12v Fans for ports
You might want to run a yahoo search on KISS wind generators...because you should get a link to "Hotwire"...they are in St. Pete FL area and besides the KISS wind generators they sell a port mounted small computer power supply kind of fan that moves quite a bit of air. I saw these fans at the St. Pete Boat Show recently and they do move a pretty good bit of air. Send an email to them - address it to "Libby".
If you can''t find a link to them, email me at Rob@Mainsheet.zzn.com and I''ll hunt up the email address for you.
