the top, the young man and the great rival of the folding iPhone

by

Samsung has introduced its new Galaxy Z series: Fold8, Fold8 Ultra and Flip8. It is not a hierarchy from high-end to low-end, but three different ways of understanding a foldable, each one aimed at a specific type of user. Fold8 For those who want a foldable designed above all for consuming content: its screen is adapted to video, reading and networks, with a lighter body than the rest of the range. Fold8 Ultra for those who prioritize productivity and a top camera. It is the thinnest foldable launched by Samsung and its 8-inch screen allows you to work on several applications at the same time. Flip8 for those who prioritize being able to carry their cell phone in their pocket, no matter how small it is, and the lifestyle. Also for those who prefer not to open their phone if it is not necessary: ​​its external screen has been redesigned to be able to do more with it and not have to unfold it.

And therein lies the key to who each one is for. Samsung Galaxy Z Fold8. Image: Samsung. The Fold8 It has a 4:3 interior screen, more square than elongated. Samsung explains that this format imitates the proportions of a magazine or a book: it is comfortable for reading, watching vertical or horizontal video and browsing, but it is not designed to have two or three apps open at the same time. On the outside, its 10:16 screen is the narrowest in the range, ideal for using it folded like a normal mobile phone. At 201 grams it is the lightest Fold, and it has a 50 MP dual camera, enough for everyday use, although it is not the best. It is, in short, a foldable built to consume content comfortably, not to work on it. And it is, coincidentally, the same form factor that has been leaking for months on Apple’s first foldablescheduled for a month and a half. Samsung doesn’t say it like that, but it has come first with a design that so far no one else has released in that exact format. At least in Spain. Because Oppo had its Find Nbut not in our market. Samsung Galaxy Z Fold8 Ultra. Image: Samsung. The Fold8 Ultra reverses that logic. Its interior screen grows to 8 inches, large enough to divide it into several windows and work with two or three applications at the same time, something that the normal Fold8 does not offer with the same comfort due to its more elongated shape. In exchange, it weighs more, 215 grams, and includes a 5,000 mAh battery and an expanded graphite cooling system to withstand long workloads: editing, multitasking, content creation… Its main camera jumps to 200 MP with HDR, designed for those who need the best possible results. It is the same screen size as a Fold8, but with the hardware aimed at producing instead of consuming. Samsung Galaxy Z Flip8. Image: Samsung. The Flip8 plays in another league different: It does not compete in interior screen size with either of the two, because its beauty lies in folding up to fit in a pocket. At 6.1 mm thick, it is the thinnest Flip that Samsung has ever launched, and its differentiator is not the main screen but the exterior FlexWindow, now converted into an interface with its own AI: it allows you to respond, consult information or launch actions without opening the mobile. It is the foldable designed for those who use their cell phone in short bursts throughout the day, not in long sessions. Yes, but. The Fold8 is not the flagship. That role is maintained by the Ultra: more battery, better camera, and larger screen. Anyone looking for “the most powerful folding Samsung” should not look at the passport format model, but at the Ultra. Samsung takes a risk here that it does not usually take: launching three folding devices at the same time means that they compete with each other for the same buyer, not only with the rest of the market. And now what. The three models are already in the reservation period in some markets. Samsung has not confirmed prices yet. Each purchase will include six free months of Google AI Prowith 5 TB of storage.

Samsung has not only brought us foldables. The Korean company has taken advantage of Unpacked to renew its range of smart watches which, as tradition dictates, consists of two devices: the Ultra model and the standard model which, again, as tradition dictates, this year skips the Classic version (and its fantastic rotating bezel). We have, therefore, two new smartwatches that seek to win the gold of “best watch with Wear OS.” The most striking change is found in the Ultra, which greatly increases the level of its battery and brightness, but otherwise both watches share many of the functions and specifications.

We earn commission from these links The peculiarities of the Watch Ultra2 Samsung Galaxy Watch Ultra2 | Image: Xataka He Watch Ultra2 It is the watch focused on the most athletic and, why not say it, those looking for a powerful watch that offers good autonomy. It is only available in a single 47 millimeter version, so yes, it is a big watch not suitable for small wrists. The frame is made of aluminum and is somewhat thinner than the previous model, specifically 12%. As a sports/adventure watch that it is, it has all kinds of certifications and resistances to withstand the elements of, for example, water. Samsung boasts of offering resistance IP69K10 ATM (equivalent to 100 meters depth) and EN 13319. It is obvious that he feels good in the water and, in fact, it has a mode dedicated to diving that measures immersion time, water temperature, speed of ascent and descent, etc., developed together with Mares. Samsung Galaxy Watch Ultra2 | Image: Xataka Coming out of the sea, the device has a feature called “Mountain Run” that offers information on altitude and terrain impact, and offers real-time hydration recommendations through Nutrition Alert. Basically the clock estimates sweat loss in relation to body weight and tells us when we need to drink water. Last but not least, it has a screen with 5,000 nits of brightness (a completely absurd figure that, it must be said, we will take advantage of on very rare occasions) and 800 mAh battery. This change is notable compared to the previous generation, which had 590 mAh, and the reason, although Samsung does not mention it explicitly, seems obvious: silicon carbon batteryfinally. A review of Watch9 Samsung Galaxy Watch9 | Image: Xataka He Galaxy Watch9 It is a watch more focused on everyday life. Although, as we will see soon, it offers the same sensors as its Ultra brother, this watch has a more casual, more lifestyle character. It is, without a doubt, more focused on keeping track of our lifestyle habits, sleep and exercise, as well as serving as a productivity assistant through notifications, calls and apps. This model can be obtained in two versions: 40 and 44 millimeters. One is smaller, one is bigger. That obviously has a noticeable impact on the watch’s battery. While both do exactly the same thing, the 44-millimeter one will offer greater autonomy. Both have a frame made of aluminum and that “padded” design that the Galaxy Watch8. Samsung Galaxy Watch9 | Image: Xataka The screen does not reach the 5,000 nits of the Ultra2, but it does amount to 3,000 nitsa much more reasonable figure that, in any case, will only be activated in fairly extreme lighting conditions. As far as stamina goes, it’s pretty tough, but not as tough as its older brother. It does not have EN 13319 certification, nor IP69K nor does it reach 10 ATM, so, although it can withstand water, it is not designed for diving.

If you’ve ever tried to clean under a sofa with a wet-dry vacuum cleaner, you’ll know how frustrating it can be: most of the deposits stuck to the handle prevent the device from completely lying down. Roborock seems to have taken note of this problem in its new catalog of upright vacuum cleanersbringing to Spain two models that directly attack the usual weak points of this category: maneuverability and disinfection. The new ones Roborock F25 Steam and Roborock F25 GT Gen 2 They are now officially available in Spain from 199 euros (per launch campaign), thus offering a very interesting alternative to traditional high-end brands. roborock F25 GT Gen 2 Wet and Dry Vacuum Cleaner The price could vary.

Its great asset is technology VaporFlowcapable of projecting steam at 180°C directly onto the floor to soften stubborn grease and dirt in a single pass. Beyond steam, it solves two of the main problems of this type of vacuum cleaners: Gets under the furniture: Thanks to the FlatReach 2.0 system, the vacuum cleaner reclines until it is completely flat (only 12.5 cm thick), allowing you to clean under beds or sofas without losing suction. Self-maintenance: At its base, it not only washes the roller with steam, but dries it with hot air at 95 °C to avoid bad odors due to retained moisture. With a autonomy of up to 80 minutes in Eco mode and dirt sensor in real time (DirTect), is a cleaning beast that costs the usual 589 euros, although it comes with an introductory offer for 459 euros. roborock F25 Steam Vacuum Cleaner and Steam Scrubber The price could vary.

Unlike the previous generation, the brand has redesigned the weight distribution by placing the water tank in the lower area. This makes it much more agile to push and turn between the table legs. It maintains the ability to lie down at 180º and stands out for its respectable 20,000 Pa of suction and a dual scraper system (JawScrapers) designed so that dog or cat hair does not get tangled in the roller.

The Korean company has managed to reduce its thickness and weight to 6.1 mm and 180 grams (6.5 mm and 188 grams in the Z Flip7) while retaining the 6.9-inch screen diagonal. The rest of the specifications are similar to last year’s model, except for the peak brightness, which goes from 2,600 to 3,000 nits. There are no significant changes to the design. Samsung has once again opted for a rear divided into two parts, the upper part being a generous 4.1-inch screen from which to interact with the AI, make calls, view notifications, etc. We have another novelty in the hinge. Samsung has mounted a new technology called Flex Titanium which, roughly speaking, combines a titanium film with a titanium plate in the area of ​​the wrinkle to, on paper, reduce the impact and reduces the visibility of the crease. The theory is that should be noticed and seen less. We will discover the reality when we can analyze it. An engine signed, again, by the house Samsung Galaxy Z Flip8 | Image: Samsung While the Fold brothers incorporate the Snapdragon 8 Gen 5 Elite for Galaxy, the Z Flip8 mounts the Exynos 2600. It is the same strategy that the firm followed last year with the Flip7, which mounted the Exynos 2500. It is a two nanometer chipten cores and a thermal management system that, at least in theory, should stand up to the thermal throttling we experienced in the Flip7. Next to this chip we find 12 gigabytes of RAM and 256 or 512 GB of internal storage, as well as 4,300 mAh battery with 25W fast charging. Same setup as last year, in a nutshell. Samsung still does not dare to make the leap to silicon-carbon and, in terms of performance, the experience should be very similar. Samsung Galaxy Z Flip8 | Image: Samsung A change is found in the operating system, which is now Android 17 with One UI 9. Samsung, by the way, promises seven years of updates. Numbers aside, the Z Flip8 has seen the FlexWindow experience renewed, that is, the capabilities of the external screen, the one we use when it is folded. According to Samsung, FlexWindow “brings apps, information and actions directly to the outer screen,” so in theory it should be possible to use apps like WhatsApp or email from that screen. Now Brief is also displayed on that screen and, by clicking on the side button, it is possible to automate actions through Gemini Intelligence. Two cameras with the focus on creation Samsung Galaxy Z Flip8 | Image: Samsung Few, if any, changes in hardware compared to the last generation. The Flip8 mounts a set of two sensors on the rear (50 MP wide angle with OIS and 12 MP wide angle) and a front sensor on the 10 MP internal screen. We do not have telephoto, as is common in this range. We will use the 10 megapixel camera for video calls and little else, in case this format allows something, it is being able to use the main cameras for selfies (group ones included). Flex Mode allows you to place the folded screen in any position to use it as a tripod, for example; And as a novelty, now the camera is capable of blocking the horizon so that the videos come out well framed even when moving.

After endless leaks and rumors, Samsung has made a new folding format official. Not “new” as such, but different. Because he Samsung Galaxy Z Fold8 It is still a Fold, but now it is much, much more square and, therefore, more panoramic when we open its screen. It is a foldable made, according to Samsung, to adapt to how we see content. This format is usually known as “passport type” and it is something that we have already seen, to a certain extent, in the OPPO Find N (Apple is also expected to adopt it at the end of the year in its much leaked iPhone Fold). The Korean firm thus puts on the table a triad of foldingeach one focused on a different audience and the Fold8 being the most generalist. With the introductions made, let’s get to know them better. Before continuing, we remind you that the members of Xataka Xtra can access discounts, benefits and exclusive opportunities in the Samsung online storein addition to exclusive raffles, a private Discord server and a growing catalog of discounts and advantages on digital services.

Samsung Galaxy Z Fold 8 technical sheet SAMSUNG GALAXY Z FOLD8 Dimensions and weight Folded: 81.9 x 123.9 x 9.7 mm Unfolded: 161.4 x 123.9 x 4.5 mm 201 grams folding screen 7.6-inch Dynamic AMOLED 2X QXGA+ resolution (2,448 x 1,848 pixels) 403 pixels per inch Refresh rate: 1-120Hz Vision Booster main screen 5.5-inch Dynamic AMOLED 2X QXGA+ resolution (1,248 x 1,972 pixels) 428 pixels per inch Refresh rate: 1-120Hz Vision Booster Up to 3,000 nits Low reflectance screen processor Snapdragon 8 Elite Gen 5 for Galaxy Ram memory and storage 12/256GB 12/512GB 16GB/1TB front camera Main screen: 10 MP, f/2.2, FOV 85º Folding screen: 10 MP, f/2.2, FOV 100º main camera 50 MP wide angle, dual pixel AF, OIS, f/1.8, FOV 85º 50 MP wide angle, dual pixel AF, f/1.9, FOV 120º battery Dual 4,800 mAh (typical) 45W fast charging 20W wireless charging PowerShare Reverse Wireless Charging connectivity 5G NSA/SA LTE Wi-Fi 7 Bluetooth 6.0 NFC GPS operating system Android 17 One UI 9 others IP48 resistance Galaxy AI Knox Now Brief Now Nudge price From 1,999 euros The new passport format Samsung Galaxy Z Fold8 | Image: Samsung To date, Samsung’s Fold-type folding devices (and almost all brands, really) have tried to be a conventional mobile phone that multiplies by two. The external screen is like that of a regular mobile phone and, when we open it, its size doubles in a screen that borders on the 1:1 format (almost square). The problem is that this format, which is maintained, by the way, in the Fold8 Ultra, is very good for multitasking and productivity, but it involves certain sacrifices in the consumption of multimedia content. The reason? A video on YouTube is usually in 16-18:9, which, on an almost 1:1 screen, means having two huge black bands above and below the content. The passport format partially solves this problem: it sacrifices diagonal on the main screen in exchange for offering a more rectangular folding screen, ideal for watching a video, a movie or playing games in widescreen format. In the case of Samsung, the main screen (the one we use when it is folded) has a 10:16 format. Samsung Galaxy Z Fold8 | Image: Samsung Samsung Galaxy Z Fold8 Ultra | Image: Samsung The folding screen, for its part, has a 4:3 format. Without being completely panoramic, the upper and lower black bands will be a lot, but much smaller. If we put it vertically, we have a size similar to that of a small book, which makes it particularly comfortable for reading or browsing. When it comes to the hinge, Samsung boasts a new technology called Flex Titanium (available in all three folding versions). According to the company, this new hinge combines a titanium alloy film with an “improved” titanium plate that, on paper, helps reinforce the screen support, absorb pressure and reduce crease visibility. This has been one of the most controversial points of foldables historically, the fold and its wrinkle. Speaking of specifications Samsung Galaxy Z Fold8 | Image: Samsung If we talk about inches, the main screen has a 5.5 inch diagonalwhile the folding one amounts to 7.6 inches. In both cases we find a QXGA+ resolution and a variable refresh rate of 1-120 Hz. They are, therefore, fast screens with a more than acceptable resolution. As far as brightness is concerned, 3,000 peak nits, more than enough to use it in full sun and play HDR. One of the things that caught the most attention Galaxy S26 Ultra was the anti-glare and anti-glare screen. For physical and space reasons, Samsung cannot implement this technology in the folding ones (this specific model is 4.5 mm thick when unfolded), but it does claim to have introduced a low-reflective finish that, in theory, should reduce glare when the sun shines in front of it. Maximum power Samsung Galaxy Z Fold 8 | Image: Samsung Samsung has not skimped on power in its new foldable. In fact, in a somewhat complicated context for RAM and storagethe Korean firm has put all its efforts into action. The Galaxy Z Fold 8 has 12 GB of RAM in its versions with 256 or 512 GB of internal storage, and 16 GB in the most powerful version, which is the one with 1 TB capacity. It won’t be for storage, of course. The heart of the terminal is a Snapdragon 8 Elite Gen 5 for Galaxy, or what is the same, a Snapdragon 8 Elite Gen 5 with a lightweight overclock which, on paper, provides extra performance. It will also be responsible for moving some AI tools, namely Now Brief (contextual information), Now Nudge (an assistant for taking actions) and the editing suite. However, Samsung’s approach is hybrid: local+cloud. The battery goes up to 4,800 mAh, which represents an increase of 400 mAh compared … Read more

Many foods and cosmetics have additives that we want to avoid at all costs.

by

Every time we put a packaged potato omelet, hummus or moisturizing cream in the shopping cart, we incorporate dozens of substances into our body that often go unnoticed despite appearing on the label. The preservativesdyes, emulsifiers or sun filters are part of the usual composition of thousands of products that we buy in supermarkets. His presence responds to a legitimate industrial logic: it is necessary to extend the shelf life of a food or stabilize the texture of a cosmetic. The problem is that the regulations that regulate these additives almost always advance behind scientific knowledge. An additive can take decades to be approved and in widespread use before scientific studies force authorities to reopen its file. The European Food Safety Authority (EFSA) periodically reevaluates these compounds, but its way of working requires accumulating solid evidence and sustains years of continuous exposure before any regulatory change. This disconnection does not at all mean that everything permitted is automatically dangerous. In fact, the vast majority of authorized additives are supported by decades of toxicological studies. Even so, it is in consumers’ interest to know which substances have generated the most scientific controversy, in which products they appear most frequently, and which institutions have focused on them. Preservatives that are already under discussion Sodium benzoate (E211) is one of the most commonly used preservatives in packaged potato chips, pickles, sauces and soft drinks. The EFSA has reviewed your security on several occasions, the last in 2016, and has concluded that within the authorized levels it does not raise concerns about genotoxicity (the ability of a substance to damage the genetic material of a cell). It has warned, however, that certain population groups can easily exceed the acceptable daily intake. A quick note before we move forward: part of the controversy about this additive comes from research such as those of Professor Peter Piperfrom the University of Sheffield (United Kingdom), who has documented damage to mitochondrial DNA of cells exposed to sodium benzoate in in vitro assays. EFSA opts for regulatory prudence, while certain academic groups insist on stricter scrutiny Potassium sorbate (E202) follows a similar logic. It frequently appears in hummus, cheeses, yogurts or wines, and acts as an antifungal. The EFSA has reevaluated it in 2015 and again in 2019setting an acceptable daily intake together with sorbic acid of 3 mg per kilo of body weight per day. A study published in In Vitro Toxicology evaluated its genotoxic potential in human lymphocytes cultured in the laboratory, without finding relevant effects at the concentrations tested, which reinforces the official position of the agency. Another relevant note: both preservatives share the same pattern. No reference institution has classified them as carcinogenic, but there is no unanimity regarding their complete long-term safety. The EFSA opts for the regulatory prudencewhile certain academic groups insist on stricter scrutiny, especially in sensitive populations, such as children or people with an aspirin allergy. However, we are interested in putting these figures in context: the real exposure of those who eat packaged potato omelettes several times a week is well below the thresholds at which adverse effects have been observed in the most alarmist studies. The additives most highlighted by science Beyond preservatives, there are other additives that have received much stronger regulatory attention. The clearest case is that of titanium dioxide (E171), a white dye used for decades in candy, chewing gum and some cosmetics. The EFSA concluded in 2021 that its genotoxicity cannot be ruled out, especially due to its ability to accumulate in the body, which has led to the European Union to ban its use as a food additive from 2022. Even so, it is still allowed in cosmetics, such as sunscreens. The antioxidants BHA (butylated hydroxyanisole, E320) and BHT (butylated hydroxytoluene, E321), present in snacks, cereals and some cosmetics, illustrate well the nuances of this type of evaluations. The International Agency for Research on Cancer (IARC) has classified BHA in group 2B as possible carcinogen for humans. BHT, on the other hand, remains in group 3, not classifiable due to insufficient evidence. The International Agency for Research on Cancer has classified BHA in group 2B as a possible human carcinogen. The European Commission has also placed BHA as a priority substance for endocrine disruption, while BHT only arouses similar suspicions in the scientific literature, without an equivalent institutional classification. Long-chain parabens in cosmetics follow a similar path: several of them are banned in the European Union since 2014 by decision of its scientific consumer safety committee. Sodium nitrite (E250), common in sausages and processed meats, closes the list with the best documented case: the IARC classified processed meat as a group 1 carcinogen in 2015, especially due to the formation of nitrosamines when cooked at high temperature. In the following table we summarize these six cases and identify the institution that has indicated the risk of each of them and the effects described in the scientific literature: Additive Where do we find it? Institution that has indicated the risk Described effects E211 (sodium benzoate) Packaged potato omelettes, pickles, sauces, soft drinks EFSA (2016 revision); University of Sheffield Overcoming the IDA in sensitive groups; damage to mitochondrial DNA in in vitro studies E202 (potassium sorbate) Hummus, cheeses, yogurts, wines EFSA (2015 and 2019 revisions) Possible cellular inflammation in animal models E171 (titanium dioxide) Candies, gum, sunscreen EFSA (2021 opinion) Genotoxicity not ruled out; banned as a food additive in the EU from 2022 E320 (BHA) / E321 (BHT) Snacks, cereals, some cosmetics IARC (group 2B for the BHA); European Commission (priority endocrine disruptor for BHA) BHA, possible carcinogen and hormone disruptor; BHT, similar suspicions without equivalent classification Long chain parabens Creams, shampoos, cosmetics Scientific Committee on Consumer Safety (EU) Hormonal disruption; several banned in cosmetics since 2014 E250 (sodium nitrite) Sausages, processed meats IARC (group 1 for processed meat, 2015) Formation of carcinogenic nitrosamines when cooked at high temperatures Image | Kenneth Surillo More information | EFSA | European Union | IARC In Xataka … Read more

“I don’t understand Stallone, I have the impression that he only does it for money”

by

That phrase from Clint Eastwood is not current, but belongs to 2003, to a profile that Lillian Ross wrote about Eastwood for ‘The New Yorker’. Curiously, after that Stallone returned to Rocky, but he did so with a film that was a huge critical and public success. And Eastwood did not return to any of his previous films. That is, a quarter of a century later, the quote is nuanced but it essentially means the same thing. What is it coming for? That “I don’t understand Sylvester Stallone. I have the impression that he only does it for money” was said within Eastwood’s broader reflection on his own career: he was talking about Harry Callahan, about the risk of stagnating artistically, about the need to grow instead of going backwards. At that time, it was not known whether ‘Rocky Balboa’ would end up being a worthy film or a nostalgic wreck. In 2003, filming hadn’t even started. It was cool. Three years later, Stallone wrote, directed and starred in that sixth installment. The critical reaction far exceeded that of its two predecessors: Rotten Tomatoes Today it scores 78% out of 180 reviews, well above the reception that ‘Rocky V’ had in 1990. In commercial terms, ‘Rocky Balboa’ grossed 155.9 million dollars with a budget of 24 million. The installment that recovered Rocky was a very worthy tribute to a classic character. Everyone sins. Eastwood was also not free from the impulse to resurrect characters. He played Harry Callahan five times between 1971 and 1988, until ‘The Blacklist’, the last installment of the saga. When a sixth Callahan was finally ruled out, Warner Bros. did not close the door: in 2004 it considered relaunching the franchise with Dwayne Johnson as a thirty-something detective. The plan died due to Johnson’s own box office failures. Without consequences (relatively). However, Eastwood has remained true to his words: in 2003 he had already abandoned Callahan’s films many years ago and was fully immersed in a career as a complete auteur accepted by Hollywood. Words are always relative, yes, because at the end of the day… what are films like ‘Unforgiven’ if not late sequels to his successes as a protagonist for directors like Leone, where the director wonders what happens when the icons reach an advanced age and all the treasures obtained by clean shooting have come to nothing? What remains The really valuable thing about this statement, which we must remember that the current nonagenarian Eastwood has not uttered, is that it is infinitely nuanced: Rocky returned to one of his classic franchises (and would do so again with ‘John Rambo’, another critical – to a lesser extent, yes – and public success), but it was a more than worthy return. And Eastwood would stay true to his words, but four Dirty Harry sequels are there to remind him that there is no one with a completely irreproachable career.

The Korean company brings us together every summer to present its new devices (foldable, it’s no secret where the shots are going) in an event that points out ways. Last year it was in New York, this year it is in London and, as it could not be otherwise, you will be able to follow it live and direct with us. Galaxy Unpacked will take place today, Wednesday, July 22, at 3:00 p.m. Spanish peninsular time. You can follow it live through from our YouTube channelof our live page and from our Instagram profile. The schedules according to regions are as follows: Spain: 15:00 (14:00 in the Canary Islands).

Live What we hope to see At the beginning of the year, within the framework of MWC, we learned about the Galaxy S26 Ultra and its brothers. The most conventional high-end is already on the table, so now is the time to get to know the new folding ones. Samsung renews its folding devices every year and around this time, aka the Z Fold and Z Flip, as well as smart watches. There have been various leaks that bring winds of change, but the most interesting is the one that came from Samsung itself. The firm published a series of very… suggestive videosin which he made us understand that would launch a new format. A third foldable? The evolution of the Fold or the Flip? We don’t know, but the company has something in the oven. Regarding the watches, it is to be expected that, having been completely renewed last year, in this event the improvement will be somewhat more incremental. We will surely see improvements in the battery, screen or performance. Samsung also has an outstanding debt with your glasses with Android XR and At Google I/O we saw a preview of what they have in the oven, so since dreaming is free… We will clear up doubts in a little while. We remember: the event will be today, July 22, at 3:00 p.m. Spanish peninsular time. In Xataka | Follow Samsung’s Galaxy Unpacked live

In Almería they thought they had seen a drug boat. It turned out to be the solar yacht of a Finn who has traveled 6,000 km without refueling

by

The bathers who tried to suffocate the high temperatures of the latest heat waves swimming around Cabo de Gata last sundaythey watched in astonishment the passage of a very unusual boat. It sailed close to the shore, with a lower hull than usual and an extremely quiet engine. It had no mast or visible bridge. Some thought it was a drug boat. Others, directly, in a submarine. It was nothing like that. According to collected Hybrids and Electricswhat was crossing Las Salinas was the Helios 11. When a Civil Guard patrol boat, equally surprised by the appearance of the boat, came to closely inspect that boat on El Zapillo beach, it only found solar panels and batteries. The dream of a Finn who wanted to sail cheap The person that the Civil Guard found on board the boat is Lukas Sjöman, Finnish adventurer, designer and builder of the most sustainable yacht that the Andalusian coasts will see this summer. He built it alone, without a shipyard, in a shed at his house and its price has not exceeded that of a modest car. As Sjöman himself tells in the videos from his YouTube channel, it took about 200 days to have the hull ready, made with a structure of marine plywood and fiberglass. The result is a yacht 11 meters long and 2.4 meters wide, weighing close to 1.5 tons. Inside there is space for some amenities including an electric stove, a light refrigerator and a bathroom with cisternjust enough to live on board, but without the luxuries that millionaires’ yachts usually equip. However, Sjöman’s obsession is not sailing through the most exclusive ports of the Mediterranean. emulating Koru of Jeff Bezos or the superyachts of Arab sheikhs. Their goal was to create a boat that was as sustainable as possible. To achieve this he only had to do one thing: look at the sky. The entire roof of the Helios 11 is covered with solar panels, and as it says on your channelreaches a power close to 6 kW and an expansion to 40 kW is already planned. The system runs on 48 volts and charges the batteries while the boat is underway. The electric motor supported by solar panels allows almost infinite navigation since it does not need to stop to refuel like alternatives with diesel or hybrid engines. Sjöman assures that the boat consumes less while sailing than a domestic blender. On a normal day it travels about 145 miles, about 270 kilometers. In bad weather, the decrease in the charging capacity of its batteries and the greater demand for power during navigation to overcome storms, the figure can drop to 40 miles (about 70 km per day). Helios 11 sailing near the coast A 6,000 kilometer trip to put it to the test And what’s the best way to test that a boat really works? Effectively taking to the sea. Sjöman began a journey of thousands of kilometers to demonstrate that the Helios 11 is a viable alternative to build cheap yachts and with propulsion systems that do not depend on fossil fuels. The Helios 11 route started in Finland and went down rivers and canals, crossing several European countries until reaching the Mediterranean. Sjöman arrived in Ibiza after going through some 5,700 kilometers without refueling. From there he continued his particular Mediterranean cruise approaching the Andalusian coast: Mazarrón, Cabo de Gata and now Almería. Helios 11 anchored in Ibiza The trip has not been perfect. According to collected Supercarblondiewhen he was anchored on the coast of San Carles de la Rápita (Tarragona) his auxiliary boat was stolen. So he had to build another one to continue because the Helios 11 cannot anchor on shallow beaches or in small docks to resupply with supplies, so without the boat the Finn was left “incommunicado” on board. Solar energy solves fuel. It does not solve the logistics or unforeseen events of sailing alone. A clean alternative to the most polluting yachts Current superyachts take more into account comfort and nautical luxury than the emissions from their engines. The few hybrid alternatives that alternate electric and diesel engines are aimed at obtaining quieter navigation and anchoring, not to reduce emissions. According to the report ‘Carbon emissions inequality kills Elaborated by Oxfam International, the yachts of the richest billionaires generated in a single year a carbon footprint which is equivalent to 860 years of emissions from the average person. The problem with these boats is that, as the seized superyachts to the Russian millionaires for the war in Ukraine, they must keep their engines running to feed the air conditioning that prevents the noble materials inside from deteriorating, generating fuel consumption of several thousand dollars a day.
