SolarOSE - Solar concentrator for steam generation
An open source solar concentrator to provide thermal energy for many applications. This document describes the construction of a linear Fresnel solar concentrator. The prototype is adapted for heat needs between 100°C and 250°C. Current levels of energy consumption are generally unsustainable. The use of solar energy favors a better distribution of the territorial economic activity. Meanwhile, many actual models are either designed for the industry, either for cooking in the South countries. Open Source Ecologie France researches and develops a solar concentrator made for an intermediary market, in order to make possible for little producers, artisans and micro-industries the use of solar energy.

Showerloop: Water filtration and purification system
Showerloop is a water filtration and purification system that recycles shower water in real time allowing you to shower with hot water for a long time but only use 10 liters of water per shower (normal shower = ~6-10l/min) and a fraction of the energy (around one tenth) compared to a normal shower. The device can be installed inside or outside of a shower stall or bathtub. The main components are a pump, sand and activated carbon filters and a UV-lamp. The system weighs around 20kg and is made from transparent acrylic, steel or plastic pipe connectors and copper, plastic or rubber tubing.

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. [http://www.solare-bruecke.org/index.php/en/die-scheffler-reflektoren This page explains the working principle of the Scheffler concentrator.]
