[aprssig] Generators and LPG Conversion (was APRS in NOLA)

hi keith
hmm i thaught about solar panel ,,but i came back at wind power because of 
the price.
here in eastern canada keith,solar power is not much devleppe or used 
because of the sun time we have and main problem is winter exactly.t this 
site we have great wind in a regular speed ,,not so much varation and always 
west to east most of the time .i could even fix the windcharger at the tower 
itself ,no need of a gyro type of fixation.

i tested a 24 vdc alternateur with a special regulateur that start at 8.2 
vdc to produce and all the way to 14.2 vdc so i would have 2.2 vdc +.

essentialy my problem is the blade now and encore solar here is really 
expensive ,,we have lot of winds

we need 8 to 10 amps for the battery,which are RV batteries the transmitter 
is 30 watts output
we ould even install a timer and during night time it would shutt off and 
recharche the batteries
