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."

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. [http://www.solare-bruecke.org/index.php/en/die-scheffler-reflektoren This page explains the working principle of the Scheffler concentrator.] The solar energy enters directly in the roaster, where the beans are placed. We can roast coffee beans (around 230°C), cacao beans (around 160°C) and even make pop-corn !…

The Japanese way of coffee making is a process of creation, without needing to use fossil fuels. That's why we decided to put this concept in a module for cargo bikes, in the idea to transport more than only resources.--by Canal d'accroche
