Life at the wind turbine

01.09.2011

A windmill in the sea creates a new habitat and enhances biodiversity. On land, not many people like wind farms - they are very noisy during operation. Therefore, now in the northern countries of Europe (and it is there that alternative energy is advancing by leaps and bounds) they are being removed farther into the sea: there the wind is fresher, and there are no people. And how will windmills be perceived by marine life?

A two-year study on this topic was carried out at a power plant near Emond aan Zee by Dutch scientists led by Professor Han Lindebum from Wageningen University. The construction of an artificial reef and the installation of windmill supports did not affect the bottom organisms. On the other hand, all kinds of foulers received a significant space for life - both the slopes of the reef and the elements of the supports were overgrown with shells, anemones and other similar creatures. Crabs also settled there.

Around the turbines, a lot of fish were bred, including commercial species like cod. The reason is clear: fishing is prohibited in the area of the power plant, so the fish have mastered the shelter. Some species of birds that avoid turbines can be recognized as more or less affected. However, other birds, on the contrary, like to fish near the power plant. As for the victims among them from a collision with the blades, they turned out to be very few.

In general, scientists note, if you design offshore wind farms wisely, then it is quite possible to avoid unpleasant consequences for the environment.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Robots work inside people 04.06.2023

US scientists have developed miniature robots capable of delivering medicines directly to the affected organ. Biological "fins" - bacteria and spermatozoa with a non-linear nature of movement were taken as the basis.

Microrobots made from biocompatible polymers have a spherical cavity inside. Devices vibrate and move. The works also have asymmetrical fins, causing them to orbit. The mechanism has already been tested on the bladder of a laboratory mouse.

A group of microrobots was able to attach to the wall of the bladder and transfer more than 90% of the drugs to the organ in 2 days. It is believed that this will allow more effective treatment of various diseases and reduce side effects.
