Air pollution and garbage harm the environment in big cities. In response, many cities have developed technologies that provide new ways to keep the air clean.
A robot that gets rid of garbage
Waste management is not the most exciting household chore, but if a Wall-E style robot could perform the task? It would undoubtedly change the experience.
Peccioli, Italy, has introduced an innovative way to maintain clean streets. According to a report from MIT Technology Review, Dustcart is a robot that can respond to calls from people who live in the town.
People can simply use their mobile phone to communicate with the robot. When Dustcart arrives at a person’s home, a text message displays a code that should be entered into the robot’s screen.
The robot allows people to select the type of waste they plan to deposit on its screen and then put it inside. Dustcart then removes the waste and recycles it. The robot is equipped with sensors that prevent collisions, a C02 meter and other elements that measure the level of contamination in the air.
A drone that eliminates pollution
In cities like Beijing, China, pollution has become a real danger for inhabitants. In order to ease this problem, a drone-based technology that can freeze the contaminants that cause pollution and send them to the ground was created. The project is expected to be used in areas close to airports running a glider, which would reduce their production in comparison with other prototypes.
A vacuum that eliminates contaminated air
Beijing continues to promote the development of technology to reduce its air pollution problem. Dutch inventor Daan Roosegaarde has proposed a solution: a vacuum that removes smog from the air. The vacuum carries out this task using electromagnetic fields that attract the particles that produce pollution and deflects them to the ground.
Roosegaarde explained: «The system is similar to the principle that is applied when a balloon charged with static attracts a person’s hair.» The project will be implemented towards the end of this year in public parks in Beijing.
