We hope you were able to catch Sundance Channel’s premier of Big Ideas for a Small Planet last week, where they looked at eco-innovation in biofuels. don’t worry if you missed it you can tune in tonight (Tues 24 April 2007) for the second instalment, which focuses on how we build our homes. See Michelle Kaufman’s Glidehouse, a stylish, prefabricated, modular house that reduced construction waste while still using green materials like bamboo. Catch up with architect, Carlton Brown, who has shown that residential eco-architecture can be affordable and healthy. Then there’s the MIT engineers, like Mitchell Joachim from the Smart Cities Group, who believe we can literally ‘grow’ our homes right there on the house block With housing responsible for 20 to 35% of the environmental impacts of our private consumption, this is TV worth viewing. (We had an exclusive preview clip last week.) Or go to the online Your Guide for Greener Living for some other tips. ::Big Ideas for a Small Planet.
