Project Resources

What informed the build

Development draws from pulsed-power references, plasma and discharge literature, CO₂ conversion work, and safety/standards guidance.

Technical areas

HV pulsed power Pulse shaping & protection Discharge physics CO₂ conversion Non-equilibrium plasma Gas-flow control Safety standards

The current project stage prioritizes a defendable prototype and repeatable measurements rather than broad performance claims.

Current documentation focus

  • Clear separation between overview content and technical development content
  • Accurate wording around preliminary results and current limitations
  • Team-produced figures, diagrams, and build photos used across the site
  • References grouped by current pulsed-discharge work, safety, and earlier background
