A startup wants to build the “Tesla de los Barco”. His revolutionary idea is to put candles

by

Transport electrification and the search for alternatives to traditional combustion are priorities for many countries. While Europe and China They bet on him electric car and aviation explores more sustainable fuelsmaritime transport of merchandise continues to depend almost completely on diesel. Although the most Of world trade, it is rarely mentioned in the conversation about sustainability. However, a company is already working on changing this And that solution is an millenary technology: candles. Pollution. To meet the tremendous commercial volume we need at the moment, we use huge boring ships. And, although the focus is put on other forms of transport, the maritime is a significant source of pollution. HE esteem that the sector produces 3% of global CO₂ emissions and other particles that contribute to global warming. Specifically, it is responsible for 15% of nitrogen oxides emissions -Nox- and 13% of sulfur oxides -sox- that humanity produces. He guilty It is the fuel used, with high amounts of sulfur and heavy metals, but the regulations allow ships contaminate up to 500 times more than land vehicles. At full sail. Therefore, measures are being implemented to mitigate the polluting impact Of the great ships such as speed reduction, more respectful fuels either systems carbon capture within the ships themselves. But there are also those who are exploring other ways. Show this is the Yara Birkeland boat That not only works thanks to a cover full of solar panels, but does it autonomously. Another example is a design of the British company Windship Technology that bets on technology thousands of years ago: candle. Or a kind of candle. The ‘Tesla de los Mares’. Presented A few years ago, the True Zero Issation is a ship or propulsion project that allows the CO2, NOX and SOX to eliminate, as well as any other polluting particle, of the navigation equation. The idea of ​​the company is for the ship to work with a diesel-electric energy system and, to ensure that there are no emissions, carbon captors would be installed. In addition, the helmet would be optimized to offer the lowest possible resistance to water and would have software that draws the best possible route taking into account variables such as weather forecast, distance, currents and the state of the sea. But it is clear that what attracts the most attention is the candle system. 21st century candles. Unlike traditional candles, which generate wind resistance to propel the ship in the opposite direction to that current, the Windship design consists of several masts with three wings that what they are looking for is to attract the wind to, next to the electric motor, optimize the movement of the ship. Each of these platforms can be up to 48 meters high, something that adjusts depending on the size of the ship and is mobile, oriented to take advantage of the currents. Challenges. At the moment, there is no ship designed with this base system, and it is not something that seems simple. The reason is that the boring ships have their load surface, precisely on the deck. Except for Roro shipsdesigned as large covered garages, the containers transport their load on the deck, which raises a challenge: the candles would occupy valuable space and could interfere with the port operations. From Windship already comments that the structure of the mast can be folded to facilitate maneuver and that its useful life is greater than 25 years, but it is clear that it is an added challenge for ship designers. For now, who has interested For technology is DNV, an insurance organization in segments such as oil, energy or maritime industry. Superyates. Although these large load ships are heavyweights in naval pollution, where a system like the one that Windship poses in luxury yachts can have more future. David Barrow is the Windship technology director and Comment that, although the strictest regulations have not yet affected the superyates, with the environmental objectives marked By 2050, it is possible that these vessels are also wrapped in the restrictions. Being much lighter than the large charges, a yacht of about 70 meters with three masts of 35 meters each could reach the same speed that current engines provide. That, of course, would lead a redesign in the construction plans so that they are more “dynamic and with better stability. Traditional sailboats. The Windship solution is evident that it is avant -garde, but there is another company that literally bets on candles. By sailboats to transport merchandise, specifically. It’s about Towta French company that completed a pilot trip with its ship a few months ago Anemosa sailboat with carbon fiber masts, traditional candles that are deployed by remote control and two diesel-electric motors. Anemos is the first of a projected fleet of eight vessels that, according to Towt’s calculations, would transport 200,000 tons of merchandise every year, saving with its impulse to candles about 40,000 tons in CO₂ emissions. The ‘anemos’ In the end, to candles or not, it is evident that manufacturers should look for alternatives to current fuels if they want to adjust to restrictions based on achieving the decarbonization objectives. And it would be curious to see non -competitive ships driven thanks to new generation candles.

To build the longest world bridge, China turned to a peculiar material: bamboo

by

Although Saudi Arabia and Arab Emirates are immersed in a particular war for have the most beast buildingstalking about megaconstructions is to automatically look at China. The Asian giant has some of the works more tremendous, impossible bridges and even Higher abandoned skyscraper in the world. And one of those pharaonic constructions is the Hong Kong-Zhuhai-Macao bridge. With a length of 55 kilometers, it turns out that it is not only formed by steel and concrete: the secret ingredient is bamboo. And according to those responsible, continue like the first day. The bridge. After six years of planning and another eight of construction, in 2018 China opened the imposing bridge that connects Macao and Zhuhai. Its 55 kilometers, 6.2 of them underground, allow to convert a trip that previously lasted three hours into a ‘walk’ of just 30 minutes. And something that resonated in its day was the 420,000 tons of steel (which would be equivalent to 60 Eiffel towers), its more than one million cubic meters of concrete and the flexibility necessary to support typhoons and earthquakes. It is a barbarity, with an underground stretch that disappears and emerges from the sea It looks like a ship, but it is one of the two inputs/exits of the sea Bamboo. It turns out that the mixture added a plant: bamboo. And it is something that is not so weird, since, as we can read In South China Morning Post, China is the largest bamboo producer in the world and is something to give way. In the aforementioned bridge, this element was used on the panoramic platforms that are found throughout the same and the official newspaper Science and Technology commented a few days ago that, after six years installed, these panels have resisted sunlight, typhons and The corrosion of seawater, keeping “as solid as ever.” One more element. Lou Zhichao is a member of the Bamboo Research Institute of the Forestry University of Bamboo and pointed out that, apart from in China, bamboo occurs mainly in developing countries, which gives China a unique advantage and position to the time to process this bamboo. His team, in fact, has been developing more advanced technologies to process bamboo a decade, causing the process to emit less co₂ while encouraging the use of bamboo under constructions due to a relationship between resistance and weight higher than some alloys of some alloys of some alloys of steel. In addition, it can replace wood, plastic and steel itself in some constructions. Bamboo II. Now, although it has interesting properties, it also has a problem: it is prone to decomposition. This means that when bamboo facilities are done, toxic preservatives must be used that make the material much less ecological. The chickens that come through those that come out in environmental matters, basically. And, precisely, the Zhichao team has been working in recent years. One of its latest advances in research is a heat treatment that eliminates nutrients that cause the accelerated decomposition of the material. This allows to reduce its processing time by 50% while increasing durability outdoors without antimoho treatments. Adolfo Suárez Madrid-Barajas airport. You don’t have to go to China to see great structures in which bamboo is clear protagonist. In Spain we have examples such as Madrid airport Adolfo Suárez Madrid-Barajas, in which the roof of terminal 4 is formed by lames 100 mm wide of bamboo sheet. In total, there are 200,000 m² of bamboo with fire resistance and was the ideal material due to the peculiar curved forms of the terminal roof design. It is also a material that was raised for the Futurist Ciudad Oceanix City And the protagonist of the bamboo towers that Paris wants to build for 2050. And scaffolding. Beyond in places as punished as a bridge in such a complicated area and applications in other buildings, bamboo is absolute protagonist in Hong Kong. Specifically, in its skyscrapers, like an exoskeleton that really is a system of Scaffolding During the construction of buildings. For the rest, Zhichao continues to work to expand the use of bamboo as high quality material for several reasons. One because it absorbs 50% more co₂ than common trees. Another because it is estimated that its crop and market benefits some 50 million people throughout the country. And, therefore, he hopes that the government “finance the development of key technologies and reinforce regulation by national and local standards to boost the industry.” Industry tech. Apart from in structures, bamboo is positioning as a material that can be very useful in other sectors. An example is that of consumer technology not as an element that goes within the devices, but as part of the packaging. A few years ago, on a visit to the Innovation Center of Lenovo, They told ushow they were starting to use bamboo in the boxes of their laptops. Bamboo box to the right. On the left too, but after a year underground. The reasons were environmental due to the degradation of their fibers in normal conditions in nature. In fact, it can be buried directly in the garden to use it as fertilizer. In the photo that we leave just on these lines you can see two boxes, one new and one after a year underground, to appreciate its degree of decomposition. And, that sustainability is one of the keys (along with many others, of course) of decarbonization.

Valencia faces a serious problem with housing. So someone has had an idea: build more height

by

Tecnocasa recently published A report in which the thermometer to the Spanish real estate market, a theoretical exercise that allowed him to obtain two revealing data: in just one year the demand for housing has grown up on average 39% In Spain while the offer undertook the opposite road, retreating more than 9%. The result is a tensioning market, in which the floors last a few weeks or days (even hours) announced in real estate agencies before finding tenant or buyer. In Valencia, an idea has emerged to alleviate that problem and reinforce its public housing offer: allow buildings to gain height, a formula with which they calculate that the city could win More than 70,000 floors protected What happened? That in Valencia has been on the table An idea New to reinforce your housing park. At least the protected housing. A few days ago the Socialists proposed in the City Council of the City Council to retouch the local ordination (PGOU) so that the city buildings grow to the top. Literally. His idea is that the blocks can raise one or two plants their height. The plan He advanced it The country Wednesday, before the commission; But from the PSPV they recognize that he did not obtain the necessary support, so at least for the moment he will stay in that, an idea about the table to face the housing problem. “The PP has rejected our proposal”, Explain The socialist mayor Elisa was worth. Click on the image to go to Tweet. What have they raised? “Raise buildings to gain public housing”, summarize The PSPV of Valencia. The idea is simple: modify the PGOU to upload the city blocks one or two levels. The socialist group has already made accounts and calculates that if an extra plant was added to all buildings, 86,644 homes would leave, a large residential park also distributed throughout the municipality. As part of these constructions are protected by their heritage value or are located in Valencia neighborhoods in which height cannot be gained, the PSPV has retouched that initial figure, but the result remains considerable. “If we subtract 20% for understanding that in the historical centers and protected buildings you will not be able Explain Valía to The country. That (more than 70,000 new floors) is the figure that PSPV presumed this week in networks, where he claimed that his proposal “would avoid expulsion and uprooting.” Why such a measure? The PSPV plan is focused on the creation of protected housing (both for rent and sale) in a territory that dealt with the offer shortage and the price increase. In January the Polytechnic University of Valencia (UPV) published A report that helps to understand much better The situation From the capital of Turia: in five years the prices of the new work have triggered about 80% and the offer was reduced by 83%. Things have not been better in the rental market, which became more expensive. “What we have before us is a tsunami of epic dimensions and all administrations must act in a coordinated, effective and quickly, The director explains of the Chair of the UPV Housing Observatory after remembering the forecasts at the state level. “We estimate that more than 80% of the current demand fits in the public protection house, so the determined commitment to the construction of this type of housing is strategic.” And how do you want to do it? The PSPV proposal is not entirely new and there are other cities in which they have already been activated similar solutionstaking advantage of the ‘Flight Law’. In Valencia the idea is that it is the communities of owners themselves that can promote the ‘stretch’ up the buildings with one or two extra plants. The resulting floors would be added to the Public Protection Housing Park, which among other things would allow it to extend it to “consolidated neighborhoods”, Valía points out. The PSPV plan also includes an extra advantage for neighbors communities. In a city with an aged real estate park, in which A notable percentage From the houses it has more than four decades, the communities of neighbors would obtain from the extra buildability some resources that would allow them to modernize their blocks. Are there more cases? Yes, Valencia is not the only one that has been fixed in that formula. In Barcelona, ​​licenses have been granted to lift floors that increased the buildability of existing buildings. In 2017 it was estimated that in just three years they had benefited from that possibility (the traces) about thirty buildingswith licenses for 120 floors. Madrid too It has varied Over the years the maximum height of its buildings and the Balearic Islands leave another recent example. Palma already added in September 70 requests of buildings to grow in height and add 589 floors of limited price.

Trump orders to build an anti -mile shield “iron dome” for the USA.

by

President Donald Trump ordered by Decree on Monday the construction of an antimile shield of the “iron dome” type for the United States, like the one that Israel uses to intercept thousands of rockets. “We need to immediately begin the construction of a state -of -the -art antimisile defense shield, the iron dome,” Trump told Republican congressmen in Florida. Hours later, aboard the Air Force One that led Trump to Washington, a White House official confirmed that the president signed a decree “To develop an ‘American iron dome’, an antimile defense shield to protect the US territory.” The name “iron dome” comes from the system installed in Israel since 2011 which has allowed neutralizing thousands of rockets against their territory. How does the antimile defense system work iron dome? In the case of Israel, each system consists of a radar unit and a control center, which can detect approximate projectiles, such as missiles. After taking off, calculate your career and your goal. It happens in seconds. You have to do it, because depending on the distance from the Gaza Strip, the Israelis only have 15 to 90 seconds to be safe from a missile that is approaching. The third element is missile launches. There are three to four per system, each with space for 20 rockets. A defense missile is only launched when it is clear that a projectile is aimed at an inhabited area. It is maneuverable in the air. The interceptor missile does not directly impact the other projectile, but exploits in its vicinity, destroying it. However, the debris that fall can cause damage. The systems are mobile and can be relocated. Ten of them are currently in use in Israel. According to the manufacturer, the Israeli state defense company Rafael Defense Systems, a single battery can protect a medium -sized city. The system can intercept projectiles with a range of up to 70 kilometers. According to experts, 13 systems would be necessary to protect the entire country. How reliable is the system? The manufacturer declares a 90%successes. The head of the Israeli defense organization Antimisiles, Moshe Patel, told the AFP news agency that until January the iron dome had intercepted more than 2,400 projectiles in the last ten years. The arms manufacturer Rafael figure in more than 2,500 launches successfully. “Any intercepted missile would have impacted an inhabited area, which could cause serious damage and cause victims”is stated on the website of the Armed Forces of Israel. According to the Israeli army, during the current escalation 1,600 projectiles against Israel were shot, of which it is said that 400 fell into the Gaza Strip itself. The Radical Islamist group Hamas seems to bet on the strategy of launching large full -successing downloads and testing the iron dome or even taking it to its limits.

If the question is who wants to build the world’s largest data center, the answer is surprising: India

by

The data centers is the new gold fever of technology. That Mukesh Ambani, the founding billionaire of the company Reliance Group. His intention is to go beyond what the great American technological ones promise and build in India the largest data center worldwide. 3 GW. That is the energy capacity that Ambani projects for a new data center that wants to build in Jamnagar. This is stated by sources close to the project In Bloomberg. Akash Abani, CEO and son of the founder, said in a recent statement that they were building a data center in less than two years “as we have always done in – in 24 months.” An irreverent figure. At present, the largest mute data centers are below 1 GW of energy capacity, as indicated in Bloomberg with data from the DC Byte consultant. In visual capitalist They showed a year ago the largest data centers in the world. To be able to compare with the Indian project, a fact: all AWS data centers in the Northern Virginia region, in the US, about 300, add a total of 2.5 GW, when one in India could have more energy capacity that all those United centers. Amazing. The most capacity data center in the world is currently from Microsoft in Boydton, Virginia, with almost 600 MW of energy capacity. The more energy, the better. Data centers are usually measured by the energy they can provide to their servers, their cooling systems and the rest of the equipment of these facilities. The larger the figure, the more computing capacity, and here the AI ​​models have created a career to build more and larger data centers. Ambani for all. The tycoon is known for his aggressive tactics to have his rivals with price wars that few can sustain. It happened in the mobile segment and now wants to take the strategy to AI. Its objective is to reduce inference costs to a minimum to become an absolute reference in this market. This was stated In a statement highlighting that “our goal is to create the cheapest artificial intelligence in the world, right here, in India.” Astronomical cost. However, it is not clear how Reliance will finance this potential operation. According to Bloomberg estimates, a data center could have a cost of between 20 and 30,000 million dollars. Reliance Industry, the main division of the group, has about 26,000 million dollars. Jamnagar. The Indian city has a population of 650,000 people. There is the refining and petrochemical complex of Reliance, the largest in the world, but also Reliance wants to build there a renewable energy complex huge These energy sources would be especially used in that data center. Stargate in the spotlight. These days there is much of what to talk about in data centers, especially after the announcement of Openai and Softbank of PROJECT STARGATE to create a series of data centers in the US with a gigantic investment of 500,000 million dollars. There are no specific details of the energy capacity that is discussed in that case, but with that investment that data would be equally colossal.
