To control the electrolyte level in the battery banks, you can use a simple device, the device of which is schematically shown in the figure. It consists of two rods (narrow strips of stainless steel) of different lengths, rigidly fixed in a 5...8 mm thick organic glass base, to which HL1 and HL2 incandescent lamps are connected. rated for the voltage corresponding to the voltage of the tested battery. Depending on the type of battery, the length of the short rod can be 13...14, the long one - 20...22 mm.
A flexible insulated wire 350 ... 400 mm long with a pointed wire probe at the free end is soldered to the connection point of the lamps.
After removing the cork, the indicator rods are inserted into the jar through the filling hole to the base and touch one of the battery terminals with a flexible probe. If at the same time none of the lamps is lit, then the electrolyte level in the checked bank is below the permissible level. The glow of only one HL2 lamp will indicate that the electrolyte level in the bank is below normal, both lamps - the level is normal.
The brightness of the glow of the lamps depends on the number of batteries included in their power circuit.

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. ... >>
| Random news from the Archive solar pyrotechnics

Any talk of electricity these days is viewed through the prism of ever-falling oil prices, which a just-released report from investment bank Goldman Saks has suggested could drop to $20 a barrel. And, since the prism (if we continue the analogy) does not reflect, but refracts light, none of the participants in such a conversation can shed light on why the prices for gasoline or fuel oil, if they fall, then very slightly and in individual countries, but for electricity remain almost unchanged.
Even photovoltaic panels that use free energy from the Sun do not help, since the cost of panels, despite government subsidies, remains very high. And even in Germany, which abandoned nuclear power plants and tries not to pollute the atmosphere with its cheap coal, electricity prices in 2015 for the first time in 10 years fell by an average of 1%, but still remain at the level of 25 cents per kilowatt-hour. True, this price includes 16% VAT, 7% electricity tax, 6% tax on the use of public space for power transmission towers, and 21% tax in favor of renewable energy sources.
The latter tax does not exist only in Germany, and it is from these funds that various advanced developments in the field of solar energy are financed. One of these developments is the invention of South Korean scientists from Yonsei University, which is a hybrid of photovoltaic and pyroelectric effects. The first is characterized by the appearance of a voltage or electric current in a substance under the influence of light, the second - by the appearance of an electric field in the material when its temperature changes.
Similar hybrid devices have been created before, but South Korean researchers claim that the efficiency of their device is 20% higher than that of a conventional solar panel, and the amount of energy produced is five times greater than that of competing hybrids.
The device uses a Graetzel cell - a dye-sensitized solar cell, which is mounted on a transparent electrically conductive film made of PEDOT (3,4-ethylenedioxythiophene) polymer. Under this film there is another film of pyroelectric material with a thermoelectric converter. When sunlight or other light of the same spectrum hits a photovoltaic cell, it generates electricity. Light that does not hit the cell passes through the polymer film and heats it up. The thermoelectric converter then uses the heat to generate additional electricity.
