While researching the origins of the green movement in the 1960s/1970s, I've become particularly fascinated by John Todd and company's New Alchemist group.  They designed buildings as ecosystems.  For example: a greenhouse of food crops that was heated by a large fish tank that absorbed heat during the day and radiated it when the sun went down.  The tank had lettuce growing top of it and the water, fertilized  by the fish, would circulate throughout the greenhouse plants, both irrigating and fertilizing them.  Decayed plant matter would, in turn, feed the fish.  

I'm curious what use others have since made with this model (which was developed in the 60s, 70s and early 80s).  Any contemporary examples you know of?  I'd love to find some group that's developing open technology initiatives around it and read their schematics.

Any contemporary examples you know of?

It sounds similar to earthships.

Hello.
Earthships can hold a plant/animal/aquaculture based ecosystem, sure, I think it would be a compliment and nod to interreliance/cooperation.  For ex. some take advantage of the sun to feed their plants/indoor crops and utiltize grey water as nutrients to feed their garden. However these functions are not a requirement.  You could do that in many types of homes.  A differentiation between Earthships and many other designs is they look to utitlize the geothermal heat storage under floor to normalize temperature fluctuations which are natural; thereby lowering production and consumption of fossil emissions and deforestation, mining consequences, chemical non-biological effects, health issues blabla etc.  It is a construction concept that seeks to embrace our place and position with the earth in which we live and affects how we relate to eachother for example I don't have to be a slave to a company in order to earn my "freedom" to support a virtual economy which does not directly improve my quality of life.

Anyhow, I like where you're going with the "my home is an ecosystem with complex relationships" idea; that's the core of green my friend

Youtube has a mixed bag of close to not so close examples under keywords:
"Pond Aquaponics"
"Aquaponic Gardening"
"Indoor Aquaponic Gardening"

I also suspect you could use freshwater hair algae as air/water filtration for your home.  The algae lives in water (your normalizing mass) attached to substrates.  As nutrients touch the algae, it is used as energy by the algae which in return supplies pure oxygen and consumes nitrates, phosphates, ammonia and some chemicals depending on strain.  It therefore has potential to cleanse water naturally (potential gray water filtration), as well as being a fertilizer once removed and naturally broken down by bacteria, insects etc. Plankton will do that too, plus supply food chains with the needed primary food source.  So all these neat natural intricacies just need creative bright minds to understand how they relate to eachother and us as well as how to logistically implement.

portablefarms.com has a lot of info and developed systems.   I've been interested in it as well.
