Non-nuclear submarine Taigei

08.08.2021

The first Japanese diesel-electric submarine of the new generation "Taigei" entered the factory sea trials. This became possible just 14 months after her launch. The Taigei will be handed over to the Japan Maritime Self-Defense Force in March next year.

Mitsubishi Heavy Industries Corporation has been developing a new generation diesel-electric submarine since the early 2010s under the 29SS project. It should replace the aging ships of the Soryu type. Soryu can reach speeds of up to 20 knots. Their underwater displacement is 4,2 thousand tons with a length of 84 meters and a width of 9,1 meters.

According to the 29SS project, it is planned to build a series of seven ships. The first of them, Taigei, was launched in October last year. It is distinguished by the reduced dimensions of the cabin, partially integrated into the ship's hull. This should reduce hydrodynamic resistance when moving in a submerged position and reduce battery charge consumption.

With a length of 84 meters and a width of 9,1 meters, the displacement of the Taigei is three thousand tons. Like the last two Soryu-class ships, it is equipped with lithium-ion batteries instead of traditional lead-acid batteries. Of the armament, Taigei has six tube launchers of 533 mm caliber for torpedoes and cruise missiles.

14 months after the launch, the Taigei left the factory sea trials. This is the second stage of testing any ship. It checks on-board equipment in real conditions and the compliance of the vessel with design characteristics, such as speed, stability and propulsion. "Taigei" will become the 22nd ship of the Japanese submarine fleet. The Japan Maritime Self-Defense Force is due to receive it next March.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Traces of the first Europeans 18.11.2003

On the western slope of the extinct volcano Roccamonfina, 50 kilometers from Naples, archaeologists from the University of Padua discovered traces of three human beings left 325-385 thousand years ago.

They were representatives of the "upright man" species. Their growth is estimated at one and a half meters, foot size - 34th. The distant ancestors of Europeans, descending from the mountain, walked along a layer of volcanic ash, which later petrified, preserving footprints. One of the walkers slipped and left a handprint on the ashes. These are the oldest human footprints in the world, and the oldest hominin footprints are found in Tanzania - they are about 3,5 million years old.

It is curious that the locals, having known these footprints for a long time, considered them to be the footprints of the devil: who else can walk along the volcano, leaving prints in the stone?
