green mouse

13.08.2002

This is the name of a pocket generator for recharging cell phone batteries, proposed by the French inventor Stefan Hugenin.

Outwardly, this device weighing 110 grams really resembles a computer mouse, but with the essential difference that it can and should be pulled by the tail. The handle protruding from the rear end of the "mouse" must be pulled several times, as when starting a boat motor. The generator located inside is untwisted, from which the phone is recharged.

At the front end of the device there is a white LED that lights up when a button is pressed, so that the "green mouse" also serves as a flashlight, the light of which is visible from a distance of up to a kilometer.

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 ... >>

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, ... >>

Repeater antennas - from sea water 30.01.2016

The construction of repeater antennas is a costly, cumbersome and time-consuming process. Multi-meter iron trusses are installed on the foundation - all this requires lengthy preparation and is not justified as a temporary solution. To get away from the process of building antennas, Mitsubishi Electric proposed and tested an interesting method in practice. A column of sea water was used as a transceiver antenna. Salt sea water is a conductor for current. Something, but there is more than enough sea water around Japan.

Mitsubishi has developed a repeater design that feeds a high-frequency signal into the water jet. A channel is also created for receiving a signal coming from the water column. The development was named "Sea Aerial". The nozzles of the jet pump are isolated, and the high-frequency current does not go beyond the complex with the transmitter. Such a complex can be towed by a boat to a given point and deployed in a matter of minutes. The system requires only sea water to operate.

The system proposed by Mitsubishi has been tested as an on-air television repeater. In practice, it turned out that the efficiency of an antenna made of sea water is 70%. About 30% of the power is lost due to the poorer conductivity of water when compared with the current conductivity in metal. The losses have to be compensated by increasing the transmitter power. However, this is an acceptable loss, given that the antenna in its traditional form is no longer needed.

The company is confident that this direction will become a good business. The only limitation will be that the proposed technology is not suitable for a high frequency signal. Cellular and Wi-Fi pass by. However, the length of the radio wave involved is determined by the configuration of the water pump nozzle. Perhaps the company will be able to come up with something suitable for relaying a high-frequency signal.
