Buffer, there are several good mill producers however some of them need to improve in their diffuser technology.In your search consider also questioning the "Lifting Rate" of the dffusers. If you can not obtain the independent lifting data you may want to search for seperate diffusers for your project. I would search for high volume diffusers that can lift no less that 3200 gpm @ 10 ft depth or 4500 gpm @ 16 ft @ 2 cfm. If you can locate a mill that produces at least 4 plus cfm at 10-15 psi or less that may be a contender.The weak link in many windmills today seems to be diffusers. Hopefully manufacturers in the near future will discover this shortfall.
