Scott’s Pepsi-G Stove

If you’ve ever backpacked any distance you’ll appreciate the need to reduce weight, taken to its logical extreme by the sort of folks who cut their toothbrushes in half. This ultra-light subculture, to our benefit, seems to be populated by engineering types who like to create useful lists and detailed instructions. And, even if you don’t backpack, these innovative ideas can be used in your emergency preparedness plans.

One of my favorite ultra-light backpacking gadgets is the Pepsi can stove, which has reappeared on the interwebs, after a prolonged absence, here.

To make a Pepsi stove you take the bottom of a 12 oz Pepsi can and the bottom of a Guinness Draught can and, after a series of precise cuts and pin pricks you end up with a nifty cooking stove that uses denatured alcohol or methanol (both easily obtained at any hardware store) as fuel.

Efficiency-wise, if you consider the ratio of weight to heat output, you’re better off with a commercial backpacking stove and fuel canisters. But such stoves are expensive and the fuel canisters are only available at camping and sporting goods stores. The nice thing about the Pepsi can stove is that it’s almost free to make and you can find the fuel at any hardware store. I keep both a Pepsi can stove and a MSR backpacking stove in my backpack. That way I’ve got a backup in case one fails to work.

Mrs. Homegrown here:

I thought I’d toss in a little more detail for those of you unfamiliar with the concept. A Pepsi can stove is tiny and very light weight, good for two things–ultralight backpacking and as a simple cooking device for what some people call a bug out bag–emergency gear that is ready to grab and go.

I’ve taken one with me backpacking, as my only stove. It works fine, but it is limited in its capabilities. It can boil a cup or so of water at a time, enough to make one person a hot drink, or enough water to rehydrate a pouch of something. You certainly can’t make pancakes over one, and if you have a family to serve, you might want to consider carrying more than one of these stoves.

My camping set up included the stove, a sawed off Foster’s can (you know, those extra large beer cans) as a cooking pot, a circle of chicken wire to balance the Foster’s can upon over the stove, and a bit of foil to block wind. It all tucked inside the Foster’s can for transport and weighted hardly anything. Oh, and I kept the fuel in one of those plastic collapsible water bottles.

As Erik says, a lightweight camping stove and proper fuel canister is a much more flexible and powerful option, but little Pepsi can stoves can’t be beat for price or weight.

Here’s our 2006 post on the same subject–along with a nice photo of ours burning.

Iron Sulfate as a Concrete Stain

My concrete Platonic solids stained with iron sulfate.

I’m not a big fan of concrete in the garden. It raises soil alkalinity (a problem for us, here in the Southwestern US) and it prevents rain from infiltrating into the ground. That being said, concrete is occasionally useful and/or unavoidable.

But I also don’t like the color of bare concrete, nor can I afford the high price of concrete stains. Thankfully there’s a cheap way to stain concrete with iron sulfate, a mineral supplement you can get at nurseries in the Western US (it can be harder to find elsewhere, but Amazon caries it).

Iron Sulfate gives concrete a pleasing, rust colored stain. I recently ended up with a bunch of patio pavers that I stained with iron sulfate in a concrete mixing tray using about a quarter cup per gallon of water. You can also mop it on. Varying the strength of the iron sulfate/water solution you use will increase or decrease the intensity of the stain. Remember that there’s no going back, though. Once stained you can’t get it out.

The Construction of Secret Hiding Places

I love alternate views of our normal notions of domesticity and home economics. On a recent trip to the book section of a large surplus store I noticed our first book The Urban Homestead right alongside books on burying weapons caches, wiring solar panels, acting as your own dentist and assembling SKS rifles. We certainly have exciting company on this journey.

One book in particular caught my eye, The Construction of Secret Hiding Places by Charles Robinson. You can download a pdf of this book for free here. Of course the fact that this info exists in book and interweb form means that the secrets aren’t, well, secrets anymore. Nevertheless, I’ll never view a stairwell, baseboard or that useless space under the dishwasher in quite the same way again.

Homemade cat scratcher

I feel like I should apologize to non-cat people for all the cat-related content we’ve been generating of late. This should be the last cat post for a while. (At least until the widdle snugum wuggums does something adorable!)

We picked up this cat scratcher idea from Modern Cat. That version is much more polished than ours, in fact, it’s downright cute. Ours is also too small–we need to add to it a bit. But you can see how it’s made: strips of cardboard coiled up like a a cinnamon roll, duct tape at the breaks. If you go to the original, you’ll see how they finish the edges.

Easy. Kitty likes it.

Are Pallets Safe to Reuse?

Now you know. Pallet parts have names.

As a fan and proponent of reusing pallets in building projects, such as chicken coops and compost containers, I’m often asked if I think they are safe to use given that shippers and manufacturers fumigate them with pesticides.

In the United States quarantine regulations require that pallets be treated with methyl bromide, a pesticide being phased out due to its adverse effects on the ozone layer. According to Mary Howland Technical Service Manager at Great Lakes Chemical Corporation, a supplier of methyl bromide,

Methyl bromide products are restricted use pesticides. A certified applicator license is required to purchase and use these products and strict adherence to label directions/requirements is mandatory. Under normal fumigation conditions methyl bromide is a gas and when the pallets are properly aerated according to label instructions, virtually no methyl bromide residue remains on the pallets and wood materials.

Now I’m not a methyl bromide fan and I find it’s use as a soil fumigant in agricultural applications appalling.  But I’m not too worried about reusing pallets. That being said, a Tylenol recall was linked to the use of tribromophenol (TBP) to fumigate pallets. Though, depending on if you believe the trade organizations behind wood pallets or plastic pallets (they hate each other), the Tylenol recall may have had nothing to do with TBP which is not used to fumigate pallets in the US.

So, as with most issues on this blog, no easy answer. But I’m still not concerned about using pallets as a building material.

More Pallet Composters

Thanks readers for sending links to some attractive pallet compost bins. The one above is at http://thriftify.wordpress.com/2009/03/12/easy-to-build-pallet-compost-bin/.

Another nice one at http://www.ecodaddyo.com/node/94, though I like to keep the bottom open and the compost in contact with the ground. Correction: the bottom is open on this composter.

It ain’t made of pallets but it looks like it will work nicely and you sure can’t beat the scenery. From Devon Morgan.

Compost Bin Project From Our New Book

Natural Home and Garden magazine has excerpted a shipping pallet compost bin project from our new book Making It: Radical Home Ec for a Post-Consumer World.

I’ve been using shipping pallets as a compost bin for a few years now and they work great. A compost pile, in my humble opinion, should be a minimum of a cubic yard in order to jump start the heat and microbial life that makes for good compost. Nail together a couple of pallets and you’ve got a cubic yard sized pile. 

I’ve got two bins, side by side, but wish I had three. Mine also look like hell since I put them together in a hurry. I much prefer the bin the folks at Motuv in Kansas City created:

To answer ahead of time a question that always comes up–am I concerned about contaminated pallets? In short, no. A longer explanation will have to wait for another blog post.

Leave a comment on how you store compost. And if you’ve got an aesthetically pleasing bin I’m especially interested. Leave a link to a photo.

Mosaics

Above is a table the Kelly and I made many years ago with glass mosaic tile. We copied a portion of an ancient Roman mosaic depicting sea life. It took about 40 hours of painstaking work.

We still have a box of glass tile sitting in the garage and I’m thinking about breaking up the ugly concrete patio in the back yard and doing some mosaics. Kelly is less than enthused about this for a number of reasons, not least of which is that it will take me away from more pressing matters such as a back door that doesn’t open and a non-functioning computer network.

Nevertheless I was inspired to return to mosaic work after seeing the stunning garden designs of Portland, Oregon based pebble mosaic master Jeffrey Bale.

A pebble mosaic from Jeffrey Bale’s blog

You can view Bale’s work on his blog and read a great how-to article Bale wrote for Fine Gardening Magazine.

Our squid table was made by gluing the tiles directly to the wood and grouting once all the tiles were in place. This would not work for exterior mosaics. Instead, for my patio I would glue the tiles to a piece of paper and then set them into a mortar mix in place (the indirect method).

Using pebbles as opposed to glass mosaic tile, by the way, cuts costs way down. Should I get permission to do the back patio I’m thinking of combining pebbles with small areas of glass tile. In fact, I may just stop answering emails so that I’ll have the time to do this!

Photo Tour of the Root Simple Compound

New, as yet unnamed, kitten enjoying homebrew. Photo by Emily Ho for re-nest.

In case you’ve tired of the continuous coverage of Osama Bin Laden’s compound, how about a look at ours? Writer and photographer Emily Ho sure did a nice job putting together a photo tour of our crib over at re-nest in a post entitled “Kelly and Erik’s Urban Farm.”

Funny, when I look at our house I see all the work I have left to do, the chipped paint and broken concrete. Emily managed to capture the pretty stuff. Thanks should also go to Tara Kolla of Silver Lake Farms who helped us redesign the garden last fall.
