... MIGHT i suggest looking at the old NACA write-ups. Cowlings and nacelles have been found to enhance cooling for radial engines and reduce drag. Of course...

My humblest greetings to everyone. My name is John. I am from Singapore and I have been trying to build my own alternator. Unfortunately, a lot of the parts...
Thanks Steve for the heads up on this device. I am not quite ready for this yet, but will consider it. Steve one Q though Do  U know how much transient is...
Preparing to build first axial flux after having built 4 other type alternators will poor performance (cogging, low output etc) Please comment on my planned...
The Axial Flux, and any other wind turbine, can create enough electric to cut your electric bill substantially. Why is it that most people stop at ONE? If you...
If you consider the higher efficiency, would it be worth going with silver, silver coated copper, gold or gold coated silver to increase efficiency of...
Gold makes good contact material, but these units do not have contacts. I don't have gold wire to test, but something tells me it won't generate much of a...
The tower costs more than the turbine, but it is good to have at least two, in case one is down for maintenance. I have two solar arrays, two generators, two...
1. Did you try to use rectangula (not round shape)Â shape wire wound for increase efficiency of Alternator coils? 2. Did you try to use more stronger...
Hi Harold and All, Silver wire will be more eff and allow you to have more turns if you want but better magnets would cost less, allowing thicker copper of...
... Silver is only a slightly better electrical conductor than copper, and it oxidizes faster, requiring better sealing from air. Gold is not a very good...
This past spring, I built a 24 volt 8 foot axial flux system, exactly to the specs in Hugh Piggotts plans in his book (it works fine). This spring, I'd like...
Hey Charlie other power dose have a book out now. You can buy it on thier website I have the book and it goes in to great detail on every aspect of building...
Hi Charlie -- our new book "Homebrew Wind Power" will be shipping Friday. You can get it from the products page on Otherpower.com (it won't go up until the...
How is the best way to test the voltage that is developed on a single coil? I want to test various configurations of coils and magnets but need direction for...
wire up your coil pack (3 coils in each series set), and rotate the magnets at the speed you expect. you will need the rectifier wired in if you want to see...
An oscilloscope will give you the AC results. Some software (freeware) o'scopes hook to a sound card input (voltage divider needed). A DMM might be hard to...
Check out Swiger coils website. They use silver bearing wire for power generation and have about 700 varieties for sale. I'd like to use their wire for my...
... (freeware) o'scopes hook to a sound card input (voltage divider needed). A DMM might be hard to read, or inaccurate, depending on response time of the...
It isn't more efficient at collecting the magnetic field lines but has lower resistance and therefore a lower I squared R loss.  On my generator it would...
saved energy is measured in delivered units/time for example watt hours. Commercially we buy power in kilowatt hours. The difference in efficiency would be...
