Hydrogen-electric aircraft Odonata

17.11.2023

German manufacturer Odonata has unveiled an innovative hydrogen-electric aircraft that will soon be used for short-haul passenger transport. This air transport has a vertical take-off and landing system, which makes it possible to do without large runways and specialized infrastructure.

Odonata represents the promise of a new era in air travel, combining hydrogen energy and electric mobility. Despite technical and safety challenges, the new aircraft reflects the desire for a clean and efficient aviation future.

Engineers emphasize that this is not another electric aircraft (eVOLT), but an aircraft operating on a hydrogen-electric propulsion system. The hydrogen fuel generates electricity by charging the batteries, while the six propellers that control the aircraft are powered by built-in batteries without interacting directly with the hydrogen. When fully loaded, the aircraft can cover a distance of 1000 km.

Compared to competitors in the eVOLT segment, which have a range of 100-300 km, the new hydrogen aircraft, which does not yet have an official name, promises to meet the needs of short flights in Europe or the United States. It's important to note that comparisons with traditional electric aircraft are not entirely appropriate here, since eVOLTs are powered by a battery charged from the grid, unlike a hydrogen aircraft.

One of the advantages of the new product is that there is no need for a complex infrastructure for refueling, since hydrogen is easy to transport and its refueling takes much less time compared to its electric counterparts. However, there is a problem with the explosiveness of hydrogen, which the developers intend to solve.

Until 2030, it is planned to produce a production model capable of transporting eight passengers, a pilot and cargo weighing up to 800 kg over a considerable distance without harmful emissions into the atmosphere.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Robot builds a brick house in two days 27.07.2016

Australian company Fastbrick Robotics has created a robot that can build a typical cottage in two days. An automatic device named Adrian lays bricks faster than normal builders, and his "labor" costs 10% less.

The robot was named after the Roman emperor Andrian, who in 122 erected Hadrian's Wall in Europe - a defensive fortification stretching over 100 kilometers. The machine can lay 225 bricks per hour. For the average builder, this amount of work takes about half a day.

The head of Fastbrick Robotics, Mike Pivak, and his cousin Mark, who developed Andrian, are now working to create a more advanced device - a robot capable of laying up to a thousand bricks per hour. They plan to sell robots in the US.

Earlier, Boston Dynamics, known for its humanoid robot ATLAS, introduced a four-legged robot retriever that can follow typical dog commands. The robot can also bring drinks and wash dishes.
