Editing Pulsed plasma thruster (section)

== Advantages and disadvantages ==
PPTs are very robust due to their inherently simple design (relative to other electric spacecraft propulsion techniques). As an electric propulsion system, PPTs benefit from reduced fuel consumption compared to traditional chemical rockets, reducing launch mass and therefore launch costs, as well as high specific impulse improving performance.<ref name = NASAPPT/>

However, due to energy losses caused by late time ablation and rapid [[conductive heat transfer]] from the propellant to the rest of the spacecraft, propulsive efficiency (kinetic energy of exhaust / total energy used) is very low compared to other forms of electric propulsion, at around just 10%.
