The German Wendelstein 7-X reactor has broken all records

by

In the field of nuclear fusion ITER (International Thermonuclear Experctor reactor), The experimental reactor that an international consortium led by Europe is building in the French town of Cadarache, monopolizes all eyes. However, in the old continent we have other fusion energy machines that are also very important. The Wendelstein 7-X experimental reactorwhich is installed in one of the buildings that the Max Planck Institute has for Plasma Physics in Greifswald (Germany), is one of them. Its purpose is to contribute to the development of the technologies involved in the tuning of nuclear fusion reactors through magnetic confinement, but its formula is different from that proposed by Iter or JET. In fact, the Wendelstein 7-X reactor is a type design Stellarator. The most obvious difference between Tokamak and Stellator reactors It resides in its geometry. The former have a toroid form (or donut), and the latter have a more complex geometry that resembles them to a twisted donut on itself. However, the fundamental difference between these two designs is that the reactors Tokamak They require that the magnetic fields that confine the plasma are generated by coils and induced by plasma itself, while in the reactors Stellarator Everything is done with coils. There is no current within the plasma. This means, in short, that the latter are more complex and difficult to build. Fortunately, Wendelstein 7-X experiment is already delivering extraordinarily promising results. Global record in long -term plasma The first tests carried out in this fusion reactor between 2015 and 2018 came out as planned, so in November of this last year there came an important moment in its itinerary: it was necessary to modify it to install a water cooling system that was able to evacuate more effectively the residual thermal energy of the walls of the vacuum chamber, as well as a system that allowed the plasma to reach a higher temperature. The works required by these modifications concluded successfully in August 2022. The electronic cyclotonic resonance heating system delivers more than 1 MW of power to plasma When scientists introduce such important modifications in such a complex experiment they are forced to review everything obsessively before launching the machine again to make sure that everything will go correctly. Fortunately everything went well and in February 2023 the Wendelstein 7-X reactor reached an important milestone: He managed to confine and stabilize plasma for 8 uninterrupted minutes in which the reactor delivered a total energy of 1.3 gigajulios. But it wasn’t enough. Now it was time to submit this machine to a new maintenance and renewal phase with the purpose of going further. A year later the reactor was prepared again to carry out new experiments, and now has significant improvements. The technicians who have worked on it in recent months have optimized the control and data acquisition systems, have improved the plasma heating system and have implemented about 50 additional diagnostic tests. Of all these improvements the most relevant is the heating system because it is now capable of generating more than 1 megavatio of power in the plasma thanks to the microwave application. This technology is known as the electronic cyclotonic resonance heating system (ECRH or Electron Cyclotron Resonance Heating in English). The first results have not taken to arrive. And it is that on May 22 this German reactor registered a world record by sustaining the fusion reaction through a high performance plasma For 43 seconds. To date, no other merger machine has prolonged both the triple product in long -term plasma discharges. Understanding what the triple product is is not difficult (it is also known as Lawson’s criteria). In fact, it is nothing more than a metric that evaluates the density of the plasma particles, its temperature and the time that magnetic confinement lasts with the purpose of measuring the performance of the fusion reaction. This strategy is essential because it allows engineers to determine if the fusion reactor has overcome the threshold that allows it to generate more energy than it has been necessary to use to heat the plasma. Once this point has been reached, the energy balance becomes positive and the fusion reaction can be sustained over time without investing energy in the heating system continuously. This milestone would not have been possible without the intervention of the new frozen hydrogen packages developed by the Oak Ridge (USA) National Laboratory. However, there is something else that is worth not overlooked: during the campaign that the reactor has just finished, he has delivered 1.8 gigajacles of energy, so he has clearly exceeded the 1.3 gigajulios that he reached in February 2023.

If the question is which car will not leave you lying on the road, the German experts are clear: the electric

by

More and more drivers They bet on electric cars And, with it, the Reports about your reliability They become more precise and complete because they provide more real data on the wear of their pieces over time. He last analysis of the ADAC, The main automobile club in Germany has thrown surprising data on the frequency of roads on the road, comparing electric and combustion vehicles. We have a clear winner. Thrown on the road. He ADAC studymade from millions of road assists, reveals that electric cars have a lower breakdown rate than their fuel or diesel combustion counterparts. This data is essential for those looking for a reliable car and with less possibilities of stay on the road. The analysis is based on 3.6 million road assistance operations, of which only 43,678 went to electric cars, which represents only 1.2 % of the total. Although the percentage of electric cars in circulation is much lower than that of combustion cars, the fault ratio remains well below compared to the thermal models of the same antiquity. The data leave no doubt. Adac data has only taken into account cars of which, at least, 7,000 units have been enrolled in Germany in the last two years, which leaves a sample of 160 models of 20 brands other than two and nine years old. If vehicle data is compared four years old, the Road Assistance Service It served 8.5 electric cars damaged by every 1,000 existing cars, compared to 12.9 combustion cars per 1,000. For cars between two and four, the difference is even greater: a ratio of 3.8 breakdowns per 1,000 electric versus 9.4 per 1,000 combustion cars. These numbers show that the electric ones fell half that the thermal models. A simpler mechanic, less breakdowns. The main reason for this difference lies in the Mechanical simplicity of electric cars. Having less mobile components and mechanical systems, there is less likely to suffer a breakdown that requires road assistance. For example, electricity do not have traditional gearbox or complex exhaust and cooling systems, which significantly reduces critical fault points. However, the most common breakdown in both types of vehicle remains the 12V auxiliary battery that tends to be downloaded more easily due to use in starting systems and the greatest demand for electronic systems. In the electric, 50% of the faults are related to this component, while in combustion the 45% of the assists. Tesla leaders, Hyundai to the tail. The ADAC report also analyzes reliability by brands and models. The data show that Tesla is the brand with less incidents registered. Thus, the Tesla Model and has a ratio of only 0.9 breakdowns per 1,000 units and Model 3 drops to 0.5 faults per 1,000. Other highlighted models in this section are the Volkswagen ID.4 with a ratio of 1.0 and the Audi Q4 e-tron with 0.7 failures per 1,000 vehicles. On the opposite side, as a vehicle with more registered assists, there is the Hyundai Ioniq 5, which in two -year -old cars has registered 22.4 breakdowns per 1,000 vehicles. Discordant notes. Toyota, considered one of The most reliable brands In different reliability rankings, it obtains a alarmingly high assistance ratio in its Yaris and Yaris Cross models. According to the study authors themselves, Toyota has already taken letters in the matter indicating that it is an incidence in the 12V battery configuration that discharged them, but that was solved in the new units produced in 2024. The data obtained by ADAC contrast with the Obtained in the Itv German (Tüv), where the Tesla Model 3 was the electric with the most failures detected, especially in headlights, brakes and suspensions, being below brands such as Dacia in general reliability according to this organism. The electric approve with note. The electric car market is relatively recent, so Adac clarifies that its conclusions are based on data data with an age of between 2020 and 2023, many of them being the first versions of their models. That leaves a current photograph but still limited in time. As increase the electric car park and These vehicles agethe records will be increasingly precise and complete, allowing to detect problems of long -term reliability. However, these results already allow an idea of ​​the reliability offered by the electric car and the evolution it will have in the coming years.

GTD dropped the German rocket Spectrum to the sea during Sunday launch

by

Isar Aerospace declared successful the launch of your Spectrum rocket To the north of Norway, but it was a Spanish company that saved the day in some way. Context. The German company Isar Aerospace tried to launch the first private orbital rocket in Europe on Sunday. After lighting the nine engines of its first stage, the Spectrum rocket cleared the launch platform, located on the island of Andøya, north of Norway. 18 seconds later, Spectrum began to turn and correct its orientation orientation. Half a minute had passed from takeoff when the engines turned off and the rocket fell into the sea. The 28 -meter pitcher, loaded with propane and liquid oxygen, finished his inaugural flight with a great explosion. The Spanish contribution. GTD, an engineering consultant based in Barcelona, ​​was in charge of Develop the launch control system (LCS) of the Andøya Space Puerto. This system supervises the countdown and flight safety of the Spectrum Spectrum of Isar Aerospace. His role was fundamental in the rocket debut. Not only because the countdown worked perfectly, but because it successfully activated the flight termination system that made the rocket safely to the sea. Flight termination system. Unlike other rockets, Spectrum does not call themselves when something goes wrong. Its flight termination system (FTS) consists of turning off the engines to prevent the rocket from getting out of its trajectory and, instead, falls controlled into the sea. The software of the Spanish company GTD He successfully activated the flight termination system when the rocket lost control. The rocket turned off its engines and began to fall, without causing damage to the launch platform. “We are proud to have demonstrated the reliability of our systems in such a symbolic mission for Europe in space,” Ricardo Bennasar, Coo by GTD, said in a statement. “It is a key step for future missions, and we are ready to continue supporting what is coming.” The congratulation. Isar Aerospace congratulated the Spanish company privately for its role in launch. “We were able to validate our flight termination system,” He said his CEO publiclyDaniel Metzler, Sunday. Although the system is designed for exceptional situations, its correct execution is one of the many data collected by the German company for the second flight. Metzler has commented that Now they know “the double” What they knew before trying the rocket, in addition to confirming that the second and third Spectrum pitcher are already in production.

How a German submarine cable is threatening to change energy control in Spain

by

European energy infrastructure is one of the more interconnected in the worldone in seven electricity units It is marketed through terrestrial and submarine cables. However, electrical networks They need more connections and improvements to guarantee stability and energy safety. Now, a German company has decided to challenge the monopoly structure of Spain. German initiative. The Europe Link Development Company has proposed Apollo-Link, a project to create underwater interconnection between Spain and Italy. From the project page They have explained that it is an alternative to continue promoting networks in Europe and more in A context of energy crisis. In this way, the initiative would allow Italy to reduce its energy dependence and take advantage of the renewable energy of Spain. Connection so far. Currently, the interconnection of Spain with the rest of the EU countries is done through France, except with Portugal. The Spanish electricity grid has exclusivity in the transport of electricity, so the German project will challenge the monopoly structure. However, there are exceptions for private international interconnection projects that can be described as “Merchant Lines”. Merchant Lines. European legislation allows third parties outside of transport networks (TSOS) to develop international interconnections under the “Merchant Lines” regime, which is eximicated from the regulations of the Spanish electricity sector. However, these projects must meet certain requirements, and the technical-economic viability of the interconnection must be demonstrated. Despite the possibility of these private projects, the TSO always have preference to execute projects that conform to the official network planning. Economic impact. As The economist has been able to have accesswithin the energy sector they have warned about the implications of this project. While Italy would benefit from Spanish renewable energy, on the other hand Spain would experience an increase in electricity prices due to the greater exchange with other countries. The negotiation of economic terms and the distribution of benefits and costs will be crucial to avoid disadvantages for the country, as already It happened in full crisis of 2022. In addition, before the implementation of the project, thorough studies must be carried out to evaluate its impact on the networks of both countries. What will it consist of? Europe-Link Development has mentioned which seeks to facilitate the exchange of electricity between Spain and Italy. The objective is to link the electrical systems of both countries through an underwater cable of 660 kilometers and an exchange capacity of 2,000 MW. However, it is in a preliminary phase and needs the approval of the managers of the electrical networks of Spain and Italy, Electric and Terna, respectively.

A Peruvian farmer has seen a glacier from the Andes melts. So he has brought a German energy to trial

by

The Peruvian farmer Saúl Luciano Lliuya has observed how Lake Palcacocha grows every year in Huaraz. This situation has caused the farmer issue for the overflow of the lake and ends affecting his community. However, instead of resigning, he has decided to take those responsible for this situation to court. An unprecedented case. Saul Luciano Lliuya has sued the RWE energy company before the German courts. In its demand, Lliuya has argued that this company is the one that emits the most issuance contributing to climate change, accelerating the melting of glaciers in its hometown, putting its habitability at risk, according to has collected Associated Press. The demand. Supported by the activist group Germanwatchthe Peruvian farmer wants RWE to pay around 17,000 euros ($ 18,520) for a flood defense project, according to He has reported Reuters. 10 years ago. The filing of the lawsuit was in 2015 in Germany and, two years later, the courts accepted it, According to EFE. During all these years, evidence has been collected to determine whether there is a direct relationship between RWE emissions and the risk of flooding in Huaraz. In addition, the trial has prolonged because the German company has used legal strategies, arguing that the responsibility for climate change cannot be attributed to a single issuer, such as They have explained to Associated Press. The defendant. The energy company has denied its responsibility on multiple occasions. From the company, have affirmed for DW that climate change is a global problem caused by multiple factors and that it is not possible to legally attribute its effects to a single entity. In addition, for the same medium, they have declared that if there is such claim according to German legislation, all drivers should also be considered responsible, and that it is a socio -political error. The evaluations. Among the collection of information that is being gathered for the trial, there is a 2014 study conducted by Greenpeace and the Climate Justice Program, in which RWE held RWE for 0.47% of global greenhouse gas emissions since the beginning of industrialization. In addition, different researchers have shown that greenhouse gas emissions have a direct impact on the melting of glaciers in the Andes, such as have detailed in The Guardian. Regarding the glacier, this has been melting in these last 36 years for climate change, according to A study by Nature magazine. Although this is not the only evidence, another scientific research has shown that the water level in Lake Palcacoha It has increased Since 1990. This situation can raise the risk of an avalanche, similar to what devastated Huaraz in 1941 and caused the death of 1,800 people. The beginning of the trial. On Monday, March 17, the trial began and, As Efe has advancedthe lawyer of Lliuya, Roda Verheyen, explained that if sentence is issued in the next session, scheduled for April 14, the necessary precedent will be obtained to go after other great pollutants.

We have a problem with used wind blades. A German startup believes to have a solution: make them wood

by

At some point he had to arrive, because in the end, everything comes to an end, even the materials for renewable energy. First it was the turn of the solar panels, which now have Recycling centers. Then, it was the turn of the wind energy that their blades have found a second life in different structuresfrom mini homes even jelly beans. But so far, no one had achieved what he has achieved in the wind sector: starting from scratch with completely recyclable materials. 100% recycled. The German company Voodin Blade Technology has developed The first wind turbines made of laminated wood. This material has represented a recyclable alternative to the traditional carbon fiber, fiberglass and epoxy resin. In addition, the most curious thing is that it has greater fire resistance and a rigidity-pepper relationship similar to fiberglass, which allows you to resist all climatic conditions. As of 2026, the German company has been associated with the Indian company Senvion for install some blades of more than 50 meters In 4.2 MW turbines. The tests will be held in Europe at the end of next year and beginning of 2027. The goal. The German startup has found a rather big problem within the wind industry. While in the solar sector there are already recycling centers for photovoltaic panels, such as European photovoltaic recycling center (CERFO) In Teruel. I asked that it was around the company was: What about the wind turbines? The investigation took them to A study by the University of Cambridgewhich revealed that by the year 2050 there will be 43 million tons of shovels worldwide. The reason was none other than conventional materials are very difficult to recycle, so they reached the rolled wooden blades. This solution that is based on reuse to prevent them from ending up or are incinerated. In addition, the use of a natural material such as wood has a lower impact on the product life cycle, since it can be replaced and managed more responsible. Manufacturing. The process to get LAMINADA WOOD It goes on presses and laminating, as the name implies, wooden panels, creating resistant and durable materials. This type of wood is already used in the construction of skyscrapers and other important infrastructure, which demonstrates its reliability. Laminated wood offers a greater flexibility In the design, which allows to create longer blades and higher towers, optimizing the efficiency of the turbines by taking advantage of stronger wind currents. This advance not only provides a more ecological alternative, but also makes the production of blades more economical. In addition, in the manufacturing process eliminates the need for molds, which further reduces production costs, and makes the process more efficient and accessible. In fact, wooden blades can be up to 20% cheaper than traditional ones, according to The German company declared to Recharge. Although something if it had been recycled. While some advances have already been achieved in the recycling of traditional blades, the VOODIN BLADE TECHNOLOGY approach goes one step further. Although it should be noted that the Danish company Vestas has developed A chemical process capable of decomposing epoxy resins and then reuse in new blades, preventing them from ending in a landfill. And fire resistance? It is quite curious because they can even be replaced, but resist fire. In the first place, laminated wood can support high temperatures because being a natural material, it has a Greater self -extinguishing capacitywhich means that it is less prone to burn or spread rapidly in case of fire. In addition, advances in their treatment make it more lasting and stable in front of the fire. On the other hand, traditional materials, such as fiberglass and carbon fiber, although strong and light, do not have high fire resistance. In the end these components, together with the necessary resin to unite them, are more susceptible to decomposition and the release of toxic gases when exposed to high temperatures, which can compromise the structural safety of the turbines in a fire. The future of the big shovels, but … The German startup was news last year when installed 19.3 meters blades In Germany. Now seeks to overcome that milestone with blades of more than 50 meters in lengththe largest manufactured to date with laminated wood. However, in the field of wind energy, China continues to lead the race in large infrastructure. Recently, the Asian giant He has managed to install A Qihang wind turbine, with a 151 -meter tower and a 260 -meter diameter rotor. If mathematics does not fail, we would be talking that the length of a shovel is 130 meters, of course it is not laminated wood. And if I get more searching in the newspaper library, the discussion about the size of the wind turbines would give for an article itself. Just point out that at the moment none has surpassed the wind turbine to take advantage of the strength of the typhons with A 310 meter blade diameter. What we know so far is that laminated wooden blades could mark a before and after in wind energy, reducing costs and environmental impact. If the tests confirm its efficiency, this advance will open the way to more sustainable turbines.

It seemed that it was going to be one day flower, and well, in a way it has been: ‘The island of temptations’ has continued, but has not been able to find a viral hook from Montoya’s caliberthe contestant of the eighth edition of the reality that has starred several memes that have made him famous worldwide. His ridiculous jealousy attack, his possibly scripted race by the beach Bramano during the night and an exhausted Sandra Barneda shouting his name a few meters have made history in these first months of 2025. Astronomical audiences. Thanks to the meme that has generated not only messing in abundance, but also all kinds of variations, imitations and parodies, the audience of ‘the island of temptations’ He has shot. Last week, when the phenomenon exploded, it reached on Monday a 14.9% screen share, surpassing ‘El Hormiguero’ and not reaching ‘La Revuelta’ for a tenth. Later the audience shot, reaching 21.4%. On Wednesday (a unfolded program on Monday) it reached a decant 14.2%. And yesterday, with a new program, he swept 20.6%, now, beating his rivals in the coincidence strip. International fame. From the moment when Goldberg It was a trend in Spain Because in his morning debate program he spoke with his Montoya Meme contestants, we began to realize that he was reaching international draft. Community Managers of commercial brands They began to exploit it from around the world, Sporting events and shows around the world mentioned Montoya and its tortured Latin blood. Only one step was missing: making Montoya expressed in other languages. The AI ​​is in charge.

A German developer has bought a Nazi bunker for one million euros. Now he wants to turn it into a “fortress” for the rich

by

Germany is still grappling with the legacy of the Nazis. Throughout the country there is an extensive network of bunkers of the Second World War with the capacity to accommodate almost half a million people. Some of those left have been redesigned to serve citiesbut there are those who want to recover them for something similar to their original purpose: to be a fortress for the richest in the face of fear of a World War III. And they even have their own cryptocurrency: BunkerCoin. The project. It all starts when a real estate developer is occurred the idea: convert a World War II tunnel system into a bunker for rich people who fear a Third World War breaking out. those tunnels 13 kilometers long are near the town of Halberstadt, about 200 kilometers southwest of Berlin and were built by prisoners of the Buchenwald concentration camp. In 2019, businessman Peter Karl Jugl purchased these tunnels through his company Global Project Management for 1.3 million euros. Now you want to make profits. luxury bunker. Jugl’s idea is to create protected homes that also have all the facilities and comforts. “Similar to rooms on luxury yachts,” according to the project, with food to be obtained through agriculture and indoor mushroom cultivation. Among the amenities mentioned, we find a school, a workshop, a casino, hospital, workshop, gym and spa. So that the circadian cycle is not lost (although without sunlight it is somewhat complicated), the installation will simulate sunrises and sunsets in something extremely similar to what we can see in the nuclear shelters from the ‘Fallout’ saga. It will also be proof of a nuclear war. BunkerCoin. How is entry guaranteed? By purchasing a cryptocurrency, each one guaranteeing one cubic centimeter of space inside the bunker. It is estimated that a small room would cost around half a million dollars At the moment… The intention Historical memory. It is estimated that nearly 7,000 Buchenwald camp inmates worked in the tunnels and more than half died while digging. The purpose of the facility in its day was the manufacture of aviation equipment during the final phase of the war and, evidently, the plan for the luxury bunker has not pleased the descendants of those one bit. slaves who built it. Langenstein-Zwieberge is a memorial built in the vicinity of the prison camp that honors both victims and survivors and its director, Gero Fedtke, called the project “an inappropriate way of treating the historical heritage of the tunnel.” Disbelief. Curiously, all this has caught Jugl on a different footing. In a telephone interview granted told AFP that he has been letting visitors to the memorial access a section of the tunnel where historical traces from the Nazi era still remain, but he wanted to separate the tunnels from the prison camp located about two kilometers away. In addition, he commented that he is “building a facility to save human lives in an emergency and I have been treated unfairly, insulted and threatened.” An association of relatives of prisoners is not on that same page, pointing out that it is impossible to separate the tunnels from the camp, since the reason for the existence of that facility was to house the slave labor that would excavate the tunnels. Fedtke comments that, like the camp, the tunnels have historical relevance because in Buchenwald “hardly any historical traces of the Nazi era have been preserved and in the tunnel it is totally different.” still there. With all this commotion, Jugl has offered the state of Saxony-Anhalt the possibility of buying back the tunnels. It must be said that your company specializes in the purchase of “properties the bigger the better” with the aim of making them profitable and, now, it is offering the repurchase of the tunnel network for eight million euros. However, the state Ministry of Culture told AFP that they have not received any permit request for the construction of the bunker and that, “as it is a cultural monument, all structural or use changes require approval.” What they have received is the buyback proposal, something that has led some to think that Jugl’s plan was not to create any bunkers, but simply noise so that the state would give him more money than he originally paid for the tunnels and win. in the transaction. Whatever it is, it is a curious way to play with something as sensitive as the historical memory of the victims of Nazism.

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.
