I was wondering if I could receive any input on an idea I had for a Permaculture Outdoor Kitchen Design? I have had many ideas for sometime now and could really use some help ironing down a simple first design. I would really love and appreciate any advice, input, or links for help on a few specific issues, so that I can make this a reality. The basic idea is to build an outdoor kitchen based on many permaculture ideas, such as:
1. Living Roof: The roof of the kitchen would hopefully be a garden or living roof, growing edibles (How do I build the correct living roof with wood, 20ftx14ft, structurally sound, to support the weight of the living roof w/ edibles growing in what medium?
2. Water Harvest: Excess water runoff from the roof will be harvested to be used throughout the kitchen(What could be a simple and affordable filter for the water specifically from the living roof to make it potable?)
3. Biogas: Food scraps and organic waste could hopefully feed a small biogas unit to produce a gas stove top to cook the food or boil water, as well as create fertilizer (Has anyone had experience with the Homebiogas unit?, does it really work?)

4. Grey water: Grey water irrigating the gardens surrounding the kitchen
5. Refrigeration- Hoping to implement a chest fridge adaptation to run off of a small solar set up (From my understanding I have read the adapted chest fridge has operated on 100watts per day, so I am hoping a small 100 watt PV system could potentially power it. Has anyone had experience with the adapted chest fridge's power usage?)

In a nutshell, that is the basic idea. Grow it, eat it, and feed it, over and over again. I am also trying to keep this as small scale and affordable as possible. I have tried to explain permaculture many times to many people and I am hoping that when they have an opportunity to walk around and play within it, it will explain far past any of my best words.
Thank you so much for any advice, input, or thoughts
