1 - There is already something similar to this. I don't know the details, because I only heard about it quickly in the radio here in Brazil. Some US or Canadian company already has something similar ready, but for sugarcane instead of wood. They had development fase close to completion, starting planning for eventual production.

2 - Rain Forest? In Patagonia????? Sorry if my english sucks, but as far as I know, Rain Forest is a tropical forest. Patagonia is in the southern extreme of South America. That's temperate to polar Climate!!!!!
