Nancy Jack Todd eloquently relates the history of her and husband John Todd's New Alchemy Institute (NAI) for ecological design starting in 1969 to the present day incarnation of Ocean Arks International. This book has many photographs and drawings showing systems, buildings both at their research facilities and installations around the world and many of the dedicated people who have worked with the Todd's over the years.
The original focus of their research was to develop sustainable organic food production, bioremediation, off-grid energy production, and efficient building construction methods for a virtual stand-alone closed-loop system capable of self-sufficiency without any toxic side-effects, especially, effluent. Through trial and error and much research they met their goals and became internationally recognized for the high state of efficiency their various systems achieved. NAI became a successful format and influence for many colleges to replicate on campuses all over the U.S. and abroad.
Eventually, they turned their focus almost exclusively to natural effluent and pollution remediation techniques developing the "eco-machine" system that utilizes plants, micro-organisms and fish to convert sewage to re-usable water and fish for food production.
The Todd's contributions to solving many of the world's toughest environmental problems and influence on ecological study cannot be understated, especially in the area of bioremediation. If every municipality, farm, and industrial site in the world were join the ranks of those who have already installed "eco-machine" type water purification systems to clean-up their toxic run-off, a huge chunk of global pollution could be eliminated.
This book is a must have for all those interested bioremediation and that should be everyone- a clean environment requires it.
