I know that you have many "fans" here that do appreciate your line of thought.

Chet, the trick is to get at the truth.

Isn't your hypothesis that you can perfom more work than energy you input by plumbing your apparatus to the local environment?

As clearly stated in the video,the video was to show effect,not efficiency of the system.

If that is what you are trying to get to, then the experiment design effort should try and falsify that as directly and simply as possible.

Try and falsify?. How would one do that when it can be seen as clear as day?. That would be like me trying to show that a 12 volt battery really dosnt have 12 volts across it's terminals.

Changing a variable and noting that the fan speeds only tells us that more power was imparted to the fan blades.  Since that can occur for several reasons, it does not tellwhich of those reasons or combinations of those reasons.

This is why i suggested the mass acceleration test. Would you not agree that to accelerate a mass to a higher speed over a set distance requires more energy ?.
I can remove the nozzel from the venturi,and point that at the fan blade so as it's in the very same position it was when housed in the venturi,and see what the outcome is-->but of course,i have already done this,and can tell you the results are exactly as they are when the nozzel is housed in the venturi.

If you would like to put forth a test setup Mark,i would be more than happy to try it out.

This demonstrates nothing other than a more efficient nozzle. 
Since you are not actually measuring the energy potential of the source you can't make any pronouncement at all that an energy gain has occurred.

Try the same experiment without a venturi but simply vary the nozzle shape and diameter.You'll find exactly the same effect occurring. A nozzle that can generate a higher velocity flow will produce more lift on the fan and hence more output to the generator.

Sure LE.
We can also bore out an engine,put a set of high flow high compression heads on it,and say we now have more HP for nothing-->forgetting the fact that it now consumes more fuel to gain that extra HP.
We can reshape,change diameters of the nozzel to what ever shape you want,and then get the maximum efficiency. If we then take that same nozzel and place it in a venturi setup such as the one i showed,the fan would still spin faster.

The problem here is you are not measuring the 'fuel consumption'. Consider the air hose is supplied by a compressed tank that and the air exits out various shaped nozzles. Obviously the time take to empty the tank would be dependent on the size and design of the nozzle. The amount of 'fuel' would be constant but the total energy generated by would be dependent on runtime and the efficiency of the conversion performed by fan.

Measuring instantaneous power is not sufficient to claim an ENERGY increase.

Also, once you have exhausted the tank you then need to recompress the tank. Did you create enough stored potential to do that.? I can tell you for certain that you never can, no matter how efficient your nozzle is or whether it contains a venturi or not.

None of this of course precludes you from finding and environmentally supplied source of heat and a corresponding environmental sink at a lower temperature and devising a heat engine that operates between those two reservoirs.
