Tree planting preparation (Sadhana Forest method)
Recycle material and use low-tech techniques to plant trees to: • Improve irrigation efficiency, • Improve young tree survival rate in harsh environment, • Rehabilitate the Dry Evergreen Tropical Forest (in this case near Auroville, India). Rehabilitation of the forest offers many other benefits such as soil rejuvenation, life-friendly microclimate development, biodiversity enhancement, water retention and so much more."If we could only understand what a tree does for us, how beneficial it is to life on earth, we would (as many tribes have done) revere all trees as brothers and sisters." (B. Mollison)

Solar coffee roaster (using a Scheffler concentrator)
It is about a coffee roaster that works with solar energy. The solar energy is collected by a Scheffler concentrator, a very good open-source technology, used since a while worldwide to cook.
