The Permaculture Portal

Permaculture is a form of whole systems design based on the sustainability of natural systems, seeking to reproduce that sustainability in our living environment. Permaculture designs differ based on climatic factors, bioregion, organizational goals, personal preferences and other factors. It can hence be said that permaculture is, at its core, a set of thinking tools, in particular towards awareness of context, threats and opportunities.

Though it was developed out of sustainable agriculture, permaculture design is hypothetically applicable to any field of human endeavor. The very term "permaculture" itself was first used to mean "permanent agriculture," it is now applicable to all realms of design and is now considered to mean "permanent culture".

The finished greenhouse!
Construction of an Affordable Greenhouse. The capstone project for Queen’s University 4th Year Mechanical Engineering Class,"Engineering for Sustainable Development", is to design and construct an Appropriate Technology with a quantifiable engineering result. This project is to construct a greenhouse, review the heat requirement on the system for the whole year; then, based on the materials and conditions selected, review costs associated with this and build a scaled model.

This project is the first step to easy community greenhouse development - the goal of the affordable greenhouse is to:

  1. Improve greenhose design and awareness for residential application.
  2. Demonstrate the feasibility (i.e costs) of a greenhouse in the winter months and determine the best time to install such a system for optimal crop yield.

Due to the materials selected and the cold Canadian Spring, it is not effective to construct until late April. But with better material selection and innovative greenhouse designs, it is hoped that constructing miniature greenhouses will become common practice.

Home biogas system (Philippine BioDigesters)

"It can be built as a : Do-It-Yourself (DIY) project where expert masonry skills are not required" and "by using common and inexpensive materials available anywhere."

Albert Einstein
Out of clutter, find simplicity. From discord, find harmony. In the middle of difficulty lies opportunity.
