KB - I actually looked at Aquaponics first but ruled it out due to the high number of root vegetables I wanted to grow. I also wanted to try and stick to sustainable ways as much as possible. Essentially if the lights went out tomorrow could I still do it and because of the reliance of Aquaponics and Hydroponics on pumps that just didn't seem like the right choice..
It's not so much the energy usage but the complex components required. For example if the pump failed and I couldn't actually go and buy a replacement would there be a natural way to replace this. It's a bit survivalist but having recently read a fair bit about peek oil I have to wonder what kind of goods might be available in future.
However I really am compelled by the faster growth rates in Hydro and Aqua. I bought Bill Murray's DVDs - interesting stuff.
On that note have you heard of anyone successfully growing root veg using Aquaponics?
I'm looking at different ideas for more sustainable aquaponics systems, not using pumps. I was going to try to set up a tank this spring but have been too busy with other projects and repairs to do so. My idea is to have dense edible and useful aquatic plants on one side of a tank and fish on the other, and circulate the water with a small wind-powered fountain.
Ludi from my limited knowledge I believe that would be similar to a 'floating raft' system.

This system that I toured had 3 to 5 pumps (though it should have only had 2: primary + backup), water heaters to maintain 85 degrees, and four 200-watt grow lights for supplemental winter lighting. Their monthly cost through summer was $20, and winter was about $50, with fall and spring falling somewhere in between. I think that could be more like $10-30 with a better pump set-up and slightly better insulation than what they were using.
I guess I'm not able to see how those costs were figured if they are using PV and batteries. Sorry, just confused....
Anyway, sorry for being sort of off-topic here....
Ok, thanks for clarifying, I guess I got confused by your mention of a sustainable and reliable power supply...
