Three-wheeled electric car

08.05.2002

Single three-wheeled electric car "Sparrow" ("Sparrow") is produced in the United States.

The creators of the car proceeded from statistics: 87% of Americans live at a distance of 29 kilometers or closer from their work, and 93% of those who drive to work in their car drive alone in four-seater or even more spacious cars. This means that a single-seat electric car will be popular.

True, it costs 17 thousand dollars, like a quite decent gasoline subcompact car, but you can save on operating costs. Electricity is cheaper than gasoline, especially for such a light crew (weight without a driver is 612 kilograms). Insurance and parking fees are taken as for a motorcycle.

Thirteen lead-acid batteries after charging for 6 hours provide an hour of driving at a speed of 95 kilometers per hour (maximum speed 110 kilometers per hour).

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Fuel batteries - capacity tripled 21.10.2005

Fujitsu Laboratories, in collaboration with NTT DoCoMo, has developed a high-capacity fuel cell prototype as well as a prototype methanol-powered external mobile phone charger.

In both cases, methanol of a higher concentration is used - over 99%, instead of the previously used 30%. This allows you to charge the batteries of three mobile phones with a consumption of only 18 ml. methanol.

In theory, fuel microbatteries with the same occupied volume are ten times more efficient than typical lithium ion batteries and three times more efficient than the stored energy density. In addition, methanol can be obtained from biological waste, which makes it possible to reduce environmental pollution along the way.

According to Fujitsu, a single fuel microcell using high concentration methanol can produce 1 watt of power.
