Underground greenhouse

Whilst this particular example by the Benson Institute is situated in a Northern Hemisphere cold climate region, the same principle should apply in Australian conditions. Obviously the aim would be to provide relief from the heat rather than cold by tapping into the thermal mass of soil.

In it’s simplest form it is a rectangular hole in the ground 1.5 – 2 meters deep and covered by plastic or ideally plexi-glass greenhouse sheeting. A rammed earth wall (or dry-stone if you want to get fancy) at the back of the construction and a lower wall at the front provide the angle for the clear. The roof seals the underground greenhouse providing an insulating airspace and allowing the sun to warm the space providing a stable environment for plant growth.

Here is a follow-up video from the original author showing a subsequent year

Open Tech Forever

Open Tech Forever – Indiegogo Video from OpenTech Forever on Vimeo.

This is a great example of the use of “Open Source” concepts related to agriculture, resiliency and self-sufficiency. OTF is dedicated to developing new and improved, open source versions of modern and cutting-edge technologies. In the open source spirit, they are creating free, online, high quality educational resources demonstrating how to understand, redesign, and replicate our products.

It covers not only the skills, designs and the train of thought behind the development process but also the facilities, tools, and materials that it takes to really make a variety of technologies but also to develop and document open hardware, manufacture products for sale, and host public workshops to provide a hands-on learning experience for improved skill development and retention.
