Hi Any mechanical device would be expensive and require maintenance, this will limit the scale of deployment.
A more natural source of oxygen like Diatoms would be cheaper and environmental friendly. best regards Bhaskar On May 16, 3:07 pm, Michael Hayes <voglerl...@gmail.com> wrote: > Hi All, > > I have pulled together a few Bubbler Buoy option. > > Here is an Advanced Anchoring and Mooring Study". > > http://www.oregonwave.org/wp-content/uploads/Anchor-and-Mooring-Study... > > <http://www.oregonwave.org/wp-content/uploads/Anchor-and-Mooring-Study...>This > study opened up a few useful bubbler buoy design ideas.
