Taking into account traffic flow, the greenhouse effect, pollutant emission, and noise emission, it seems that electric mobility is the best alternative for transport in urban areas. Nevertheless, as shown in Chap. 1, these unique characteristics are prejudiced by severe disadvantages regarding the sources of electric energy (Fig.

As we have seen in previous chapters, chemical propulsion systems are limited in performance by the energy stored in their propellants. This limitation can be overcome by using electric power available on the spacecraft (e.g., from solar arrays, nuclear reactors or beamed energy sources such as laser light or microwave energy transmitted to the ...

Electric and Hybrid-Electric Propulsion Systems
2013While in conventional ICE-based vehicles the energy carrier is a fossil fuel, electric and hybrid-electric propulsion systems are characterized by the presence of an electrochemical or electrostatic energy storage system. Moreover, at least one electric motor is responsible — totally or partially — for the vehicle propulsion.

Electric space propulsion systems
Space Science Reviews, 1967Active development of electric thrustors began 10 years ago. Today, several kinds of thrustors have achieved efficiencies above 90 % and lifetimes of several thousand hours. The following article derives the basic theory of electric thrust production at constant exhaust velocity, and at variable exhaust velocity programmed for optimum vehicle ...
