an unexpected benefit

If you read the last post, you'll know we've recently added a compact dehumidifier to the mix, and we just encountered a rather unthought of benefit there.  Yes, the boat is slowly drying out, but that's not it.

One of the pains in the butt in winter is:  the dock water is shut off to keep the pipes from freezing.  That means I have to drag containers of water down to the boat to refill the water tank by hand, not my fave.  For the last few weeks or so, though, the tank has been getting empty less often, and we couldn't figure out why.  I mean, we're using the same amount of water to do dishes, etc., right?

The difference has been that we'd taken to dumping the water bin of the dehumidifier into the washwater basin.  The water may have a bit of dust, but it's essentially distilled water, and fine for washing stuff.  Tallying up how much that amounted to, it's been around a gallon a day, all told, which has made a significant difference in how much water I've had to drag down an icy dock.

So, for winter at least, my plans of just piping the condensate into the sink or the bilge have been changed.  That water is too valuable to waste.

Just another little lesson learned.

Mungo and the Tropical Rainforest

or:  the Condensation follies.

I was in one of the big box hardware stores the other day, and I saw a couple wrangling over what humidifier to buy.  I found myself wanting to go grab them and say "Are you out of your minds?  That thing puts water IN the air!!!"


Okay, so we've lived on a boat for a bit.  It's kind of odd, when normal homeowners are looking to put water INTO the air, we're looking to take it out.

In winter, the air outside is bone dry.  Inside, not so much.

For those of you ignorant of the joys of living aboard (and I kid, there are many), if it's a modern vessel you are living in an impermeable shell of fiberglass.  The purpose is, of course, to keep water out, which it does admirably. One of the side-effects, though, is that it also keeps moisture in the boat.  You exhale, the moisture goes into the air.  You make dinner and reduce an inch of soup stock, that inch of moisture goes into the air.  You turn on a Propane heater, it pumps moisture into the air as well.  You use the composting toilet, some of the moisture goes into the air.  No big deal, of course.

Until it's winter and the outside air chills the hull and the deck house.  Then the moisture condenses. .

. . .in the main berth. . .

. . .right over your heads.  The long and the short of it is, it can literally rain inside.  It can do it on some of the coldest, most unpleasant days of the year, and it can make your bedding and clothes sodden even though you have refrained from using the squirt guns in the boat all year like your wife told you she'd leave you if you didn't do....

Nuff said

Over our five years aboard, we've tried a number of solutions with varying success, so I thought I would detail a few of them to help get you guys into spring without your bedding rotting or you contracting pnumonia.

First and foremost--and this is a simple one--occasionally vent the boat.  Just open everything up, even if it's cold outside.  You shouldn't leave it open long enough for surfaces to cool off (which you would then have to heat back up again) but enough to flush out the warm, wet air with dry, cooler air from outside.  Doing this periodically really helps, but obviously you can't do it too often or you'll wind up with a heating bill approaching the national debt.

Adding more insulation helps quite a bit as well, preventing  the creation of cold surfaces on which water may condense and has the side advantage of making your vessel warmer and lots more cosy.  This doesn't, however, remove any water from the air, and in a lot of vessels there just isn't the room to add a lot of new insulation.  Things like ecofoil (metalized bubblewrap) are a decent option for oddly shaped, hard to get at spaces.

Small solid fuel stoves can really help dry out the air, but their mere presence alarms a lot of Marina owners.
Solid fuel stoves--Charcoal, wood, wood pellets and the like--are great at drying out the air.  They pump a lot of damp interior air up their chimneys and draw in dryer outside air to replace it, and that works.  The times we've used a wood burner aboard the air has been pretty much bone dry.  The problem is: a lot of Marinas and insurance providers are terrified of wood burners, fearing the sparks (frankly, I think propane is far more dangerous) and won't allow them.

Small USB fans are great for drying surfaces prone to condensation.  Plus they help when it's hot too.
Next up--and this one surprised us--fans.  This last winter we tried pointing a few low wattage usb fans at the places that were condensing the worst and, lo and behold, they dried off.  For such a low cost, low power alternative, they have been amazingly effective.  Presumably the water condenses elsewhere, like in the hull, but at least it's not over the bed.

Lofting your bedding so some air can get underneath the mattress can really help keeping the bottom of your cushions from getting drenched.  It doesn't have to be much, just a few millimeters, just enough so any water under there can evaporate and escape.  The water is coming from you, and it can eventually utterly saturate your mattress.  Caveat.

Chemical dehumidifiers like DampRid do work and pull a surprising amount of water out of the air, but they're disposable, fill up quickly, and are expensive over time (and often rather messy to deal with).  Not our fave.

Small, compressor-less Peltier device dehumidifiers are a low power option for small spaces.

They don't however, remove a huge amount of moisture.  Here's the removable water tank.  Not large.

We have also used a couple of small, Peltier device dehumidifiers currently on the market.  The things are very small,  have no compressor, and consume very little juice, but they only can remove a very small amount of water from the air.  They're ideal for small, enclosed spaces like lockers, but not really terribly well suited for larger, wetter spaces.

In the past, true compressor based dehumidifiers were kind of out of the running for a lot of vessels.  They were too big and ate too much power (a 40 pint dehumidifier is almost the size of a small refrigerator and uses a lot more juice.)  Lately, though, we've seen a number of 20 pint or less units hit the market.  These gizmos are very quiet, small enough to sit on a counter, and can pull the same amount of water out of the air in a couple of hours as one of the Peltier device units can do in a month.  They do, however, consume a fair amount of electricity.

New, 20 pint and less compressor dehumidifiers can sit on a counter.
In a few months, the weather will turn, the air will warm, and condensation won't be an issue.  We'll forget all about it until the first frost of next fall, when our own little rain forest will trigger a mad scramble to dig up one of the above solutions.  Living aboard a boat, you live with nature, good and bad, and have to adapt as best you can.  It's a small price to pay to wake up on the water.  Wouldn't have it any other way.

More shortly.  Enjoy the coming spring.

And now, a brief historic interlude. . . .

Well, over the last couple of days I've been dealing with having a wisdom tooth removed (not a recreational activity I recommend, btw), so that's rather put the squelch on boat work while I get to play the sympathy card, whining piteously, and, in general, getting out of things I normally have to do.

Still and all, not worth it.  Get your teeth cleaned, kids.

At any rate, I've spent a bit of the time surfing mindlessly and came to realize just how many new viewers this blog has acquired over the last year.  Welcome, guys, and thanks for stopping by.  I also realized that, unless you've been riding with us on this trip for a bit you might not know who we are, so I thought I'd take a moment of my recovery time to tip you off.  Let's see. . . .

We're Don and Gail Elwell (and, of course, first cat Magellan).  We're long time artists and teachers, both retired college professors, and active experimenters, creators, re-enactors, larpers, and geeks in general.  Gail, my companion for (ulp) near 35 years, is a teacher, sculptor, amazing chef, and collage artist.  You can find her work on Facebook and at her blog at life, art, water. Her most recent works are some rather amazing collages, beautifully painterly works, that I highly recommend you check out.

Emergence, collage, Gail Elwell 2018
For myself, I've been a writer and theatre geek for most of my life, have started a couple of very successful theatre companies, including the Greylight theatre of Illinois and the Grindlebone Arts Collective in Baltimore, taught at a number of institutions, and in general made a public spectacle of myself.  In recent years, I've mostly been a writer and editor, publishing a number of novels and play anthologies through Wild Shore Press (created as Grindlebone's in-house publisher).

Rather proud of this one.  Available hardcopy or Ebook here.
At any rate, as part of the work with Grindlebone Arts, we set up a thing called the "Center for Bypassed Technologies" on the Grindlebone site.  It was the confluence of our working as historic re-enactors, our love of history (and science fiction, futurism, and general oddness), and my own geeky fascination with the technologies that were bypassed because of cheap energy.  This led directly to the creation of this blog, and of the original shantyboat Floating Empire. If you're interested in the rational that started this whole thing, give a click here and see how and why we started this voyage all the way back in '14.

In the intervening years, we've built ( or re-built) three vessels, Experimented with solar power systems, electric drives, paddlewheels, composting toilets, new construction materials, brewing, food preservation, wood gasification, kerosene stoves, vertical gardening, and a host of other things, all while continuing to write and do artwork and, in general, get ourselves in trouble at every opportunity.

2019 should be a really interesting year for us.  We'll (hopefully, FINALLY) get the drive working well enough to travel in our electric cruiser Tesla's Revenge, we'll be doing more brewing, lots more elaborate cooking, and I'll have two new novels (Zarabeth's World and the sequel to my novel The Ganymeade Protocol --which people have been bugging me to do-- titled The Flood Tarot) out and a poetry compilation of the real and virtual worlds called called Virtually Poetic (I'm editing that one) featuring real world poets and poets from the Second Life virtual environment.
I've got the sequel to this coming out in 2019, so you should probably pick up a copy and catch up.
We've noticed of late a huge amount of interest in things like our diy composting toilet (with diy urine diverter) and the electric paddlewheel drive.  I promise we'll be putting up more details, designs, upgrades, updates, warnings, and ideas about those in the coming weeks--I feel like we're on a roll with that--as well as all sorts of other useful and interesting things.  I just wanted to say thanks so much for all of you who have joined us in this trip.  Your comments are always appreciated, or you can reach us at Mungo@thefloatingempire.com.

Stay tuned,
More to come

Notes on DIY Urine Diverter

This thing is surprisingly simple and effective.
Having lived with our DIY Urine Diverter in our DIY Composting Toilet for near on a year now, I thought it might be a good time to address the "what worked" and "what didn't" of the thing.  For the initial posts on construction, you can go have a look here.

In general, the thing has worked really well, and with very few problems.  It extends to nearly two weeks the time between needing to empty the solid waste from the toilet, and makes that job less arduous because the mass is far lighter without being chocked full of pee.   Not having liquid pooling in the compost bucket means far less chance of insects or odor.  We use a spray bottle with a weak bleach solution and spray the diverter after every couple of uses, which keeps the smell virtually nonexistent, and the bottle (a disused 1 1/2 gallon cat litter container) is far simpler to empty than dumping the entire composting bucket, I can tell you.

There, however, a few things that we might have done differently (and which we will do differently in subsequent versions) that we thought we'd impart.

First and foremost, we used 1/2" (about 13 mm) tubing for the drain.  The interior diameter of this hose is only about 3/8"  (about 9.5mm), which is fine for drainage.  From the beginning, however, we've used mostly wood chips and wood stove pellets for mass in the composter, and dropping even a single pellet into the diverter can plug the thing (happens about twice a month)  necessitating using a piece of wire or something to dislodge it.  Not a deal breaker, certainly, but irritating.  In future iterations, we'll endeavor to use a wider diameter tube, which should solve that instantly.

Since this was a retrofit to a composting toilet we'd already built, we had to get a bit creative with routing the tube to the bottle.  Because it looks a bit like a novelty drinking straw, it's rather easy to kink it when pulling or replacing the compost bucket.  In designing a new housing, we would opt for a much more straightforward (and shorter) route for the hose.

Since the initial install, we've had to play a bit with both the height and the depth of the diverter to keep it from hitting your bum on the toilet.  This was pretty easy, and involved screwing the thing in place half an inch lower and using a pocket knife to cut the curve of the top of the diverter a bit more deeply to keep it out of the way.  Neither affected the efficacy of the unit.

By the way, rotating the compost buckets is a plus.  Even with a liner, the plastic still manages to pick up some stink (though it isn't evident until you go to dump them). Being able to leave one out to air while the other is in use keeps that down .  I'm curious if a stainless steel bucket might be more resistant to retaining odor.

When choosing your diverter bottle, virtually anything will work, but as unattractive as it may be, I'd strongly recommend getting one in which you can easily see the liquid level.  Humans produce a surprising amount of pee, and though we've only overtopped it once, it wasn't a pleasant experience cleaning it up.  There are a bunch of other fixes for this, including possibly sealing the hose into the bottle while providing an air vent of some kind, but the simplest is just to be able to see just how much of the smelly amber stuff with which you're dealing so you can empty it in a timely fashion.

Lastly, note that, if you're in a non-mobile situation, routing the urine hose permanently into a dry well or into a garden or flower bed (urine being a major source of nitrogen) can mean you NEVER have to empty the thing and your flowers or lawn can reap the benefits.

All in all, I'm really happy we built the thing and rather wish we'd done so sooner.

Hiking at Marshy Point Nature Center on a sunny December day.
The late fall has been as erratic as the rest of the year here on the Chesapeake.  Two days ago it was sunny and 60 degrees F.  Today, it's barely above freezing.  Still, we did get in a lovely hike at one of our favorite places here (Marshy Point Nature Center) and managed to finish getting our stuff into the storage space.  Now we've got a couple of chilly days, suitable for finishing the first draft of the novel at which I've been working.  Close now. 

Fortunately, the solution to chilly feet is ALWAYS a well padded ship's cat.
So it's a couple of days of writing and artwork, and then maybe we can re-address the electric drive controller.

Stay Tuned.

AAAAAANNNNNDDDDD Life gets in the way....

No, we haven't forgotten about you.  We've had to do a bit of necessary repair work on our cockpit enclosure (winter coming on) and have had to move our storage from the Marina building basement to a private storage facility further ashore (they're doing some renovations and we're kinda in the way). 

The wheel is in place, at the proper depth, and wired in.
Last week, we got the support lines replaced with chain and rerouted our wiring to connect the motor.  We booted up the sysem, turned the rheostat and, low and behold it turned.  It turned both forward and back.  We were ecstatic. . . .

. . .or were until the NEW motor controller--from the same company--went *pop* fizzzzzzz and quit. 

I checked the motor load and our wiring, and that doesn't appear to be the problem.  I just think the stats provided with these cheap Chinese controllers really don't match their capabilities.  So we're in process of getting and installing a more robust unit.  As soon as the current ice storm is over, we'll give it a go and give you a full report.

Winter finally caught up with us today:  snow and ice and rain.  We were bright enough to do our shopping yesterday so we have a day hunkered down in the boat, drinking tea, doing artwork, writing, and in general, having a quiet day of it. 

In coming days we'll be testing the new motor controller, installing an electric water pump for the galley (finally giving up on these crappy marine galley pumps....they either seem to be utter plastic junk or way more than we can afford), and doing a review on our flexoglass wheelhouse enclosure at a year of use, wind, and sun exposure, so stay tuned.

More very shortly.

Electric Motor Install: Part IV: In the Water

....and if you haven't figured it out yet, these headings don't really mean a whole lot.

Yesterday we removed the Kayak that was supporting the wheel--which took a bit of finagling--and lowered it into the water for the first time. 

Mercifully, it hits the water evenly and at the right depth
Of primary concern was the depth of the buckets at their lowest position.  Ideally, they should be about 2" below the water surface.  If we were far off that, we'd have to remove and reposition where the wheel was attached to the stern.

Happily, once we got it off of flotation and let it down, the bottom bucket was almost EXACTLY 2" below the surface. 

Occasionally, I win one.

So today we'll get chain cut and make the supports permanent (at present it's hanging from the blue lines you see above).  We'll wire up the motor and see if she works properly.  Look for a test on the water today or tomorrow if that goes well.

Wish us luck.

Electric Motor Installation Part: the third

FINALLY a fortuitous conjunction of tides, weather, help, and sunshine made it possible for us to get the wheel in place.

These chain supports will support the aft end of the wheel frame and will allow for adjustment.
Here's the stern, cleared and ready for the wheel.  The wiring is leading out the old engine exhaust tube on the Starboard side.
we dropped the wheel off the dock and onto our Intex kayak, which let us line it up with the old mounting holes that had been the outboard mount.  The thing is now firmly connected to the stern.

here's a shot from Port, showing the kayak step on the side of the wheel.  The aft lines supporting eh back of the wheel frame will be replaced with chain as soon as we're sure of the lengths.
With help from a nice slipmate, we rolled the wheel off the dock onto our Intex Kayak, which let us get is lined up with the stern far more easily than what I'd originally planned (Thanks Gail), snugged it over, and got it lag bolted in place. 

Tomorrow, of course, they're predicting rain, but when that clears, we'll pull out the kayak, set the depth for the wheel, hook up the wiring, and try the thing out.

Wish us luck.

We actually have gotten rather a lot done while waiting on weather and tides.  We made a lovely batch of Perry (think hard cider, but from pears), and did a lot of resetting of lines to make room for the wheel.

We bottled the Perry on Halloween night.  Initial tastes are promising, I can tell you.
We spent Samhain evening with friends, toasting the Pagan New Year.  Hope it's a much better one for all of us.

Happy Samhain!
Oh, by the way, we both voted:

Go do this
You should really go do that.  Really.  It's important.

Electric Motor Install 3.somethingsomethingsomething

Finally a nice day and we managed to get some work done in getting the wheel ready to mount.
Everything you see that isn't red (yet) is carbon steel and has to be painted.

We used the nice weather to do the last of the touch up painting and to get some rust preventative paint (which mercifully matches the wheel) on all the steel parts that aren't stainless, those being the driveshaft, flanges, and pillow blocks.

We also got the motor mounted.  Here it is covered with plastic while we finish painting.

Here you can see the pillow block bearing, driveshaft, and connecting sleeve all painted.

The beast is now ready to install.
So today I'll install two strong eye-bolts to the wheelhouse frame for the support chains (we'll start with line until we're sure of the length) and then, hopefully (tide and wind cooperating) we'll get this puppy on and working over the weekend.

Wish us luck.

More shortly.....one hopes.

Of composting toilets and rain

No, we haven't forgotten about you.

We're still sitting here halfway through the paddlewheel installation, but every day this week it's either been raining, thinking about raining, threatening raining, just having rained, or too windy to get anything done.  Hopefully, after today, we'll have five or six days of decent weather and can make some progress.
Magellan is REALLY bored with all this rain.

It's life on a boat.  You deal with nature.  It's part of what we love about it, but it can get in the way sometimes.

In that regard:

I've noticed of late a LOT of interest in the Composting Toilet/Urine Diverter/Toilet build info posts.  I mean, rather a lot.  Would you guys be interested if we put together a little Ebook combining all the information we've learned from the start of the original Floating Empire on composting toilets and their care and . . .um. . .feeding?  We'd probably stick in on kindle or somesuchwhat for download.

Let me know in the comments if its a go.

More shortly, I promise.
