The NASA Barrel-Shaped Asymmetrical Capacitor (NACAP) has been extensively tested at NASA
Marshall Space Flight Center and the National Space Science and Technology Center. Trichel pulse
emission was first discovered here. The NACAP is a magnetohydrodynamic device for electric propulsion.
In air it requires no onboard propellant nor any moving parts. No performance was observed in
hard vacuum. The next step shall be optimizing the technology for future applications.
