From our Webster's Unabridged Dictionary: "synchoresis . . . in rhetoric, a concession allowed, in order to make a more pointed retort." Keep synchoresis in mind as you read the following pages. The warnings I give about homemade electricity generation serve several purposes. They remind us to be careful in specific ways as well as displaying that we are aware of the dangers. Engineering, installing, and testing electrical systems require that we take responsibility to test and design devices that can function in the real world, with real people, real weather conditions, and within predictable scenarios.

The above photo shows two of my wind turbine experiments. Details on how I built them are posted in my Journal Archives and some day I will have videos to show my turbines spinning. Their materials take advantage of my desire to recycle gallon plastic water jugs. I cut the jugs in half, to start, to take advantage of the strength of the neck of the bottle on one half, and the strength of the handle from the other half of the bottle. I then hung various configurations from a camera tripod, with fishing leader, line, and a swivel in front of a cold air return located at the base of a wall in our dinning room to observe how well a little bit of air movement could make them spin. These whirligigs now hang from various locations around our house so I can observe how much wind we actually have to power future electricity generators.
I learned that most fishing swivels don't work as well as I would like them to, but the SAMPO
brand out of New Jersey uses actual ball bearings inside the swivels and work wonderfully well. You can order these from Cabellas, Bass Pro Shops and many other fishing gear catalogs. I ordered the hollow plastic quarter-hoops from the www.orientaltrading.com
website. You can get 50 quarter-hoops that assemble into 12 and a half hoops. (BTW, Wacky Noodle hollow foam toys fit over the hoops and I am currently -- 6/28/10 -- investigating the Wacky Noodles as insulation/support for wire windings. Perhaps I could sew the wire windings onto the Wacky Noodles?)
The taller turbine in the above photo has a hollow plastic flag pole with aluminum wire attaching the water jug halves. I two skewers to attach the hoop at the bottom, and the hoop is filled with high-powered magnetic marbles I purchased from K & J Magnetics,
plus homemade spacers. (BTW, I replaced the plastic flagpole (6/28/10) with a 1 1/2" thin-walled PVC pipe.) The skewers -- it turned out after a few weeks -- bent/sagged over time, so I am replacing them with a different material such as those green plastic tomato plant stakes I see in gardening and hardware stores, Ultomato.

In the photos below the "half bottles" are actually quarter bottles because I cut off their bottoms. I decided to avoid the retention of rainwater and snow, you see, but the "half bottle" concept comes from dividing gallon jugs into halves that contain either bottle necks or bottle handles. Here is yesterday's photo of the "Handle half-bottle" or "Handle quarter-bottle," rather, whirligig with hoop, followed by "Neck quarter-bottles" whirligig with hoop.
This website is intended as a web log or blog, so should be continuously added to and/or changed, even after it is finally set up.
Handle Quarters, again:

And again. Maybe I'll get it right this time....
Journal Archives are growing! Check out the deer fawn on the Journal Archive 0 page. I am displaying blog entries from the past not only for people who were not members of Blogit when I originally posted them to my blogs, but also to help me find the links that I provided for finding research and trains of thought that I intend to follow up on in the future.
