In this section, the main characteristics of alternative electrical energy storage systems, such flywheels and super capacitors, are described, as these devices might play an important role in the development of vehicles powered by electric propulsion systems. 

Pure electric propulsion systems have been in use throughout the 20th century prior to 1910, EVs held a considerable fraction of the personal transportation market that did not wane until the advent of the electric start by Kettering. Electric drive vehicles at the turn of the century were considered to be the refined personal transportation of upper class women women, because the crank start of the ICE at the time required a level of activity not considered appropriate, and upper class due the considerable cost of these early vehicles before the age of assembly lines. An often-unsaid attribute of these vehicles, however, was their reliability and robustness, generally better than the contemporary ICE equivalents. 

A vehicle that has two power sources, often a conventional engine together with a battery or fuel cell that provides electric propulsion through an electric motor.

Optimal Specific Impulse of Electric Propulsion Systems (Ion and Plasma Thrusters). Based on relation (11-43) between the initial mass Mq of a spacecraft at low (near-Earth) orbit and its specific impulse /sp, derive formula (11-44) for the optimal value of the specific impulse, /sp Explain why the optimal value of the specific impulse of the ion and plasma thrusters, /sp does not depend on the value of their thrust and is mostly determined by the duration of space flight.

Energy is available in a wide range of forms from our environment, as outlined in Table 1. Conventional energy conversion approaches are well developed at the macroscale to provide electricity, propulsion, heating, or cooling from these sources. A power source can be defined as the combination of an energy source with an... 

There is considerable interest in microspacecraft to support interstellar robotic exploration and near-Earth environment characterization. The principle challenge here is to develop miniature electric propulsion systems capable of operating at much lower power levels than conventional momentum exchange electric propulsion hardware, and which meet the unique mass, power, and size requirements. The Busek Company, Inc. (Natick, MA) [338] has developed held emission cathodes based on CNTs for such an application. These devices have tum-on voltages about an order of magnitude lower than devices that rely on diamond or DEC hlms, and they have shown signihcant promise.

The introduction of the Tesla electric vehicle in 2007 with a 200 + mile range should set the stage for the transition to electric propulsion. The new cathode and anode systems also offer the potential to replace the present lead acid SLI (starting-lighting-ignition) battery on gasoline-powered vehicles.
