Of course we did, the thing is that the activity that that electricity and piping sustains within makes its construction cost-effective. I'm not diminishing farming in any way, I was just skeptical that such an investment would work necessarily because farming isn't as profitable as other businesses that could occupy the same space.

It's been cost effective for quite some time. Check out the site, they've already done the math, the systems have been tested extensively. Combine that high level technology with the natural concepts and organization from www.growingpower.org and it only gets better.
Well there you go, it can work.
I agree, they need not be mutually exclusive, simply supplemental to each other. That said, it still occurs to me that there's a reason that it's not done on a greater scale, as in why we don't see very many omega farms. I figure it's because there is no serious food shortage in the industrialized world. If there were, increased prices would make such farms, in addition to the traditional models, very profitable. On the converse, building them and increasing supply would lower prices. While good for the consumer it makes farming in general less profitable.

Supply and demand. That's my theory as to why we don't see more omega farms.
