You mention that the plugs often fail. Could this be due to clogging of the spark gap by particles of nickel metal that get melted by the intense heat of the spark? I assume that an engineering solution to this problem will come soon once identified.
If I recall DGT has suggested that their process does not rely upon heat directly to control the energy output. A question was asked about the effects of the magnetic field associated with the drive current flow and they stated that they did not wish to answer that until later. That response leads me to believe that the magnetic field modulates the heat generation mechanism in some manner.

I did not even know what a glow plug is, I must admit. It is used to start a diesel engine. I think Terry is right and the photo shows a spark plug. People who were there told me it is a spark plug. They also said Defkalion is having trouble because the spark plugs often fail. - Jed
