Rocketing into Fall

Thursday, October 21st, 2010

It’s hard to believe that the building season is already coming to an end.  The house isn’t as far as I’d hoped, but I’ve begun to get used to that.  As long as the progress is tangible it’s hard to get too depressed.  Watching the granite footing go up with Emily’s hard work has been exciting and has turned the house into a work of art.  The loft and interior wall studs in conjuction with the first half of the base layer of earthen floor have added a new dimension to the interior and although it’s still probably a whole building season from being done the finish line is in sight.

With the first light frost of the year and the leaves changing and finding their way to the forest floor where they’ll keep the tree roots well-mulched and cozy I’m reminded of my own winter preparations.  It would be easy to get stressed about all of the work still to be done over the next couple months, but I know I’ll get it done. Just knowing that I won’t have to spend the winter cramped in my tin can of a camper again is enough to keep my spirits high.

My most pressing project is getting the rocket stove done.  A rocket stove is a type of wood-burning stove similar to a masonry stove in that rather than the heat going straight up and out of a normal chimney, the flue runs horizontally through a bench made up of really heavy materials like rocks, bricks, and clay so that the heat is absorbed inside the house before the stove gases exit.  This means that the temperature of the air leaving through the flue is only a hundred degrees or so, even though the stove burns cleanly and efficiently at over a thousand degrees.  After setting up a mock-up of the heat riser guts of the stove at the last work party there are at least 3 new stoves in the planning stages by impressed observers.  I foresee many winter nights and days spent on the thermal mass bench in the future.

The earthen floor base layer is only a little over half done.  I held off doing the whole base layer because I wanted to bury the rocket stove in the floor so that the floor will also hold the heat.  I was more than ready to be done with the tedious work of mixing and leveling the floor.  Each batch of mix only created a couple square feet of floor space, so it would easily take 300 batches to do the whole layer.  Even after 3 weeks of running a couple of fans to dry it out it’s just now really begun to dry out.  There are two more layers, which involve a lot less material, and thus less mixing and work.  Any more work on the floor is going to have to wait until next year so I’ll have a half-gravel floor for the winter.  No big deal.

The solar power system has gotten a significant upgrade.  We’ve now got 400 watts of panel on the roof and new MPPT charge controller which is significantly more efficient at charging the batteries with those panels.  I’ve cut a couple trees down that were blocking significant sunshine and I’ll have to cut down several more before it’s all said and done unfortunately.  I also need to get some more battery capacity since we’re making way more power than we can hold when it’s sunny, but it only lasts a couple days with regular usage.

My first attempt at a brewing beer since I stopped about 5 years ago was a resounding success.  I’ve been doing a lot of reading on brewing beer with more raw materials so I can lower the price and have more control over it.  I’ve also got my first batch of wine brewing and plan on doing a lot more brewing and experimenting this winter as my pet project.  I’d like to have a lot of beverages tucked away for next year.  We go through a lot of beer and wine, and I figure this will cut down a lot on our recycling and expenses.

Emily finished the solar dehydrator that she’d taken on as her own pet project.  We’ve tried bananas, apples, persimmons, tomatoes, acorns, and herbs and they’ve all been delicious.  I’m especially fond of the fruits when they’re only partially dry and chewy.  It’s going to be a lot less depressing not seeing tomatoes and other veggies going bad because we don’t eat them or give them away fast enough.

Dakota headed out in September, and Emily has just headed back early to Ohio.  She’d expected to stay through Thanksgiving, but her father’s health has taken a turn for the worse and she’s gone back to spend some time with him.  Both her and Dakota were really crucial in getting as far as we did this year, not to mention just being good company.  Hopefully I won’t be too lonely this winter though, Justin is putting the finishing touches on his tipi cover and is planning on having a tipi-raising party in the next week or two.

A Gravity All Its Own

Sunday, July 11th, 2010

There have been a lot of great developments at Maya Creek in the 6 weeks since my last blog post.  I’ll start with the oldest and work my way up to the present.

The roof has been completely insulated.  Dakota and I spent 2 days blowing insulation into the roof space we’d created between the rafters with used billboard tarps.  The inside of the roof isn’t the prettiest, but I’m planning on getting some kind of fabric or saris, and hanging them up over the tarp to make it prettier and to add some character.  Even without doors or windows it’s noticeably cooler and less humid inside the house.

After the roof was finished we started preparing the walls for the earthen plaster.  That mainly involved stuffing cracks and spaces with straw slip, essentially straw dipped in a clay/water mix about the consistency of cream. We also taped off some parts that we wanted to protect from the plaster.  Afterwards we made a gritty adhesion coat out of flour paste, sand, and clay.  The adhesion coat was smeared on all of the non-straw surfaces that were going to get plastered such as wood, parts of the gravel bag stem wall, and the metal compression wires.  We also stuffed some of the spaces between the gravel bags with cob to minimize the amount of plaster that would have go in there to even it out.

Next we rented an air compressor and stucco gun and blasted the straw bale walls with clay slip, the clay/water mixture about the consistency of heavy cream.  At that point I bought a cement mixer and generator to help with the mixing and it has already been incredibly helpful in mixing the plaster as well.  While I could see mixing plaster by hand for a small project, the cement mixer has probably doubled the speed at which we’re plastering both with the time it takes to actually mix and the energy saved and used on applying the plaster.

The 4th of July: Get Plastered weekend event was a resounding success as far as I was concerned.  14 people showed up at one point or another and there were a dozen that helped with the actual plastering.  It was extremely gratifying for me to see my old friends getting along so well with my new friends.  It took us a good 6 hours to get 3 of the outside walls done and we finished up the last wall in a couple hours on the 2nd day.  Dakota and I built a dock at the lake just in the time for the party and the bonfire was quite impressive, seen here with flames only half as high as they got to be.

It sounds cliche, but it really is hard for me to put into words how grateful I am to everyone who has helped me along the way so far, not just the people at the plaster party, but all the support I have gotten with the ecovillage project.  It is fueling the progress here, not to mention giving fire to my determination to see this through.  Without it, this simply would not be possible and so I thank you all from the bottom of my heart. I have an optimism about the future that I have never experienced before as an adult.

Whew, now that I’ve let that wave of emotion sweep over me let me get back to the business at hand.  I have a new work exchanger, Emily.  She arrived from Ohio a day or so before the plaster party.  She’s inquisitive and hard-working and we seem to get along well.  Dakota was planning on leaving after the plaster party, but seems to find it harder and harder to leave.  This place seems to be developing a type of gravity all its own because he’s not the only one.

Over the plaster party weekend I talked with Justin and Melainia and they wanted to start construction on a DIY yurt.  I’ve already seen some of the initial plans on it and it seems fantastic.  They’re wanting to start some time this summer and I couldn’t be more thrilled.  They’re already good friends to me and I welcome them whole-heartedly as the first community members apart from myself.  The construction of a small dwelling in the actual ecovillage area fits in exactly with that I’d envisioned for the first phase of the main ecovillage area construction.

I’d only met Patrick once before early this spring.  I liked him after that one encounter, but after the plaster party weekend he’s already entered the ranks as a good friend as well.  He’s been building a geodesic dome about an hour or so from here and hung around an extra day after the plaster party weekend.  He seemed to be at home here and I was sad to see him leave.  I’d already been conspiring on how I could get him more involved here when he e-mailed me and said that he had to be a part of Maya Creek sooner rather than later and wants to build a small dome here this summer.

There’s this sense that the pieces are starting to fall into place and that my “start building it and they will come and help you” strategy is working.  I feel like I’ve been able to attract exactly the kind of people I’d been hoping to find.  The ecovillage seems to be well on it’s way to becoming an actual village and not just a wild man in the woods.

So, getting back to the more hum-drum ecovillage news.  The plaster is still going up.  Dakota, Emily, and I have already significantly improved our plastering methods and are moving much quicker than I had thought possible judging by how much we got done at the plaster party.  It’s quite a relief since it was beginning to look like a herculean feet to finish the next 2 coats, especially since the next coat involves 3-4 times more plaster than the discovery coat we’re still applying does.

I’d like to put out an open invitation for a plaster party this Saturday, July 17 as well as one on Saturday, July 31.  Everyone is welcome to camp for the weekend.  There are a number of tents already set up on raised platforms with protective tarps.  A few of them have mattresses, and I’m looking for a couple of double mattresses to throw in two of them.  If you’re coming out remember to bring clothes that you don’t care about since clay can stain clothing.

In non-housing related news the garden has exploded in productivity and lushness.  Many of the companion planted flowers are blooming, tomatoes are ripening, zucchini, squash, and cucumbers are growing faster than I can pick them, and my only regret is that I can’t spend more time there examining bugs, growth patterns, and generally just poking around.  A couple raccoons got in one night and ravaged the sweet corn, but it’s recovered fairly well and I’ve since trapped and relocated the rascals about 20 miles away.

A couple fruit trees have died, and some are struggling.  A few seem to be doing really well though, which is I suppose to be expected in essentially unimproved clay soil.  Next year I’m really going to kick my compost-making operation into high gear and make it so that I can grow pretty much any plant the climate will allow.  I have the sources for material and means of delivery, just not the time to do it right now.

Sadly I’ve lost two of the three laying hens I bought this year.  The first one happened when the chickens accidentally got locked out of their coop one night and nested in a tree.  I could hear it screaming as something attacked it and ran down and scared away whatever was attacking it, but it was mortally wounded and I had to put it out if it’s misery.  The other was mortally wounded by some dogs and was likewise mercy killed.  It’s really pretty depressing, and I’ve begun to wonder if the act of butchering these animals is worth the meat.  I’m almost to the point of burying them in the garden and using them as fertilizer.  It seems right since that’s essentially what I want done with my own body, except in the forest, not the garden.  Jason is raising some guineas for the both of us, and so I should have 4 or so of them running around tick-hunting in a couple months.

Maya Creek is also now solar-powered.  The wind generator doesn’t reliably produce very much power.  The turbine needs to be higher above the trees, but I’m hoping that in the winter when the leaves are down and the winds are generally stronger and more sustained I’ll see more production out of it.  If not I have a plan to raise it another 5-10′ and possibly trim some tree tops.

The 90W of amorphous silicon solar panels are doing the trick on these hot sunny summer days.  The battery bank had been consistently topped off, but as more people have arrived and the weather has gotten cloudier, they may not be enough for what we’ve been demanding.  I’ve got 2 new LED lighbulbs that put off a nice omni-directional warm light that only use 5 watts each.  Over the winter I’m also going to be looking at getting a new super-efficient laptop.

In more recent news, I’ve lost my dumpster diving cherry.  I spent most of the time laughing at the incredible amount of perfectly good food thrown out.  I didn’t even notice a smell in most of the dumpsters and within the course of an hour or two the car was packed to the brim with a huge array of food and goodies, including a perfectly fine step ladder, which had been on my list of things to get for plastering.  If I had to estimate what it would have cost to buy the stuff we got, I’d put it somewhere in the area of $200-300, if not more.

We did all of that on the way back from St. Louis where we went to an event remembering the 1877 general strike in St. Louis.  The main reason we went was to see David Rovics.  I designed David’s site about 5 years ago and had never met him until yesterday.  He introduced me to some extremely interesting people in the St. Louis area and I’m really looking forward to getting to know them better.

Maya Creek Christmas 2009

Friday, December 25th, 2009

After some soul-searching and continued annoyance with referrals to the morning after pill I’ve decided to change the name of the Ecovillage.  I’ve gone through a few different ideas and some conferring with Justin and Melainia I’ve settled on Maya Creek Ecovillage. Almost the entire watershed is on the property and it’s easily one of the most beautiful features of the land.  The road that will eventually go out to the ecovillage center will pass along several especially beautiful parts.  What a way to be greeted home!

Straw bale house with new truckIt’s snowing out here on the land today.  Big fat flakes dancing around in the gusty wind.   There was a little snow on the ground when I arrived but it melted quickly the first day.  I’ve only been out here for about 5 days.

It’s gotten colder since then, but I’m keeping warm. The propane heater is keeping the camper warm and I’ve also started using one of the kerosene lamps in the evenings, which also puts off a good amount of heat.  It makes it smell a little, but nothing like the kerosene heater did.

It’s not a large area to heat, but the camper has exactly no insulation.  That’s why I’m using a bunch of the rejected straw bales I have left over from the house to just wall in the camper for the winter.  I’m going to hang one of the billboard tarps from the trees over the camper to keep the bales dry It’s ok if they degrade a little because I’m going to use some of the wet ruined bales to mulch the garden this year.

I started on it, but didn’t want to hang the tarp first because it was supposed to snow and I wouldn’t have been here to knock it off and make sure it didn’t just collapse and tear the tarp.  Even with just third of it I’ve done it’s made a difference.  I put that part up to block the prevailing winds, but I’m sure once I get the bottom done all the way around it’ll make the floor a lot warmer too.

Camper partially surrounded with balesI wouldn’t have been here because I was supposed to be in Minnesota at the family Christmas, but the same storm that’s snowing on me made a barricade of ice between here and there.  Snow is one thing.  Ice is another beast altogether.  I’m still going up there, but just going to miss today and post-Christmas eve.  I’d been looking forward to seeing everybody and I’m glad I still will.

I’ve been thinking a lot about my goals for the winter out here.  The first thing is to get the trailer baled and get the water running, especially the hot water.  I’ve been worried that the water might freeze in the tank or in the lines, but I think once it’s all baled in that won’t be a problem.

The next thing I’m going to do is make a hot bed, which is basically a cold frame that you put compost under to keep warm.  I’m going to try growing some greens and who knows what else in it.  It’s a stepping stone to a larger greenhouse I’d like to build out in the garden area.  I’ve already got some good ideas on the design.

My next bigger and much more expensive project is to start generating some power.  I didn’t really want to spend the money just yet, but I found an awesome deal on some amorphous silicon thin-film panels. They were only 98 cents/watt, which is outrageous considering the next cheapest I’d ever found before was $1.74/watt and that was at this same web site.  I ordered 10 Kaneka 60W panels from Sun Electronics in case anyone else is looking for cheap panels.   The next cheapest place I found was Affordable Solar, but even it’s best deal is $2.69/watt and most of them are much much more.

Consider it stickeredThe camper has a battery-powered lighting system and I have an small inverter I can use for now, but 600W will be way more than enough for just me.  Even just taking the minimum average hours of full strength sunlight per year and minimum panel efficiency I should get at least 1.5 kWh/day or roughly enough juice to use my 90W power hungry giant laptop for almost 17 hours/day.  Obviously I wouldn’t use my computer that much, but it gives you an idea.

There are a still a lot more expensive components to buy and then I’ll have to assemble them, the toughest of which will be mounting the panels on adjustable mounts that I’m going to make myself.  The batteries and the charge controller will be the most expensive pieces, and the inverter isn’t cheap either.

I’ve learned to scale down my expectations somewhat on how quickly I can get things done, but not as much as I had worried I’d have to.  So, building the green house and the solar power system are my main things to get done, but somewhere in there I’m also going to set up a small biodiesel production system to process waste vegetable oil for use in the truck and future vehicles and engines.  That’ll cost a bit to set up as well, but nowhere near the expense of the off-grid power system.

Pink is not a snow fanAnd, as if I could get all of that done I’m also thinking about building a nicer larger guinea/chicken coop with insulation that I can fit inside the greenhouse.  It’ll keep the birds warmer and they also produce some CO2 and body heat for the plants.  At some point I’d like to be able to move the coop to another greenhouse though so I’m going to keep that in mind.

Other than that, the straw bale house is standing up nicely to the elements, even without plaster or gutters.  The tarps certainly aren’t very charming though.  Everything else said and done, I’m enjoying living in the camper.  It’s cozy, everything is within arm’s reach, and it takes 5 minutes to clean from top to bottom.  I hope everyone else out there is staying warm and dry.
