Water from the air

02.06.2009

Only 2% of the water in the air is collected in clouds. The remaining 98% is in the form of an invisible vapor. Every second, the winds transport about 165 tons of water vapor from tropical seas, where evaporation is the strongest, to temperate latitudes. A cubic kilometer of air contains from 10 to 40 tons of water.

Israeli engineer Eitan Bar has developed a device to extract this hidden moisture. The air is driven through a hygroscopic absorber, which captures only water vapor. Then the absorber is heated in a vacuum, while steam is released, it is cooled to condense water.

The unit can operate at a relative air humidity of at least 10% (normal air humidity in the Sahara is 12-25%) and an outside temperature of plus 4 to 45 degrees Celsius. It takes about 0,3 kilowatt-hours of electricity to produce one liter of water.

The company, founded by the inventor, produces models of various sizes, up to large installations that produce 25 cubic meters of water per day.

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, ... >>

Action cameras GoPro Hero5 Black and Hero5 Session 24.09.2016

GoPro has unveiled two new cameras: Hero5 Black and Hero5 Session. Starting with the older model, we note that it costs $400.

Hero5 Black can shoot video in 4K at 30 fps. If you reduce the resolution to 2K or Full HD, the frame rate will increase to 60 or 120 fps, respectively. Also, the device is capable of taking 12-megapixel pictures, even in RAW format.

In addition, Hero5 Black has got a 2-inch touch screen and a GPS module. But that's not all. The camera is able to understand voice commands, which simplifies control in some cases. The novelty is not afraid of water.

The smaller Hero5 Session is not afraid of it either. It lacks a display, a GPS module and can take photos at a resolution of only 10 megapixels. But the possibilities of shooting video do not differ from the older sister. There is also support for voice commands. In addition, for both models, electronic stabilization is announced when shooting video. Unfortunately, GoPro does not indicate the dimensions of the new cameras, nor their level of autonomy. Hero5 Session is asking for $300. It will be possible to buy cameras already on October 2.

Finally, it is worth noting the launch of the GoPro Plus service, which allows you to store videos and photos of the owners of the company's cameras. You will have to pay $5 monthly to use the service. Subscriber cameras will automatically upload new videos and photos to the cloud storage when they access a Wi-Fi network.

Personal cloud storage is limited to 35 hours of video and 62 photos. Where exactly such numbers come from is unclear, but it remains only to accept them as given. Moreover, it should be borne in mind that the video is saved only in Full HD format, and the photo - in 500 megapixel resolution. Subscribers will additionally get access to a library of musical compositions that they can use for free when editing their videos. The service will launch on September 12 and will only support the new Hero29 cameras for now.
