Soil water

03.07.2003

The German company "Zeltek" proposed a device, ingenious in its simplicity, for evaporating pure water from the soil.

This is a large cone made of transparent polymer, without a bottom, but with an annular groove along the perimeter of the base (the edge of the base is bent inward). The cone is placed on the ground, and the rays of the sun drive water out of the ground. Water, evaporating under the cone, as in a greenhouse, settles on the walls and flows into the receiving groove.

In a day, even in the desert, you can get up to one and a half liters of the purest water - although the sand of the desert is drier than ordinary soil, but the sun is hotter there. You can put the cone in a dirty puddle, or even in calm weather let it swim near the shore in shallow sea water - and get clean distilled water.

The invention was awarded the prize of the World Forum on Drinking Water Problems, held in the spring in Tokyo.

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, ... >>

whiskey fuel 03.11.2021

Edinburgh University professor Napier Martin Tangny was able to create fuel from whiskey. To do this, he resorted to the process of fermentation. According to the professor, such biofuels can replace gasoline.

Startup Celtic Renewables was founded, which is engaged in the creation of biological fuels. It is noteworthy that the production of Whiskey in Scotland is very developed. The drink is made from barley, yeast and water. Often, waste from production is used as animal feed, sometimes they are simply thrown into the sea.

As for the new fuel, it is produced on the same principle as acetone, butanol and ethanol. The technology for the manufacture of these substances was developed a hundred years ago. Professor Martin Tangny improved the technology and adapted it to create biofuels.

The startup's factory is located in Grangemouth.
