Hmm, I just notice a mistake here (in GoatGuy's post he did 1.03g/s * 12.7 m/s = 13.1N) : 1.03g/s * 12.7 m/s = 0.00103kg/s*12.7m/s= 0.0131N. You forgot to convert to SI, which is based on kg, not on grams. That's the typical force and speed of the the wind of when you blow a candle on a cake. That force you obtained is typical of pressures during supersonic wind tunnel simulations, that is, 2 psi. This like the blow of a 1kton atomic explosion 600 meters away from the explosion, at sea level. 2 psi is also in the range of severe to total damage in atomic explosions...
http://en.wikipedia.org/wiki/File:Blastcurves_psi.svg I made some very strong blows, and tried to measure the speed. It clearly diminishes to much less than 1.0 m/s after 20 cm, and it scatters very strongly after 4 cm, when I keep my mouth opened as that hose. The average speed is like the one you said, something around 0.8m/s. As far as the current is ok, but if it is nuclear, it is useless as an energy source if just by the vapor blow. 2500Watts are just converted to around 2*10^(-3)*(15 ^2)/2=0.225W. So, you'd need more than 1000 e-cats to feed 1 e-cat. The only way to make this work is make the gas to go up, but I am afraid it wouldn't go up too much. Maybe by heating another gas? So, at least I am, back to see only if there is any hidden energy source or clever manipulation. For me, there is enough proof that exhaust output is OK, humidity is OK. So, I retract part of my skepticism...
