Hi again, well I may be going to one of those infrequent meetings tomorrow night, it seem that one of the guys has may some in roads with carb varpour and HHO so if there is any thing of interest I will let you know.
as for the 'green' effect no it was copper vaporising, and in the transgression that the water goes though as it dissociates it all happens in less than micro or even a smaller time span the hydrogen and oxygen is ionized and goes into a sharp temperature climb, as more water is put though the unit less power is required, just enough to keep the process going as the water basically after that just keeps getting hotter but is is then in a vaporisation plasma form, as this increases the temperature will reach the critical point and go into full plasm form at 12,000C it is plasma after 3,000C but the forth state of the water does not happen until 12,000C.
at this point the process goes all quiet apart from the compressor. it is uncanny to see it like that as it starts it can crackle pop bang and then it goes silent, watching it like that even for a minuet and a half is wonderful. 600cc a minuet at a loss of 40% of the water and all the combined power used this includes the compressor, still was only 5kW, think was it could do at the full designed rate of 12 to 15 liters a min. with the power around 25kW.
