These vehicles are propelled by at least one electric motor. [1] [2] Good example is an electric locomotive that is drawing power directly from overhead wire or third rail. "Electric vehicle" is often cleverly interchanged with "Electrified vehicle" [3] which doesn't specify what kind of powertrain vehicle actually has. Electric vehicles do not ...

Armadillo Aerospace's quad rocket vehicle showing shock diamonds in the exhaust plume from its propulsion system. Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid.

A single laser facility on the ground can in theory launch single-stage vehicles into low or high earth orbit. The payload can be 20% or 30% of the vehicle take-off weight. It is far more economical in the use of mass and energy than chemical propulsion, and it is far more flexible in putting identical vehicles into a variety of orbits."
Yamato 1 on display in Kobe, Japan.The first working full-scale MHD ship. A magnetohydrodynamic drive or MHD accelerator is a method for propelling vehicles using only electric and magnetic fields with no moving parts, accelerating an electrically conductive propellant (liquid or gas) with magnetohydrodynamics.
