As you know TED Talks has lots of interesting lectures and I found these two that are espefically interesting for our studio. If have time take a look they are about 20 minutes long.
http://www.ted.com/talks/carolyn_steel_how_food_shapes_our_cities.html
This one is about how food travels and the consequences of the processes involved in it.
http://www.ted.com/talks/william_mcdonough_on_cradle_to_cradle_design.html
This one is from the author of the book cradle to cradle, he introduces the main ideas of the book wich are all connected to recycling and cycle in general. He criticises the way we live today and gives some examples of design concepts that could help change that.
Hope you enjoy it.
And for those of you who are not in the Solar Energy Seminar, next week they will post the lecture and some useful links about solar energy that are very useful for our design.
