6,400 panels north of the Arctic Circle

by

The world is immersed in the Renewable Energy Revolution. China is the Great powerin Europe we are seeing The sorpasso of renewables And even states like Texas have Uploaded to wind and photovoltaic car. However, there is a region in which bet on solar panels It looks like a contradiction: the Arctic. The reason? With a sun that for much of the year is up to the horizon, traditional panels sound like a waste. The trick is to stand up. And in the city of Troms the largest installation of bifacial solar panels in the world has just finished. Tromsøterminalen. North of the Arctic Circle is the city of Tromsø. Is at the upper limit of Norway And in a storage installation the world installation record of vertical photovoltaic units has just been exceeded, known as VPV. The roof of the trumsøtermine has hostel 1,600 VPV units that, in total, have 6,400 individual solar panels. It covers an area of ​​about 2,670 square meters and the installed capacity is 320 kWp. As they point in Interesting Engineeringthe CEO of Over Easy Solar (Norwegian company that He was in charge of the installation) comments that it is the vertical solar system located on a larger roof in the world. Too many ‘asterisks’, but the truth is that the orientation is impressive responds to a need. Vertical panels. Northern Norway has some Very capricious solar patterns. Focusing in Tromsø, from May to July there is a period known as the ‘midnight sun’. The sun remains visible 24 hours a day with different intensity, but there is also the opposite phenomenon: the ‘polar night’. From the end of November to mid -January, the star barely rises above the horizon. Depending on the area in Norway, there are between two and four months of continuous sunlight and another two to four at polar night. Traditional panels could not capture virtually anything when the sun affects too sharp angles, and that is where the VPV come out. If a traditional panel would reach 485 kWh yields in suitable conditions in this region, verticals can generate up to 55% more energy: about 750 kWh per year. Sun … and snow. In the winter months, that difference can become three or four times higher, but in addition to being more suitable to capture the sun when it is in the horizon line, these vertical solar panels take advantage of the Albano effect caused by the snow that accumulates between the ranks of panels and reflects the sunlight. That is: VPVs are capturing light from both the sun and what is reflected in the snow. It is estimated that this can increase energy production by more than 30% and, obviously, the advantage of vertical orientation is that snow does not accumulate on top of the panels, facilitating so much cleaning (The snow either Dust are enemies of photovoltaic plates) as ensuring a more continuous production. Tromsø is not the first system of this type and, in fact, is inspired by the success of the 1,200 VPV units installed a few years ago at the Oslo Ullevaal Stadium. In addition, it is an easy installation to perform (it was installed, according to The company, in four days for three people) and the CEO of Over Easy Solar trusts that that of tromsøterminate is an example for other cities of extreme latitudes. Although, really, they are not only useful in these conditions and there are already those who explore this solution on roads or in the Agrovoltaic facilities. Scalability. In fact, Over Easy is performing tests in which they measure the production of vertical panels not in extreme areas: but in one of the paradises of the photovoltaic: Spain. In the video below we see how a cluster of these panels produces on a roof in Elche: And that is on a roof is interesting because a problem that solar panels can have is their measured weight in kg/m². A traditional panel can weigh Between 15 and 25 kg/m² taking into account both cells and structure, hardware and other units. The one installed in the trumsøterminalen has a weight of 11 kg/m², which facilitates both the assembly work and the being able to fill roofs with panels.

16 Functions and tricks of the blue circle with the artificial intelligence chat

by

We bring you a list with The best functions and some tricks of Goal AIthe artificial intelligence that has been integrated into WhatsApp with A blue circle. It is something similar to having Chatgpt in WhatsAppbut in this case it is the AI ​​created directly by those responsible for the app. The idea of ​​integrating goal AI in the application is that you always have at hand the possibility of chatting with artificial intelligence and asking for anything without having to open any app. Now we will tell you some of the things you can ask to give you some ideas. And as we always say in Xataka Basics, we invite you that if you think we have left an important function tell us in the comments section. Thus, all Xataka readers can benefit from the knowledge of our xatakers. Get out messages like templates Have you been late for an appointment? Do you want to congratulate a birthday? Doesn’t it come in any ingenious to write? So goal ai can do it for you. You just have to ask for something like “write a message of ..” specifying what you want, and will do it for you with one or two examples. Here, what will generate goal AI is a template to which you then have to add names and others. You can also Specify the context of the message you want to write, or even the tone you want to use to make the result as well as possible. Check your messages before sending them But imagine that you want something more personal, such as writing your own long message to talk about an important topic. However, you are not sure that you have written it correctly. In that case, you can ask goal to Check the spelling and grammar From your message. Thus you can make sure you do not have any important error, especially in those cases in which the message is serious or professional and you want to make sure it causes a good impression. You can ask general questions As with any other artificial intelligence chat, a goal you will be able to ask that Information about whatever you want. You can ask you about things, sites, history, people, whatever you want, and the AI ​​will answer you with the information you have available. This information can be removed from the knowledge base with which AI has been entered and internet. In the event that the information is found on the network, Meta will add the link of the page that it has used as a source. Ask for specific information In addition to general information, you can also Ask for specific information On topics such as history, science, technology, art, literature or whatever you want. Again, goal AI will take your knowledge of your training or internet to answer you. Both this function and almost all can be found in other artificial intelligence chatbots, although the advantage of this is not to need to go out of WhatsApp to make the consultation. You can correct the information If you think it has failed in the answer, You can correct AI telling him that he has failed and what was the good answer. Then, the AI ​​will make a double checkeo of the information, and if it had effectively made a mistake will correct it and try that the changes apply for everyone. Ask for definitions of words and concepts You do not need a dictionarybecause if there is an expression, a concept or a word that you do not understand, you can ask goal to explain it to you. You can ask for any definition and will answer you in an understandable way. Translate texts into several languages Goal AI can also act as a translator.

For 15 years a strange circle under an island in Japan was an enigma. The author’s identity was a surprise

by

If we go to the dictionary to be exact with the term, the verb “courtej” accompanies the following definition: try to get the love or favors of someone flattering him and looking for his company. Therefore, the finding that took place several decades ago was so surprising. Normally, when we talk about courting WE THINK HUMAN KEY. However, in the animal kingdom they exceed everything seen in our species when it comes to claim the attention of the other. The enigma of the circles. In 1995, a group of divers who were exploring the waters near Amami ōshima, Japan, Japan, They discovered strange circular formations In the seabed. It was surprising, since those structures were symmetric, with radial spikes and valleys, and with such a prominent geometric perfection that it aroused all kinds of speculation about their origin: were they facing a human creation, or was it due to some kind of unknown natural phenomenon , or maybe an unusual organism? The years passed, and it was not until 2011 that A team of scientists managed to solve the mystery. Not just that. They managed to “catch” the suspect repeating the lavish scene. To the surprise of the researchers, the protagonist was A tiny torquigener albomaculosusa small kind of balloon fish that, with a size of just 12 centimeters, seemed to be able to sculpt structures 16 times larger than their own body with a very specific purpose: seduce a couple for reproduction. The art of courtship under the sea. The year of the finding, the scientists recorded the process of creating these circles in the seabed, observing up to 10 reproductive events in two study areas. Each structure took between seven and nine days to complete and required extreme precision. The male balloon fish used its pectoral, anal and flows fins to dig and model the sand in a perfect radial pattern, alternating between rapid and strategic pauses movements To give texture to the formations. In addition, he decorated the peaks of his work with decorative elements such as shells and coral fragments, while the center of the circle was completely clear as we see in the images. Only when these final details were ready, The females began to approach to evaluate the design of the “artist”. The mating ritual. At this point, when a female was interested in the structure, The male stirred the fine sand of the center to attract his attention. If she decided to enter the circle, the male withdrew momentarily before swimming quickly towards her in a repetitive courtship dance. If the female was impressed, she put her eggs in the center of the circlemaking it a temporary nest. If that was already fascinating, shortly after it was revealed that the impressive structures were never reused, they were of only one use. After reproduction, males leave their creation and begin a new one from scratch, since the process of sculpting the circle consumes most of the finest and most adequate sand for reproduction. This apotheosic nest construction ritual, documented years later In the Big Pacific series of BBC Earth/PBS and narrated by Sir David AttenboroughHe has amazed biologists and spectators since then. Ephemeral art. No doubt, the complex work of the balloon fish is One of the most fascinating exhibitions of the animal kingdomcomparable to the elaborate dances of mating of birds or the constructions of some mammals. However, what makes these structures unique is that these are true underwater works of art, carefully designed and molded with geometric precision. In addition, its discovery also offered a new perspective on the evolution of courtship in vertebrates. Although humans tend to think about art and architecture as exclusively ours capacities, these seabl , all that, and surely something else, in the extraordinary work of a tiny creature.
