When I was at CSU a few days ago, data from these small windmills
and a larger freestanding windmill were being displayed on a panel in
the
EE lab. The big windmill was generating 1/2 the power of the small
ones, with the same swept area, because the wind was only 3-4 mph
and not really enough.

Got a water tower?


Go fast. Take chances.

Hmmmmm, my latest SketchUp dreams are tower-like, and I've been poking
around a little for windmills to run up top. The idea of small
multiples makes sense but poses an aesthetic problem.

I'm tempted to build my own even though I'm a terard when it comes to
electricals.

Wind makes much more sense to me than solar.
When do you really, really want electricity for survival? Not when the
sun is shining. No, you want it in crappy weather which is not sunny
and is often windy.
Imagine a power grid with Seasonal Affective Disorder.

Back to the topic of unintended consequences... I just stumbled upon
this quote yesterday while reading "What Do *You* Care What Other
People Think?" (yes, the quotes are part of the title):
"The real question of government versus private enterprise is argued
on too philosophical and abstract a basis. Theoretically, planning may
be good. But nobody has ever figured out the cause of government
stupidity - and until they do (and find the cure), all ideal plans
will fall into quicksand." -Richard P. Feynman

Good luck with that. Sounds fun - you can get a small unit for ~$600,
though to power a full-time house, you'll need about 100 times the
power.

Depends where you are - the northeast is fairly shitty for both.

That's why they invented batteries.

Better pic the alumni association sent a link to:
\http://www.csuohio.edu/engineering/wind/
The data page doesn't seem to be working, when it did it showed
the power from the test setup versus a standard (big, single)
fan.

Go fast. Take chances.

Supplemental is just fine. Lay there on a windy night with all the
lights off,listening to the meter spinnign abckwards until the fridge
kicks on.

Yep. But I've got wind aplenty here. We are one of three towns in the
state that has to build for 100MPH winds, and I'm maybe 900 feet from
open water.

Man, those batteries have been the sticking point for years. I mean I
guess a big ol'stack o' lead/acid batteries are fine for home power. I
was thinking electric cars and such when I thought the hurdle still
lies ahead.

Um... yeah. like I said ... terarded in that way...
but I will study that. There's no excuse except I haven't tried hard
enough to understand that shizzle (so I might sizzle). I need a good
book on that stuff...

no excuse...
but enough negative self-talk!

Now, do you mean you designed that squiggly in and out diagramatical
schematic whatchamacallit?
