Hybrid offshore power plant

05.11.2022

One of China's four largest energy companies, State Power Investment Corporation (SPIC), has for the first time put into operation a hybrid offshore power plant - simultaneously powered by wind and solar energy. If the tests go well and the station has to weather storms and typhoons, the project will continue to grow with the prospect of deploying up to 42 GW of offshore hybrid capacity in the region.

The peak power of the first two rafts with solar panels is only 500 kW. The solar energy generated on the rafts is fed to a transformer installed in the wind turbine tower. From the power substation of the wind generator, electricity is sent to the mainland by an underwater cable to consumers.

The project of a hybrid offshore renewable power plant was developed by the Norwegian company Ocean Sun. This is the world's first practical implementation of the development. The Norwegians came up with the design of rafts and anchors so that they could withstand the impact of the elements without the consequences of the equipment.

Next year, the project is planned to be expanded to 20 MW.

In general, hybrid power plants using renewable energy sources make it possible to equalize the supply of electricity due to the natural (daily) spacing of peaks in time for wind and solar generation.

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, ... >>

eVTOL electric flying car 06.01.2023

Aska unveiled the eVTOL electric flying car with a range of 400 km.

The Aska A5 is about the size of a typical SUV and has been described as the first four-seat electric vehicle that can travel on the road and up to 250 miles (402 km) in the air on a single charge. Although the A5 looks more like an airplane/helicopter than a traditional car, it has wings and propellers that can be folded down when it needs to be used as a car.

The vehicle is powered by a proprietary system combining lithium-ion batteries with a gasoline engine acting as an onboard range extender. It's unclear how much power the A5 has, but Aska notes that it has four electric motors in the wheels that provide all-wheel drive traction while also improving aerodynamics and maximizing interior space.

Although the A5 can take off like a helicopter, or use a runway like a traditional plane. During flight, the wings and six rotors deploy. Asuka notes that the wing has been optimized for "glide, smooth landings and energy efficiency."

"Our unveiling at CES represents something that has never been achieved in the world, but what people have been dreaming of for decades: a fully functional, full-scale prototype of the Drive&Fly electric VTOL, a true flying car," described co-founder and CEO Guy Kaplinsky.

"We are making history out of ASKA and defining the next 100 years of transportation. ASKA is positioned as a next-generation vehicle that combines the convenience of a car with the ease and efficiency of VTOL and STOL flight. ASKA is a vehicle not only for consumers, it also has significant business - potential for use in emergency response, military, and shared mobility services on demand."

In addition to private sales of the A5, Aska plans to launch a ride-to-order service in 2026 with a fleet of its eVTOLs.
