Dr Mike Page from the University of Hertfordshirt takes you on a tour of the Cube, a 3x3x3m eco-home in which one person can live with a minimum impact on the environment. Shot by Allan MacDonald at the Edinburgh International Science Festival, April 2011. Please note: I forgot to mention the combination-microwave oven, largely because I left it in Hatfield.
