Methane fermentation in the processing of agricultural and domestic waste makes it possible to obtain biogas with a methane content of about 70% and about 15% carbon monoxide, as well as disinfected organic fertilizer. 1 kg of organic waste yields approximately 1 liter of biogas. The calorific value of biogas is 22.24 MJ/kg. The duration of the fermentation process is 5.7 days. Biogas fermenters are widely used in China, Japan, and the USA. In modern agriculture, with growing demand for fuel and fertilizers, the processing of waste from agro-industrial complexes, livestock farms, and slaughterhouses using biogas technologies allows solving the problems of drying hay, grain, heating farms and residential premises, and generating electricity.

In the People's Republic of China, remote rural areas are gasified with the help of plants that process organic agricultural waste. Each such individual installation of a peasant household produces about 6500 kWh per year. electricity and 5 tons of organic fertilizer.

In Russia, the task is to produce and introduce equipment for the use of biogas. The EcoRos Center has developed an autonomous biogas-energy module, which includes bioreactors, a sump, a gas holder for biogas storage, a hot water boiler and a gas distribution system for feeding gas stoves and farm heating installations. The module processes up to 1 ton of livestock farm waste per day and produces up to 230 kWh of thermal energy and up to 40 nm of biogas containing about 60% methane and up to 15% carbon monoxide.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Elevator to space 18.08.2016

The Canadian company "Thoth Technologies" announced its plans to connect the Earth and the stratosphere. Specialists are going to build an elevator into space with a twenty-kilometer shaft.

It is planned that the tower of nanoblocks will allow you to send people into space without a rocket. At its top, a platform will be placed that tourists can visit, in addition, it will be able to serve as a communication point and a runway for spacecraft.

The idea of such an elevator belongs to the company "Thoth Technologies". Project engineer Brendan Quinn notes that the tower he created will make it possible not to use rockets to send people into space. The astronauts will climb to the top with the help of an elevator that will develop superspeed. Spaceships will receive only one stage, which will allow them to refuel directly in the stratosphere.

Canada is not the first country to develop a building to connect Earth and space. Two years ago, developers from Japan announced their plans to build an elevator into space by 2050, which would be a breakthrough in the field of orbital flights. Obayashi's design is based on carbon nanotubes, which will create a design that would be extremely reliable at the lowest possible weight.
