Jed, The JLN's MAHD does NOT disassociate water! The water is merely a cooling medium for the anode.
The heat in the MAHD is generated in a gaseous hydrogen at 0.1atm pressure between inner heated cathode and outer cold anode. This is essentially a vacuum tube, but without electrical HV polarization between cathode and anode. The MAHD cathode is a tungsten mesh heated with a low voltage and high current pulses (>100 Amps) at low duty cycle (5% seems to yield the best results) at 50Hz. It is claimed that these short >100Amp pulses resistively heat the tungsten cathode to 3000K (periodically) and thermo-disassociate molecular hydrogen into atomic hydrogen in its proximity . This heating and thermo-disassociation of the hydrogen (H2 -> 2H2) costs energy and represents an energy input to the MAHD. When the atomic hydrogen exothermically recombines into molecular hydrogen (2H -> H2) further away from the heated tungsten inner cathode (but closer to the outer anode cooled by water), it releases the heat of recombination to the outer anode and subsequently to the cooling medium (water in this case). The hydrogen also exothermically recombines between the heating pulses. The heat of hydrogen recombination represents energy output out of the MAHD. JLN measurements indicate that Thermal Energy Output divided by Electrical Energy Input is > 1 and in some cases > 20.
