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, ... >>

Electric generator runs on friction 25.07.2012

In a study funded by the National Science Foundation, the Department of Energy and the US Air Force, scientists have managed to develop an original triboelectric generator that produces electricity from the friction of two surfaces.

Researchers have discovered another way to collect small amounts of electricity by capturing the electrical charge produced by rubbing two different types of plastic. A new type of generator can generate energy through habitual activities such as walking. It can also be used in various nanodevices and self-contained pressure sensors with low power consumption.

The triboelectric generator consists of sheets of polyester and polydimethylsiloxane (PDMS). When the two sheets are rubbed, the polyester donates electrons and the PDMS accepts them. This creates an air gap that isolates the charge on the surface of the PDMS and generates a dipole moment. As a result, when an electrical load is connected, a small current is generated between the two surfaces. If you constantly rub the plates of materials against each other, the generator will continuously generate electricity. The scope of the new device is expanded by the fact that polyester and polydimethylsiloxane have a transparency of 75%. This allows the new generator to be embedded in the surface of the touch screen, which can thus generate energy from the touch of the user's fingers.

The scientists studied various microtextures on the surface of the new generator and found that the tiny pyramids produced the largest current of about 0,13 μA per square centimeter at a rather high voltage of 18 V.
The developers note that the manufacturing technology of the triboelectric generator is simple and low cost, which allows it to be scaled up to large-scale production and practical application. At the same time, the reliability of the device is very high - it continues to generate energy after more than 100 thousand cycles.
