Double-Fed Induction Linear Alternator
This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...

Improved Directed Flux Motor
Electromagnetic motors typically convert electrical energy into rotational mechanical energy and are employed across a wide array of applications. While motors represent relatively mature technology, practitioners continue to seek ways to enhance motor operation including a decrease in cost, drop in size/weight,...

Green Electric Monopropellant (GEM)-Fueled Pulsed Plasma Thruster
NASA required a rocket thruster able to produce a number of pulses at high specific impulse at a relatively low voltage (~300 to 400V). The key problem was that existing propellants for liquid-fueled pulsed plasma thrusters (LPPTs) required high voltages to ablate and accelerate...
