- One power source could be used to power multiple craft (serially, not at the same time).
- The power source could use solar energy, resulting in additional cost savings.
- Plasma propellants are accelerated to speeds an order of magnitude greater than those achieved by chemical rocket propellants, resulting in higher spacecraft velocities - at least 26,000 miles per hour.
