Wind power effects... for Wolfgang

Nice to see you back Wolgang. Hope you are well.

I recall you have an interest in wind power. I though you might be
interested in the following link that describes one off-target effect on
bats.

Thanks Tim, doing as well as can be expected, I guess, for one in robust
good health and possessed of sufficient resources to pursue a few at a time
of a host of varied interests......time being the limiting reagent. I hope
you can say the same, or better.

This is very interesting. A few months ago I spent the better part of a day
talking to a DNR naturalist at the Horicon Marsh state wildlife refuge in
southeastern Wisconsin, who expressed a concern about the effects of a
proposed wind farm on the local bat population. Evidently there is a
substantial population that roosts through the winter in a nearby cave. As
he didn't say anything specific about what the machines might do to bats, I
assumed he was simply concerned about collisions. I was skeptical about
bats being unable to avoid the vanes under any conditions. The wind farm,
which covers a large area to the east and northeast of the marsh, is now
fully operational and I have not yet heard anything about the expected
casualties among birds and bats. However, I am aware, largely due to
monitoring a birding oriented listserve, of studies (both planned and
currently underway) using volunteers to make routine checks under the
turbines. The problem detailed in the story linked to above sounds highly
plausible and I'll be watching the studies I mentioned closely to see what
the results are.

Thanks for the heads up.

bat and bird impact statements are usually required as part of the
regulatory approval process for wind farms. i'll be interested in your
report and opinion of the experience up there. the wind farm i saw in
wyoming this summer was visually appealing on the windy plains and hills
in unitas county. while i have no doubt there are and will be bat
casualties, i doubt it will be of sufficient significance in most of the
areas wind farms will be located.

On a much smaller scale, the Dutch have done some tremendous work in
area of urban wind power. They have a helix type that mounts on
buildings and homes, generates 1.8 to 7.9 KW (depending on model) that
is quieter than a home air conditioner. I don't know anything about
the sonic levels driving bats nuts, but because of the shape, it
appears solid to birds and bats, reducing the chance of bird strike.
There are even areas in South America where they are mounting these on
cell phone towers to power the systems.

I attended a conference a couple of years ago on windfarms. One thing
I remember is that cats kill 80 times more birds than windmills,
buildings with windows somewhere around 40 times.
Killing raptors was a problem as they sometimes fly backward relative
to the ground.and "back" in the blades.

Lots of durability items to overcome but it looks like fun.
If'n we had a bit of wind here this would be a candidate for my next
failed energy project.

That's pretty neat, though I'm not sure how practical it is. Kinda noisy
too, it seemed. However, it might be just the thing I need for my planned
huntin' cabin on my uncle's mountain property.

As far as videos go I like this one just a bit better. It's short and to the
point.

Mark,
Projects like this to me are mostly for fun (and to prevent brain rot)
but a lot can be learned from them and this fellow demonstrated how to
get the into wind power on a shoestring. Of course most of us don't
have CNC capabilities in our basements and perhaps a pulley & belt
driving the alternator from the 87 Olds out back might suit the
tinkerer better.

If you decide to do any solar or wind projects for your cabin this
site is the best home energy site I've ever found and if you have any
interest at all in such stuff it can keep you occupied for many, many
hours.

When I experimented with a solar panel some years ago the fellow who
runs it was very helpful.

Thanks Kiyu,

I bookmarked the site and will go thru it when I have more time--classes
began again on Tuesday last :~^ ) and :~^ (

I fished more this Summer than I have in previous 3 Summers, and sure will
miss the free time now that classes have begun, but I'm getting very close
to completing my program. Can't wait to finish, so that I can start a new
program, likely in Geology/Planning.
