High-temperature electrolysis of steam

Microwave-powered sulphur lamps also get very hot. The plasma created inside emits light...I wonder if a flow of water vapour on the bulb could be enough to break down the water molecules.But anyway, it would be hard to seperate both gases created. They would end up combining again into water, a bit like when a very high voltage is applied to water. the water explodes releasing hydrogen and oxygen but are quick to recombine.

I posted a question on Yahoo!Answers but failed to get a decent answer. Can anybody tell me what would be the effect of immersing the antenna of a magnetron in water?

Imagine a JoeCell. Now imagine putting the magnetron antenna in the centre of the cell. There is some japanese guy who used a JoeCell to sucessfully make hydrogen, but not much though.

Microwaves being simple radiowaves, excite susceptible molecules such as water it is placed in a microwave oven cavity. But the water in the microwave oven has no electrical connection to the ground and the microwaves, which are reflected by the oven walls, have nowhere to go except on its 'target'. Whereas in a cell such as the JoeCell, the water is electrically connected to the ground.

What do you think would happen? Would a current be created?

Kevin, do you think that tungsten would be able to sustain a thermal shock such as having vapourized water going on hot tungsten wire?
