The method makes it unnecessary to store or transport hydrogen – two major challenges in creating a hydrogen economy, said Jerry Woodall, a distinguished professor of electrical and computer engineering at Purdue who invented the process. “The hydrogen is generated on demand, so you only produce as much as you need when you need it,” [...]

Human activities have dramatically increased the rates of species and population extinction. This directly undermines the richness and diversity of life on Earth and indirectly threatens human welfare, e.g., through negative effects of species loss on ecosystem services. The causes of biodiversity loss are relatively well understood, with habitat destruction, climate change, monocropping, resource extraction, [...]

Ekranoplan vehicles benefit from the peculiarities of aerodynamics close to a surface.  The proximity of the surface both compresses the air under the wing, giving it more lift, and reduces the drag from the wing, making it more efficient.  This effect increases as the surface gets closer and so is the basis for self-stabilisation in [...]
