Thanks for the reply. I tried to find who makes it, it just takes me to OWS. I didn't try real hard tho.
I had another thought today when looking at OWS catalog. They have a direct drive solar setup. Meaning it doesn't NEED batteries to power it. If the sun is shining, it runs. I'm thinking about getting that pump. Run an alternator and have batteries (which I have some gel cells). That pump claims 2.2 or 2.8 cfm. But it would be consistent. I would need a steady 10mph wind (whatever rpm) to get that with the other pump
I think the alternator idea is a bust Back to thinking the Balcam compressor is the way to go. I think if I adjust the drainpipe output by running 4" or 6" pvc the full length of the pipe plus 6 feet or so. Make it an overshot wheel, which I've seen is more efficient. I have to do more tests, but if I can get 3/4 gps, I think I will be spinning about 60-70 rpm, which should spin the compressor about 100 rpm with a 2:1 pulley setup.
