lol...funny...
no the point being it does not take a large amount of power to lift the water to the top..given there is over 1,000,000 sq.ft of area at the top opening of the tower it would obviously take more than a few pressure washers to do the trick....but the reality is your not trying to create a water fall to turn the blades which would use as much power to pump up as falling water would create. Add friction and and mechanical efficiency % and you have a perpetual motion.....but in this design it is only a Air fall that is created.....the added energy is from the sun which warms and dries the air..
cold air sinks hot air rises, cold wet heavy air inside cylinder goes down.... your contention was that you can't make the air flow down....your wrong.....now up here in western Washington where I live it would not work well because our air is cool and usually close to dew point, so the air has little or no capacity to absorb water and the air the surrounds the tower would weigh as much as the air inside the tower so the air would be stagnant
remember if you drop a bowling ball and a marble of a tower they will fall at the same speed through the air and have the same terminal velocity, since there shape and air drag are about the same....
the falling air has no air drag, since the mass of air as a whole is falling....only the drag would be along the tower sides and at the bottom the drag of the fan blades
