by

Renfe celebrates the 40th anniversary of one of his most emblematic tourist trains, the Al-Andaluswith a great renovation for its 2026 season. With this exclusive luxury train, Renfe climbs into the “Slow Luxury” rebirth car that are promoting international luxury operators such as Belmond Train, owned by LVMH, with proposals for proposals for more rest and exclusive trips aboard of the Orient Express or the Britannic Explorer. A luxury train to the heart of Andalusia. In its proposal by 2026, the Al-Andalus expands its route to include Historical and cultural destinations from Extremadura, Castilla-La Mancha and the Community of Madrid, offering an exceptional trip inspired by the elegance and glamor of another era. This “Orient Express” Spanish It moves passengers to another era full of luxuries and sophistication, but in which everything develops at a slower pace, in contrast to the speed at which the current world moves. That is precisely the experience of traveling on this exclusive train, to enjoy the journey as much as the destination. New route for 2026. The 2026 route is an invitation to discover the patrimonial and gastronomic wealth of the south and the interior of the Peninsula. For seven days, Al-Andalus travelers travel Andalusia, Extremadura, Castilla-La Mancha and Madrid, with stops in such emblematic cities such as Jerez, Cádiz, Sevilla, Córdoba, Toledo, Aranjuez, Cáceres, Mérida and the Spanish capital. This journey maintains the classical duration of seven days and six nights on board, where time passes between fascinating landscapes, cultural stops and an atmosphere that revives the elegance of the early twentieth century. Comforts and luxury services on board. The Al-Andalus train is the longest train that circulates along the Spanish roads, with 450 meters long, equivalent to a skyscraper of 150 plants. It consists of 14 cars that house a total of 64 passengers. Among its amenities are a kitchen car, two restaurants, a bar, a game room and seven beds to rest with all the Comodities of a luxury hotel.

China has broken the dependence of the GPS in two decades. His proposal has already convinced 140 countries

by

China has just published The data of your satellite navigation system (Beidou) for 2024. After the figures a geopolitical transformation is read that has not made much noise but that is full of meaning. Why is it important. The United States controlled global satellite navigation through GPS. China has created a viable alternative in just twenty years, breaking its own agency and also offering options to other countries. Beidou began as a Chinese military project in the 1990s. Today it is recognized by the United Nations as a global satellite navigation provider, integrated into eleven international organizations. In figures: The Chinese satellite navigation sector invoiced 79.9 billion dollars in 2024. That is 7.4% more than in 2023. Beidou processes more than one billion daily location requests (it is not a False Friend: one billion). And guide 4,000 million kilometers of navigation every day. Besides… 288 million Chinese mobile phones already integrate Beidou. The system covers 99% of urban and rural roads in the country lane precision. Yes, but. Beidou has not displaced GPS as a dominant global standard. Most current devices use several satellite constellations (GPS, Beidou, Galileo, Glonass) to improve precision and reliability. The 140 countries that use Beidou do it mainly as a complement to GPS, not as a total substitute. And they adopt it differently: More than 30 African nations They have installed continuous reference stations for high precision services in agriculture, water management and weather monitoring. In Latin America, ports like Chancay’s in Peru They integrate Beidou In smart navigation systems. In Asia and the Middle East, several countries use Chinese constellation to complement transport and logistics services. The majority does not completely replace GPS, but adds Beidou as a second option to reduce dependencies or improve coverage in regions where US signals are weaker. One of Beidou’s strengths is his best coverage in the southern hemisphere. In 2020 he completed his global scope. Between the lines. China has not defeated GPS, but has achieved something equally valuable: reduce its critical technological dependence. The United States can no longer cut access to satellite navigation as a diplomatic weapon against China. And now what. Beidou marks the Chinese patron: not completely replace Western systems, but to create viable alternatives that reduce strategic dependencies. Not to compete, but build your own parallel reality. As Huawei has doneamong others. Satellite navigation is only the beginning. China replicates this strategy in 5g, AI and renewable energies. In Xataka | China is turning its roofs into power plants.

The amazing proposal of the Emirates-Indian Tunnel

by

When the United Arab Emirates is treated, the pulse does not tremble. There are to prove it Burj Khalifathe largest skyscraper on the planet, or projects such as the Luna -shaped resort of Dubai u One Za´abelendowed with the largest cantilever building ever built. Any of the three pales if compared, however, with the structure proposed by National Advisor Bureau Limitedcompany based in MASDAR. A gigantic underwater tunnel that would cover around 1,800 kilometers that separate two port areas from Arab Emirates and India. The infrastructure is in the concept phase, but stands out for its ambition, dimensions … and the interesting possibilities that it would open in the region. What does it propose? A draft mega -structure. The proposal by National Advisor Bureau consists of building a huge submarine tunnel that allows direct United Arab Emirates (EAU) and the remaining countries that make up the remaining. Cooperation Council of the Arab states of the Gulf – organism that integrates half a dozen nations from the Middle East – with India. To be more precise, the project is drawn between two coastal points separated by about 1,800 kilometers: Fujairah and Mumbaion the west coast of India. And what would the duct be like? Submarine, drawn under the waters of the Arabic sea and entering the Gulf of Oman. To better illustrate the infrastructure in mind, National Advisor Bureau elaborated several years ago A series of videos and infographics in which the proposal clearly appreciates: formed by two concrete ducts that pass in parallel and remain submerged, although in suspension, tied to a series of floating structures. Another alternative would go to tie them with fasteners to the bottom of the sea. The idea of ​​its designers is to keep the tunnels at a depth that does not interfere with maritime traffic and keep them safe from inclement. His pontoons would also be separate enough to allow the passage of surface ships, through the waters of the Indian. As for the tubes, they would be built to be resistant to the corrosion of salt water and pressure. What would the tunnels be used for? For the transport of passengers, tourists and workers who wish to move between United Arab Emirates and India, but also merchandise and strategic supplies. The infographics of National Advisor Bureau show that each duct would be divided in turn into four large compartments: one for trains, another for goods and two lower, as a pipes, which would be dedicated to oil or gas and water flow. The objective is to export oil from the Emiratí port of Fujairah to India through the pipeline and import the excess water of the Narmada river, north of Mumbai. Its authors argue that Narmada usually overflows during the monsoon season. The project does not rule out that oil or gas can be used beyond India, China or Pakistan, or the construction of a floating fuel station to supply ships between pontones. What kind of train do we talk about? One fast. Very fast. The authors of the project explain that within the tunnel a vacuum would be created that would allow the use of “ultra -granted” railroads, capable of reaching speeds between 600 and 1,000 kilometers per hour (km/h). It is an ambitious objective, taking into account that Chinese Maglev trains point to 600 km/h and 1,000 km/h It is the objective of its modern Hyperloop, still in the test phase. Since the distance between Mumbai and the Fujairah station is around 1,800 kilometers, the journey could be made between two and four hours. The company even speaks of another possible route, between Fujairah and the port of Gawader, in Pakistan, that the submerged infrastructure would allow to cover in one hour. At what point is it? In the concept. The idea was released a few years ago National Advisor Buerau, behind others equally media projectsas UAE-Fergwhich raises IACEBERGS towing From Antarctica to the coast of Fujairah to take advantage of them as new fresh water sources in the region. The proposal of the submarine tunnel began to sound before the pandemic, towards 2018 either 2019as a concept, and achieved attract interest of International media. Since then his information flow has gone less. Of one of the latest news They echoed in 2021 #Swajya or India Infrahubwho collected how Abdulla Alsehhi, director of Nationa Advisor had defended the advantages of the structure in a strategic conclave focused on relations between Arab Emirates and India. The entrepreneur and engineer The potential stands out of the submarine project to improve bilateral trade between both nations.

Cruises will save a lot of fuel through the sun through their balconies: a new German proposal

by

Solar balconies have proven to be effective in terms of self -consumption in countries such as Germany, Netherlands And even Spain. But what would happen if we took them to the middle of the sea? Not in the form of floating panels, but integrated into a cruise. A cruise with solar panels. An investigation has developed A simulation to check the installation of photovoltaic in the cruise cabin. The objective of the project is to feed public services and, at the same time, reduce the environmental impact. The initiative raised by the German Aerospace Center (DLR) and Siemens Energy Global have taken cruise data that navigated the Caribbean already along the Norwegian and Danish coasts. These routes were not randomly selected: the differences in solar radiation between tropical and northern European regions offered an ideal range to evaluate the performance of photovoltaic systems in very different climatic conditions. The design. The study has raised a system that integrates solar panels of 250 W and 22 % efficiency in the boots of the cabins. In addition, each cabin would be equipped with two panels: one integrated into the glass barrier of the balcony at an angle of 90 ° and another placed at an angle of 30 °, between the ship’s covers. The scientists themselves have explained that if a cruise of the Helios class with 1,655 shots with balcony is extrapolated, in terms of scalability the maximum photovoltaic capacity would be at 827.5 kW, which is a significant step towards a cleaner energy in high high sea. The networks. Currently, cruises are adopting continuous current (CC) networks to facilitate the integration of renewable energy sources. In each case, the researchers evaluated three integration approaches for solar panels. First, a network of 48 volts, which directly feeds the cabins, but its high cost and maintenance makes it less practical. On the other hand, the 350 volt network, which acts as a secondary distribution network, balancing security, efficiency and operational simplicity. Finally, the 700 volt network, which connects with the machine room to be a primary network, but has greater energy losses. After evaluating these options, researchers have concluded that the 350 V network combines security measures, lower cost and simplicity in maintenance for the integration of panels into the balconies. In addition, the system is complemented by iron and lithium phosphate batteries (Lifepo4), specifically designed to store energy in case of emergency, cushion demand peaks and guarantee a stable supply. The results. Scientists have performed simulations with Python taking into account more than 100 energy demand scenarios in the cabins during two cruise routes: a 15 -day tour of the Caribbean in March and an eight -day route along the coasts of Denmark and Norway during the months of August and September. With that recreation they have discovered that photovoltaic systems managed to cover 45% of the needs in the Caribbean and 47% in northern Europe. As for energy savings, it was an average of 3.2 MWh in the Caribbean and 3.8 MWh in Norway and Denmark. Finally, the environmental impact would reduce CO2 emissions between 1,500 and 1,800 kg per day, depending on the route. Other boats with solar panels. The study not only highlights the potential of solar balconies to improve the energy efficiency of cruises, but also ask questions about their scalability and future applications. However, it is not the first time that we see solar panels in ships, we have already seen progress in future candles with photovoltaic and, even, there are many millionaires who They bet on ideas more sustainable. Despite being a sector that It presents challenges For the autonomy of their batteries or the lack of load infrastructure, but this German idea in the cruises promises to open new possibilities of high seas efficiency.
