About Howtopedia.org:
A collaborative platform for practical knowledge and simple technologies, (i.e. technologies that require no complex machine, that are easily explainable and usable by individuals or small communities) for a sustainable and ecological future […] We are convinced that sharing low-tech know-how across borders and organisations is essential for an independent and self-sufficient form of sustainable development.
