Comments on the article

In Russia, especially in the southern regions, straw and reeds have long been used as fuel. After threshing, the stalks and cobs of corn and sunflower are burned to dry the grain. After harvest, crop residues can serve as fuel.

The process of photosynthesis of organic matter is most active in algae, especially in the smallest ones - phytoplankton. The productivity of formation of organic matter in algae reaches 5 kg per square meter of sea surface per year, which is 2...5 times higher than the productivity of the forest. Sea waves throw algae ashore, which are used as fertilizer and fuel. Dying phytoplankton (sapropel) leads to silting and swamping of lakes and reservoirs. Technologies for the extraction, drying, and burning of algae and sapropel are being developed, but they do not yet have industrial application in the energy sector.

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, ... >>

Carbon dioxide turned into coal 27.02.2019

Researchers at the Royal Melbourne University of Technology (RMIT) have learned how to turn carbon dioxide into particulate carbon.

Technologies already exist to convert CO2 into a liquid that can be stored underground. But this method has significant disadvantages: high transportation costs and the risk of liquid leakage from storage facilities. Turning carbon dioxide into a solid is a much safer and more environmentally friendly approach. However, this was previously only possible at extremely high temperatures.

Now, using liquid metals as a catalyst, scientists have been able to turn carbon dioxide back into coal at room temperature. This is the first step towards developing a reliable and efficient way to cleanse the atmosphere of one of the main greenhouse gases responsible for global warming.

"While we can't literally turn back time, turning carbon dioxide back into coal and burying it in the ground is a kind of rewinding of the climate clock," the scientists say.

They note that the by-product of this process is a synthetic fuel that can be used in industry.
