We know that research and invention are two important aspects of development, without which it is impossible for any country to move forward on the path of development. He was very active in inventions and discoveries and was instrumental in expanding the canvas of science and technology worldwide. This year too, the flight of knowledge and wisdom continued to like many years ago and many flags of new inventions, discoveries and investigations were hoisted in the field of science and technology.
Discovered new ways to generate electricity, created robots for various tasks. Drones and automatic boats were developed, a new record was set by sending 143 satellites into a rocket and much more came to light. will be done.
Self heating lunch box | Heating Box
This year, a Dutch engineer has developed a lunch box with a stove and microwave installed. It has been dubbed the “heat box”. It charges via USB. After charging it, you say Can also be taken. Just switch on the food before eating, after which the steam inside warms up the food well. All you have to do is pour in 20 ml of water which goes into the steel pot inside. The food can be sealed by placing a lid on it and thus the hot steam passing through every part of the food heats it instantly. The internal valves in the lunch box maintain the vapour pressure and thus the pressure inside the vessel does not rise alarmingly. With the app, the temperature of the lunch box can also be increased or decreased.
Ocean floor research boat
The American company has developed a drone boat in 2021 that automatically maps the ocean floor moving from solar energy and also collects valuable data of the marine environment. Its length is 72 feet. It is primarily powered by wind, but all electrical appliances and guides are powered by solar energy. It is also equipped with the world’s most advanced marine, marine and meteorological instruments and sensors.
It can be controlled and it can run automatically but it can work on a full-year mission. Biomass in the water and the measurement of dissolved carbon in the ocean are among its primary objectives. ۔ The DNA sensors in the ark will work in a metagenomic way by extracting DNA from the water.
Record for sending 143 satellites in one rocket
In 2021, a company called SpaceX set a record of sending 143 satellites into orbit with a single rocket. Under the Transporter One mission, the Falcon Nine rocket booster flew over the Cape Canaveral space base, with satellites mounted on top of it, similar to items placed in supermarket compartments. The company has sent these satellites under the Small Set Ride Share program.
Their goal is to launch a slightly limited but low-cost satellite into space in a single leap. This makes it easier to work on small satellite projects. The payload includes 133 satellites belonging to the US government and private companies, including some cube sets and microsatellites, but the ten largest satellites belong to the Starlink program, which will orbit the polar orbit and make the Internet more global. The facility will be provided.
The world’s first laptop with seven screens
The British company Expanscape has built a unique laptop in the world this year, which has not one, not two but seven display screens that can be used for very serious tasks. This computer has been dubbed “Expanscape Aurora Seven”. It is designed specifically for cybersecurity, security camera footage, IT experts, designers, stock exchanges and online trading experts. Can be annoying
It is the world’s first laptop to be fitted with seven displays of various sizes. It has four large 17.3-inch monitors, two of which are landscape and two are portrait style. They all have four screen resolutions. There are three more seven-inch displays. Its robust structure handles all displays and looks like a laptop transformer. It has an Intel Intel Nine 9900 processor, 64GB DDR4 2666 memory and a hard disk capacity of two terabytes. It has separate batteries for computers and displays that last up to two hours.
Plastic Pollution Location App
Plast pollution is a major problem. To address this, the Norwegian University of Science and Technology (NTNU) this year developed an app that can tell where the garbage came from. Use this app Ordinary people walking on the beach can also take a picture of the garbage and send it to the app’s database with its GPS (coordinates).
As soon as you take a picture of an object made of plastic, the app identifies the object from the database. She then tries to find out where the garbage came from with the help of water waves, meteorological conditions and ocean currents. In this way, a careful estimate can be made as to which sea route it has reached to the shore. Garbage sites can also be cleaned through this app.
A kite made by submerging in water
This year, scientists tested a kite-like swimmer’s device that will generate electricity on the waves of the ocean waves. The brain is a kite made of polymer composite foam, which resembles a very similar manta ray fish. The kite is attached to a string and its front end is mounted like a peg on the seafloor or the part of the river where strong waves are forming.
The end of the wire is connected to an electric motor and a generator. Its angle in the water will be such that the full force of the flow falls on it. This way the wire opens and rotates the generator. This generator generates electricity and stores it in a battery or transmits it directly to the central grid system. This is how it goes. Theoretically, a kite can generate 20 megawatts of electricity.
Scientists have developed a capsule to take humans into space in 2021, on which you can travel the entire space for a ticket. This beautiful balloon has been dubbed the “spaceship Neptune” under a planet in the solar system. Light gas.
The passenger space balloon is similar in size but much larger in size than the helium-filled balloons used for research. Beneath the balloon is a long, strong wire with a passenger capsule attached to it. It has a seating capacity of eight passengers and one pilot. The capsule is filled with air at approximately the same pressure as the ground pressure to protect passengers and create an earth-like atmosphere.
Underwater “submarine drone”
This year, a Beijing-based robotics company has developed an underwater reconnaissance drone. It looks like a normal fish. This drone is not only like a fish in appearance but also its swimming style is exactly like a fish. The eyes of this “submarine drone” are equipped with spy cameras that are capable of seeing far inside the sea.
Not only that but its skin is also fitted with a variety of sensors that keep it constantly aware of various other features, including seawater temperature. This submarine drone can float in water for up to eight hours on a single charge. It is designed for researchers in marine science and marine life, but can also be used for undercover surveillance if needed, and will be useful in the future.
Wrist strap that converts body heat into electricity
This year, Professor Chian Zheng and colleagues at the Harbin Institute of Technology in China have invented a wrist strap that can illuminate an LED from body heat. This wrist strap is a thermoelectric generator (TEG). Generates electricity by working under the principle. In the future, this technology will provide power to smartwatches and light wearable devices, thus eliminating the need for batteries.
Experts have made this strip of magnesium and bismuth from polyurethane and made all the electrodes flexible. In this way, the whole strap is soft and flexible and can be worn by twisting on the human wrist. The principle of TEG is very simple ie such devices generate electric current by changing the temperature in two places. Similarly, the strip generates electricity from the difference between body temperature and room temperature. This strip generates 20 microwatts of electricity per square centimetre in optimal condition. This amount of electricity is enough to light an LED.
“Microflyer” drone-like a grain of sugar
Engineers at Northwestern University in the United States have invented the world’s shortest drone in 2021, which is as small as a grain of sugar and can be blown by the force of the wind. Less so when its three wings help it fly. In the middle are all the devices, including the microchip, that help it store energy and learn about the environment. This micro flier drone has no motor installed to rotate the tiny mini petals, but it flies in the air like seeds scattered far and wide in the air.
This technology will serve us for a variety of purposes, from commonly used devices to medical diagnostics and environmental surveillance. Are transformed into substances. It has just been built experimentally. A large number of micro fliers for environmental research will be loaded into a plane or drone and taken to a great height and then released into the air. These microfibers will spread far and wide with the wind. At the same time, it will collect data and broadcast it to the data collection unit.
Power cards from Five G system
This year, experts at Georgia have developed a card that generates electricity with the help of Five G. It can generate electricity directly from the radiation emitted from the Five G tower. This card draws 6 microwatts of electricity at a distance of 180 meters or 600 feet from the Five G Tower. It is the world’s first 3D, a card-like rectifying antenna that can draw electricity from the Fiji Tower. Theoretically, wireless communication systems generate a lot of energy.
But more energy requires larger rectifying antennas, then the antennas also have to be turned in the direction from which the radiation is emitted. Or can be used in smart agriculture, however, to solve many problems, a kind of part has been inserted right in the middle of the card which is called “Routman Lens”.
Along with the root man lens, the card is made so flexible that it can be twisted and the entire circuit can be printed from the printer. Although the card generates a small amount of electricity, it can be used to operate small sensors, the Internet of Things (IoT) and other small devices. Experts hope that their invention will lead to a revolutionary change in wireless technology and energy.
This year, experts from the three countries have jointly designed a state-of-the-art sailing boat that can fly at high speed, almost flying over water. The boat has been dubbed the “Persico F70 Hyperboat”. Designed in partnership with Persico Marine, Corkcake Design Partners and Penn Farina Natika, it is 70 feet long. It has long sails that can be opened and closed if needed.
In order to make the boat as light and strong as possible, it has made full use of a substance called carbon composite. When the sails (foils) are opened, it will be in “full flight mode” on the wind blowing at a speed of only 10 knots (18.5 km / h). Will be touching, meaning it will feel like floating on water.
Its width is much less than its length but still, its inner part is very spacious and comfortable. The Persico F70 hyper boat will also be fitted with an electric engine, but will only be used when absolutely necessary. In this sailing boat, the beauty of the design, the durability of the structure and the laws of hydrodynamics have been summed up simultaneously.
The smallest power generating turbine
In 2021, scientists have developed the world’s smallest wind turbine to reduce the power crisis, which weighs just three pounds and can generate electricity by spinning at 8 to 28 miles per hour. It takes two to three minutes to set up and open. This wind turbine has been dubbed “Shine” and can also be called an environmentally friendly and efficient air charger.
Whether you’re hiking in the mountains, on the beach or in a field, Shine can generate electricity from even the slightest gust of wind, which is enough for your needs. Overall, it is a 40-watt turbine with a powerful 12,000 mAh battery that can power smartphones, cameras, lights and other small devices. Therefore, this turbine is very useful for outdoor travellers, support staff or photographers.
What makes it special is that it makes no noise and produces only 50 decibels of sound. Its special design can withstand all kinds of climatic effects. Because of this, Shine can be run year after year. Even if the temperature in a place is 40 degrees Celsius, its electrical system and design remain intact. Despite its small design, it generates electricity efficiently and can charge objects via USB.
