Making a simple Savonius wind turbine

by Lance Turner There are many situations where you might need a small amount of electricity, for instance running gate openers, safety lights, water level indicators and other low-power devices. While solar would seem like the ideal solution, quite often this is not possible due to location and shading problems. Just such a situation arose when I decided to make our new gates automatic. Why have automatic gates anyway? Anyway, I decided to provide power to the electric gate openers from a small wind turbine. The gate opener system itself is a home-made job, using car windscreen wiper motors driving long brass threaded shafts. Too much turbulence I briefly thought about what type of turbine I could install and how it would look. This type of vertical axis rotor is very robust and durable if built correctly, is relatively slow turning and can be easily built at home, without the hassles of aerofoil blade design and other problems associated with horizontal axis ‘propeller’ type turbines.

How I built an electricity producing wind turbine Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. One thing I noticed right away about my property is that most of the time, the wind is blowing. Let me state up front that I probably won't be able to help you out much if you decide to build your own wind turbine. Since no one seems to be reading the FAQ, I will answer the No. 1 question I get many, many times a day right here up front. Update: Here is a video of the wind turbine in operation. Update: Here is a video of me assembling and setting up the wind turbine on my remote off-grid property. I started the process of designing my wind turbine by Googling for information on home-built wind turbines. .

index Home Made Wind Turbine Want to build a wind turbine for your home? I have gathered several PDFs for those who want to build there own wind turbines and have links to them at the bottom of this post. They cover all types of wind turbines and issues that you may run in to such as wind speeds and noise. From reading these my self I have found that the Hi-VAWT takes all into consideration and is easy to replicate. In VENTURI horizontal axis Wind Turbines wind turbines the blades rotate and describe a circular surface.

Fermentation Support Forum • View topic - Colonche - fermented prickly pear juice I wasn't sure if this goes here or under tonic ferments. Supposedly colonche is alcoholic, but only mildly so. A friend of mine gave me some prickly pears, but he must have had them in the back of his truck for a week first. I took the best of the bunch, and put them in a bucket of water to soak. I got the bright idea to ferment them into a beverage. Afterwards, I did some Googling, and found there is a traditional fermented beverage, made from prickly pear, called colonche. The method to make it involves juicing the fruit and cooking it way down into a thick syrup -- I imagine to concentrate the sugars. After I read this, after setting a small amount aside, I poured the juice and honey back into the pot, and simmered it down. Once it cooled, I added back the bit that I set aside, and put into a crock, covered with a grain bag. Overnight, it developed a bubbly scum on top: I scooped it off, and by the end of the day, it was back full force. Is this mold or just the yeasts bubbling away?
