Wyatt
Wyatt designed and built a plasma cutter with a telescoping rod made of a hafnium, nitrogen and carbon alloy. The rod has a limiter at the end that serves as a cap when the device is disengaged. When engaged, the rod extends as a micro-particle accelerator sends plasma particles through the rod to the limiter, which then sends them back to the magnetic stabiliser at the top end of the handle. The plasma particles continue to cycle in this manner until the unit is disengaged.
The device is powered by utilizing the beta decay of Pd-107 ions as an electron source for the electron capture of Pd-103, thereby producing an electric circuit between two different radioactive isotopes. Because this electron/photon counterflow creates a deficit of electrons (relative to protons) in the core, a massive electrostatic potential is developed and the core attracts lower-energy electrons from the reactor's wiring. The ejection of electrons from the core towards the rim of the reactor produces an electrical cell capable of generating enormous voltage and current.
The thumb print reader on the switch is a biometric feature that renders the device inoperable for all but Wyatt.
