For Saul of Tarsus, it was traveling the road to Damascus. For John Barrie, it was a trip to Ecuador in 2004.
John, a well-known and successful green architect and industrial designer, was looking out of the window of a bus.
"I do solar design," John said. Looking out at the homes, "I realized that if you rearranged the materials [wall and windows] you could make buildings that were much more comfortable in which to live. You could be comfortable during hot days and cold nights.
"My training put me in a position where I could do something. No one was designing things for poor people. I can do this."
Thus was born the Appropriate Technology Collaborative.
