Biofuel for aircraft

07.09.2016

Several examples of high-octane waste-based biofuels are currently being tested by major airlines. The main objective of the project is to curb the growth of carbon dioxide pollution of the environment. But how realistic is the transition from oil to waste processing in the fuel industry?

UN representatives intend to approve these types of fossil fuels as one of the key parts of the plan to stabilize and reduce aviation pollution by 2020. However, critics say the strategy will never be implemented due to airlines not taking the problem seriously.

One of the biggest drawbacks of the Paris climate agreement, adopted in December 2015, is that it does not cover emissions from shipping and aviation. Of course, in comparison with the automotive industry, the level of air pollution from aviation emissions seems to be quite small: however, already in 2015 their figure reached 2% of the total amount of harmful CO2 emissions - and this is already serious.

Tests of alternative types of "green" fuels have been carried out repeatedly: for example, in 2008, Virgin Atlantic conducted the first flight, during which dozens of test fuels from oilseeds and animal fats were used. In addition, samples of sawdust jet fuel have been tested by the industry.

The new fuel is made from an alcohol called butanol, which is produced naturally from the fermentation of many foods, such as bread. But, of course, the conversion of the fuel industry to bio-production will be too expensive and take an unacceptably long time. Currently, the cost of 1 gallon of biofuel is $3, which is still almost twice as much as the cost of petroleum-based fuel. This is not to mention the fact that oil tycoons, in the event of switching to an alternative energy source, will lose a significant part of their profits, which may adversely affect the economies of many countries.

As a result, opinions are divided. Of course, the production of fuel from organic waste is preferable: on the one hand, it is not only an environmentally much cleaner way to get energy, but also a completely renewable source of raw materials that does not take tens of millions of years to form. On the other hand, modern industry simply cannot afford such a luxury.

However, such metamorphoses in industry are never instantaneous. Theoretically, if the technology is introduced gradually, while at the same time investing in the development of relevant branches of science, then in a couple of decades you can get a small but steadily developing industry in the fuel production industry, which will gradually reduce the environmental pollution factor to a minimum.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

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, ... >>
