AIR POLLUTION CONTROLLED BY ROBOTS

-
Air Pollution can be defined as anything that contaminates the air to an extent that makes the air dangerous to breathe.
Air pollution happens when pollutants are carelessly discharged into the air. In other words, air pollution indicates the existence of impure, unsafe, and hazardous substances in the air.The impact of air pollution on human health includes impairment of health, respiratory problems,allergies, etc. Further, air pollution greatly impacts ecological diversity and environmental,sustainability.We all should become free from pollution.             
  1. The forest cover should be protected. Adequate forest cover is essential for maintaining the quality of air. Trees absorbs carbon-dioxide (CO2) and releases oxygen (O2).
  2. Green belts should be created. Such areas should be developed around densely populated cities. There should be strict restriction for establishment of large buildings and industries along the Green belt areas.
  3. Automobile engines should be redesigned in such a way that their emissions cause minimum pollution. Old automobile engines should be replaced by new ones. People should be encouraged to share the vehicle, and to avoid vehicles for short distances.
  4. Use of railway steam engine should be stopped. The burning of combustible materials such as coal produces poisonous gases that are released into the air. Electric engines should be used instead of steam or diesel engines.
  5. Industrial areas should be located at a safe distance from the residential areas.
  6. Newly designed smoke free furnaces should be used.
  7. Forest fires should be checked. Adequate preventive measures should be adopted to protect the forests.
  8. In industries there should be the arrangement for pollution control.
  9. Cheap devices for controlling air pollution should be developed.
  10. Air pollution can be checked only through the joint efforts of the government, non‑government organizations and the general public.
  11. These “Parasitic” Robots Are Designed To Suck Pollution From City Air

  12. A concept for urban drones that perch on a city billboard and harness heat from the neon and pollution from the air to create a more sustainable fuel.




    The CO2 also helps boost the growth of plants on the robots’ wings, so the robots can double as miniature farms. “The plants and robot work as a hybrid, because the main goal is to reduce CO2,” says Michal Jurgielewicz, a Beijing-based architect who is part of the design collective NAS-DRA.
    “The plants are planted and harvested by humans using hydroponic farming,” he explains. “We’re aware that urban conditions can be harsh and growing the plants for food can be difficult. It should be adjusted to the place and conditions, so using sensors, one can modify how plants should be grown.”
  13. The system would collect organic waste from the plants to create biogas, while the extra CO2 would be used to create methane. Some of the power from these fuels can run the robots themselves, making the system self-sufficient.

  14. The neon billboards that line Hong Kong streets may eventually do more than just sell products. In a new project, a group of designers hopes to use the signs–along with a fleet of drones–to suck CO2 out of city air.NAt night, when the billboards light up, the robots would attach to them, using the heat from the neon in the next step of the process. Heating up the polymer to a certain temperature releases the CO2, which can be collected and used in energy production.

  15. uring the day, the drones (or, as the designers call them, “parasitic robots”) would perch on billboards. Coated in a polymer known for its carbon-sucking powers, the robots spread their wings and collect pollution as long as the sun is up.

    Highlights

    •
    Reduction of the atmospheric pollutant emissions without loss of autonomy.
    •
    Analysis of the exhaust gases in precision agriculture using robotic tractors.
    •
    Hybrid energy system in robotic tractors for weed and pest control.
    •
    System based on H2 fuel cell, batteries, PV energy and internal combustion engine.
    •
    Results obtained experimentally using real agricultural machines.
    A hybrid energy system used in robotic tractors for precision weed and pest control in agriculture is evaluated and its exhaust emissions compared with the use of an internal combustion engine as a single power source. The agricultural implements require power for hydraulic pumps and fans which, initially, was provided by a power take-off system (PTO), wasting a lot of energy. The objectives of this work were to design and assess a hybrid energy system including the removal of the alternators from the tractor and the modification of the agricultural implements to replace the PTO power with electric power, using small pumps and small fans. These changes improved energy use and reduced the atmospheric pollution emission from the internal combustion engine. The hybrid energy system used the original combustion engine of the tractor in combination with a new electrical energy system, which consisted of a hydrogen fuel cell. An analysis of the exhaust gases using the internal combustion engine as the single power source and using the hybrid energy system was carried out to compare the results obtained. The results showed a reduction in emissions of almost 50% for the best case.
  18. POLLUTION-EATING ROBOTS COULD HELP PROTECT THE PLANET
  19. “Sometimes, tankers flush their oil tanks into the sea, so oil is released into the sea that way,” said roboticist Jonathan Rossiter, host of a TED Talkthat discussed the potential these robots may have. “Wouldn’t it be nice if we could treat that in some way using robots that could eat the pollution the oil fields have produced? So that’s what we do – we make robots that will eat pollution
  20.  ” which is then digested and converted to energy that powers the propulsion and paddles through the boat’s motor. According to Rossiter, the robot can operate continuously for months,generating more energy than it consumes.Researchers at the University of Bristol may have engineered a new way to clean up our planet’s waterways – with a swimming machine called “Row-bot,” which digests pollution and turns it into electricity for fuel.

Absorbing Advance About Alcohol Achieved in 2017

Alcohol Makes Rats Turn To Cocaine The most common research involving alcohol typically concerns its effect on humans. One area of particular interest is its addictiveness and if alcohol will leave you more vulnerable to drug use. A study from 2017 supported this idea by showing that drunk rats like  cocaine . During the experiment, rats were given alcohol for ten days before being offered cocaine. Afterward, the animals proceeded to consume the drug despite being administered an electrical shock each time they did so. Overall, these rats attempted to “score” by pressing a lever an average of 58 times, while a control group which was given water only did it 18 times. This kind of compulsive behavior is found in about a quarter of human cocaine users. While it is common for these people’s cocaine addiction to be preceded by other  substance abuse , the biological mechanism which prompts certain drugs to act as “gateways” is still poorly understood. This study suggests ...

CONTACTS MEASURING GLUCOSE

Jin Shang, a professor of biochemical engineering at the University of Western Ontario, has invented a contact lens that changes color when sugar levels change in the blood. Those suffering from diabetes need to draw blood to check sugar levels. Nanoparticles implanted in contact lenses interact with glucose molecules in tears. This interaction changes the color of the lens to indicate varying sugar levels. This new medical invention could eliminate the need to draw blood to monitor glucose.

Astrology vs Astronomy: What’s the Difference?

Though the practices of astrology and astronomy have common roots, there is an important distinction in astrology vs astronomy today. Astronomy is the study of the universe and its contents outside of Earth’s atmosphere. Astronomers examine the positions, motions, and properties of celestial objects. Astrology attempts to study how those positions, motions, and properties affect people and events on Earth. For several millennia, the desire to improve astrological predictions was one of the main motivations for astronomical observations and theories. Andreas Cellarius's illustration of the Ptolemaic System (17th century), which shows the solar system and signs of the zodiac with the Earth at the center. J. van Loon, National Library of Australia Astrology vs Astronomy Astrology continued to be part of mainstream science until the late 1600s, when Isaac Newton demonstrated some of the physical processes by which celestial bodies affect each other. In doing so, he showed that the s...
