there is a solar powered fan which is commercially available from LEHMANS, a
company which prides itself in being a retro "NONELECTRIC" catalogue company
(located on page 113 in the 1999 catalogue). "on a sunny day, this fan can
move a lot of air (up to 1000 CFM)", says the ad. it sells for 319$ (fan
+solar pannels) which seems a bit much to pay. but i guess that with time
it will pay for itself and has the added advantage that the flow rate
naturally adjusts to the amount of sunlight which is proportional to the
heat generated inside the greenhouse (if the solar pannels are mounted
accordingly).
most amazing is that lehmans, the nonelectric company has a website:
www.lehmans.com . to me, its a strange conundrum.
