H₂EM-Field Propulsion A New Class of Space Propulsion Engine Author: Wayne Griffiths, AEMS LLC / Griffiths Canon Research Group Living Document — Updated as validation programme progresses We have developed a propulsion architecture that uses electromagnetic fields to govern hydrogen plasma exhaust — the same way the Earth's magnetic field has governed plasma for 4.5 billion years. The result is a rocket engine with far higher fuel efficiency than anything flying today, combined with a propellant delivery system that solves the deep-space fuel problem in a way no other architecture has: we don't launch the fuel from the ground. The Problem Nobody Has Solved Every rocket flying today faces the same fundamental trade-off. Chemical rockets are powerful enough to lift off the ground but burn through fuel so fast that most of the rocket's weight at launch is propellant. For a crewed mission to Jupiter, you'd need to carry 80–90% of your launch weight as fuel. That leaves almost nothing for the actual payload. Electric propulsion systems like ion engines solve the fuel efficiency problem but create a different one: they produce almost no thrust. You can't launch on an ion engine. You can't even manoeuvre quickly in an emergency. They're only useful in the vacuum of deep space, and even there, they're too slow for crewed missions. Nobody has bridged that gap. No engine today is both powerful enough to be useful and efficient enough to make deep-space missions practical. NASA's own P
