Comments on the article

For experience you need:

durable paper towel;
food foil;
scissors;
copper coins;
salt;
water;
two insulated copper wires;
small light bulb.

Make a battery

1. Dissolve some salt in water.

2. Cut paper towel and foil into squares slightly larger than coins.

3. Wet paper squares in salt water.

4. Place a stack on top of each other: a copper coin, a piece of foil, a piece of paper, another coin, and so on several times. There should be paper on top of the stack, and a coin at the bottom.

5. Put the stripped end of one wire under the pile, attach the other end to the light bulb. Put one end of the second wire on top of the stack, and connect the other to the light bulb as well. What happened?

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. ... >>

Charging station Tesla Supercharger V3 07.03.2019

Tesla introduced the Supercharger V3 charging station. In a related announcement, the manufacturer noted that its network of more than 12 electric vehicle charging stations in North America, Europe and Asia continues to grow. Already, more than 000% of the US population is covered by the network, and by the end of 99, a similar figure should be reached in Europe.

Station V3 differs from its predecessors in the increased speed of charging. This required the use of a new 1 MW power cabinet that supports peak power up to 250 kW per vehicle. With this power, the Tesla Model 3 Long Range electric car can charge enough in 5 minutes to travel 120 km (charging speed - 1600 km per hour). Combined with other improvements, this will reduce the time customers spend on charging by an average of 50%, according to the manufacturer. Typical charging time will be reduced to about 15 minutes.

An interesting innovation that will speed up charging will be the heating of the battery at the entrance to the charging station. The optimal temperature is said to reduce the average charging time by 25%.
