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. ... >>

Hypersonic missiles instead of drilling rigs 18.08.2015

Geothermal energy has served mankind since time immemorial. As far back as ancient Rome, hot springs were used for public baths and floor heating, and in the 12th century, France built the first central heating system using natural heat. Around 000 MW of geothermal electricity are currently generated worldwide, with an additional 28 GW used for heating, spas, industrial processes, desalination, and more.

However, in order to release steam from underground, wells several kilometers deep are needed, each of which costs from $5 million to $20 million, depending on the depth. A much cheaper, albeit untested, method was proposed by the American company HyperSciences. Its founder, Mark Russell, has received a patent for drilling holes in the earth's crust by bombarding it with hypersonic missiles.

A rocket with a special abrasive core is installed in an accelerator based on a ramjet engine, which serves both as a chamber and as the barrel of this "gun". Gas is injected into the accelerator, which ignites and creates high pressure in the chamber with the rocket, which allows it to fly out at a speed of 2 km / s. This is enough, according to the author, to crush any rock, the remains of which are then sucked out of the well. For greater efficiency, the author suggests using installations of several accelerators.

The design of the rocket itself is described in the patent in very general terms, but the author suggests that it can be equipped with a plastic explosive tip to increase drilling intensity. Temperature and depth sensors can also be placed there.

The lack of details hasn't stopped Russell from getting $1 million in grants from oil company Shell through the GameChanger program, which funds even the most fantastic projects that could affect energy production in the future.
