After a nights sleep and with regard to this video....

Hi Graham
I'm 99% certain that the engine is running on a mixture of " atomised " Petrol and water closely related to the PDF pictures I posted a couple of pages back.
I have watched the video about 10 times now,and in full screen.
The video is of low quality,and some things are hard to make out .
But what i do know is that the electronics board they showed(which i identified)is only a 5 volt board,and not 24 volts as they claim. It is also just a DC power supply,and is not an ultrasonic driver board.
It also has a power output rating of only 5 watts,which is also not enough to drive an ultrasonic unit.
Brad has also mentioned that Petrol " mists " just as easily as water using a " fogger " and as it floats upon the water the two will be carried into the combustion chamber.
Yes,i did say that the fogger unit will atomise gasoline--no problem there.
What i do not know is what will happen when both water and gasoline are placed in the fogger unit,as i have not tried it yet. I believe that the water will not be atomised until the gasoline has been depleted,so the two will not atomise together. But we will know for sure by tomorrow evening
I'm wondering, like Brad, if the engine hasn't got the strength to " pull the skin off a rice pudding " ? A load applied would verify this aspect.
Im smelling a rat with this one.
So far we know what the electronic board is,and it is not what they say it is--strike 1
Then,after watching the video many times,it seems to me that there manual air inlet valve(the chopped up T piece) seems to be closed while running the second test--strike 2
And as you know,i spent a fair bit of time making the gasoline vapour setup i tested,and even using gate valves that could be very finely adjusted,it still took me a good 10 minutes to get the mixture just right,so as the motor would run quite smooth. This guy is twisting a very !non accurate! valve (the cut away T piece),and his engine starts right up,and runs very smooth. So thats is a strike 3 for me.
Now,the pipe plumbing they have going on there dose not make much sense to me.
To the average joe,it may look like it should,but i wonder if anyone will see/note what i did about that maze of PVC pipes and boxes. Strike 4 for me there.
And then there is the watt meter showing 282mA.
The bloke in the video says that particular unit uses 282mA @ 24v.
But,that watt meter is plugged into mains,not 24 volts,and so is using 282mA @ 110v(assuming it's in America)
That is 31 watts of power,and not 6.76 watts as he claims.= strike 5.
So either he is being very deceptive,or there is something else going on there some where.
Things are just not adding up here.
Following muDped's link posted this morning it was pointed out that " flash steam " if admitted into a cold cylinder can actually condense so quickly as to be ineffective. I'm wondering if that is what was happening in the video where the demonstrator needed help to readjust the settings, presumably the engine was warming up?
Well you would be the man to answer this one Graham,as im guessing that you must have had something to do with steam engines in the past ?
What happens when you inject steam into a cold cylinder?.
I would think that when you inject water vapour into a volume of hot air,that is some what close to 500-600*C,it would turn to steam. The pressure would increase,and push the piston down.As the piston is pushed down the bore,and the pressure drops rapidly,the steam would once again condense to water droplets,but i would think that would be after it provided useful work. I don't know,as i have not made it that far yet.
A " busmen's " holiday awaits, eh Brad? 
Not sure what you mean there Grum ?.
Are you referring to the big bus trip H2G are taking all those people on ?.
