An interesting Australian show (thanks Dirk). In New Zealand a few years ago I was given a tour around a highly automated farm, operated by just one guy, and sometimes his son...The bulls had monitors attached to their testicles to ascertain which ones were fertile and which could be used for some other purpose, i.e. slaughtered. The monitors talked to gps systems that told the farmer, Stuart, where they were. There was a rain-producing machine that could be dialed remotely to rain in all kinds of different ways.
Stuart violently objected to the proposed wind farms on his horizon.
