We created the video below for a local-food summit which we were invited to co-host. It includes many pictures and information about our (Becky and Bill Wilson) reasons for starting Midwest Permaculture and how we designed and evolved our own home. The blog-post that follows is a condensed version of this hour-long video presentation.
Hello All. Our natural building workshop this weekend was a great success.
Hassan Hall, our natural-builder friend from Dancing Rabbit Ecovillage, taught a great hands-on class this past weekend here at Midwest Permaculture.

Everything was ready to start the next phase of construction on the first of 9-small earth shelters we have planned for EarthCamp Village. It was now time to put the rough coat (or base coat) of earthen ‘plaster’ on to the walls of clay-slip-straw that had been packed in last fall. Continue reading “Natural Building Workshop Successful”
This is an April 2016 Blog Post on how we built a Thermal Mass Rocket Stove at Jordan Rubin’s ‘Heal the Planet Farm‘.
(We cover the foundations of rocket stove building at every Permaculture Design Certificate (PDC) course we host.)Schedule of Upcoming Courses
We call it the Epic Greenhouse Rocket-Mass Heater because of it’s sheer size and multiple modifications we designed into it. The whole stove is built around an 8″ flue system that exits outside of the greenhouse below floor level, under the greenhouse end-wall, and then turns towards the sky.

The key modifications we made to this stove that are not usually found on more traditional rocket mass heaters are:
The feed chamber is very large capable of holding full-sized firewood logs so it can be loaded to burn for up to 4 hours at a time and produce a lot of heat.
The thermal battery or thermal mass is below grade and insulated so the heat will not wick into the soil surrounding it but instead radiate up to keep fish (aquaponics system) and bedding plants warm even in the dead of winter.
We installed a multiple-speed flue fan and a flue damper near the end of the exhaust pipe to give ourselves greater control over the speed of the exhaust and even the burn. We can slow the exhaust down to hold the heat in the thermal mass longer when it’s hot or speed it up when we need a stronger pull to get it started. We know this is unorthodox and a bit like cheating, but it’s very helpful and the fan is variable speed using very little electricity.
At the last minute this winter we decided to tap our mature maple tree (just one tap) and boil off some sap to make a small amount of maple syrup. I was equally interested in building an experimental rocket stove as an evaporator with the materials I had on hand. It worked great!
With some landscaping bricks, a dutch oven and a bit of home-made cob we had our stove chugging along in about an hour… maple syrup in 5 hours. 3+ gallons of sap made 1 cup. of syrup. Here are some pictures:
I built the stove by dry stacking (no mortar) the bricks to form a chimney and burn chamber. We nestled the dutch oven in to serve as the top of the burn chamber so it would receive direct flames for a hot, rapid boil.
Here is a brief picture summary of our 2015 Winter PDC at Midwest Permaculture in Stelle, IL. As expected, during a winter course with high temperatures below 32 degrees, we did not spend a lot of time outdoors but we did manage to capture a few pictures of these activities.
We have been invited by a family in Southern Missouri to assist with the design of a 320-acre farm. They want to transition the land into a permaculture landscape capable of producing a wide range of perennial foods (nuts, vegetables, herbs, fruit, etc.) as well as livestock (beef and goats).
Over generations, rain has slowly degraded this sloping landscape with a loss of nutrients and topsoil. It is not uncommon for a million gallons of water to wash off this landscape with a 1-inch rain. Continue reading “Bulldozer Digging Swales”
