10 powerful inventions in the world, amazing beyond your knowledge. First of all, there are clothes that can repair themselves, and super air conditioners that don't cost a kilowatt-hour of electricity, and the great invention of the number one can actually satisfy our dreams of being invisible at any time, can you believe it? In this issue, let's take a look at these powerful inventions. Let's go.
10th place: clothes that won't break.
Possessing the ability to heal itself, it has become the standard for many superheroes. I thought this was just the plot of the movie, but I didn't think that there was really a fabric that could not be pierced and repaired automatically in reality. Penn State University has developed a new high-tech nano-repair material, nanocuretech, which can be used to make clothes that can be perfectly repaired with a simple twist of the hand, even if two holes are pierced with a thick needle. It is reported that the inside of this material is a special grid-like surface, and when it is punctured by a foreign object, the internal structure will not be damaged, but the grid will be pushed away. When the fingers are rubbed together, the friction and heat can restructure and restore them.
Designers also added reinforcing fibers and applied a PET coating to the surface to make the material even more self-healing. Even if the fibers break, they can repair themselves with the action of the PET coating on the surface. It is understood that this fiber material can not only be stretched to 50 times the length without damage, but also can be used to conduct current. In addition, thanks to the addition of enzymes, the special coating on the surface of the fabric neutralizes toxic chemicals, making it a perfect suit. Nowadays, there are many companies that use it to make clothes and bags, do you want to have one?
9th place: Magical public toilets.
The cleaning of public toilets often varies from place to place, and without cleaning, it would be unimaginable. But a public toilet in the Netherlands is an exception, not only is it kept clean all the time, it is disinfected once it is used, and what is even more amazing is that it has no cleaning staff. What's going on? Dutch toilet system manufacturer Senitronis has developed a complete toilet system with cleaning functions over a six-year period. When it detects that the user is leaving, the toilet's fully automatic cleaning program is activated, the toilet is baptized in a sealed container with a built-in high-pressure water cannon, and then disinfected and air-dried. A high-pressure water cannon set on the surface will sweep them away.
But people have three urgencies, and when they can't hold it back, they can't wait for it to be cleaned. Don't worry, the designers have long thought of it, they have designed two toilets before and after, one of which will automatically turn around when it is cleaned, and the other toilet that has been cleaned and sanitized will accept its work. Importantly, the whole process is extremely short, and the floor cleaning takes only 20 seconds, which makes the toilet look brand new in no time. Moreover, the switches of the toilet are all infrared sensor probes, so there is no need to worry about privacy leakage. In many places such as stations with a large amount of water, the sanitary conditions of public toilets that rely on manual cleaning often need to be accommodated. If such public restrooms were to become widespread, it might improve a lot. Do you want it to be in your city?
8th place: super fierce traffic lights.
Traffic lights make our travel more orderly, and at the same time, we need to consciously abide by them to ensure safety. Inevitably, there will be some three treasures, relying on the pedestrian advantage to cross the zebra crossing. In order to solve this situation, managers have tried their best to prevent it by means such as fines for guards, but the cost is not small. So the French took a different approach and designed what is said to be the most terrifying traffic light in the world. At first glance, it is no different from an ordinary traffic light, but there will be a billboard next to it, once it detects that a pedestrian does not obey the traffic rules, it will immediately make a huge car brake sound, which directly scares people into flying, and the pedestrians around you will also be attracted to you, making you embarrassed to not move. Of course, it is not enough to rely on the next person, so that some people consciously obey the traffic rules.
The built-in camera on the bulletin board captures your panicked face and makes it public on the big screen. There will also be a note below: "Don't joke with your life, press the signal light." What's more, the captured ** will even be circulated in the subway as a public welfare promotion**. This feeling is as embarrassing as dozing off in class, being suddenly called by the teacher and drooling at the same time, and being captured and projected on the classroom projector. With such a virtual car accident sign, who else would dare to run a red light?The above super traffic light only improves our safety awareness, but the following super invention can save our lives when we actually encounter an accident, with a success rate of up to 90%.
7th place: roller guardrail.
When it comes to highway metal guardrails, they are used to protect driving safety, but they have become fatal in many car accidents. In order to avoid a recurrence of the tragedy, the South Korean company ETI has designed a new guardrail rotating bumper canister. Don't underestimate these plastic rollers, they will save countless lives. And the principle for this effect is actually very simple: rotation. Through the free rotation of the rotating cylinder, the vertical impact force is decomposed to the direction parallel to the guardrail, thereby reducing the consequences caused by traffic accidents.
The Iva and polyurethane materials it uses are also elastic, crash-proof and wear-resistant, which can avoid the rotating cylinder being smashed when impacted, and effectively protect the protective fence and the people in the car. In addition to good anti-collision and wear-resistant performance, it also has the advantages of anti-corrosion, anti-ultraviolet aging, etc., and can be used under outdoor natural conditions, with a life span of at least 10 years. It is worth mentioning that the rotating barrel also has a strong restoring force, which can quickly return to its original shape even after a severe impact. At present, the product has obtained 22 invention patents and is widely used in Germany, Japan, the United States and other countries. This device is said to reduce traffic fatalities by more than 90%.
Sixth place: Highway generators.
As we all know, renewable energy includes wind, solar, geothermal, etc., but these equipment must either be built in remote areas, or require huge investment, which is simply impossible without state support. However, on the streets of Istanbul, a strange device has appeared, which is said to produce pollution-free clean energy just by standing in the middle of the road. This weird-looking pillar is called INL, and as soon as you put it in the middle of the road, the electricity will be endless**. INL is the inspiration of two foreign guys in the vast traffic.
In the middle of the INL is a special fan blade that blows the fan blades when the car passes by with a strong wind, and the fan blades drive the built-in turbine to generate electricity. Above it, there is also a small solar panel that collects wind energy and solar energy at the same time. What's more, it also has a variety of built-in sensors that can monitor air temperature and wind speed, as well as air quality, and even monitor**. In addition to the wind from the car, natural wind can also allow it to generate electricity. As a result, this small device can be installed not only on the road, but also on the roof of a park or anywhere else you can think of. It is estimated that only 300 units will be needed to provide electricity to 20,000 homes**, which is really powerful.
5th place: air conditioner without electricity.
On a hot summer day, we can comfortably blow the cool breeze, but in Bangladesh, many residents in poor areas do not even have electricity. For them, fans and air conditioners are too luxurious, so they can only endure 45 degrees Celsius. However, an inventor named Archepol designed a low-cost, electricity-free natural air conditioner in order to save countless Bangladeshis from the scorching heat. The natural air conditioner he designed is made from used plastic bottles and cardboard, and is very easy to make. First cut the plastic bottle from the middle, then cut off the bottom surface of the bottle cap, select a thicker board, drill holes in the board according to the size of the bottle cap, and then insert the processed plastic bottle into the small hole, tighten the treated bottle cap, and finally install the bottle mouth inward and the bottle body outward on the window. So how does this air conditioner work? In fact, it is a clever borrowing of the power of nature. Everyone must have this feeling, open your mouth and blow air, and what comes out is hot air; And when you pout and blow, what blows out is a cool breeze. A plastic bottle that is processed into a funnel is like a pouting mouth, squeezing the air to turn the hot air into cold air and then blowing it into the room. According to tests, with the effect of ecological air conditioning, the room temperature can be successfully reduced by 5 to 10 degrees Celsius. Although this installation is simple, it is very popular with local residents and has become a unique local landscape.
Fourth place: vacuum wall climbing machine.
In the movie "Spider-Man", the protagonist's superpower of flying eaves and walls makes countless people envy and yearn for it. However, in reality, a vacuum wall climber designed by Utah State University in the United States can really allow people to climb a 27-meter-high wall smoothly. With it, it is no longer difficult to transform into Spider-Man. The machine looks like a hiking bag and consists of two small vacuum cleaners, plus two suction cups. When the machine is started, the air in the two suction cups is pumped out, and the suction is generated through the vacuum suction cups, which fixes the person to the vertical wall.
The battery inside the machine can work for about an hour and a half, enough to climb a wall more than 20 meters high. The original intention of this invention was that the United States hoped that soldiers could climb high walls without using any ropes, and the military provided $100,000 in funding for the university. Currently, the scope of the wall climber is limited to glass bricks and rock walls, but the military hopes that through continuous improvement, it will eventually be used on any vertical surface. If this wall climber is improved and widely available, do you want to have it?
3rd place: Amazing plaster saw.
Friends who have broken bones may have experienced that when the cast is finally removed, they will always be very worried when looking at the saw, and pray that the doctor's hand will be steady. In practice, however, plaster saws are specially designed to easily cut through hard plaster without injuring it. What's going on? Slowing down the lens by 100 times, we can see that the blade of the plaster saw does not rotate at high speed like a common saw, but swings back and forth, and the amplitude of this reciprocating swing is very small, about 3 mm. Therefore, this type of cutting will only cause damage to hard objects.
Do an experiment with a balloon, and the effect is clear at a glance. When the plaster saw encounters an insufficiently inflated balloon, the surface of the balloon has a certain tension and can swing with the knife without harm. And if there is no room for the surface of the balloon to swing, it will burst instantly. Therefore, as a soft object, our ** is very elastic, and when it comes into contact, it will drive ** to vibrate together, and the tool will not be forced, so that it will not be scratched. Gypsum, on the other hand, is harder, and when it comes into contact with a plaster saw, its surface cannot collapse and is cut off by the saw blade moving back and forth. The person who designed the plaster saw was a genius who was able to solve the problem easily and be safe.
Second place: life-saving black technology.
This is an intelligent soft robot that can be long or short, and can easily pass through gaps, called vanbot, which was invented by Stanford University. Inspired by the vines known as rock climbers in nature, the robot was designed by combining the growth and extension of the vines with the working principle of the water baby toy. When put into service, an air compressor is used to inflate the hose, and then the top of the drive is flipped from the inside to the outside to extend the crawl. It can stretch to a predetermined position at a speed of 35 kilometers per hour, and can quickly expand and harden to support 200 pounds of goods. The robot uses an air pump to inflate three independent pipes to achieve turning, simulating the principle of human muscle contraction, coupled with high-definition cameras and sensors on the head, to achieve pervasive operation. The biggest advantage is that it can provide oxygen to the trapped person through a narrow gap, and even help the trapped person get out of the trap by lifting heavy objects. Its role is especially obvious in disasters such as **, and it can also be applied to the fields of archaeology and medicine. Where else do you think this intelligent soft robot can play a role?
1st place: stealth material.
In the movie "Harry Potter", there is an invisibility cloak that makes people feel intrigued. Hyperstealth has developed a quantum stealth material that can achieve stealth effect, this paper-thin material is not expensive, and it can achieve stealth without the help of electricity or other external settings.
By superimposing countless sets of double-convex lens lenses to form a grating, the principle of light refraction to produce visual blind spots is used to produce the best effect. It's hard to find even on a thermal imager. This quantum stealth material can help soldiers evade enemy search on the battlefield, so it has received strong support from the United States and Canadian military. This material can be used in a wide range of applications and provides excellent stealth results.
