Efficiency — as a technical term may refer to: * Algorithmic efficiency, optimizing the speed and memory requirements of a computer program * Efficient energy use, useful work per quantity of energy ** Energy conversion efficiency, desired energy output per… … Wikipedia
Fuel efficiency in transportation — This page describes fuel efficiency in means of transportation. For the environmental impact assessment of a given product or service throughout its lifespan, see life cycle assessment. Caveats Comparing Fuel efficiency in transportation is a bit … Wikipedia
Spacecraft propulsion — A remote camera captures a close up view of a Space Shuttle Main Engine during a test firing at the John C. Stennis Space Center in Hancock County, Mississippi Spacecraft propulsion is any method used to accelerate spacecraft and artificial… … Wikipedia
Marine propulsion — For the operation of ship engines, see Engine department (ship). For the design of ships, see Naval architecture. A view of a ship s engine room Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across… … Wikipedia
Beam-powered propulsion — is a class of spacecraft propulsion mechanisms that use energy beamed to the spacecraft from a remote power plant. Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides… … Wikipedia
Distributed propulsion — For distributed propulsion on rail see: Multiple unit Distributed propulsion (DP) is a type of powered flight propulsion system for fixed wing aircraft in which airflows and forces are distributed about a vessel. Its goal is to increase… … Wikipedia
Fuel efficiency — is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per… … Wikipedia
Project Orion (nuclear propulsion) — An artist s conception of the NASA reference design for the Project Orion spacecraft powered by nuclear propulsion. Project Orion was a study of a spacecraft intended to be directly propelled by a series of explosions of atomic bombs behind the… … Wikipedia
Alternative propulsion — is a term used frequently for powertrain concepts differing from the internal combustion engine concept used in only petroleum fueled vehicles.DefinitionThe term alternative propulsion or alternate methods of propulsion includes both *… … Wikipedia
Propulsive efficiency — In aircraft and rocket design, overall propulsive efficiency eta is the efficiency, in percent, with which the energy contained in a vehicle s propellant is converted into useful energy, to replace losses due to air drag, or gravity, or to… … Wikipedia
Dual mode propulsion rocket — Dual mode propulsion systems combine the high efficiency of bipropellant rockets with the reliability and simplicity of monopropellant rockets. Dual mode systems are either hydrazine/N2O4, or MMH/hydrogen peroxide (the former is much more common) … Wikipedia
