There are a few redwoods leaning against the deck and part of the

accumulate some moss but conveniently, that side is not in contact

I have a cot, sleeping bag, and some survival supplies in the office.
However, they're not for the occasional all night writing exercises,
data recovery exercises, or last minute taxes. They're for when the
roads are closed due to flood, mud, or crud and I can't drive home.
Just before I bought this house, I lived with some friends in a
crowded apartment building located about 20 ft from a major freeway.
The traffic noise was so bad that everyone had mattresses blocking the
freeway facing windows. Actually, I didn't live there as all of my
stuff was in a cramped storage locker.
How was the slab in the summer? I would expect the slab floor to be
cooler, especially if there were cold water pipes inside. An
acquaintance built a thermal sink near his house consisting of an
underground water tank containing about 500 gallons of water. The
water is not for drinking (but can be used for fire suppression).
Instead, it is pumped through copper and plastic pipes in the walls
and floor. During the summer, it keeps the house at ground
temperature. During the winter, the water is heated by his wood
burner. It is then slowly pumped through the walls and floor to heat
the house at night. It's not intended to heat or cool the house, but
rather to moderate the temperature swings so that minimal heating and
cooling will work more effectively.
I've seen wood laminate over foam board insulation (underlayment) used
on slab foundations. However, I have no personal experience:
Delta-FL moisture barrier, EPS foam, 3/8" OSB (oriented strand board),
3/32" underlayment foam, and laminate sandwich. The end result is
allegedly better insulated than a 2" elevated sub-floor on the slab.
The catch is that the slab should be perfect as wet spots (leaks and
cracks) and lumps will wreck anything you put on the slab. The
underside of a laminated wood floor is quite sensitive to moisture so
the moisture barrier also has to be perfect.

We bought our property about 25 years ago. We're about 10 miles out of
town, up on a mountain, and was surrounded by thick forest everywhere. The
county road ends a half mile past our place. We really felt like we were
getting away from it all to enjoy nature, our privacy, and peace and quiet.
Over the years the developers moved in, and immediately logged off most of
Now we are surrounded by private gated estates with 4000-5000 sq/ft mini-
mansions. Despite having 5 acres to build on, they built one right across
the road that sits up on a hill overlooking our property. It's less than
150 feet from our house. Yay... So much for privacy. To make matters worse,
their landscapers show up every Friday with multiple mowers and leaf
We used to have beat up pickup trucks and the occasional weekend partiers
driving up and down our road. Now it's mostly BMW's and Mercedes.
I miss the remote feel we used to have. We have tried to keep as much of
the forest on our own property as possible, but with less than two acres
there's only so much we can do.
Such is "progress"...
I've been dragged to plays in Manhattan and that was enough. Oh, then
there was the iApx432 launch (three days). That was *way* more than
enough. SF was much better (parking was the same - nonexistent). The
hookers a couple of blocks from the hotel were funny, far better than
those in Manhattan (even the trannies).
You might want to string some copper wire across the roof. They also
make copper and zinc strips for the purpose.
I don't like any growth in contact with the house. Any wind and
there's more work to do. It's good to keep the exterior dry, too.
Sounds like a regular occurrence. Ugh.
Like the Winter, it worked fine for a month or two into the season.
Late in the season it got to be the wrong temperature and would work
against the heat pump. Most people have this mistaken idea that only
a few feet down the ground is a constant temperature - not true. Just
notice the position of the mixing valve when you take a shower, during
Summer and Winter.
Yes, a foam board probably would have made all the difference. Much
of the downstairs of our house was tile or bamboo flooring, with the
master BR carpeted, directly on the slab. All of the floors were
noticeably warmer/colder than the upstairs floor.
I'm leery about putting anything over concrete (whether floor or
wall), for exactly the reasons you state. Concrete is porous and
moisture *will* come through. I really don't want to stop it on the
inside. My current basement has an unfinished basement and I'm not
sure what to do on the floor. I'm only planning on using it for a
shop and storage but I want to sheetrock the walls, at least, if not
put in a ceiling (though may not for tax reasons). Most of it is
carpeted now, which I'm tearing up (sawdust in carpeting is a PITA).
The problem is that the floor is dusting. Not sure how to handle it.
I remember a story about a Canadian Mounty knowing his man, responsible
for murder robbery, mayhem, etc, was one of two inside a saloon. But did
not know which man. He went in, severely kicked a dog lying near the bar,
as the dog yelped loudly and one of the two came to the dog's aid with
"poor puppy, etc" the Mounty arrested that man, and had the correct man.
Plus, Lizzie Borden gave her money to an animal shelter,

There's got to be stories.
SF was much better (parking was the same - nonexistent). The
NYC is all concrete and steel and steam. Central Park is much praised
but still awfully civilized.
SF has a small downtown, like a bit of New York, which is what most
visitors see. But it has views, trails, stairways, beaches, cliffs,
tunnels, mountains (well one, almost) if you get a couple of miles
from downtown. We passed Proposition M some years back, which
established height limits that keeps downdown from spreading. I park
on the street at home, no problem.
You've got to be a people-person to enjoy New York. You have to
actually own two or three tuxedos. Hang out in art museums.
We get the Sunday New York Times. It doesn't have comics, but it does
have Style and The Arts, which are even funnier.

One of my experiments was to rapidly electroplate some copper onto a
cathode, producing copper dust. I sprinkled it onto the moss and
added some mildly acidic water. The most was mostly gone by the next
day. I hosed off the residue, and in about a month later, the moss
was back. Grrr. Diluted sodium hypochlorite bleach (Clorox) and a
little TSP replacement degreaser in a garden sprayer works well enough
for me, or just use the overpriced commercial stuff:

Not really. Once a year at most for road closures. Maybe 4 times per
year when my car won't run, or I'm stuck with doing the computer work
after midnight. I don't use the cot much because there's no room in
my cluttered office. I just roll an inflatable mattress into the isle
and use a sleeping bag.
There's only one road in and out of the San Lorenzo Valley. Drop a
tree across it and everything comes to a screeching halt. Actually,
the tree isn't the problem, it's the safety regulations. It used to
be that when a tree falls across the power lines, PG&E, Ma Bell,
Comcast, Davey Tree, Public Works, and the local fire department all
arrive at once and work together. Lots of congestion, but the tree
was usually cleared in a very short time. The problem is that it's
not really very safe to have everyone working at the same time. So,
it was decreed that parallel processing was out, and serial processing
was better. Everyone stands around directing traffic until PG&E
declares the power to be turned off and safe. Then, the tree and
debris are removed by Davey Tree. Then the various utilities replace
the lines. Public works clears the road and declares the road
passable. Finally, the fire department opens the road to traffic.
Using parallel processing, a tree fall could be cleared in about an
hour or two. With the new improved method, I've timed the process at
between 6 to 8 hours.
Part of my foundation is concrete and rebar filled speedblock, which
is certainly porous. I used:
and some long forgotten brand of vapor barrier on the outside.
Something similar should work for a slab:

Well, that's the standard practice. If your water table is too high,
something else will need to be done. I have zero experience with such
slabs and can't offer any suggestions.
Dunno. Maybe just an overlay to seal it better? Again, I have zero
experience with slabs:

No copper color that I see. And I can show you roofs here where it's
obvious zinc works, just like whatever it is in that video. You can see
it with zinc flashing on pipes coming out of roofs. For about 4 ft below
there is no moss/algae. But I agree it's far from an ideal solution, you'd
have to put strips every 4 ft.
Up here, generally, if it is hot enough to need AC it is too humid for
a "swamp cooler". Most of the time just reducing the humidity a bit
makes it bearable - but when it's hot AND humid, we run the AC.
In some really important ways, you are missing big items. Most of the
cold coils heat transport is from condensation energy, there is no
equivalent heat of evaporation on the hot side so it all goes into
temperature rise (sensible heat). Unless of course it is built very like
conventional AC and the heat is exhausted outside.
Not sure what you mean by "you are missing big items". I think you just
agreed with me 100%. The cold coil does not cool the air as much as the
hot coil warms the air. All of the heat of condensation ends up warming
the air in the room. I guess I didn't explain it clearly.
Try this: Dehumidifier contains an electric
motor which gives off heat when it runs.
The cooling and condensing are equal, so they
can be ignored. Check the wattage used, and
that's the added (electric) heat.
That is incorrect. The hot and cold coils provide the same amount of
cooling or heating other than the inefficiencies, but the cooling does
not all go into making the air cool. The water condensing puts heat
into the coil without changing temperature. This heat at the warm coil
*does* fully go to heating the air.
Look up heat of condensation or evaporation. Same with
freezing/melting. Heat flows, but temperature does not change.

Except of course that it all balances out again when the air mixes.
The drier warmend air that comes out of the dehumidifier quickly mixes
with the rest of the air, which still has higher humidity. That slightly
warmer and drier air
then transfers it's energy to the rest of volume of air in the room/house,
heating the air and water in it, until equilibrium is attained again.
And back to the original claim, that a dehumidifier is like running the
AC and heat at the same time, it's not. That's because when you do that,
you're pumping heat out of the house, then running heat, ie electric, gas,
whatever, to replace the energy you just pumped needlessly outside.
A dehumdifier avoids that.
It had its moments but mostly boring. They had silicon there but the
big question of the day was "Huh?". That question was never answered.
...even decades later. Intel is a one-trick pony. Always has been.
Civilized? Is that why it's so dangerous?
You do know that there are a *lot* of single-family homes in NYC, too?
