I think have have done enought thoery on the engine, im just starting to build it, the first stage is build a hv cap, second is get the magntics and make the u shaped housen.
The engine is a side path for a submarine that I plan on building, will update the post with more of the theroy docs.
The engine is powered by a electric current throught salt water, with magntics to convert the water to velocity, and then turn a turbine.

Hi Suliaman The pressure of the exhust is so low compared to the surronds that it would be massivly ineffecient. A 30J pulse in 1uS should create enought hydrogen and oxygen to fill a space 1*4*50cm tube in that pulse, if most of it is gas copared to 15psi per ten meter depth.

Would this design work, using just the jet. Trying to make a really smale pipe and accerlate it up fast, the get the surronds to speed up as this goes throught it, thoughs.

Running the thing with a car battery charger, added two more mags, the velocity is about one meter in ten seconds. Below is a module that I think will build, just got to double check some stuff.

I'd expect some 'leakage' current to/through the magnets (outer terminal | fluid | magnet | fluid | inner terminal ) electrical current flowing along magnetic field lines does no work, try insulating the magnets from the liquid, may be more efficient.

Thanks Sulaiman, tryed to insulate the mags, but made less, im guessing the current sleed across the top, make it 90 degree angles. Also tryed useing Ti instead of steel, moving the plates closer made more speed. Im guessing the design is floured, should have the mags in close proxmity to make the path short, and maybe Al and Ti plates as that with both seems to increase the power.
Plan B, following a more well know design
This is the setup from above
This is the second design, It has 4 mags point down then Mild steel directs the field to the left and the other 4 mags point it up.

Tested using more reactive platrs, the source is still a 12v,2amp battery charge, next test will be trying to increase the source power
Messured the resistance of the device and are getting 14.5ohms Below is a 24volt 2amp source
Below is a 36 volt 2 amp source
Below is a 60. 4.5. Volt. Amp throw device, with a 30uF smoothing cap for the ac recifered parts, the resisance of the mhd drive is 14.5 ohms messured by a voltage dividerr. ,R2=10ohm, vin= 12 vout=4.90

Been spending sometime work out a way to get high volts with a high frequency, trying to find a way that will injuice large current throught the water as that has reached a bottle neck. The below circuit is driven from main voltage and frequncy, with a h bridge setup to slice the ac up. For isolation between stages are 30kv 100nf cap network on both plus and minus. The zeners are rated for 10 volt, the transfomers are pulse types with the values taken from the datasheet, one is 50hz 0.8ohm the other 60khz at 80mohm.
The parts for this are quite cheap to muck around building it, in a while should have a prototype built and tested. If anything is wrong with the circuit, wouldn,t mind feedback.
