June 6, 2010: Recent Activities
I tore down a motor that was left over from our dishwasher after it was replaced due to a cracked PTO, in the hopes that I could use the wire windings to build an electric generator. I am faced with hack-sawing some thick, laminated electromagnetic material and I don't think I'll go to all that trouble. The reason I was considering hacking my way through it -- on two sides in order to get to the wire -- was because the price for laquered wire is so high.
I remember, now, I was previously considering how I might coat wire in order to avoid the high cost of "magnet wire" -- and even considering coating aluminum wire for the same reason. Perhaps I'll go back to that idea.
Also, I found a Lakewood Kool Operator fan (22") to be a perfect size on which to mount the wire windings that I would place under my tall wind turbine. However, I am also going back to a previous idea of taking an old tire from some tractor for mounting the wire windings so that I could get some measure of protection from the weather as well as insulation attributes from the old tire.
Soon I'll be "dumpster diving" again, I hope, near a business that sells and repairs lawn tractors and ATV's. I got one tire, earlier, from the dumpster of a bike shop, but it is too thin to have more than one over-exposed layer of wires mounted on it. I could get two layers -- top and bottom -- inside a tractor tire.
I know that tires are ugly and are unhealthy because mosquitos can breed in them if you don't alter them to drain rainwater, but a coat of white spray paint might help on the outside, with holes on the bottom layer of the tire. Recycling tires is the least expensive way to go, I think, and that is important -- especially on my non-budget, lol.
Safety and productivity are first on my list of design considerations. Practicality and economy are broader terms for the same concerns for safety and productivity. Electricity generation requires knowledge of safety precautions because if your system is not "robust" -- that is, if the design doesn't take into account all the many ways the design could fail in the real world -- then the design may be worse than useless, for it could cause a fire and the whole house could go up in flames, God forbid (knock wood).
As I read in one book, your gizmo could still be producing electricity while it is damaged, and we can all imagine what excess electricity looks like when we think of lightening.... So, getting a grasp of electrical safety is a must. That is why I have created a separate page for Safety that will focus attention on this concern even though much of its information will be repeated from other pages.
