An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. Three main types of electric vehicles exist, those that are directly powered from an external power station, those that are powered by stored electricity originally from an external power source, and those that are powered by an on-board electrical generator, such as an internal combustion engine (a hybrid electric vehicle) or a hydrogen fuel cell. EVs include electric cars, electric trains, electric lorries, electric aeroplanes, electric boats, electric motorcycles and scooters and electric spacecraft. Diesel submarines operating on battery power are, for the duration of the battery run, electric submarines, and some of the lighter UAVs are electrically-powered. Proposals exist for electric tanks.
While the first electric public transport vehicle become operational more than a century ago when the first trolleys rolled on the streets of Europe’s capitals and America’s major cities, development towards autonomous electric public transportation hasn’t really developed that much since then. Sure power and efficiency has evolved tremendously, but the working principle is more or less [...]
When left in scarcity, the human mind has always been pressured to find a solution. In the past decade or so, the demand for rare earth metals has soured as ever expansive green technology required it. The problem however, is that not only do these metals come in short supply, but they’re actually controlled in their [...]
IBM has teamed up with Zapadoslovenska energetika (ZSE), the biggest electric company in Slovakia, for a feasibility study which aims to prepare Bratislava, the nation’s capitol, for plug-in electric vehicles. With this in mind, the companies will look at the best way to develop a “green highway” between Bratislava and the neighboring Austrian city of Vienna, which is about [...]
