[000:00:00;00] equivalent, according to some sources, it was precisely because of such a cosmic block that dinosaurs died out only more than 66 million years ago. an impact in the area of ​​​​modern mexico caused changes on the entire planet. the fall of a celestial body with a diameter of only 1 km, according to calculations, can lead to a global catastrophe and today there are more than a thousand suspicious asteroids, for which they try to observe the greatest danger are asteroids that fly from the side of the sun, let's say, i have everything, the sun. as you can see it shines very bright and because of this , an asteroid flying from the side of the sun, and we will see the very last moment. well, in fact , we will not have time to neutralize the threat of an asteroid hitting the earth. but if scientists notice a dangerous celestial body, at least in 10 years, will they have time to prevent a catastrophe? in the moscow planetarium, fragments

of various asteroids are collected, some resemble precious stones, others are porous volcanic glass , better known to us as foot pumice. each has its own composition of metal stone mixed that is why the famous film armageddon for example, did not know in advance. what kind of drill is suitable for a cosmic body threatening our planet, according to the plot, people landed on an asteroid , explored the soil, drilled a well , loaded an intranuclear charge and blew up a cosmic body. so its fragments flew past the earth. it looks beautiful, but experts can list it point by point. in what the film is far from reality , soft soft landing to extinguish the huge speed of body movement, how to breed this landing is presence of gravity? that is, it is certainly there, but it is insignificant, it is malach to walk, therefore the body, that is, it is combustion

that occurs in the absence of an atmosphere that cannot be present on asteroids. although they showed something similar to the atmosphere, but also the actual power of a nuclear charge. what must be in order to destroy this body? scientists have proposed many more real, although also fantastic, ways to deal with dangerous asteroids. for example, there is an idea to change the trajectory using the gravitational towing, a giant spacecraft should hover over the asteroid for years. acting on it with the power of its ion engine and causing it to deviate, another version of the laser bee is a swarm of miniature laser devices that are sent to the asteroid will heat parts of its surface, and it will turn into gas that will create thrust. you can paint an asteroid black with soot or white with titanium dioxide, so that thermal radiation again changes its trajectory to blow up a celestial body,

a risky option, popularizer, cosmonautics, denis prudnik shows that there may be consequences of a conditional asteroid - it is a transparent ball with beads, and the fist did not fall out of the troll projectile. on the one hand, our large asteroid turned into a bunch of small asteroids, the power decreased, but on the other hand, the radius of destruction increased. as you can see from this picture and also the next problem, that the fragments scattered unpredictably, if we look at our three green fragments, then on the one hand we could save the earth from a collision, since we could be inside this triangle itself, but on the other hand, the earth could also be in the path of each of these fragments and the main task is not to hit the asteroid. we wouldn't decide the most realistic, moreover , the now tried and tested celestial tarant

idea is to take a spaceship and push an asteroid with it. here are two astronauts in zero gravity showing themselves schematically. how it works in 2021, nasa has manufactured and launched a special device the size of a refrigerator and weighing 570 kg program. wali dart is translated from english as a dart, and its results exceeded all expectations. the umbrella, justifying the name, crashed exactly into the target body called a dimorph asteroid satellite. i slowed down its rotation and changed the trajectory even more than the calculated one due to the formation of a dust tail, that is, i proved the practical possibility of preventing a collision with the ground in this way, of course, an experiment. so far, it has been successful on a very small celestial body and there is still a lot of work to be done to confirm the effectiveness of the method on larger and faster objects. will the hard the equipment to reach the target on time and

whether there is enough power to knock the threat astray, scientists continue research on the eve of 2046, when the next asteroid may go dangerously close to the earth. at least we have hope. in addition to tests and checks on the air of the miracle of technology, there is always a news section of the top 5 messages that i personally found to be the most interesting this week . we start from the fifth position. an unusual way to control rodents and pests of crops was developed by scientists from australia. suggest spraying the fields with diluted wheat germ oil to make the whole fields smell attractive. experiments on real land in the state. new south wales showed that so discouraged mice cannot determine exactly where the sown

grains are located and do not dig them out of the ground , the reduction in losses due to this treatment ranged from 63 to 74%. this is a marvel of technology. in our issue, deception instead of hot water appears with a characteristic smell that is somewhat reminiscent of rotten eggs. what unfulfilled promises give manufacturers of water heaters dirty in the kitchen. is it true sponges for washing dishes and the step of bacteria sponges, i think this is a time bomb of the moscow ring road to decontaminate them. and right or those who buy sponges from unusual materials, the mosquito net is not like an ordinary paralysis very quickly, as it will manifest itself in a country house and in a tourist tent, as well as the best discoveries and inventions from all over the planet. the most

father is in the hall. what are you doing, lord, let’s get lost at 23:20 on ntv techniques, i’m sergey molodev, we’re climbing higher in our hit parade of news from the world of science and technology, that on the fourth line they will be able to drive straight into their apartments by car they are going to build a project in dubai introduced one of the companies known primarily for its luxury cars, except for the catchy design. the building will be distinguished by the presence of large elevators designed just for entry by car. is one heated teapot enough to

dilute it later and perform morning water procedures? as a former chelyabinsk student, i know that if it’s economical, then it’s quite, well, if you are a woman and you have long hair, as soon as summer begins, residents of large and small cities are tormented by hot water outages and from time to time they think whether to buy for these weeks the heater and fall into the trap of choosing it is so large and varied that you can get confused. main the question is, is it necessary to buy, and then look for a place for them and mount large storage boilers with a tank, or can you get by with something more compact? alexander chebanov from the moscow region has been using an instantaneous water heater with automatic control and built-in memory unit for 5 years . that is, he simply remembers

the last value and exposes it on foot. i turn it on, it turns out somewhere a few weeks a year. so it doesn't work all the time. so that everything suits him. is it true. there is one caveat, such a model will cost approximately 15.000 rub. to other users who have bought similar but cheaper devices. lucky less journalist. anna manikova chose an inexpensive flow-through heater for 3,500 on the advice of her friends, but something went wrong with him and cursed, because it turned out that he really started and you feel such a tingling sensation. indeed, like electricity, you do not feel safe when you receive it. anna's husband had to disassemble the device and change its design, leading the wire to the water tank, our permanent expert physicist. vladimir

reshetov explains that initially there was no grounding here and the problems disappeared when it appeared thanks to skillful hands on this case voltage. no earth, this water heater worked, it bit when it was not grounded, people grounded it and everything became normal. we also bought and tested for electrical safety two other machined heaters, those models that buyers often complain about, write that these devices often fail, the cost of the first was 6,000 rubles. second 2.400. both that we got the device turned out to be serviceable, but their cheapness can go sideways. corrosion protection is not very good, in order to protect it from the road, it is necessary to connect it only with grounding, and preferably also through the pattern of the device. protective shutdown when closed, correctly turned on water heaters do not pose a danger to life, there are exceptions. this is a

twelve volt car heater. there, about the same, he corroded his corrosion and the wires were exposed. in this case, grounding. might not help. in this case it should work safety shutdown feature users of instantaneous water heaters often complain about weak water pressure and insufficient heating. and it is not surprising such a device. should instantly heat the jet passing through it. and the stronger it is, the greater the peak power should be. this is a serious load on the device itself and on the power grid, so most of the machined heaters, so that the corks do not drink, are actually specially made low-power, but for those that heat up properly, you will have to lay a separate thick wire from the electrical panel. yes, they are worth it. they are more expensive, so it's still not necessary, so just reject it right away. the installation of a classic drive, it is less demanding on the network , brings the water to the set temperature slowly

over several hours , it does not need a small peak power. and what is interesting about consumption , together with engineer denis nikolaev, we conducted a test in which the flow and storage device heated the same volume of water 50 liters, it took 1.43 kw / h to bring it to thirty-eight degrees for the flow device, the boiler, stretching the process for 1.5 hours, heated up to 51 °, but spent much more than 2.25. kw / h, denis nevertheless believes that if it comes to significant volumes of water , the storage tank may turn out to be more economical than the storage heater allows you to save electricity, and due to the fact that users know in advance. how much hot water they have heated, and, accordingly, they can optimally use hot water. buiners true have their own characteristics for the whole family, maybe there is not enough accumulated. and if there are a lot of people, it’s better to buy a big tank. and

the network is full of horror stories that they explode, and we checked how great the danger is in practice. there is an electric storage boiler with a capacity of 80 liters and a device of this volume in 2018 was enough to turn an apartment in the moscow region to blame for everything. as reported, then the negligent treatment of the owners became in the press. they didn't monitor the temperature sensor, so the boiler boiled and exploded. but how often is this a breakdown or rather an exception to the rule, let's try find out with the help of an electronics engineer sergei shishkin and a pyrotechnics gunsmith from the mosfilm film concern evgeny shulenin. the conditions under which the threat of an explosion really arises is when the water does not just heat up and turns into a park , a very high pressure is necessary, at least 16 atmospheres,

and in order for the valves installed by the manufacturer not to work, the explosion must be very unlucky. it is possible only with a confluence, but the emergency valve does not work, the special cut-off thermostat does not work and the thermostat itself is covered, which is set here our temperature sensors usually do not allow the steam inside the boiler to heat up to a critical temperature, but they can eventually fail from the valve, which is responsible for relieving excess pressure, often the users themselves get rid of it. it e starts to flow even during normal operation of the water heater, it either drips or there is a little bit of a pod in some jar, yes, and it bothers you, removes the jar, removes this valve and that's it. and then we are waiting for sergey and eugene for our experience violated all the instructions by removing the protection that the manufacturer installed at the factory in theory the boiler should heat up until it explodes, we filled it

halfway, so there was plenty of space for steam, but even after several hours of waiting for the explosion. it did not happen that he would give off heat to the environment and the pressure would constantly cool down, but he would withstand even with the protection removed , even with the protection removed, it was not in vain that the manufacturers tried so hard to protect and it was not in vain that we called evgeny here with his magical devices. so can we start? we they asked the pyrotechnician evgeny to blow up the charge that he put in the lid for beauty, but it was not in vain that the entire film crew was freezing all day. eugene you're ready ready three two

one fire. the explosion turned out to be comic and the ladies' experts confirmed that if you intentionally do not interfere with the design, the probability of such an outcome is minimal, but here's another question. can’t microorganisms start up inside on the internet, they scare them with e. coli and staphylococcus aureus, which breed in tanks with warm water. in the house of producer nikolai vaseykin, a large three-hundred-liter the accumulator is heated from the heating system in the summer, when problems begin in the water in the circuit far from boiling water, if you reduce the heating, accordingly , the water temperature decreases in more water. in summer, it turns out to be much cooler than in winter and, with very unpleasant consequences, a characteristic smell appears that is somewhat reminiscent of rotten eggs. water from the boiler, we handed over for analysis to the laboratory,

she found in a small amount of caliform bacteria, these include e. coli, as well as twice the excess concentration of iron, probably, the walls of the tank are poorly made, this cannot be. e, a threat to human health, that is, even if it gets into the mouth, if you do not drink such water, it may not be dangerous, but nevertheless, it will probably not be aesthetically pleasing to have orange stripes after contact with such water of any plumbing most modern hard drives have acute problems with bacteria. in fact. no heating occurs to such temperatures that little, who survives, some advanced models even have thermal sanitation functions when the water almost boils, in addition, they can adapt to the user , save electricity, control from the phone, our water heater gets to know the user's habits. that is, at what time do you turn on the water. how much you? they used it, that is, it further

adapts to your water heating schedule and the water is already heated at this time, respectively, due to this, again , savings occur. in general, different types water heaters. well, each in its own way , flowing allows you to save space and time of water. just enough for everyone. but the accumulative one reduces the requirement for the power supply, does not knock out traffic jams and gives the best pressure when choosing, you need to focus on your own comfort and the possibilities of the apartment, and then you can completely forget about the water from the kettle during the weeks that come out, loofah, silicone antibacterial impregnation. whether innovations save bacteria in dishwashing sponges , it is safer for the body. we gave them a test and checked everything in laboratories. miracle goods mosquito net will replace a new device, true or not, there is no street, as well as the most amazing

scientists from australia tested the ability of popular plants to neutralize the so-called big four dangerous and even carcinogenic common pollutants. it is benzene-to-uol-ethylbenzene and xylene in just 8 hours. greens have reduced the concentrations of these substances to 20% of the original , the researchers call for planting more plants not only in homes, but also in public buildings, especially those located near busy streets and roads. recently , american scientists advised from time to time to put a dishwashing sponge in the microwave to disinfect because bacteria multiply rapidly in a humid environment, is it really worth doing this? maybe it’s better to buy a sponge from some alternative silicone loofah material, where a microbe , it seems, is not so comfortable a sponge for washing dishes,

it’s dirtier than a toilet bowl, there are 200,000 times more bacteria on it than in a toilet to this conclusion experts have just arrived. rospotrebnadzor sponge. they advise to change at least once a week, otherwise there is a risk of catching an intestinal infection, but norwegian scientists conducted similar studies in ten european countries and found that even dangerous salmonella survives on sponges. we ourselves conducted a similar test a few years ago, we collected old sponges from the inhabitants of one of the moscow high-rise buildings and sent them to the laboratory, experts found a whole zoo of microbes in them. this was a big discovery for us, because in this group we also found pseudomonos aeroginosis. this is a pseudomonas aeruginosa. this is a bacterium that causes rotting of products and, accordingly, we also multiply on our sponge, we found the bacterium staphylococcus saureus. we found bacteria, again a group of

escherichia coli, we found bacteria, sherichia. kolya found a bacterium of the genus salmonella. what to do at the university of michigan found that a minute in the microwave kills 99.9% of bacteria, even according to scientists , you can wash a sponge in the dishwasher or soak in bleach. it is debatable, if you then rinse poorly, you can get poisoned or harm the skin of the hands, another solution was proposed by the american aaron kraus, who ended up making good money wearing it. when we started , we earned only $ 100,000 in retail sales, and now our revenue is $ 141 million, what this sponge is made of is a company secret, but aaron shows how she works in cold water, the porous emoticon seems to become stiff and you can scrape burnt ones, but in warm

water it softens to make it easier to wash, but the main thing is that the developer promises in an hour the sponge dries completely, so it doesn’t smell up to 8 weeks we can not buy this, but maybe there is an alternative. on the internet, electric trains in the markets sell and advertise a variety of samples of nano-sponges, melamine and special highly abrasive which we have not experienced, but unfortunately we have not found a universal sponge, melamine, which has a whole army of fans with strong pollution, and failed. it seems to me that the tougher samples of the new generation abrasive and the nano-cup with a surface almost like sandpaper, the manufacturer promised that both would not scratch the dishes. and if the first saved only before powerful pollution, then the second removed carbon deposits along

with paint where there was not very strong pollution. everything was wiped off, but these strong powerful old stains. they still do not lend themselves obviously in the economy you need to have different sponges, but are there any that will not be used. to actively breed bacteria, we conducted an experiment and collected four samples with loud promises. the first sponge made of foam rubber with antimicrobial impregnation 300 rubles. for 10 pieces, the seller promises that it will last five times longer than the usual second from a german manufacturer of silicone, on which, as the advertisement assures bacteria will not multiply, costs almost 1,000 rubles. another cup. everyone knows the foam rubber 103 rubles. for packaging, we take it for comparison and the fourth sample. natural loofah. we bought it on the advice of an eco-blogger and mother of three children, svetlana kovalevskaya, the price is 4014

rubles. for five pieces. it is safer, and for the body, because the foam rubber sponges have more bacteria, and different ones, than sponges made of natural material. loofah. this southern garden. herbaceous liana - the fruits of some of its species are so fibrous that they are used to make washcloths in the kitchen. svetlana uses two sponges from loofah and healing and washes them in the car. as a result, each sponge is used for about 3 months. at the same time, as she says, we will also check in practice by reducing the consumption of plastic. how good, loofah and others for the experiment. we need to dirty more dishes and make it beautiful. chef anton salnikov will help for the miracle of technology team, he will hold a master class on cooking summer soup beetroot, you know? what is the main problem with beetroot is that when you cook it, everything

around takes on this pink tint, the hands of the dishes, god forbid, some wooden surfaces. yes, i agree, this is scary, probably, housewives often, under the strict guidance of the chef, my colleagues prepared soup and ku. hny done properly. any vocational training at home, of course, it kills the capital kitchen, that is, walls and utensils and that’s it, because today we have cooked quite a bit. see already. how much dirt is left. and if , god forbid, it would be fried, that would be all. we have a sheikalo, everywhere, everything is fat, some kind of life hacks. yes, they are ready at home. it's time to wash the dishes. vasilisa took a natural loofah sponge, lenya took a silicone one, dasha, the one with antibacterial impregnation, and lisa got the usual foam rubber. let's get to work. it feels like i came to

the dacha more than to wash, i found some kind of haystack. from one soup so many problems in general. everything was washed away, it does not foam even more than everyone else had to tinker, leni is silicone. sponge i didn’t want to foam, i strove to slip out of my hands, and vegetable scraps got stuck in the villi. she doesn’t lather at all with lisa, the test with a regular foam rubber sample passed without surprises , but by the end of the wash, dasha’s sponges with

antibacterial coating began to fly off particles of the abrasive part, which is the most valuable in my opinion, into sponges, and it is literally erased. here, on a regular board, the sponge itself is also very unreliable and will save this copy. only explicit bright antibacterial effect. well, here, uh, i'm powerless, you need to find out in the laboratory, so we will make all the samples, rinse thoroughly and put them wet in bags with airtight fasteners. they will lie there for 3 days, and then the specialists in the laboratory will make liabilities on the microflora that the chef has no doubts that the microbes will start. he says that in serious kitchens the dishes are washed either in machines or with brushes so as not to poison the guests. in france, for example, sponges are banned in professional kitchens right here in general from the word completely into sponges. this, i think, is a time bomb, as anton turned out to

be right in the laboratory, bacteria were found on everyone sponges. it turned out that the maximum microbial contamination with us, uh, turned out to be on a sponge made of uh, natural materials, then, in descending order, it comes with a sponge made of silicone materials. uh, then comes the pharaoh sponge. well, in last place we have sponge with these huge impregnations, but the difference is not very big, according to the expert. any cup can be quite safe if it is thoroughly rinsed after washing the dishes , remove food and fat residues, store in a dry place and change once a week, well, the naturalness of the materials, alas, is nothing guarantees luffa will be dirtier than the toilet in the same way. if you keep it wet and do not throw it away in time. this is a miracle of technology, see the final of the program. rubric miracle goods

with glucometers, and hypertensive patients will certainly be grateful to engineers from the usa who created a spring clip that is worn on a smartphone. she squeezes her finger and the application analyzes through the phone’s camera how the pattern of blood vessels changes and calculates the value of systolic and diastolic pressure, which is especially nice in this development. so this is its cost, as the authors report in mass production. each clip will cost, no more. 10 cents now time is a miracle of goods, this section is devoted to devices and services, advertising that promises real miracles, so that it’s not true . and what we don’t really find out with all scientific certainty, mosquito nets on windows are a good thing, but sometimes they are torn or blown away by the wind, another solution is offered by the manufacturer. here is such an

unusually shaped fumigator. for 1.600 rub. hanging himself. it works on a door or window, as the advertisement promises for 100 days , there are no start buttons, connect to electricity. no need to have a circle with months as a clue, so as not to forget, when you started using insecticides and repellents inside it, which evaporate and do not let mosquitoes in, and andrey once already tested the anti mosquito lamp for the miracle of technology, then it did not bring results, time passed, and the problem with mosquitoes in the summer cottage left evgenia hung the fumigator on the window, where there is no mosquito net. let's see. will the protection come back a little later. as the manufacturer writes , the full effect is achieved in 3 days, in general, the declared active substance

peretrin has been known since the end of the 17th century, when it was noticed that some plants from the peretrum genus, for example, dalmatian, chamomile, are capable of killing insects, causing paralysis very quickly, because. these are nervous patriotic poisons, they affect special areas that bind very quickly, the active substance is isolated and actively used for animals and humans. it is harmless if the maximum permissible concentration is not exceeded and there is no individual intolerance. we asked an expert from them disinfectology to inspect the device inside a grid impregnated with chemicals and nothing else questions arose about the principle of operation, especially intensive without heating. this device must be tested in different ways,

including an experienced traveler in nature. lori ezhikova works as a hiking instructor in different parts of the country. we found her on a three-day kayaking trip in the moscow region , where during the parking lot the participants were haunted by hungry mosquitoes. in the evening, lori opened the package with a new fumigator and hung it on the tent, according to her, insects, it seems they were not at all afraid of the device, and they were able to have breakfast in peace, and the people of no this morning we came to our camp for a fire. and there were mosquitoes. we hanged the hooligan, but, unfortunately, they flew near him, so it is not clear whether he works or not, the miracle did not happen. and what is there at the dacha of evgenia and her husband? andrew it seems their rest is not disturbed. we don’t have a single insect for a week of mosquitoes in the room, there are mosquitoes on the street, there are

in the house, apparently, in the open air , peretrine vapors quickly disperse and do not have time indicate the impact on mosquitoes, and indoors everything works as it should. let's try to check this in a special sealed chamber of the institute of disinfectology, hang the device on a fan. it will create a draft effect and slightly speed up the process of spreading the active substance. after a couple of days we do an air analysis. the results showed that after two days of continuous operation of the fumigator based on epermethrins, active ingredients. it was not found in the air the expert explains the rins quickly lose their properties, bought by us the fumigator was produced in 2019. there is a possibility that the substance has weathered in 4 years, we contacted the seller to find out about the possibility of replacing the fumigator with fresher ones. no, it's one party. and we

got it this year. that's it, there is a feeling that the error yes, because it is unlikely that they have been lying for so many years, perhaps it was a mistake that he even got on the shelves of our stores, all the description on the box is in chinese. and it shouldn’t be like this, according to the rules, all these goals that are registered must have instructions or labels in russian. this is a prerequisite for registration at their dachas, most likely just lucky mosquitoes. for some reason, they themselves did not fly into the window, all other tests showed both the absence of both the effect and the active substance itself, reviews on the network. also ambiguous users, just like we do not understand, is there a result, by the way, the device itself for 1,600 rubles. the disposable cartridge cannot be replaced separately. it is not for sale, and they offer to buy a fumigator one for

each unprotected mesh. and the window, is it worth it we don't think there will be a miracle. and now , what message from the news feed about science and technology impressed me the most this week. the first place on our hit parade to capture the titanic with an unprecedented degree of detail was possible thanks to new technologies, us specialists for the first time carried out full-size 3d scanning using special devices that spent 200 hours. we took 700,000 pictures under water and eventually created a three-dimensional copy of a ship lying on the bottom of the atlantic at a depth of 3,800 m. we managed to capture not only separately, located bow and stern, but also an 8 m² debris field between them, and even found a real treasure, lost in a crash, a necklace without a tooth
