US Patent 9169814 Systems, methods, and devices with enhanced lorentz thrust

Methods, systems, and devices are disclosed for delivery a fluidic substance using Lorentz forces. In one aspect, a method to accelerate particles into a chamber includes distributing a fluidic substance between electrodes configured at a location proximate a chamber, in which electrodes include a low work function material, generating a current of ionized particles by applying an electric field between the electrodes to ionize at least some of the fluidic substance, and producing a Lorentz force to accelerate the ionized particles into the chamber. In some implementations, the method further includes applying an electric potential on an antenna electrode interfaced at the port to induce a corona discharge into the chamber, in which the corona discharge ignites the ionized particles within the chamber.
