Living in a Truck for Two Years. Part 1

2The motivation for a lot of these projects comes from having spent six years doing nothing but paying off debt.  I had a good job as a programmer in Little Rock, was living in an apartment and was making slow but steady progress towards paying it off.  The problem was that at the rate I was going it would take about 10 years and I did not want to spend that long.  I always liked the outdoors and camping, when I was living in Kenya I was in a canvas tent for a year and then a mud and stone building for the next five years or so.  In my mind a "house" was a place to sleep and store stuff.

Immediately prior to paying off this debt I had decided to hike the Appalachian Trail.  This is basically a footpath 2100 miles long from Georgia to Maine.  It took about 6 months to hike the entire distance back in 2004.  I loved it... all I had in terms of "stuff" was what would fit in a backpack, and yet I did not feel that I was lacking anything essential.

I came to the conclusion that life could be much simpler than it currently seems to be.   All we really require is food, shelter, and water to sustain ourselves.  These can be easily obtained with almost no effort in America.  Having accomplished these basic requirement we should be able to spend the rest of our lives doing whatever we want -- reading, travel, art, working on project we enjoy.  We complicate it by turning and artificial "standard of living" into a requirement.  This then drives us to turn something as simple as shelter into an elaborate shrine to consumerism that we spend the rest of our lives working to maintain.  Some people, when they reach the end of their lives and are looking back on the enormous volume of possessions that they once consumed and passed on to their heirs will be satisfied ... I am not one of these people.  When I see the stress, and fear and hopelessness that pervades much of our society I wonder if slavery ever really ended.

So sometime around 2006 I found myself with a 98 ford explorer, a pile of stuff, an apartment, a bunch of debt and an ideology at odds with my lifestyle.  I started looking at my truck.  I discovered  I could fold the seats down to make an area in the back of the explorer that was three inches longer than I was.  This left a fairly large area in which to store stuff... certainly more than I had in my backpack on the AT.  I did not spend much time in the apartment anyway.  Usually spent the evenings reading in a coffee shop or visiting friends.  Once I got over the idealogical hump and started considering living out of my truck as a possibility  the advantages (paying off my debt twice as fast) seemed to clearly outweigh the disadvantages (the comfort of having an apartment full of stuff).

I started looking for other people who had come to the same conclusion and found this:

TEN CONSECUTIVE YEARS LIVING IN CARS: Living, Traveling, Camping, Attending College, and Performing Surveillance in Cars--and Loving It!Then did some research and ordered this book.  I found out it was not a very popular choice, but it had been done.  My friends pretty much thought it was a terrible idea but eventually stopped trying to talk me out of it.

I had a few months left on my lease, so I started to get rid of stuff and make plans.  In the end I learned quite a bit, had a few surprises and saved at least $12,000 over two years.

To be continued: here

Earth Bag Hot Tub

So far everything I have listed has been done by somebody and documented somewhere on the internet.  This is an exception not because it is particularly complicated, and I imagine it has been done... but so far I have not seen any accounts on how it worked out.  Therefore, if anyone knows of anything similar please leave a link in the comments.

The end goal is to have a workable hot-tub that requires almost no maintenance or chemicals.  As a friend pointed out: hot tubs are not usually thought of as minimalistic, however I believe that this will use less water overall than a standard shower... and will be more fun besides.  I want to use earth bags to build most of the structure, all the stuff in brown in the diagram is to be made from earth bags.  This will then be covered with a water barrier, cement, and a waterproof paint.

The idea is to make a kind of simulated creek.  The sand filter at the top will consist of several levels of terraces each containing vermiculite, sand, charcoal, and gravel.  I will probably plant something like bamboo or river-cane or sorghum in the terraces for both privacy and to remove nitrogen from the water.  The vermiculite will maintain some moisture for the plants, the sand will filter sediment, the charcoal will remove chemicals and bacteria and the gravel will help drainage.  The water will flow into the hot-tub from here, will be heated by the rocket stove, and will then overflow into the storage tank where it will be pumped back to the terracing at the top of the hill.

During the summer it will not need to be heated, but when it is there will be a valve between the sand filter and the hot tub that can be shut off.  This will cause the water level to rise until it flows through the bypass leaving the hot-tub and the stove isolated so that I am not trying to heat the entire system.  It is not shown in the diagram, but the chimney from the rocket stove can be run through the bench of the hot tub so that it heats the water more efficiently.

Another possibility would be to use compost to heat the water.  Apparently a compost heap can reach internal temperatures of over 160 degrees F.  This would basically be a pile of green wood-chips soaked in water for a few days and then shoveled into a cube made out of hay-bales until it makes a pile about 6ft tall.  You run pipes through the compost and then pump water through the pipes to collect heat.  From what I understand, this will continue to produce heat for several months at a time and you are left with a bunch of useful compost.

When not in use the water would be continuously cycling through the system providing constant filtration.
