Years ago I bought a computer that turned out to be a chestnut. Almost for the same price, this gives three (or more) turns

A few years ago (not too many) I bought a computer that would be destined to work exclusively. It turned out to be a bit brown. I spent approximately 620 euros and, although I did not have a bad technical card, the experience was very different from what I expected.

A few months ago Irobot, the company behind the sheeled vacuum cleaners, He gave a twist to his catalog. Since March, Irobot has three ranges: The Roomba (entrance range), the plus Roomba (the mid -range) and the Max Roomba (the high range). The first two already had members, but the flagship was still in the air. And if we talk in the past it is because it is here. His name: Max 705 combo. A two in one with several tricks. THE ROBA MAX 705 COMBO (Do not confuse with the Max 705 empty) It is a robot that sweeps, aspires and passes the mop. Nothing out of the ordinary, until we see how it does. The device has two anti -re -gum brushes to better reach the edges (although they do not move to the sides as other models), a central brush that aspires to dirt and a roller -shaped mop that is, without a doubt, the main protagonist. Roller. The mops passed smooth rags to circular mops and the next step seems to be the mop-rodillo. This system, baptized as Powerspin, consists of a roller that rotates 200 times per minute and is cleaned in real time with new hot water. The dirty water is collected with a small shovel that, in theory, should also improve the spongy of the mopa on the march. And the edges? Although the Roomba Max 705 Combo has no telescopic brushes, it is able to move the roller to the side so that the corners and edges do not remain without scrubbing. It also has a retractable protective cover that is placed under the mop to prevent the carpets from wetting. It is a system that, indeed, reminds a lot of what is proposed by Dreame in its recent Aqua10 Ultra Roller. Irobot Roomba Max 705 Combo | Image: Irobot Navigation. Irobot has set aside the classic Lidar Superior and, instead, has integrated it into the device. Thus, the robot is able to create 3D house maps for smarter navigation, automatically assign each room and move in the dark. As for the camera, it is placed on the front and recognizes cables, socks, pet depositions and if the dirt is dry or wet. Irobot Roomba Max 705 Combo | Image: Xataka The base.

The AI has folded the price of an ultrarrao metal. The problem is that we need it to store renewable energy

Two technological revolutions are redefining, at the same time, the entire energy sector: the transition to renewable sources and the unstoppable boom of artificial intelligence. The first needs cheap and efficient batteries. The second has an insatiable data appetite and needs hardware to store them. The problem is that both are colliding in the market of An ultrarrao metal: Ruthenium. And the AI is winning the battle. Ruthenium is in historical maximums. In the last year, this discreet silver gray mineral has become The unexpected star of raw material markets. Its price has doubled, reaching $ 25,720 per kilogram, according to data from the Johnson Matthey metal refining that Bloomberg collects. The figure not only eclipses gold or silver increases, but also touches its historical maximum of $ 27,970, reached 18 years ago. What has unleashed this fever. The answer is in data centers that feed artificial intelligence. Ruthenium, a Platinum Group metal, is exceptionally hard and versatile. One of its applications in electronics are high -capacity hard drives, which use a river layer of less than a thick nanometer to greatly increase data density. As the generative AI and the Cloud Computing They demand to store astronomical amounts of information, the demand is triggered. But the background problem is scarcity. Ruthenium is one of the most rare elements of the earth’s crust. It is obtained almost exclusively as a byproduct of platinum mining, and its annual supply is tiny: just 30 tons last year. Unless the investment in mining increases, analysts expect the market Enter in deficit next year. That is, the demand exceeds the supply. Not only does it need Ruthenio. In addition to hard drives, metal is a vital component in Several of the most promising chemists For massive energy storage batteries. Ruthenium oxide offers unique capacitance and loading and discharge speed, so It was intended to be used in Super Current before the AI duplicate its price. It is also a necessary metal In lithium-oxygen batteriesconsidered one of the next great revolutions in batteries for its very high energy density. But these cells depend on efficient catalysts. Ruthenium nanocatalysts achieve extraordinary capabilities and life cycles, but with the current price they are unfeasible. How it affects the energy sector. No sector is able to face investments as large as that of artificial intelligence. The AI is staying with the Ruthenium to save data while the entire planet faces another urgent challenge: store energy to abandon fossil fuels. Intermittent renewables, such as solar and wind, need large -scale batteries to keep the energy they generate when the sun shines or the wind blows, being able to use it later when night falls or the wind stops blowing. According to the International Energy Agencyin 2023 42 GW of capacity in batteries were installed, more than double than the previous year. It is an impressive, but insufficient figure to meet the objectives of the Paris Agreement. The world needs to multiply that rhythm by six and reach about 1,500 GW of storage capacity from here to 2030 (of which 1,200 GW would be batteries). Is there any alternative to Ruthenium? There are other technologies that allow storing large amounts of data, but they are very expensive, so the industry continues to bet on ruthenium. In fact, a report by International Data Corp. provides that sales of hard drives with Ruthenium will increase 16% this year, dragging metal stocks. Researchers from all over the world have spent years developing new advanced batteries assuming a price for ruthenium that, although high, was manageable. Now, the explosion of the demand for AI has created a cost curve that no one anticipated, and that forces to start from scratch.

A trough ready to free us from the scorching heat, but charging its price on storms

The worst of this warm episode has not yet arrived but there are those who already have their view at its end. It is not for less, as it is customary this summer, the only thing that is helping to reduce the thermometers is the arrival of storms. And again meteorologists foresee them. Change the trend. On Friday part of the peninsula will see A new transition Meteorological: The heat episode we now live will give way to storms. These stormy episodes will affect the north third and could be strong, leaving winds of intensity and hail. Dorsal and trough. Again, the alternation between scorching heat and intense storms is given by the succession of dorsal and trough, air masses in height under the influence of high and low pressures respectively. According to explains the geographer Samuel Biener in Meteoredthe change in the situation will come from the hand of an Atlantic trough driven in turn by the undulations of the stream in jet. Two seas to red live. There is another important element in the risk that these storms suppose in summer, Remember too Biener himself. It is in the seas, and more specifically in the temperature of its surface waters. Both the Western Mediterranean and the Eastern Cantabrian They are suffering their own “heat waves”. The waters of the surface in these regions have been accumulating several degrees above what would correspond to this time of year. This increases the risk of convective storms. Heat and moisture are transmitted to the air on the surface and then this air interacts with possible cold and dry air masses such as those dragged by the rush that approaches, generating important storms that discharge the humidity and energy accumulated in the environment. Uncertainty, for now. There is still uncertainty about the evolution of this new episode of storms but The forecasts From the State Meteorology Agency (Aemet), on Friday both cloudy skies are expected and “locally with a storm” rainfall. These will circulate from the west and will end up affecting most of the north third, being especially intense in the Eastern Cantabrian and Western Pyrenees. The situation is expected to refer towards the afternoon of Saturday, although the forecasts indicate the possibility that during the day there will be “strong and accompanied by storm” rainfall between the Eastern Cantabrian and the Northeast of Catalonia. For now the agency has not issued any warning related to these storms, but it is still early to rule out a worsening of the situation.

Dreame just presented your new series of aspiring robots and the first member of the same. With the Aqua Series, the company wants to give a twist to the scarf and its new Aqua10 Ultra Roller It is the best proof of this. Because yes, this robot aspires and passes the mop, nothing new, but it does so in a way that we had not seen to date and that promises interesting changes: with a rotating mop that is cleaned in real time. Dreame’s thesis is simple. When An aspiring robot passes the mopadirt stays in it and walks throughout the house for a simple reason: the mop is the same. If the robot passes through the bathroom or kitchen, where there may be dirt or fat, the cleaning will be harmed in the rest of the rooms and we can face cross contamination. This there are ways to avoid it in some high -end models (programming a return to the base and cleaning of the mopa after finishing x rooms or a specific room), but makes cleaning time increase a lot. Dreame’s proposal goes one step further and is, as little, curious. Scheme of the roller -shaped mopa of Dreame Aqua10 Ultra Roller Complete | Image: Xataka A MOP that revolves … Instead of a simple mop or a circular mop as we have seen in other models, the Dreame Aqua10 Ultra Roller Complete Mapa is rolled up. While the robot passes the mopa, this tour of 100 revolutions per minute and is cleaned in real time with new water thanks to a system of 12 spray nozzles. Simultaneously, a flush eliminates dirty water, which is stored in a separate tank inside the robot itself. … what is combed …. Another problem that conventional mounts have is that they are caked with use, especially if there is a lot of dirt on the ground. To avoid this, Dreame has implemented a system called Fluffroll that, basically, is a kind of roller/comb that rotates at 1,000 rpm in the direction of the mopa. This comb, they affirm from DREame, maintains the spongy mop and with the loose fibers, something that, on paper, should get cleaning uniform throughout the process. Bottom of the aspiring robot. Here we can see the size of the roller (which can be moved to the side to reach the edges) and the anti -edge combs | Image: DREame … that hides … Dreame has not forgotten carpet users. It is common for high -end robots to be able to raise the mopa and prevent contacing the carpets, but Dreame has taken another step. The mop does not rise, but has an automatic closure, a kind of barrier, which is automatically activated and prevents the mop from touching carpets or dripping. … And that is cleaned with heat. When the cleaning is over, the robot will return to the base, it will be emptied and the cleaning of the mop will begin. As? With hot water at 100ºC. According to me, this system should be able to dissolve fats, discourage dry dirt and eliminate odors, bacteria, etc. When it passes through a carpet, the robot itself covers the mop to prevent dripping | Image: DREame What else? Although the novelties of the mop are, without a doubt, the most striking, the Dreame Aqua10 Ultra Roller Complete is stored other tricks under the sleeve. For example, it has retractable robotic legs that allow you to overcome small steps of up to six centimeters. It also has two HD cameras with NVIDIA ISAAC SIM and Reinforcement learningan upper retractable LDS sensor, 30,000 pa for suction power and, of course, the roller moves to the side to clean the edges and corners well. On the basis. The base not only works as a cargo station, but also cleanses the robot and keeps it ready. In that sense, it has a clean and dirty water deposit and solid tank. Like other company models, it is possible to connect it to a water outlet and exit at home so that maintenance is more automatic. The base can be used or can connect to a water outlet with an accessory | Image: DREame Price and availability. As explained by Dreame, the device will be put on sale from the fourth quarter of 2025. Details on the price will be confirmed later. We will update this article as soon as we have more information.
