Our guest this week is journalist Kris De Decker, the creator of Low Tech Magazine, a blog published in English, Dutch and Spanish that covers low tech solutions in great depth and detail. Without exaggeration, I think it’s safe to say it’s my favorite blog. On the podcast we discuss high tech problems, Catalan vaulting, fruit walls, Chinese wheelbarrows, open modular hardware, fireless cookers and alternate forms of the internet.

Low-Tech Magazine

Yesterday, Erik and I had the privilege of interviewing Kris De Decker, the creator of one of our very favorite Internet resources, Low-Tech Magazine. Those of you who know Low-Tech will understand our vast excitement. To make it all even happier, he seems like a really good guy.

If you haven’t heard of this blog, believe me, Root Simple readers, if you like what we do here, you’ll love Low-Tech. This is the sort of site you fall into and stay for days.

Our interview with him will appear on our podcast next Wednesday, but in the meantime I suggest you whet your appetite by reading some of our favorite articles:

How to Make a Simple Paint Can Rocket Stove

Update: Root Simple reader Ruben questions whether it is possible to build a true rocket stove out of metal. Ruben sent me to a Facebook post by Benjamin Rosen who says, speaking of another metal rocket stove, “Actually, you can say that this is not a rocket stove. A rocket stove gives great heat from a small amount of fuel because it burns very efficiently at high temperatures. This is achieved by having a ceramic lining in the combustion chamber that permits very high temperatures because it insulates the combustion chamber, and because it absorbs and returns the heat to the chamber by glowing white hot. A metal lining, as we see in this design, will shed heat to the environment and therefore cannot reach the high temperatures needed for a true rocket stove. Metal, in any case, would melt at the temperatures achieved in a true rocket stove combustion chamber.

Rocket stoves cook food with small pieces of wood efficiently and with much less smoke than conventional wood burning stoves. They also help prevent deforestation since you can burn small twigs trimmed off a tree rather than burning logs. Search the interwebs and you’ll find may different designs. But they are all based on burning wood in an “L” shaped tube to create a chimney effect. Insulating the tube increases efficiency.

A friend who lives in a remote part of Southeast Asia is visiting us this month and we wanted to come up with a design for a rocket stove that could be made from commonly available materials with nothing more than hand tools. Our goal was done rather than perfect. Here’s how we did it:

DIY Portable Pizza Oven

I just spoke with Eric Rochow of GardenFork.TV .(He’ll be our guest on the next podcast.) If you don’t know Gardenfork, you should. Eric has put together a lot of cool videos and podcasts. One of my favorite is this portable pizza oven. I’m thinking of building one for local events. For more info on Eric’s pizza oven check out his pizza oven page.

Root Simple Busted: Drying Racks, Clothes Lines and Cheese Puffs

Folding-Clothes-Drying-Rack-YW-03-

For many years I’ve wanted to have one of our writer friends do a John Stossel style exposé on us. We’d have them drop in unexpectedly and witness some of the environmental transgressions that take place at the Root Simple compound such as hidden cheese puff stashes and the weekly, patrician moment when my fencing uniform goes through the, gasp, dryer.

Joanne Poyourow, founder of Environmental Changemakers and a guest on Episode 033 of our podcast, called me out (in a very nice way) on the dryer issue yesterday when I admitted to using it. She noted how much energy dryers use and how she ditched hers many years ago and has never looked back. We have a gas dryer which means that, while we use less energy than an electric dryer, we’re still complicit in the use of fossil fuels. In short, fracking is supporting my attempts to parry, riposte and flèche.

The truth is that we had a clothes line for several years when we first moved into our house. But like many clothes lines, it was low quality and eventually broke. I never replaced it. Joanne mentioned going through several flimsy clothes drying racks before settling on a higher quality drying rack that can be used both outside and inside.

My question of the week for you, our dear readers, is what kind of drying rack do you like best? Do you use a line? Do you prefer one to the other? Do you have a favorite, non-flimsy rack or clothes line?
