A deep-space probe's emergency power recovery systems are being evaluated. Engineers are comparing two methods of auxiliary energy storage to support the scientific instrumentation during a main reactor outage:

System P (Pneumatic Storage): Compressing gas in high-pressure tanks.
- Energy stored per $kg50\text{ kg}$ of system mass = $kJ18,400\text{ kJ}$
- Percentage of stored energy dissipated as heat (wasted) = $32%32\%$
System Q (Electrochemical Storage): Charging high-density lithium-sulfur batteries.
- Energy stored per $kg50\text{ kg}$ of system mass = $kJ24,500\text{ kJ}$
- Percentage of stored energy lost due to internal resistance (wasted) = $18%18\%$

Calculate the difference in the useful energy retrieved (in $kJ\text{kJ}$ ) from $kg50\text{ kg}$ of storage mass between System Q and System P.
