Firedome, I agree with the conservation. My family has been collecting and recycling since the 70s (I have a scar or two to prove it), waste is not something I like to see for anything. As Moores auto said, when more do it the price will come down, and the price won't come down by "nudging" people into it, it has to physically become more efficient to justify, which is my whole problem with all of it right now. Solar cells were in the 12-14percent efficiency scale back in the 70s, and I think they are in the 22percent range now. There isn't any real incentive to get any better efficiency at this point, I would hope and think that something in the 50-60percent range would be more realistic, and government subsidies and payoffs isn't the answer to increase the use, it just spreads the wealth around, the government has never produced one single job and efficiency always decreases when they get involved, as there is no incentive to actually make the improvement because the money dries up if the company becomes sucessful, right? Get the government out of this sector, offer an efficiency award for inventing an affordable and useful alternative means of powering existing systems and go from there. I say existing systems because it does nobody any good to invent an energy source/system if you have to buy the car or appliances to go with the power source, normal phase-ins of something more advanced is one thing, replace one thing with another does not work with the government involved. Example is the removal and natural replacement of records with CDs and Ipods, cell phone and mobile internet systems, all developed by the private sector, not the government.

Roger brings up a good point.  If I am going to just wind for now, I can use a tie inverter and feed back to the grid.  All my excess will spin the meter backwards, which will actually drop my electric bill.  But that is dependant on the wind gusts and charged batteries. 
 
I'll have my wind generators a good 50 feet above ground.  When I look at the trees sometimes, I can see them moving high, but not down at ground level.  Humidity is not a good thing for these though.  It appears you need more wind on the humid days than on dryer days to spin them.  The wind seems to be always moving, pretty much 24/7  I'd be happy with an average 3 MPH like that.  But higher up, it moves faster because there are fewer obstructions.
 
I'm just worried about trying to guy these guys down.  That's why I am thinking about two strut bars at 45* off compass.

You have that, and you also need a braking system in event of wind speeds above about 45mph. I actually saw one of the BIG ones get destroyed in a wind storm......not a pretty sight, and you want to talk about damage???? Wonder what the insurance requirements are for something like that. Gotta give solar panels credit, all they do is sit there and collect dust.

Nothing would please me more than a blade flying off, going into my next door neighbors window and cutting his swartz off.  LOL

While it's increasingly painfully obvious that 98% of 'mercans (and
Canuks?)  have an abysmal degree of scientific literacy, and may
not understand the fundamental issues, making it incredibly
frustrating, similar issues arise with evolution, stem cells, science
funding etc, but in the current matter I'll just limit it to agree to
disagree about the absurd dissing of incentives and gov't support or
participation. As a scientist, anyone involved in virtually ANY kind of
basic scientific research knows that is complete and utter balderdash,
a idiotic statement of breathtaking magnitude, sorry, and I can give
COUNTLESS examples of technological advances  (and the concomitant
technology related JOBS) that have been discovered, developed, and even
commercialized, with gov't funding, including my own son's research in
advanced photocells at Brookhaven Labs, cutting edge development 
of Thin-film Photovoltaics here at Binghamton University's Thos. Watson
School of Engineering Center for Advanced Microelectronics , integrated
circuit research at the SUNY Albany Center for NanoTechnology, and
other examples, beyond number,  but then again it'd obviously be a
total waste of time to attempt to convince anyone completely blinded by
politcal idealogy... politics has no place in science, sorry. 



The laws of physics make photovolatic efficiencies of 60% virtually
impossible, even plants aren't nearly that good, and it's not as much
about efficiency now as of cost, so what will spread the tecnology is
getting cost way down, even at levels of current efficiency. Work is
proceeding apace on the cost aspect not 5 miles from my house, in
research in Thin Film Metal Diffusison at the Bing U Watson School and
Enicott Interconnect Technologies. I can only say know whereof before
pontification.

Steve I'd like to see the particular installation, a guy I've met runs
NRG in Hinesburg VT, one of the leaders in wind measurement technology
for the industry:  http://www.nrgsystems.com

Ed. . .  I got the answer how these smaller ones get away without overspeed protection.  I am told the blades this guy is using it made to stall at 3000 rpm.  Meaning the blades will just not bite anymore air.

The challenge is that each site is so unique that indivualized
measurements are almost mandatory to optimize the equipment and
location. That's what NRG does, they're the world leaders in that
field, a small company started by one physicist/engineer 20 yrs ago and
now a big success, CEO/COOs Dave & Jan Blittersdorf were sort of
neighbors back when we lived full time up there, they had a good sized
turbine in their back yard.  Many major wind farms and large
corporations use their instrumentaion to optimize and monitor
performance, very important for electric utilities. You could always
get a recording anemometer, prices have come way down due to
digitization, and collect data for various heights and locations before
deciding on an exact  installation location.

Some turbines have automatic blade feathering capability that is sensor activated above certain wind speeds.

The bigger units bring allot of problems the smaller ones don't have.  The ones I'm using are very low for the price per watt.  51 cents a watt.  I've seen other prices out there at 1.50 a watt for the same amount of output.

Very cool... reminds me of an old Aeromotor water pumper (I'm a old farm boy remember)...

I always wondered about taking an old windmill and driving a bunch of 12 v car alternators to charge up a battery bank.


There was interesting aticle in our local paper just this morning about
a local suburb that is adopting new ordinances for wind turbines,
mentioning that they are really growing fast in popularity: 
"Newer models of wind generators are designed for rooftops and
residential neighborhoods.  They can reach heights of nearly 30
feet and provide payback on investment in as few as 5 years, making
them attractive to homeowners, officials said."   You were
right on about that Steve! 


Some residents here are concerened about noise, safety, and want that
town to adopt a 3 acre minumum, fences, permits and engineerig drawings
for every installation!! Get yours up before it gets difficult!

That funky looking bracket on the left is the wall bracket to mount the pipe/towers with.  That;s the bottom one.  I ahve a 12.5" over hang to deal with.  The poles are 20 feet and will be about 20 feet above the ground.  If you look at the bottom bars, there is a bolt in the end.  The cross bar where the C Clamp will go will hinge.  This is how I will put the towers up.  The generators weigh about 46 pounds with the blades.  So I can assemble them, clamp the pipe to the base. and using a pully, can stand them up.  Then I can clamp the top end to a single bracket.  Above the roof, instead of using guy wire, I am going to truss them together in a triangle with rigid pipe.  So each tower will be tied to each other with a piece of pipe, and on each end a long pipe will go to the ridge on the roof to another bracket I have to make yet.  You'll see

Steve forgot to mention how much fun he had drilling a hole through 13 inches of solid oak just above the house foundation for the PVC conduit piping for the wire feed into the basement --and another two stories up into the wall.
We went through three drills,a sawzall,hammer & chisel,you name it..
plus it rained on and off all weekend and both of us got soaked.
