Water from atmospheric moisture
As proved by the scientists at MIT, even in the driest places on Earth, water can be obtained by extracting the moisture that rises in the atmosphere. They created a device that they successfully tested on dry air in Tempe, Arizona. It has also been published in the journal Nature Communications.
The design of the device is based on modern materials called organometallic networks. Thanks to this, it is able to draw drinking water from even the driest desert air. Also when the humidity is below 10 percent. The device can be a real breakthrough and a boon for the inhabitants of the driest places on Earth.
NASA wants to send a helicopter to Mars
In two years, another NASA mission to Mars is planned. In 2020, the Atlas V rocket is to be launched, which will provide a new Mars rover, the successor to the Curiosity. The landing is scheduled for February 2021. In addition to the standard operation of the Red Planet, the Mars 2020 rover will be tasked with delivering the first-ever helicopter. Its main task is to take aerial photos of the surface, which will allow us to get to know the fourth planet from the Sun even better.
A city bench that ... cleans the air
Green City Solutions, a German technology start-up, has installed its latest invention in London. The bench made in the CityTree structure is to perform three basic functions: it was an element of the public infrastructure, to act as an air-purifying filter, and to monitor the condition of the environment.
The dirt removal function was achieved thanks to the combination of mosses and lichens used. These plants naturally contribute to the absorption of pollen from the air, thus improving its quality. Solar panels have also been installed to meet the energy needs of the bench. If it turns out in practice that CityTree fulfills its functions, it can be a real revolution on the way to fight global warming.
Technology news. A breakthrough in recycling plastics?
Scientists studying the structure of the bacteria found in a landfill in Japan were shocked. They subjected it to an intense beam of X-rays, and as it turned out - the bacteria began to decompose not only vegetation, but also plastic packaging.
The research was conducted by prof. Jon McGeehan of the University of Portsmouth. In his opinion, this discovery may be a breakthrough in the context of the collapse of the growing problem of littering the planet. Work is currently underway to use the enzyme produced by these bacteria to obtain ingredients from which plastic packaging was originally made.
