Lets write some articles for the FAQs Section
« on: May 25, 2008, 10:24:35 PM »
I think that the FAQs area could use some more content, and maybe we could all contribute to writing some new articles for it. I was thinking that we could take on a new question every week or so. I will present the questions that need to be worked on and we can all make comments that give new users good information to get them started good. Then I will consolidate all the information into a FAQ on the subject that we can agree on.


So ,  What exactly are the Frequently Asked Questions ?

I can think of a few but there are many more that you guys could help me remember.

 What about 2 or more smaller turbines instead of one big one ?

 Can I use 2 stators between 3 magnet rotors ?

 Is this motor good for making power ?

 Can I use 2 props on the same wind genny ?

Which ones can you remember . . .


Now lets get started. I wrote a FAQ last month asking "How can I get the longest life from my batteries?". I thought I did a pretty good job on the article but later I realized that I didn't say anything about keeping the plates covered or what kind of water to use to refill the batteries. You can review the article here

http://www.fieldlines.com/story/2008/4/22/142649/842

and leave comments in this thread about what I can add to that FAQ.

I will then edit the battery FAQ until it has all the information you guys contribute. Keep in mind that this information needs to be written for a Newbie and should only contain the most essential facts.

put together an outline or a flowchart, then populate it with topics

for folks to right articles to.


that is how i would do it :)


fer instance


1. batteries types

  a. flooded lead acid

  b. vrla

  c. nickel cad

  d. edison cells


2. battery charging

  a. charging regimes

  b. charger types

  c.


3. alternator/generator types

  a. wound field

  b. brake drum pm

  c. axial disc pm

  d. motor conversions


4. wind charger blades types

  a. vertical machines

  b. horizontal machines

  c. other


5. blade manufacture

  a. pvc

  b. carved wooden blades

  c. etc



  1. etc.
  2. etc.


...


this sort of thing, so that it is easy to follow, and gives folks that have info

an indication where what they have might fit in and be of use.


just a thought

Hi Woofer,


Great idea.


Not long ago, I set about putting my thoughts together about what I had learned about PMG's (mostly from this site).  What started as a list of features turned into a "white paper" on the axial flug alternator.  Perhaps it can serve as a FAQ, or sew the seed for something else.


The old file seems to be corrupt on the server, here.  I'll upload a fresh copy and you tell me if it would help.  It's currently in PDF format, but if you want, I can just give you the original image and text files.  I will post a link when I get it uploaded again.


I also have a few things I could say about towers:  it's a tightrope walk, telling people what does and doesn't work, yet not being overly encouraging, lest someone go out and do something unsafe.

Excellent idea Wooferhound and Bob G.


Simple stuff such as batteries - types, how to wire in series, parallel, and mixed parallel and series, battery maintenance equipment i.e. DMM, analogue meter, SG measurements. What should should check for at the moment of purchasing batteries.

Fork lift truck batteries, telephone exchange batteries,the whole gammut as basic information would be useful for new and seasoned people on this site and save much repetition.


A sort of basic ready reference base that would not neet to be frequently updated once its assembled.


Problem is it could be work for those who may not want it.

     If I understand, although you ask where to start you have decided on Batteries and the discussion here is then what basic facts should be included in a battery FAQ. A logical choice because batteries are probably the most common denominator except for wire. Or do I have it backward and this thread is for topics, and battery stuff goes in the thread you linked?


     Anyway, my input then from a newcomers point of view will be a question. I have read many times about how important it is not to draw the battery voltage down too low, 12.2 is often mentioned, but is this load or no load conditions? I can be running something off my bank and see the voltage under load drop down below 12 volts but as soon as I disconnect the load, in just 30 seconds or so the voltage is back above 12.2

     So I think a good FAQ would be how to measure this low voltage threshold assuming your inverter doesn't do it for you. Sorry if it was already covered.


Good luck Woof and thanks for taking the time for this.

A Great Idea Woofer.


I think that it should be to send the beginners for 'easy to follow steps' for whatever they are trying to do. The questions already asked are a good place to start for addressing a beginner's needs.

Yes, I have seen your excellent PDF before.

I was planning to write a FAQ called "Read This First" that has most of the information contained in that file. It would be more elementary tho so as not to overwhelm the newbies. But your PDF should be linked in the article for the more serious beginners.


That will be the next FAQ that we will work on.

Thats a good one even though it's not actually a Frequently asked Question

more like a frequently uninformed Posting.


Very much like the "I am making my stator from aluminum" style uninformed post.

If you send me an e-mail, I can replay with the image files and text.  Edit as you please, I don't claim ownership on the document seeing how I copied many of the images from this site, and the text relies heavily on postings on this forum, too.

If you don't want to claim ownership, I will!

(that's a joke)


I am beginng to see the newbie FAQ as 3 levels...

Knows nothing, not even the terms

Knows enough to ask decent questions.

Knows a little more than that.


"Deep" papers are too much, overwhelming.

FEMM stuff is confusing even if the very basics are understood.

Bridges and fets can be too much for someone who made a 10' mill on an 80' tower, from scratch.


FAQs is a huge task.

I'll answer your question here

A battery will give you 3 different readings depending on how it is being used at the time you take the reading . . .

 High when being charged

 Medium when at rest

 Low when being loaded

I have seen an excellent chart showing what the voltage should read for all of these readings but after 30 minutes I couldn't find it.

maybe an outline of the various topics, with supporting articles written under each topic,, "with" links to information that is perhaps more deeply explained.


i like ghurds thinking in re to a multi tier


maybe the topics could have a simple writeup that a true newbie could make some sense of, followed by a group of links to elementary explanations, then follow with some intermediate article with intermediate level links, then cap it with some higher level article and links to support that level.


it would take a bit to set up, but there are many good folks on here, each chipping away at their favorite topic,, probably wouldn't take to long to see a real resource emerge in my opinion.


i know we all have favorite topics and area's of interest, along with dozens if not hundreds of links to all sort of info, from manufactures to white papers, diy'er reports to research center reports etc.


personally i think it would be worth the effort :)


i am working on an index of info from my own collection, nothing irritates me more than to come up with a question that i know i have the infomation on but can't remember which book, link or whatever the answer is located in or at.


at least i know the answer is in my collection, to a newbie they don't even have that.

A glossary of abbreviations would be nice. I have 5 Harbor Freight 45 watt solar kits, but it took me a while to realize that's "HF" used in a couple of posts.


I live in an urban area so I can't put up a wind turbine big enough to do any good, but it would still be nice to know the difference between a VAWT and an HAWT. Actually an egg beater turbine might not be noticed, since it doesn't look like a "windmill."

The best introduction to batteries (lead-acid) I have seen in years of research has been the Home Power magazine article from August/Sept 1993.  It has typical charging and discharging charts, where you can estimate the appropriate voltage based on the amount of current, in proportion to the size of the battery bank.

If the charts sound daunting at first, read the article and then it will make sense.


I think I got it from the Home Power magazine website's archive.  If it can't be found there, anyone who wants me to e-mail the PDF, just drop me a line.


It would also make a good addition to the links in this site's FAQ's.

I'd like to see a "Results" section.  Like, in this is what I did, and this is how it performed.  It could be broken down into subsections such as Alternators, Blade Assemblies, Towers, Controllers, Dumps, ect.  This site is, after all, supposedly geared to actual projects.


Obviously, this would require clearer thinking than is usually exhibited here.  And if I'm sounding cranky, it's because I am.  I getting tired of the stupid mistakes.  Unities for units?  My Gawd!

Hey, whadya think the Diaries section is for?  We love showing off our stuff.


If you think you're in a cranky mood, type whatever you want, then delete the message instead of posting it.  I find it helpful sometimes, just to get myself in the right frame of mind.  It's all just a bunch of light and dark glowing points on an electron gun, anyway.

Woof ;

 I think this is a great idea !! Possibly use the tier system for the very basic stuff, then once basics are done move to higher complexity concerns.


One I would love to see at the top would be Ohm's law.


As important as the batteries are, even the people I help around my neighborhood still needed the very basic idea of Ohm's law so they wouldn't be deluded into what someone else ( salesman) told them.


Just a thought.

Sounds like a GREAT idea Woof.  Improving the FAQ section should reduce the number of redundant beginner questions in the Newbie section. And if someone asks one of these simple, common FAQ , then we can just direct them to the appropriate section.


I appreciate what you did with the Battery FAQ.  That should help a lot for new ones to do research and answer their own question(s) most of the time.

Why is 3 blades on a prop popular? I've seen 2,4,5,& 6.

What is stall?

What is TSR, and how would changing it affect my wind-gen?

Why 3-phase? Ive seen one-ph, and 7-ph somewhere.

What are the benefits and drawbacks of connecting my stator coil configuration in Star/Wye, or Delta?

What are the benefits and drawbacks of 12, 24, and 48-volts?

Whats a dump load, and do I need one?

What is furling? How does it work, and why is it important?

What is cogging?


Ummmmm...

Great idea! As a newbie these are some of the questions and thoughts I had when I first encountered this site. I have since found the answer to most (lots of good reading)


·    Suggested reading list (found lots of suggestions here and there but a one stop list would be pretty cool)

·    Simple wiring diagrams of things like, How to wire an 8-wire stepper to charge batteries (I've seen 5 and 6 wire examples but no 8 wire)

·    formula's, Best ways to take meaningful multi-meter readings, Ohm's law and other short answer type of stuff. (Yep, its all here just got to read and find it)

·    Pictures/diagrams of topic at hand (some of us need more help than others!)

·    Explanations of symbols used in diagrams (i.e. the arrow in the diode symbol means that the band goes on this side of the circuit. yes I soldered a 1N4001 in backwards on my first attempt)

·    When using a small DC motor as a wind generator is there any rule of thumb regarding matching shaft diameter and. prop size/weight? And does having a bearing/bushing have any effect other than longevity


Would it make sense to have a "please read this before posting" section? To cover the aluminum rotor,... can I get a patent,.... perpetual motion.. etc, etc type of questions. It would give them/us/newbies a place to debunk any preconceived myths we have running around in our heads


I am slowly getting out of the "Don't not even know,... what I don't know" stage in this sickness and am progressing to the "Knows enough to hush up and read" level. Maybe one day I'll get to the "Knows enough to ask decent questions" but until then I'll be having way too much fun lighting a handful of LED's and charging a bunch of 6 volt, 9 amp hr SLA batteries to run my TV at night. I haven't had this much fun since I was a kid!!! Hope they never impose that "sin tax" ;O)

Unfortunately, those light and dark glowing points enter peoples minds and can cause no end of confusion.  You are skewering the messenger and ignoring the message.  In any case I probably should have let it go, as it detracted from the important part of the comment, namely the proposed "Results" Section.
