Solar Desalination System

07.04.2024

Lack of fresh water is one of the most pressing problems facing a significant part of the world's population. In search of effective and environmentally friendly methods to solve this problem, researchers from various educational and scientific institutions are introducing innovative technologies based on the use of solar energy.

Researchers from King's College London, the Massachusetts Institute of Technology and the Helmhotz Institute for Renewable Energy Systems have developed an innovative system that uses solar energy to desalinate salty groundwater. This promises to be a cheaper and more effective solution compared to traditional methods.

About 40% of the world's population faces fresh water shortages, and 4 billion people experience acute water shortages for at least a month a year, according to the UN.

Desalination technology works like this: Specialized membranes are used to channel salt ions, and then the salt water is separated from the fresh, potable water.

The team also developed a way to flexibly adjust the speed and voltage of the system, allowing it to adapt to different lighting conditions.

Initial trials were conducted in India, where access to clean water is a particularly acute problem. Successful results showed that the system is capable of providing up to 10 cubic meters of fresh water per day, which is enough to support the livelihoods of thousands of people.

This is not only an environmentally friendly solution, but also cost-effective. By using solar energy and inexpensive components, the system offers access to potable water at a lower cost than traditional methods.

An advanced solar-powered desalination system opens new horizons in solving the problem of access to fresh water. Its efficiency and environmental friendliness make it an important step towards ensuring sustainable access to water resources for all segments of the population.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Unmanned passenger Boeing 17.06.2017

Boeing has begun research into the possibility of building commercial passenger drones that will use artificial intelligence as an autopilot system to make decisions during flight.

"The building blocks for building the technology are already in place," said Mike Sinnett, former chief project engineer for the Boeing 787 Dreamliner and current Boeing vice president of future technology innovation.

Indeed, even now airliners can take off and land, as well as fly on autopilot with the help of an on-board computer, without human intervention. And the number of pilots on a conventional passenger plane has already been reduced from three to two. Sinnett added that Boeing's interest in unmanned technology is also driven by a shortage of pilots around the world, a problem that will become more acute as global demand for air travel continues to grow.

Sinnett, who is a former pilot, plans to test the new AI-powered technology in a simulator this summer, with the technology to be tested in real-world conditions next year. These will be experimental flights with engineers and pilots on board, but without passengers.

Drones must meet aviation safety standards, for which 2016 was the safest year ever, according to the Aviation Safety Network (ASN), a website that tracks aviation accidents. It will also be necessary to convince regulatory authorities, which have not yet decided how to certify such aircraft, of the safety of their use.
