I am sure there are. I was quite into aquaponics for a while as well.

I just wish these things were more common place. All these technological advances...it should be easy option for people to live in communities where they can do few hours of work a day and live simply. Yet this is somehow a complete luxury!

Instead we need cars, roads, computers, phones, to work 8-10 hours a day just to provide ourselves with shelter food and clothing.
