Hydroponics + Fish Tanks = Aquaponics?

An interesting idea:

Your One-Stop Shop for everything Aquaponic:
[...] Aquaponics is a hybrid food growing technology combining the best of aqua-culture (growing fish) and hydroponics (growing veggies without soil), and it’s completely organic because the fish waste is your natural fertilizer and that means no pesticides. Aquaponics USA is dedicated to sharing information, developing products and bringing awareness of this life sustaining technology to every American home and School because it’s time Americans become Food Independent. [...]

I found this interesting, because for some time we have been breeding Guppies at home. One member of our household has often opined that, too bad we aren't growing something more practical, that could be used as food.

The Aquaponics system seems to be using large tanks of fish (Tilapia!) as a food source, but also using hydroponic plant bins as filter systems for the fish tanks, thus using the fishes waste products as nutrients for the plants, and using the plants (and beneficial bacteria with them) to keep the fishes environment clean and balanced.

What I'm not sure of though, is the greenhouse they are housed in. How is it to be heated in the Winter? They are in the high desert of California, where it even snows sometimes. And would the cost of heating the greenhouse, void the benefits of the food production? What I mean is, how could it be cost-effective? A quick look around the site did not reveal the answer. I will be looking around the site more, it has lots of links.

Also, I've seen seen Tilapia at the Supermarket. Damned UGLY fish. Don't know what it tastes like though. I suppose we'll have to try some soon.
