Re: [EE]:: Operation of water pumps from Wind Turbines

Yes, if you inject air bubbles into the water you will reduce its density 
and induce a flow moving upwards.

If you inject air into the outlet of a pump (above the pump) you will 
reduce the density and increase the "head" for a given weight. Also the 
air in the water is compressable which might help a pump start at lower 
power.
