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 ... >>

Mini air conditioner Sony Reon Pocket 5 09.05.2024

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 ... >>

Germany and the UK will be connected by a high-voltage cable 1,4 GW 29.07.2022

Another step has been taken towards the construction of a 1,4 GW high-voltage cable connecting Germany with the UK. A consortium of 20 lenders led by the European Investment Bank (EIB) has agreed to provide €400m ($406,5m) for the NeuConnect interconnector project, a €2,8bn high-voltage DC link connecting Germany to the UK.

"The investor consortium is led by French investor Meridiam, Allianz Capital Partners and Japan's Kansai Electric Power," the EIB said in a statement. There are other banks besides the EIB, notably the UK Infrastructure Bank and the Japan Bank for International Cooperation (JBIC).

Construction on the project should begin before the end of this year, and completion is scheduled for 2028.

The predominantly submarine cable will be 725 km long, with a power of 1,4 GW and a DC voltage of 525 kV. It will connect a Tennet-operated converter station near Fedderwarden in Germany to the National Grid-operated UK network via a converter station on the Isle of Grein.

The German conglomerate Siemens will build the converter stations, while cable manufacturer Prysmian will lay the cable.

In September 2020, Tennet and National Grid announced a cooperation agreement to explore the possibility of connecting Dutch and British wind farms to the power systems of both countries using underwater electrical cables called interconnectors.

Under the terms of the cooperation agreement, the two grid operators will explore the development of a Multi-Purpose Interconnector (MPI) to connect up to 4 gigawatts of UK and Dutch offshore wind power simultaneously between the British and Dutch power grids, providing an additional 2 GW of capacity.
