Ally Zak Z. sends email via satellite from Puntamona in Costa Rica, "perhaps one of the most ecologically sustainable living experiments around. completely off the grid, totally solar, growing its own food, living well...." Sounds like another stop on the Worldchanging world tour, when I get around to taking it.
Talking about the Worldchanging world tour, I am planning exactly something like that. I was just about to go through your archives. Any recommendations very welcome. I'll start in South-East Asia.
