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.

Always design a thing by considering it in its next larger context – a chair in a room, a room in a house, a house in an environment, an environment in a city plan.

Sharing knowledge to build rich, sustainable lives.
Appropedia is the site for collaborative solutions in sustainability, poverty reduction and international development through the use of sound principles and appropriate technology and the sharing of wisdom and project information. It is a wiki, a type of website which allows anyone to add, remove, or edit content. Registration is encouraged but not required for contributors.

Appropedia has been described as an "appropriate technology wiki," but it is much broader than that - it is a green wiki, and a wiki for all matters of international development and aid. But most importantly, Appropedia is an open site for stakeholders to come together to find, create and improve scalable and adaptable solutions. For more about our motivation, see Appropedia:Mission.

To create a new project page, first browse the project articles and subcategories below for examples and check for possible collaboration opportunities, such as articles similar to what you're considering writing. If you are looking for ideas for your own project, check out our suggested projects. It is highly encouraged to tag your projects with their status -- you can do this with a few templates. Be Bold!
