How big is the travel suitcase with "vacuum suitcase"

Invention is the starting point of technology and production activities. With the invention and application of stone tools and artificial fire, the history of human material production and social life began. The development of social history is inseparable from development and creation. In order to make our human future better, scientists all over the world are committed to new inventions that change human life. These new inventions make our life more convenient and interesting.

Vacuum suitcase

Tourism is the favorite of modern people. In order to live comfortably outside, everyone wants to bring more clothes. However, it seems that no matter how big the suitcase is, it can't hold what you want to take. To this end, British scientists who love to travel are developing a vacuum suitcase. This vacuum suitcase is divided into three layers, and each layer is equipped with an independent air extraction device. There is also an automatic pressurization device in the vacuum suitcase, which can compress the clothes in the suitcase to a minimum. The compressed vacuum suitcase looks as big as an ordinary suitcase, but it can hold three times as big as an ordinary suitcase.

Music lullaby

As we all know, music is good for health. Now we are in a fast-paced era, with great pressure in life and high mental tension, which makes many people insomnia. Therefore, scientists in China are developing a musical lullaby. When you have difficulty falling asleep, just listen to a music lullaby to ensure that you can fall asleep safely within 5 minutes.

Cold killer

Cold is a common disease, and no one can keep a cold all his life. According to the statistics of scientists, the annual cost of treating colds all over the world is several trillion dollars. American scientists are developing a cold killer, which can induce cells invaded by viruses to "commit suicide", so as to achieve the goal of not catching a cold for life.

Interactive magic mirror

According to British scientists, an interactive mirror is a kind of mirror with microcomputer software. The mirror looks like an ordinary mirror, but it has a special function that ordinary mirrors don't have, that is, the mirror can recognize you and interact with you. As long as you pick up the magic mirror, it can not only reflect your appearance, but also see your health. If your body is in a sub-health state, the magic mirror will remind you to strengthen physical exercise and improve your diet. If you have a disease, the magic mirror can diagnose it as accurately as a doctor and urge you to go to the hospital as soon as possible. In addition, the magic mirror can also provide you with news and tell you the weather. This kind of interactive magic mirror can be called universal magic mirror.

Drunk detector

Car accidents are fiercer than tigers, and the dangers of drunk driving have aroused the vigilance of the whole world. How to effectively control drunk driving? American scientists are developing a drunk detector, which can be installed on the steering wheel and ignition button to directly measure the alcohol concentration in the driver's blood. This drunk driving detector is amazing, it will automatically analyze the driver's breath and skin to determine whether it is suitable for driving. If the alcohol concentration in the blood reaches or exceeds the legal upper limit, the drunk driving detector will give a warning and control the car engine to automatically lock, so that the driver can't start the car, thus avoiding the harm of drunk driving.

Crime predictor

The lower the crime rate in a country, the higher the degree of harmony in this country. Crime is not allowed in a harmonious society, but it is better to fight crime than to prevent it. Canadian scientists are working to develop a crime predictor. With the help of a computer program that can predict crimes, as long as some people who may commit crimes are monitored, the police can know in advance where the criminals will commit crimes and then rescue them in advance, thus avoiding tragedies.

Thinking about readers

The human brain is the most complex and compact organization in the world. Russian scientists are developing a kind of mind reading. It uses a special scanning technology to imitate the thinking of the human brain, and can even translate the thinking in the human brain into language. Imagine if mind-reading can really be developed successfully, and using it to detect criminals or corrupt officials will definitely make them have nowhere to hide.

Magic drawing pen

Magic drawing pen is a pen with computer software, which uses ultrasonic and infrared technology to capture every line you draw and send the information to the receiver installed on paper. The magic drawing pen is connected to the computer through USB socket, so the drawing on paper will be automatically transferred to the computer folder.

Practical invisibility cloak

Since the popularity of Harry Potter, the invisibility cloak in the movie story has attracted the attention of audiences all over the world. To this end, American scientists have stepped up research and development while the iron is hot. According to the recent research by American scientists, this cloak looks like a thin sweater. When it is heated to 2 200 degrees Celsius, the heat it releases can bend the surrounding air and light waves, making the thin sweater invisible.

Fire extinguishing electric rod

Fire has always been the natural enemy of mankind. With the development of society, mankind has entered the era of electrification. However, frequent fires in the electrification era put forward higher requirements for our fire protection. The traditional fire extinguishing methods are all water or fire extinguishers, which destroy the original appearance of the fire scene. To this end, American scientists are developing an electric wand that can put out fires. The main component of this device is an electrode, which can form an electric field, and the electric field generates a charged particle stream to fight against the flame, thus weakening the fire and extinguishing the flame. According to scientists' experiments, as long as the electric rod is aimed at the flame, the flame at a distance of 10 ~ 30 meters will be extinguished immediately.

Clothing printer

Since ancient times, clothes have been made by tailors or workers in garment factories. However, German scientists "whimsically" developed a clothes printer. Its design principle is: use computer to design clothing patterns, and then use a large 3D printer to print out the formed pieces. Of course, this 3D printer is a large computer-controlled printer. This kind of clothing technology abandoned the tradition of using needle and thread in the original clothing industry and brought different innovations, which not only greatly improved the clothing speed, but also greatly reduced the required labor input. At the same time, the production of clothes can be more personalized.

Artificial random cloud

Artificial random clouds are clouds that can be controlled manually. The 2022 World Cup will be held in Qatar. Because the weather in Qatar is very hot, Qatar meteorological department and American scientists jointly developed an artificial random cloud. Scientists can create huge artificial clouds over the sports ground to provide shade. This cloud is an ultra-light carbon structure filled with helium, and its position is controlled by a remote-controlled solar engine.

Carpet solar panel

Solar energy is an inexhaustible green energy source on the earth. Colorado Solar Company is developing a carpet solar panel, which can be unfolded and rolled up like a carpet and can be directly integrated into building materials. If carpet solar energy can be successfully developed, it can be applied to all fields where solar energy can be applied, such as transportation machinery such as cars, trains and ships. In addition, carpet solar panels can also be installed on the roofs and walls of office buildings to fully absorb solar energy.
