Home-scale double-barrel top-lit-up-draft biochar retort stove!

Biochar Retort

“Biochar can be made cleanly and effectively on a home-scale, using a biochar retort.”

Biochar is a desirable material for anyone looking to improve their soil. Buried, it acts as a water retainer, nutrient trapper, and home for beneficial bacteria and plant roots, and it continues to support life and fertility for thousands of years! On a home-scale, biochar can be made from waste wood or mulch, using a biochar retort.

Benefits:

  • Produces biochar – a permanent soil amendment
  • Burns clean and hot
  • Can be used for heating or cooking
  • Can be fuelled with waste materials
Design for My Biogas Digester

Biogas Digester

“Biogas is the perfect solution to modern sustainable cooking.”

Biogas is a mixture of gasses that are produced as anaerobic bacteria break down organic matter. It is flammable, capable of producing a clean flame for cooking and heating, and it can be derived from as simple a feedstock as your kitchen rinse water.

A biogas digester is a container holding water and bacteria, which can be ‘fed’ organic matter to be broken down, and which collects the resultant biogas, to be tapped off either to a collector for storage, or directly for burning.

Benefits:

  • Creates flammable gas
  • Creates fertiliser
  • Runs on kitchen rinse water
  • Safe and Clean

Rebar Fence Trellis 02

Rebar Fence Trellis

“Make a self-supporting post-less fence trellis out of rebar!”

In Spring 2011 I wanted to make a fence across the backyard for three reasons; to enclose a chicken run, to grow fruit vines, and to support a future pvc arbour I had planned. Traditional fencing options were expensive, but I found a way to do it using only rebar steel mesh. The result exceeded my hopes.

Benefits:

  • Creates Vertical Space
  • Encloses Chickens
  • Supports Vines
  • Lasts 10 Years
