I just did a report card inDecember. Why another already? In December we hadn’t really done
winter. Now we have. And here in Minnesota, we never ever forget
winter. If we do, we die, recipient of a
Darwin award.
Also, we’re thrilled with the
growing interest in Home the Land Built:
an article in the Star Tribune, visits by others on the journey,
upcoming presentations at Midwest Mountaineering and REI, the conversation
Linda is having right now with Jen, a freelance French TV journalist. Not only
do we feel compelled to spread the good news about what is possible, but like the Shirtless
Dancer at the concert, it feels good to know we’re not
just lone nuts. And these fellow dancers
deserve to know what it feels like prancing around with our shirts off. So here it is.
I believe that a report card is the
beginning, not the end, of a conversation.
Since I released the last Report Card in December, this conversation
concerns what we’ve learned about Cold Season performance. To obtain the
grades, Linda and I engaged in a (sometimes challenging) reflection. Except
for Humanure, our perceptions differed by no more than a third of a grade, e.g.
A- / B+. Being the tough teacher that I am, I’ve
reported the lower of our two grades, so A- / B+ is reported as B+, excepting
Humanure. Alright, let’s get it over
with: on with the lowest grades.
But the lowest grade is only a B-? I guess the first overall comment should be “this
is amazing performance”. Still, don’t
we deserve a talking-to with ourselves?
Hot
Water = B-.
OK. I’ve beat the poor backup Bosch
tankless to death. No change here. Fortunately, we barely use the backup now
that the solar hot water has kicked into spring gear.
Water
= B.
We were very impressed (and relieved) to finally discover we had 1800
gallons remaining in the cistern after 4 months without harvesting a single rain drop. Yet the water situation is not as welcoming
for guests as we’d like. I must confess
that my nephew once drank out of the forbidden tap rather than the Big Berkey
filtered crock. Why wouldn’t he, or anyone, drink from the tap? A bigger challenge is communicating the
scarcity of our winter water supply to guests so that they know not to
over-consume. We Minnesotans---with
little awareness that water is actually not infinite---pretty much just let it
gush. Linda suggested we get a meter so
guests can “see” how much water remains and better understand their
impact. It all comes back to the Right to Look.
Humanure
= A / B+. This
is the only system Linda and I disagree on.
She just wouldn’t accept how right I am.
Two issues. Linda expected less
odor from the toilet and is concerned about how it handles large groups. And she’s right. No doubt there can be, and probably should
be, some odor. Part of the challenge is guests don’t always
cover well. Covering well requires one skill: you must actually look at
what you’ve produced. Hmmm. And large groups do require changing the
bucket more often, approximately 1 bucket an hour for every 100 people. Our difference in opinion comes down to how
much these things bother us. What better
learning institute than a committed relationship?
Mindful that B grades reflect smiley
face performance, now we can move on and pretty much brag about the two Cool
Season A systems.
Electricity
= A-.
What a rally in performance. ALL due to a glitch in the software that
tells us how much juice remains in the battery. Since toggling one algorithmically-critical
parameter, we haven’t been close to the “plug-in-the-generator-now” level of
50% capacity. In fact, we haven’t sunk
below 80%. But since the change took
place during the “sunny” half of winter, we won’t know until next December if
the system deserves an A. Still, we
never dreamed off-grid electric could perform so well here in Minnesota. It begs the question why all new homes don’t
at least consider it?
Heating
= A.
Actually I gave it an A+. We
both agreed that the house always felt toasty, often a t-shirt 72F,
while cruising up to a swimwear 80F on the coldest of sunny days. I awarded
an A+ for the added wow factor. Every
night we LOVE sitting before the fire---sipping our favorite beverage---like
camping in our own house. It’s hard to
argue with cozy, clean-burning, and virtually free heat.
Done with the individual systems, I feel compelled to confess how much
Home the Land Built has influenced our grading.
For example, I asked Linda what grade she’d have given our old
Minneapolis toilet. At first she said
C+. One of them leaked a lot and they
both plugged occasionally. Yuck! Then she said, “that’s the grade I would have
given when I lived there but only because I couldn’t see the rest of the
system.” Since discovering that our
flushed Humanure eventually made its way---even depositing
pharmaceuticals---into the Mississippi, she would now give our old Minneapolis
Humanure system an F. The
point is, in Minneapolis, we didn’t even know there was a system. All we saw was a toilet. All we heard was a flush. Knowing what we know now, or what we think we know, every Minneapolis
system would probably get an F.
Home the Land Built’s Right to Look
principle enables a more true grade.
Like it or not, we see it all.
And how can anyone possibly produce a report card on anything unless they
know---with their own eyes, ears, and even nose---whether they like it, ALL of
it, or not? So, I guess I’d like the
final comment on the report card to read, “I’m proud of you. You hide very little. Whatever grade you've earned, at least you can be truly graded.”
