it is dependent on rainfall because its seed remains dormant in the soil and only germinates and reproduces with favorable rainfall. In dry years, it remains completely unnoticed, waiting for a little rain. And it is so rare that the species remains under evaluation for status as threatened or endangered under U.S. Fish and Wildlife Service regulations. In the same desert there is another threatened species: the desert tortoise Gopherus agassizii. The habitat of the two species should be the last one on which it would be decided to build a photovoltaic plant, but there is the Gemini Solar Project. The plant Megaplant. When such an installation is to be carried out in the desert, a technique known as clearing and leveling is used. In essence, all vegetation is removed, the land is leveled and prepared for install the pillars of the solar panels. Not only is a lunar landscape created, but any type of latent seed beneath the surface, such as that of the threecorner milkvetch, is destroyed. However, the Gemini Solar Project’s approach was different. The company wanted the land because it is especially ‘fertile’ within the US to harvest sunlight, but concessions had to be made. One was to minimize the alteration of the habitat of both species to conserve the desert surface with all its biological resources, preserve the topsoil and adapt the facility to the natural relief. On the US Geological Survey website we can see photos of little turtles between the panels. Works. This is part of what we know as ‘ecovoltaics’, with a branch called ‘agrovoltaics’ that we have also talked about and that, although it can be used by companies as a facelift, it serves to unite energy activities with agricultural activities. In the study on the impact of the Gemini Solar Project and the evolution of the plant, researcher Tiffany Pereira discovered what we have mentioned: there were more plants and they were healthier. This showed that the energy company had done its part by not destroying the soil because the seeds had been able to germinate, but they found something else. The plants inside the installation evolved earlier than those outside it and grew not under the panels, but in the strips between the rows. This implies that they still need intense sunlight to mature. The yellow zone is where the Sun shines the most hours. The blue one is the stripe that varies depending on the position of the Sun. The red one is where direct light never shines. Okay, but then… what is the role of the panels in the improved evolution of these plants? The hypothesis used by the researchers is that the panels provide partial shade on the groundslowing down evaporation. We have already said that seeds are dormant until they have the necessary humidity conditions to germinate, and in this context, a more humid microclimate has allowed plants to grow more and produce more seeds. Not all the field is oregano. Now, like almost every scientific study, we look at the other side of the coin. The rainfall in recent years has been favorable and we will have to see what happens with periods of prolonged drought. In a few years we could talk about long-term effects. But, in addition, this absence of plants under the panels could indicate a possible loss of potential habitat in very humid years. In any case, Pereira’s study is not isolated. Other studies point to improvements in both the number of flowering plant species and pollinators in agrovoltaic installations in a state like Minnesota. AND in China there are also indicators that those photovoltaic plants in deserts is contributing to the moisture pocket construction in which plants can thrive more easily. As we said, it remains to be seen the impact of the panels on the creation of a “new” biodiversity in the long term, but for now, what is evident is that it is not necessary to raze land to build a photovoltaic plant.

the Great Trade Route through the Mongolian Desert

by

At the end of the 19th century, as Japan emerged as an imperial power after the Meiji erahis army undertook an ambitious cartographic project to precisely know the territories beyond its borders. Those maps, prepared by the Imperial Japanese Army with methods that combined espionage, foreign sources and field work, were classified as state secrets and for decades remained hidden in military and university archives. Today, those maps have revealed a fascinating route. A forgotten runner. For centuries, the so-called Great Mongolian Route was a key artery of Eurasian tradean east-west route that crossed southern Mongolia connecting northern China with Central Asia and beyond, serving as a northern alternative to the better-known routes of the Silk Road. Despite its historical importance, it had been blurred between travelers’ stories and scattered references, without precise cartography that would allow it to be reconstructed in detail. That gap is what is now filled through a historical work, a published study in the Journal of Historical Geography by Chris McCarthy and his colleagues demonstrating for the first time that the Great Mongolian Route was not a literary abstraction, but a perfectly structured corridor, designed to enable the regular transit of camel caravans through some of the most arid and hostile landscapes on the continent. Military maps as secrets of the past. The researchers behind the discovery say that the key to rediscovering the Great Mongolian Route has been in the gaihōzuthose maps prepared by cartographers of the Imperial Japanese Army between the end of the 19th century and the Second World War, which systematically covered vast regions of Eastern and Inner Asia. Conceived with strategic and classified purposes For decades, many were on the verge of disappearing after the war (there were instructions to destroy them), but some were saved quietly and ended up in university archives that little by little became accessible to the public. Gaihōzu W6N2N map panel: Explaining the maps. The maps were not simple military sketches: they synthesized information from Chinese records, ancient Russian uprisings, and, in some cases, Japanese field work, resulting in a surprisingly accurate representation of routes, wells, monasteries, oases and geographical features key to survival in the Gobi Desert. Owen Lattimore’s map of several Inner Asian caravan routes, including the Great Mongolian Trail, whose name appears next to the location of Gurbun Saikhan Confirm the map on the ground. Recent work has gone beyond the archive, touring more than 1,200 kilometers on the ground to verify to what extent those sheets coincided with current reality. The verification has confirmed about fifty nodes (from water sources to settlements, caves and sacred places) spaced at intervals of about 24 kilometers, a distance that fits exactly with the average day of a camel caravan. Plus: the oral traditions of local shepherds, the physical traces of secular transit and the persistence of toponyms have reinforced the idea that these maps captured a refined logistical system, one in which each stop was essential to making the journey possible. Gaihōzu W9N2N map panel Caravans, tea and benefits. Although the main objective has been to document the infrastructure of the route, everything indicates that was parte of the historic tea trade, with Chinese goods traveling west and steppe products returning east. Inscriptions found in caves and oases speak of journeys of up to 120 days for heavy caravans and faster journeys, of about 90 days, for urgent transports seeking extraordinary benefits. The harshness of the route did not deter the merchants, moved by the promise of “triple benefits,” a reminder that these routes were not only avenues of cultural exchange, but high-risk economic gambles. From stories to cartography. For decades, knowledge of the Great Mongolian Route depended almost exclusively on the descriptions of the explorer and scholar Owen Lattimorewhose diagrams offered a conceptual vision of the corridor. Now, the combination of his stories with the millimeter detail of the gaihōzu transforms that diffuse image into a concrete and verifiable layout, where each lake, well or monastery has a clear function. The result not only recovers a lost route, but shows to what extent these military maps constitute an exceptional file of landscapes, economies and ways of life just before modern transportation erased centuries of mobility caravan in the interior of Asia.

For thousands of years, human beings have avoided crossing the Taklamakan Desert. Now China is raising fish there

by

For more than 1,500 years, the merchants who traveled the Silk Road dared with oceans, mountains and jungles, they dared with endless walks, with warlords, with hunger and pain and the cold; with one of the most destructive epidemics in history; but they did not dare with the Taklamakan. That sand hell (whose name comes from the word ugiur for “abandon, leave alone, leave behind”) is not only the second largest dune desert in the world, but it moved, invaded and devoured everything around it. It’s been a nightmare for thousands of years. Well, now, China is farming fish right there. As? As it sounds, Xinjiang has been committed to producing fish and seafood “in the middle of the desert” for years. And no, obviously, it has nothing to do with “releasing fish in the sand” as if it were worms from Arrakis. The key is saline-alkaline water, lined ponds and recirculation techniques. It is not a revolutionary approach (already We have talked about similar techniques), but without a doubt Chinese producers are taking it to another level. Xinjiang aquaculture production was 196,500 tons in 2024. And, of course, the “desert seafood” boom raises questions about water, energy and scalability. From the promise of fresh fish… We are talking about a very harsh physical context (annual rainfall of less than 100 mm, very high evaporation and salinized soils): thus, the entire Tarim sub-basin depends on melting snow to provide water. Therefore, on the table, there are two clear approaches: the first, which has become popular in the Westtalks about the construction of monitored ponds. And this is already, in itself, very effective: “species such as grouper, mullet, shrimp, oysters and pearl musselsyes reach commercial size with survival rates close to 99%”, always according to the available data. But that’s just the beginning; just a proof of concept. …to the promise of mar. As explained by several chinese mediathe final horizon of the project is much more ambitious: creating a sea in the middle of the desert. That is, take advantage of the water associated with saline-alkaline soils and saline lakes to simulate marine conditions with technical adjustments, circulation systems and cultivation of microorganisms. And thus be able to breed species normally linked to the sea. But can that be done? Of course you can. We have the technology to do it. In a world where aquaculture already exceeds extractive fishing in volume, the interesting question is not that: the question is whether the model is scalable without aggravating tensions over water in a hyper-arid region dependent on snowmelt. What the industry that sees tons of fish emerging from the desert is asking is something even more basic: is it possible that the beginning of the end of commercial fishing is beginning?

240 km without curves, in the middle of the desert and with truck traffic

by

Imagine driving for more than two hours without turning the steering wheel even a single degree. No curves, no noticeable slopes, no changes on the horizon. That is the reality of Highway 10 (Highway 10) of Saudi Arabia, which holds the Guinness record as the longest straight road on the planet with a completely linear section of 240 kilometers. A highway born for a king. Highway 10 stretches 1,480 kilometers from Ad Darb to the border with the United Arab Emirates, but it is its segment between Haradh and Al Batha that has received all the attention. The road was originally built as a private road for King Fahd of Saudi Arabia, although today it has become a fundamental artery for the transport of goods between the center and west of the country with the Emirates. The Empty Quarter desert as a setting. The road crosses the Rub’ al Khaliknown as the Empty Quarter, the largest sand desert in the world. The area itself explains why it is possible to build such a straight line: there are no mountains to surround, valleys to cross or geographical features to avoid. Just sand and more sand as far as the eye can see. The infrastructure is completely paved and has mainly two lanes in each direction, supporting intense truck traffic that crosses the desert. Speed ​​limits adjusted for heavy traffic. The maximum speed allowed on this highway varies depending on the type of vehicle: passenger cars can travel up to 120 km/h on fast sections, buses 100 km/h and trucks 80 km/h. Although in 2018 were announced Upper limits of up to 140 km/h for light vehicles in certain sections, the constant presence of heavy transport makes maintaining these speeds complicated in practice. A mental challenge more than a physical one. Believe it or not, driving on the straightest road in the world is not as easy as it seems, especially due to fatigue. The monotony of the desert landscape and the total absence of visual stimuli can cause drowsiness and even a dangerous disconnection while driving. Added to this is the occasional threat of camels wandering across the road. So, although the route is ‘easy’ to handle, mentally it can become a nightmare. Not for nothing is it found in Dangerous Roads website. Reinforced security measures. Aware of the risks involved in driving on such a monotonous road, the Saudi Ministry of Transport and Logistics has implemented various improvements safety features, including paved shoulders, reflective pavement markings (known as “cat’s eyes”), protective barriers, kilometer signs, and directional and warning signs. Here the driver’s attention must be vital, especially on a road with so few changes. Other legendary straights. Before Highway 10 snatched the title, the Australia’s Eyre Highway boasted the record with a 146 kilometer straight stretch through the Nullarbor Desert. Although almost 100 kilometers shorter, this Australian road remains one of the most unique driving experiences on the continent. Also noteworthy are roads such as ND-46 in North Dakotathe United States, or some sections of the Argentine Route 40which although they do not compete in length of absolute straightness, offer endless kilometers of visual monotony.

China has a gigantic desert in Tibet with countless hours of daylight. And he’s filling it with solar panels

by

A year ago we had in Xataka how a huge solar park in the Chinese province of Qinghai, in the heart of the Tibetan plateau, served as an ecological experiment: under the panels, the shade retained moisture and made vegetation sprout in the middle of the desert. Today, that same place – the Talatan Solar Park – has become something much greater. It is the largest clean energy facility on the planet, a “blue sea” of silicon that already covers more than 600 square kilometers at three thousand meters above sea level. Where before there was nothing, China is lifting an energy ecosystem without comparison in the rest of the world. The scale has multiplied. Where last year there was talk of a 1 gigawatt solar park, today a complex extends that reaches 15,600 and 16,900 megawatts and continues to expand. Its area – between 420 and 610 square kilometers – is seven times that of Manhattan. Furthermore, it is not alone since 4,700 megawatts of wind energy and 7,380 megawatts of hydroelectric dams are deployed around it, completing an unprecedented hybrid system. The result: enough renewable energy to supply almost all of the plateau’s needs, including the data centers that power China’s artificial intelligence. According to CleanTechnicaevery three weeks China installs as many solar panels as the entire capacity of the Three Gorges Dam, the largest hydroelectric project in its history. A global clean energy laboratory. The Tibetan plateau, with its pure, cold air, has become the most ambitious energy laboratory in the world. There, China is experimenting with an electricity production model based exclusively on renewables. Electricity generated in Qinghai—40% cheaper than coal, according to the NYT— powers high-speed trains, factories, electric cars and data centers. In fact, the region is home to new computing centers dedicated to artificial intelligence, which consume less energy thanks to the altitude and low temperatures. “Hot air from servers is used to heat other buildings, replacing coal-fired boilers,” explained Zhang Jingang, vice provincial governor. In the words of Professor Ningrong Liu, in his column for the South China Morning Post: “China is not only leading the transition to green energy; it is building the 21st century energy scaffolding that sustains its industrial leadership in electric vehicles, batteries and solar technology.” Three sources that beat in unison. The magnitude of the project is only possible thanks to centralized planning that combines three main sources: solar, wind and hydroelectric energy. During the day, Talatan panels capture more intense solar radiation than at sea level; At night, thousands of wind turbines collect the cold breezes that sweep across the plains. When both systems fluctuate, hydroelectric dams balance the grid. Also, from the New York Times They described a system reversible pumping: excess solar energy during the day is used to raise water to reservoirs located in nearby mountains, which release that water at night to generate electricity. And under the panels, life returns. The shade of the plates reduces evaporation and soil erosion. According to China Dailythis year the vegetation has recovered up to 80% and 173 villages have benefited from the associated livestock farming. A local shepherd, Zhao Guofu, said: “My flock has grown to 800 sheep and my income has doubled since I grazed between the panels.” The perfect geography for the sun. No other country has taken solar generation to similar altitudes. The altitude plays in favor of physics, at 3,000 meters the air contains fewer particles that block light and the low temperatures reduce the thermal loss of the panels. This efficiency is multiplied in Qinghai, one of the few areas of the Tibetan plateau with large plains, where it is possible to build without the limits of the mountainous relief. The Talatan Desert, once an arid and worthless land, has become an energetic jewel. local authorities offer symbolic leases and have developed roads and high-voltage lines connecting the plateau with the industrial centers to the east. That energy travels more than 1,600 kilometers to factories and cities. According to CleanTechnicaChina already operates 41 ultra-high voltage transmission lines, some longer than 2,000 miles and up to 1.1 million volts. The global scale: no one comes close. Other countries have tried to generate clean energy at altitude, but with modest results. Switzerland, for example, inaugurated a small solar park in the Alps, at 1,800 meters, with barely 0.5 MW. For its part, in the Chilean Atacama Desert, a 480 MW project operates at 1,200 meters. By way of comparison, the Talatan complex multiplies the capacity of the Bhadla Solar Park in India, and for more than seven that of the Al Dhafra Solar Park in the United Arab Emirates, which until recently held records. The superpower of clean energy. China produces and consumes more renewable energy than any other country on the planet. In 2024, was responsible of 61% of new solar installations and 70% of global wind power. That same year, it achieved the capacity targets it had set for 2030. In the first six months of 2025added 212 GW solar and 51 GW wind, and the country’s carbon emissions fell for the first time. In this context, Talatan Park is both a symbol and an infrastructure. China is exporting its renewable technology around the world, from Asia to Africa, following the logic of Belt and Road Initiative. For the academic Ningrong Liu: “China wants to stop being the world’s factory to become the engine of the world’s factory.” It is not just about manufacturing panels, but about selling the complete model: engineering, financing and know-how to build green networks in other countries. The less visible side of the miracle. It’s not all clean energy and pastoral harmony. In its report, The New York Times recalled that access to Tibet remains strictly controlled by the Communist Party, and that Western media were only allowed to visit Qinghai on a government-organized tour. There are also human and environmental costs. CleanTechnica documents how the giant power lines that transport energy from west … Read more
