Learn to design and make a range of low cost  technologies for self reliance .

Bob will take you through the principles/laws of nature  we will be work with, how to create design using these principles and then show you examples of all of these technologies in use here at the Koanga Institute/Kotare Village

You will also get your hands dirty making biochar and a rocket stove

This workshop will be a mix of theory design and practice

The following technologies will be covered

  • Simple legal composting toilets ( designed to recycle nutrients)
  • Simple legal, very low cost greywater system designed to recycle nutrients
  • Rocket stove cooking and heating from simple to legal in house stoves and ovens  etc
  • Solar Ovens
  • Solar Food drying
  • Biochar
  • Light earth building – We are looking for a low cost way to build using local materials. Bob and our intern Vitor have been doing lots of trials of light earth building and you will get to look at them all and discuss pros and cons. 

About Bob Corker: Bob has been involved with Permaculture design for over 30 years as a self- employed environmental consultant and farmer. During that time his work has involved many individual permaculture designs, including homesteads, small farms and larger pastoral farms. He spent 15 years as a landscape contractor specialising in constructed wetlands, including large municipal sewage treatment ponds, suburban stormwater ponds and channels, and the design and construction of used-water treatment systems for permaculture households. He was also involved in the design and development of the Kohatu Toa Eco-village in Kaiwaka, a small intentional community in Northland NZ, where Kay and Bob lived until 2007. He is a co- founder of the Koanga Institute, and has a particular interest, within the Institute, of developing light earth building techniques and appropriate technologies for autonomous housing and simple living. Bob has co-taught many Permaculture Design courses and shorter Permaculture workshops. He is presently designing and developing Kotare Village, a 50 family rural village/intentional community near Wairoa, Northern Hawkes Bay, and developing a small family farm within the Kotare Village, based on Management Intensive Grazing, Perennial Polycultures and closed loop breeding systems to create the best possible stock for Kotare Village and a regenerative soil ecology.
