The first flamethrower utilized a 60,000V ignition system. However, the resulting plasma was highly unstable due to weak magnetic confinement and low current density.
The next iteration operated at approximately 30,000V and employed a resonant cavity, resulting in a significantly more stable and reliable plasma.
The final design utilized two magnets to sandwich the resonant cavity, successfully confining the plasma. The arc spun more vigorously but remained tightly bound, allowing for easier ignition of high-flash-point fuels and reducing heat transfer from the plasma to the magnets.
The first major iteration of the 'Big Boy' flamethrower. While heavy and overbuilt, the design was undeniably unique, blending modern and retro styling.
The second major iteration of the 'Big Boy' flamethrower. It was slightly lighter and featured a more reserved design language, though the assembly and maintenance processes proved somewhat difficult.
The final iteration of the 'Big Boy' flamethrower. This model is approximately 40% lighter than its predecessors, features streamlined assembly and maintenance processes, and delivers nearly twice the operational range
Lithium Chloride Dissolved in Methanol (8-10ft flame)
Pure Gasoline (20-25ft flame)
Pure Diesel (45-55ft flame)
Pure gasoline is too volatile, leading to premature ignition. This issue reduced the maximum effective range and compromised overall safety and reliability by leaving burning fuel trapped inside the igniter.
Using pure diesel allowed for increased range and reduced heat transfer to both the user and the flamethrower, as more of the fuel combusted further downrange. Additionally, due to diesel’s high flash point, the issue of premature ignition was completely resolved.
