Which European prince drives a car fueled with recycled wine?

The heir to the British throne, Prince Charles, switched his entire fleet to biodiesel in 2008. Now almost all of his cars run on fuel made from recycled cooking oil after it has been used. Another car, a 1970 Aston Martin given to him by the Queen for his 21st birthday, runs on biofuel from wine. However, it is difficult to reproach Prince Charles for extravagance: only wine produced by English winemakers in excess of the limit set by the European Union is taken for processing.

Random interesting fact from the Great Encyclopedia:

What are gems?

Precious stones have always amazed people. For thousands of years, people wore them as amulets to protect themselves from disease and evil spirits. It was believed that with the help of some gems, their owner was able to predict the future. Other stones allegedly made it possible to determine whether the suspect was guilty or not.

In ancient times, precious stones differed only in color. Rubies are all red stones. All green stones were called emeralds, and blue stones were called sapphires.

Later it became clear that some stones are stronger and more durable than others. It also became clear that the cost of precious stones depends not only on color, brilliance, uniqueness, but also on their strength. For example, today diamonds are considered the most expensive stones because, in addition to their beauty, they have the highest durability compared to other precious stones.

All gems are called precious stones. But, strictly speaking, only the four most expensive stones can be classified as precious: diamond, ruby, emerald and sapphire. Others belong to semi-precious stones, these are opal, amethyst, topaz. Many of the precious and semi-precious stones are closely related.

Diamond, the most expensive of gems, is also the simplest in structure: it consists of one chemical element - pure carbon. Rubies and sapphires are classified as corundum. Rubies have a carmine color due to the presence of a small amount of iron in corundum. And the presence of various oxides gives sapphires different shades of blue and blue.

Most gems include various combinations of "silicates". Topaz and tourmaline belong to the silicate family, as do garnets and jadeites. Some less expensive gems belong to the quartz group, which is made up of pure silica. They include amethyst. Opal is silica containing 5-10% water. By the way, it is believed that opal is one of the few precious stones that bring misfortune to their owners.

Currently, the first attempts are being made to create artificial gems. Among them are diamonds, emeralds, rubies and sapphires. This is not a fake, in fact, these are stones similar to natural ones, only they are created in laboratories!

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. ... >>

Identification of Internet users by fingerprints 23.09.2000

Sony has announced the creation of a reliable and convenient Internet user identification technology. The new FIU-700 integrates a capacitive fingerprint scanner and a public key code generator.

Although the use of fingerprints is not new in identification technology, the device contains a fundamentally new identification scheme, since the comparison of biometric data and pre-entered fingerprints occurs directly in the device, and therefore the entered parameters do not enter the external network (they do not even enter the computer ).

The mass of the device connected via the USB port is only 35 g, dimensions are 85x54x9 mm.
