As an agricultural engineer that has been involved in development all my working life I was fascinated by some of what I saw. For me the water powered funicular rail car was the highlight. Our guide was knowledgeable and was able to answer most of the questions posed by the group we joined relation to solar water heating, PV electricity, wind powered electricity generation, water powered electricity generation, thermal insulation etc. It whetted the appetite to learn more. My wife was very interested in the poly tunnels and the wide variety of food crops being produced. There were all kinds of learning activities for kids. The WISE training centre on site offers a variety of courses, both academic and practical, at different levels aimed at sustainability. If this kind of thing interests you make the effort to visit.
