Dream Farm

"The ideal Dream Farm 2 operates as a farm, and also serves as a demonstration, education and research centre, and incubator for new ideas, designs and technologies. The aim is to promote and support similar farms springing up all over Britain and the rest of the world not only through publicity of Dream Farm 2 itself, but also by collating and analysing data from all similar farms, by acting as resource centre and centre for information exchange".

Long article, but very interesting. The Farm at EARTH University in Costa Rica tries to do something like that, but on a much smaller scale, and without the integration (at least that's what I saw 6 years ago). But I'd really like to see a rigorous economic analysis.
