It is good to use such an "exotic" lantern in practice to illuminate a palm tree standing next to the window at night. It turns out beautifully.

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, ... >>
| Random news from the Archive Compact charger for BMW electric vehicles
08.08.2014
Bayerische Motoren Werke (BMW), one of Europe's oldest automakers, has announced a new charger for electric vehicles. In addition, it became known about the cooperation of the German brand with the American energy company NRG Energy.
The German automaker, in collaboration with its compatriot Bosch Automotive Service Solutions, has developed a compact BMW i DC Combo Fast Charger charging station, with which electric car owners can fill up to 80% of car batteries with electricity in just half an hour. A fixture in half a home refrigerator weighs about 45 kg and can be mounted on the wall.
A 24kW charger costs just over $6,5, five times the price of other fast battery systems, BMW said.
The novelty uses SAE Combo charging technology, which is promoted by many major brands, including General Motors, Ford, Nissan, Daimler and Volkswagen. Japanese manufacturers such as Mitsubishi and Nissan support another standard for high-speed battery replenishment, CHAdeMO.
BMW is currently working with Volkswagen and Nissan to develop the EV ecosystem in Europe and is in talks to expand its fast-charging network with other players in the automotive industry. At the same time, the Bavarian concern is not going to build its own infrastructure of charging stations.
