How can we distribute electricity more efficiently?
Magnesium diboride superconducting cables! A new superconducting prototype cable has been developed to aim to create superconducting transmission lines for improved efficiency and less of an environmental impact for the electricity grid. To meet future energy demands, all the electricity grids throughout Europe will need to be upgraded and expanded for higher transmission capacity. For …

Carbyne: Officially the strongest material in the world
Scientists in Vienna have successfully created a stable form of carbyne, the world’s strongest material. Carbyne is a linear acetylenic carbon – an infinitely long carbon chain. It can be considered as a one-dimensional allotrope of carbon. Carbyne has a chemical structure with alternating single and triple bonds: (−C≡C−)n. This structure of carbon gives an …

Basic rocket propulsion
Newton stated in his third law that every action must have an equal and opposite reaction. This has proved extremely useful for rocket propulsion as the law demonstrates that if a large amount of fuel is rapidly ejected from the back of a vessel it is quite clear that there is a large force acting …
Beyond the Dreamliner: Blended Wing-Body Aircraft
Pollution is the most significant challenge that the aviation industry encounters nowadays. Air travel is the world\’s fastest growing source of greenhouse gases like carbon dioxide, which cause climate change. Globally the world\’s 16,000 commercial jet aircraft generate more than 700 million tonnes of carbon dioxide (CO2), the world\’s major greenhouse gas, per year. Indeed …
