Hello all, I joined the group a few days ago, and have spent some time reading the entire message base, as well as looking at the files and links sections and...
Hi Michael -- I can't see why it wouldn't work, but much will depend on how large you are trying to go with your swept area. I'm not sure what a 'chalk wheel...
I just posted some new pics for my windmill. All I lack now is pouring the pedestal and guy wire anchors. Jim C PS They are posted in the Jim622 folder....
Yes they are made of pvc. The reason they are different lingths is because of the materials that I had at hand. I wanted to make them as long as I could. Six...
I got them from a pdf called Poor man's guide to wind power and battery systems. I didn't go directly by their plans for the blades. The book wasn't worth the...
Hello All, I am a new member to this group. I have read about the axial flux Alternator and would like to add it to the new VAWT I have designed. I am in...
They can get inexpensive. I have scrounged just about everything for my windmill, and I still have around $500 in it, and I still don't have it in the air. I...
hi everyone. ive been reading here for some time now and i have changed jobs that allow me to start on my wind mill. at present i live in ohio south east of...
And why wouldn't you expect real help here? Many of use are experienced wind turbine builders, even though this isn't necessarily a wind group. It is an axial...
I'm not in ohio, but the wiring of a axial flux alternator is pretty simple. There are typically 9 coils in a circle. every third one is connected in series,...
I've never used disk drive magnets. The magnets we use are bigger than would fit in most disk drive. I've heard of folks using magnets from microwaves, but...
Thanks for the information. I've just learned that I may have access to a large number of used drives and wondered if there is any interest in the magnets...
Generally, hard disc drive magnets are too small to be of much use except in tiny science-fair type wind turbines. Old, giant computer tape drives (the kind...
This was a very busy weekend for the Green-Trust and Woodhenge teams, as The Science / Discovery Channel film team arrived to do a photo shoot on Wind Turbine...
How does someone figure the number of turns of wire in a coil to get a specific voltage, i plan on using 14 guage wire the target voltage is 8 volts per coil....
I have looked on the Science Discovery channel on Sky but don't see mention of the Green Science series, do you know if it is shown on Sky in the UK? ... -- ...
35 turns (per coil) is 12v per set of 3 coils, 70 turns is 24v, 140 turns is 48 volts. the thickness of the wire determines the amps it can handle before it...
RPM does affect voltage. Which is why with 5 foot blades we are shooting for 650 rpm at 25 mph or so. it will spin at the correct rpm even at lower wind...
