France is installing turbines under the sea to exploit the renewable energy source that never ceases: the tides

by

In the heart of the sea, where the powerful tidal currents move to the rhythm of lunar gravity, an energy revolution is being created that promises to transform the future of Europe. France has a continuous energy with a large -scale installation. The project. French company Normandie Hydroliennes has created The NH1 initiative to generate energy from sea currents. The installation will consist of four seniomotor submarine wind turbines that will be located in the Raz Blanchard, a sea step known for its currents. The great support. EU 2023 Innovation Fund He has subsidized to the project with 31.3 million euros. In this way, Europe expects to integrate tidal energy into the energy mix in France and Europe, adding a constant and predictable source to avoid Intermittent energy problems. The largest in Europe. Thus it will be thanks to the AR3000 turbines, which are considered The most powerful in the world in the mareomotor energy sector. Each turbine will have a 3MW power and a 24 -meter rotor diameter and, its advanced control system will constantly adjust the speed and angle of the blades to optimize the production of electricity. It should be added that the marine structure of these turbines allows them to be installed in just 20 minutes. Stable energy. An interesting small fact is that this type of renewable energy offers a stable and continuous supply, thanks to Natural forces as the lunar gravity that generates the tides and moves the oceans continuously. Energy sending. The energy generated by the turbines will be transported to the ground through a single export cable, which facilitates the connection of multiple turbines to transmit the electricity generated efficiently. This type of very demanded cables in Europe It has made effective The network connection between England and Denmark, among other projects. However, too It has been target of objectives In geopolitical conflicts. The occasional setback. Like any type of large -scale system, problems may appear. The company has indicated that the design of the project minimizes the environmental impact and reduces costs, but problems may arise due to the extreme marine conditions of the sea pass. As for the marine impact, problems may arise of local fauna and flora. Forecasts. From the French company have indicated which will provide 34 GWh per year to the France electricity network from 2028. In addition, they have estimated that this energy source has a potential of up to 100GW by 2050, supplying the electrical needs of 94 million homes throughout the continent.

8,000 years ago a group of farmers crossed the Aegean Sea. Its trail can still be seen in the DNA in Media Europe

by

A little before 7,000 before Christ, the western hunters-gatherers and the center of the Anatolia They started cultivating. It seems likely and unimportant. But that little change ended up causing a deep social, economic and demographic reorganization of the entire European continent. And it is not an exaggeration. It was so strong that even today we can see her on the maps. PH2TER What are we talking about? Between 6,000 and 4,000 before Christ, those Neolithic Farmers of Anatolia They began to move beyond the Aegean And, progressively, they took agriculture to Europe and North Africa. They thus became the ancestral genetic component of this whole area of ​​the world. Subsequently, the arrival of the shepherds of the western steppe (the known as Yamnaya culture) He finished configuring the basic genetics of the historical peoples of Europe, but the strength of the legacy of the anatolian farmers remained very strong. Above all, in the south of the continent. How can this know? Taking into account that the databases are even more incomplete than we would like and, therefore, there is always enough speculative content, a map can be built by comparing historical and contemporary samples. On the map, you can see a spectrum in which blue represents populations with greater “genetic distance“With the neolithic anatolic farmers and the red the slightest distance. And, to tell the truth, it has enough surprises. Detlef Gronenborn, Barbara Horejs, Börner, Obe Who is who (genetically speaking)? As usually explained, in the European countries of the Mediterranean there is a greater genetic closeness with the first European farmers. Specifically, Greece and Italy are the sites with the greatest closeness. Sardinia, of which we already knew that They were a very unique genetic populationit seems that the palm is taken. As a curiosity, it seems that current anatolia is not so great. Paleogenetics for beginners. All this is still a curiosity of an amateur forum (one that presumably has serious reliability problems as we approach detail). However, it is a good example of the enormous depth that genetic studies give us to understand the intrahistory of humanity. As we said Half decade ago“Paleogenetic techniques are like Galileo’s telescope: they let us see where we could not until now, but we need to accumulate evidence, works and studies to know what is true and what is a mirage.” As happened with carbon-14 techniques (it took almost 40 years to be reliable to one hundred percent), we are about to see how the past changes.

How US ships repelled the red sea drones without shooting a single shot

by

In recent months, several news in those points of the planet where there are tensions or directly some kind of armed conflict, they gave us the first clues. The war that was fought until very recently has given way to a very different one where the human loses importance in the first line of the contest. That’s why United Kingdom has sent the P8 Poseidon to protect your submarine cables, or In Ukraine an optical fiber is worth more than some ammunition. Now, a document has revealed to what extent the war is different. Non -kinetic weapons. I told Business Insider a few hours ago through secret documents that have obtained from the intelligence of the United States. Apparently, during the American mission to counteract the attacks of the Hutis rebels in the Red Sea, The destroyers of the United States Navy such as the USS Mason and the USS Serly, managed to repel all drone attacks without firing Missiles or conventional ammunition. We talk about A period that covers between November 2023 and March 2024space in which these ships used non -kinetic capabilities, technology that includes advanced electronic warfare systems to deactivate enemy drones through electromagnetic interference and cyber attacks, instead of traditional defense methods. The electronic war revolution. The documents obtained by the medium reveal that these ships used advanced technologies such as the AN/SLQ-32 (“slick-32”) and the so -called Ship’s Signal Exploitation Equipment (SSEE)both designed to detect, interfere and neutralize the signs of enemy drones and missiles. These systems allow interrupt communications and guidance mechanisms of drones, leaving them inoperative without the need to physically destroy them. This technique, although it is part of the naval doctrine for years, had never been used with the intensity that is currently made against drone swarms in a real conflict. In fact, something similar in Ukraine is happening, The “mother of all battles between drones”. Strategic benefits in non -kinetic weapons. The use of electronic war for naval defense represents a crucial advance, in this specific case for the United States Navy, in front of attacks such as those perpetrated by the hutis, who They have launched about 500 drones against ships in the Red Sea and the Gulf of Adén since October 2023. Here The key advantages of these systems are several. From the savings of ammunition, since, instead of spending expensive missiles in each enemy drone, non -kinetic weapons offer a cheaper and more efficient alternative, until sustainability in combat, since by avoiding the exhaustion of the arsenal, ships can stay in the theater of operations without the need for frequent refueling. Plus: greater tactical adaptabilitysince the electronic war allows to counteract threats in real time, without revealing the location of the ship with shots or generating traces of heat. A change in the naval strategy. If you want also, the success of these systems in the Red Sea conflict marks a turning point in the Maritime War doctrine. In this regard, experts such as Bryan Clark, ex -official of the Navy and defense analyst at the Hudson Institute, highlight that this is The first time that the United States faces a massive use of aerial drones in anti -ribous attackswhich has forced the Navy to develop more sophisticated tactics. The experience obtained in these clashes not only strengthens the defensive capacity of US ships, but also provides key lessons for future conflicts, in which electronic war and non -kinetic weapons could play a predominant role. Exactly the same that happens in Ukraine where The battle has moved to another completely different level to other conflicts. A fact before finishing to understand the importance of this new paradigm shift: last year and in just two days, 1,600 aircraft in Europe had problems with GPS. He guilty: Electronic War.

This is how climate change is making Valencia a match in the middle of a sea in flames

by

January has the days counted and the Valencian thermometers seem to be in the wrong month. In more than a century and a half of data, a temperature had never been recorded above 26.6 degrees In the city of Turia. Well, yesterday Aemet devices They reached 27.1. AND It is not an isolated fact: We can travel the entire community jumping from weather station to weather station and a surprising amount of them would be for 25 degrees. In Chelva, a couple of days ago, The 30 were touched. But is this weird? The truth is that. Normal, according to the historical series, is that temperatures They should range between 10 degrees during the nights and 16 during the day. Overcoming the 25 is nothing that can be classified as “normal.” But it cannot be said that it is just a meteorological curiosity, it is a much greater problem than only now we begin to understand. What is happening in that Mediterranean area? The seasonal forecasts of Aemet They already drew A warmer winter than normal. I should not miss anyone: 73% of the 2024 days had an average temperature higher than the historical average of reference (and, As they point from the agencythat “the average is already a warm period”). Cold peaks, on the other hand, are increasingly rare. It is almost unimaginable that the Valencian garden suffer a cold wave Like 1956 or January 1891. In the latter, Castellón spent days to -10 degrees and the people of Grau could see one “immense ice belt on the banks of the Mediterranean“ That, today, is science fiction. The world, little by little, has been heating. So it has to do with climate change? In general, attributing weather events to climate change is complicated. Because, deep down, we always talk about probabilities and, although probabilities are never zero, As Aemet explains“In a stable climate it is very likely that these warm days would not have produced.” That’s where climate change enters. And, “due to the form that this data is adjusted to a normal distribution, the increase of 1.5 ° C of the average temperature gives rise to the fact that values ​​before rare or impossible, Now they are probable“ What consequences does all this have? Halfway between the causes and the consequences are The very high temperatures that the sea has. Much higher temperatures than we could imagine just a decade ago and than They have experts intrigued. To all purposes, the Mediterranean is becoming a gigantic battery of energy that “Try the strength of atmospheric phenomena“. It is inevitable to think about THE GREAT DANA OF 2024but The impact Of these new scenarios it goes much further. Does this mean that complicated moments come? Means, above all, that socioclimatic balance in which we were installed it is changing very fast and we do not know for sure where it is directed. That complicates the forecast and hinders management, but emphasizes the need to be prepared. A task in which, as the Dana showed us, everything remains to be done.

North Korea tests cruise missiles from the sea

by

North Korea tried strategic cruise missiles launched from the seaannounced the state press agency KCNA, adding that the missiles reached their objective with “precision.” The North Korean president Kim Jong-un, who according to the agency attended the evidence, said that “the means of deterrence of the Armed Forces of the Democratic People’s Republic of Korea are more deeply perfected.” The missiles reached their goal after traveling 1,500 km trajectories In the form of eight and elliptical, Kcna said, without specifying where the tests were carried out. He said that “there was no negative impact for the safety of neighboring countries.” This is the first trial of North Korean weapons since Donald Trump’s return to the White House. Shortly before his presidential investiture on Monday in Washington, North Korea triggered several short -range ballistic missiles to the sea. Trump, who held several meetings with Kim during his first government, said in an interview released on Thursday that he would contact the North Korean leader, which he called an “intelligent type.” Continue reading:• Historical Defense Treaty between North Korea and Russia between officially in force• North Korea enlists more troops and “suicide drones” in support of Russia, according to Seoul• North Korea and Russia ratify Treaty of Defense and Immediate Military Aid (Tagstotranslate) North Korea
