What the fuck are you babbling about?
Why don't you post the name of what you are talking about?
Better yet, why don't you ask your neighbor's nine year old kid
to help you get to google and enter the name of the company and
learn how to do the research yourself without asking any more
inane pointless questions?
Anyone who would have anything useful to contribute (obviously not
you) would know what I'm talking about. I purposely did not put in
the web site as I don't want to look like I'm posting one of those
fake postings to promote a web site. Are you always an ass hole?
for windmill you must have a windy unobstructed spot, preferably high
on a hill.
my best friend built one in 1960 it has a 14 foot prop, a sophiscated
control system that detects faults and shuts it down in say a
overspeed condition if the brakes fail. too high a speed can rip it
apart, as he once found out when the brakes got covered with ice:(
but it has never produced power in big useful amounts:(
solar panels require a sunny climate, the sunnier the better. their
upfront costs are so high they are rarely a good investment, unless
you live somewhere like arizonia or southern california.
a solar water heater can provide some return for heating your homes
water, to supplement you regular water heater
probably better way to spend money is super insulating your home, with
closed cell foam, new windows etc. at least the payback wll be in your
sorry to be a gloomy gus but its just the facts..
Yep. The sun lays down 745 watts of energy per sq meter. At noon. On the
Equator. On sunny days.
The only way to increase this value is to move the orbit of the earth closer
to the sun.
After adjusting for latitude, conversion efficiency, clouds, etc., you might
get, at best, 200 watts per sq meter of collector. Plus, accounting for the
energy costs to build the equipment, transportation, and installation, the
pay-back period is almost forever.
From everything I've seen and read by the time you buy a bunch of "seconds"
solar cells and put them all together in a panel you may as well just buy a
panel. Recently I've seen panels advertised for just over $2/watt and there
is speculation that they may go even lower in about a year. Keep in mind
that this "breakthrough" has be on the verge for a long, long time and
hasn't happened yet ;-) There's a recent thread about it on alt energy.
homepower (PV Panels $1.98/Watt? vaughn 9/20/09).
As for windmills, as was mentioned you need a spot with really good,
consistant wind, a high tower, and probably so many permits that it would
never result in a positive gain financially.
I see these as viable options to produce electricity if you live somewhere
where the grid is not available. Otherwise it is almost always cheaper to
buy it from the electric company.

Not yet... but I am keen to throw an alternator together sometime though,
with some blades to drive it. The barn roof's about 40' high, so
with a tower atop that it might stand a chance of doing something slightly
useful (I'm very skeptical about wind power, but it'd be a fun experiment
Machining blades that are both strong, balanced, and with the right
profiles is sure going to be interesting!
Regarding solar, do you mean panels producing electricity, or ones for
heating water? The latter should be pretty easy to do, inexpensive, and be
capable of doing useful things (even if nothing like 24x7). From what I've
read on homebrew PV panels though, it sounds like it's just not worth the

Yeah, I suspect you couldn't get enough height to make it really useful

Uh huh. Waiting a few years for costs to come down and then buying a
commercial panel might be the best bet (I'm sure they'll get cheaper;
right now I'm not convinced they save enough over their lifetime to
justify the cost)
I keep getting told that domestic heating's the real expense though, so
anything simple you can do to minimise that is worthwhile (insulation,
lots of south-facing windows etc.)
