Any scales used in commerce MUST be certified by your
State Department of
Something (varies from state to state, as some states
have a department of
commercial sales, units and measures, agriculture,
etc, and each such
department has jurisdiction over your scale
certification). Best way to
find out is to go to any grocery store deli counter
and ask the clerk to
read you the label. There is always the name of the
department, the name of
the department head (if elected) and a phone number to
call and report
complaints or praises.
If you sell ANY amount you must have a certified
scale.

I've been looking at such systems for a long time.
Keep in mind solar only
works when the sun is out, and you still have the
problem of converting
steam energy to mechanical energy to electrical
energy, unless you just
want to heat your house. No matter how you use it,
steam requires a lot of
attention or a lot of expensive gadgets to regulate
it.
I couldn't see that steam was an better than pv solar.

That is a good idea, never heard of that one. Might be
worth experminting
with. The bad thing is when the sun is not strong in
the winter. I found
these little steam engines on the net, I did not save
the site though. I
will have to do another search. They were small the
size of a briggs and
straton or so. It would be nice to find a way to heat
the greenhouses
cheaply.

Hi everyone,
I just wanted to remind anyone that may have been
interested in trying to obtain some local native
mussels to check with their state Department of
Natural Resources. I just found out that Indiana
has prohibited the removal of all native mussel
species
and their shells from public waters since 1991
(my shell collecting son is disappointed).
The mussel hunt is canceled for the weekend but the
canoe trip isn't
.lol. The game sure has a lot of
rules
anymore. I'm still looking into the zebras and regs
governing mussels from private waters.
later,
Mark

I've been selling my tomatoes to a health food store.
I pick the
tomatoes, wash the dust off, dry with a paper towel,
and place them in two
black (nested in one another to support the weight)
growers trays. I buy
trays without drainage holes so the fruit isn't
damaged. The fruit is cut
from the vine leaving a green stem. The bright red
shiny fruit with green
stems sitting in a shiny black tray is beautiful. So
I walk into the
store with my tray filled with two layers of tomatoes.
I place the tray
into the produce scale(the one with the label "May not
be used for trade"),
say it weighs 16 1/4 pounds. I say to the produce
manager the tare
weight is 1/2 pound let say 15 pounds. Invariably she
says OK. She feels
she's 3/4 of a pound ahead (of course she's also
buying green stems the
cost of which will be passed on to the consumer). I'm
$30 richer and four
hours later she's sold out of my tomatoes. So Steve
I'm writing you this
so you can see I placed the burden of scales upon the
retailer. To me the
need for special scales is moot.

My father and I did. Amazing how arrogantly we
squandered
the heat with no energy bill to pay for the heat gain.
The problem is transferring, control and storage.
Acquisition is EASY point and cook. Rate of mirror
travel is
accomplished with gear motor running at a constant
rate.
Reset the declination every few days to stay on the
sun. If
you really want to get wild but a cheapo telescope
control
gozmo and let you imagination run wild.
Transfer must be accomplished by pumping unless you
have
SIGNIFICANT elevation difference cetween the collector
and
the consumer.
Control is easy or hard depeding on one's own talents
and/or
the talents one can contract for. Popular Mechanics
has (I'm
sure) reprints available for it's heat collector.
Write them
and ask. Probably a few bucks per article. Bet they
even do
the librarian work.
Storage takes room/space/area/cubic size AND something
in
that space to hang on to the heat and release it when
it's
needed.
The overall thingie that looms frightening is the
possibility of freezing. For Jamaicans it is remote.
For
Minnesotans - yah sure you betcha gotta worry 'bout
dat.
Using antifreeze works but anti-freeze is poinsonous.
Oil
works but heat capacity is not as good as water.
Draining
the water out of the system can work but a compressed
air
blow out must be accomplished or bad things have a
high
probability of happening.
Plenty of time before winter for mirror acquisition
and
parabolic frame construction.

There may be enough UN used parabolic dishes out
there, the type used in the
past decade for first generation satellite reception.
a little math and you
might get enough mirrors positioned to focus some
serious heat to generate
steam.
One note about steam generation, this is high
pressure stuff and not for
the back yard mechanic.This stuff will parboil your
flesh faster than you
can fire off an email. Water is generally condensed
and recovered, but water
quality (odd how I always get around to this subject)
degrades rapidly in a
closed loop system. Having been around power
generation for pulp mills, food
plants, dairies and the like, it requires almost full
time attention.
Another note, when you design a dish and tracking
system, account for
maximum wind load. Even a small residential dish can
experience several
hundred pounds of axial loading and that can result in
a new sky light or
worse, a new hood ornament on your neighbors RV.
Rmember water boils at 210
F but steam can reach incredible high temps. Imagine a
couple of hundred
degree spraying as your dish just launched towards the
neighbors house?
Everyone knows how lively an umbrella can be in a
breeze, now multiply that
by 1000. Always design for 125% and use safety
factors. You might think
about one that can fold and nose into the wind in the
event of an X factor
for wind. Nature does this pretty well too.
I'd rather hear about a nasty fish bite in here
instead of someone
forgetting to carry a decimal one more place.

I love this Idea but then agin I just love steam. The
problem is that the steam emgines on the rail road
were only 4 to 6 percent fuel efficient and the the
little one you'r looking at even less. So you could
probably bucket water faster than you could chop
would. Not to put the idea down I still love it. just
