Unmanned train from Deutsche Bahn and Siemens

14.10.2021

German railway operator Deutsche Bahn and industrial group Siemens have unveiled an automated, unmanned train in Hamburg that will follow the routes of the city's S-Bahn high-speed train network. The developers claim that it adheres to the schedule more accurately and is more energy efficient than traditional railway solutions.

Four of these trains will begin operating on the S-Bahn urban high-speed rail network as early as December, using the existing rail infrastructure. While other major cities like Paris already have automated subway trains or monorail solutions running between airport terminals, the Hamburg version will be the first to use the same roads as conventional passenger trains operated by train drivers.

The project, described by Siemens and Deutsche Bahn as a "world's first", is part of a $60 million plan to modernize Hamburg's high-speed rail system.

Deutsche Bahn chief Richard Lutz has already said that automated trains provide a "more reliable" service, without the need to lay even one extra kilometer of new tracks. Siemens believes that driverless trains transport approximately 30% more passengers, allow significant cost savings (up to the same 30%), and are generally much more punctual.

Although the train is digitally controlled and fully automated, the driver will still be present in the cab when transporting passengers in case of an emergency.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Created the world's strongest electromagnet 19.06.2019

Scientists at the University of Florida's National High Magnetic Field Laboratory (MagLab) have set a new record for the strongest permanent magnetic field generated by a new electromagnet with superconducting coils. In the same laboratory is the previous holder of this record, an electromagnet that generates a field with a force of 45 Tesla, and a new electromagnet produces a field with a force of 45.5 Tesla. It doesn't sound like a huge breakthrough, but it does pave the way for even more powerful magnets based on the use of superconductivity.

Note that scientists have long been creating strong magnetic fields using inductors called solenoids. When an electric current passes through the windings of a coil, it creates a magnetic field. An increase in the strength of the current flowing through the windings leads to an increase in the generated magnetic field.

The 45 Tesla electromagnet was the strongest DC electromagnet for nearly two decades. This device was the key device around which all MagLab activities were concentrated, but in this laboratory there is also another magnet with windings "having electrical resistance", roughly speaking, a copper coil that produces a magnetic field with a force of 33.6 Tesla. The windings of this magnet carry a power of 31 MW, and in order to remove the generated heat from them, it is necessary to pump thousands of liters of pre-chilled water.

Created in the MagLab laboratory, the new electromagnet is called "Little Big Coil 3", its assembled size does not exceed the size of a beer glass. Its superconducting windings are not made from the traditional tin-niobium alloy, but instead use a new REBCO (rare-earth-barium-copper-oxide) material that becomes superconductive at a higher temperature. The thickness of the tape of this material does not exceed the thickness of a human hair, which makes it possible to wind it very tightly. The scientists replaced the insulating material with a new material that does not affect the superconductivity of the windings and does not distort the generated magnetic field. This whole set of measures made it possible to increase the current density in the windings and obtain a record strength of the field generated by them.
