    Spright will initially launch as a pilot project in Kansas, ahead of plans to rollout a service delivering medical supplies by drone across the US

    Back in April, Wingcopter launched its flagship eVTOL fixed-wing delivery drone, the Wingcopter 198, and now the German drone maker has formed a strategic partnership with Air Methods to create a healthcare-specific drone delivery network across the US.

Founded in 1980, Air Methods currently has a fleet of 450 helicopters and fixed-wing aircraft at more than 300 bases across 48 states in the US, which make almost 100,000 deliveries of medical supplies and equipment per year to hospitals and people, mostly in rural areas.

Wingcopter's 65 x 198 x 152 cm (25.5 x 77.9 x 59.8 in) flagship eight-rotor drone can rise up vertically like a helicopter and then transition to fixed-wing horizontal flight once in the air.

              While higher prices for EU and UK carbon allowances have given gas a competitive edge over coal in power production, offshore gas producers look set to be negatively affected as the era of free allowances is coming to an end. [Gas in Transition, Volume 1, Issue 4]

by: Andreas Walstad

Until 2021, when the fourth phase of the EU’s emissions trading system (ETS) came into force, both oil and gas producers received a high number of EU carbon allowances for free. However, free allocation is now being phased out for gas, albeit not for the oil sector. The reason is that natural gas extraction is not included in the carbon leakage list for the 2021-2030 period which covers the fourth phase of the ETS. Carbon leakage refers to the risk of energy intensive sectors relocating to other jurisdictions if the cost of polluting in the EU is too high. EU regulators consider the oil industry more prone to carbon leakage compared with gas. For example, an energy intensive oil refinery is considered more likely to be relocated overseas than a gas processing pl...

             With US sanctions still in place and EU legislative obstacles looming, however, the Russian project is not out of the wood just yet. [Gas in Transition, Volume 1, Issue 3]

by: Joseph Murphy

    Russia's embattled Nord Stream 2 is now tantalisingly close to completion, with the project's operator confirming to NGW on June 4 that the pipelaying work on its first string is now complete. "The laid pipeline sections need to be connected and thereafter the required pre-commissioning activities will be carried out," the Gazprom-owned Nord Stream 2 operating company said in a statement. "Pipelay works on the other line are continuing." The update comes weeks after the Biden administration said it would not go ahead with further sanctions against Nord Stream 2, in the interest of maintaining good ties with Germany’s government, which remains a staunch supporter of the project. “Our opposition to the Nord Stream 2 pipeline is unwavering,” US secretary of state Anthony Blinken said on May 19. &ldqu...

                          Nokia - Business Enviroment Analysis

    Nokia has today announced its private wireless Nokia Digital Automation Cloud (DAC) 5G standalone solution has been selected by the Estonian company Thinnect OÜ to enhance the Estonian Cyber Range’s Industry 4.0 capabilities. This is part of the cyber defence project initiated by the Estonian Ministry of Defence on threats related to emerging technologies. 

With the evolution to Industry 4.0, industrial sectors are increasingly relying on digital systems to run their operations, exposing them to new cyber-attacks. To better protect networks and data, as well as national critical infrastructure, military agencies around the globe are investing in cybersecurity training.

Oamenii de știință creează o formă cristalină solidă de electroni în laborator PDF Imprimare

  An artist's impression of the structure of a Wigner crystal made of electrons (red) inside a semiconductor material (blue and gray)

   Researchers at ETH Zurich have created a crystal made entirely of electrons. The structures have been theorized for decades, but this marks the first time they’ve been experimentally confirmed in the lab.

   Normally, electrons behave more or less like a liquid, flowing freely through a material. But in 1934, theoretical physicist Eugene Wigner predicted that a group of electrons could crystallize into a solid form under specific conditions, forming a phase now known as a Wigner crystal.

s: their electrostatic repulsion and their motional energy. The latter is the more powerful effect, causing electrons to bounce around at random, but if that could be reduced enough, Wigner proposed, then the repulsion could take over, locking the electrons into a uniform lattice.

    But that proved trickier than it may sound. The density of electrons needs to be lowered beyond a certain point, they need to be confined in a “trap”, and they need to be cooled almost to absolute zero, to reduce outside influence on their movement.
