I thank you kindly for posting that link, it reinforces the theory and sheds new light on aspects that have been kept quiet to date.

I still think what we are seeing here:
YouTube - HHO experiement with horizontal stainless mesh cell
Is perhaps where the answer lies.

I feel the output of this cell, meaning volume, being "injected" into the combustion chamber, then ignited with a Firestorm plug, perhaps delivered by a Nology lead, will see a suitably robust combustion being achieved, with the HHO content as the bonus to keeping it all happening.

Robert Krupa alluded to a phenomena becoming apparent when the stoic level was doubled to 30 to 1, I feel this is where the "secret" lies, and will be realised most, once the metering is correctly set to where that mixture can be held onto. I reason that the low output of a HHO gen, as we are used to seeing, can be "stretched" out to realise this 30 to 1 ratio with careful metering.

There needs to be a suitable injector made, and I think there are a few people playing around with that right now.

I have recently completed a series of tests with standard "J" gap spark plugs, indexed to the best firing positions, and topped off with a comparison to the Brisk HOR15LGS multi firing point plug, the results are interesting as it clearly shows a temperature reduction along the lines of what Robert Krupa alluded to with his Firestorm, although not as extreme as what he achieved, it's still a lot closer to what he managed than what you can get with a standard "J" gapped plug.

This link will get you to where you can see the temperature changes apparent in the indexed standard "J" gapped plugs, as opposed to the Brisk concept plugs.

I believe the current HHO boosters are sufficient for the task, it's just getting the "mixture" right.
