Overview
The theme of this edition is "Technologies that really work" and we are pleased to welcome Crispin Pemberton-Pigott as theme editor. Crispin is well known to many Boiling Pointi readers and has worked in the field of stoves for over 25 years. His editorial discusses changes that have happened within the household energy sector over the years and looks at what the future challenges could be.

This edition covers a range of energy technologies and looks at what has made them successful and used by people in Africa, Asia and Latin America. There is also a discussion around the issues needed to make a technology successful including the social, economic, marketing, environmental and political factors.

ITDG-EA pico-hydro project



Looks like a good way to power electric fanned stoves.

"The two schemes have brought electricity for lighting and small appliances such as radios and mobile phones to over 200 families (around 1,500 people). Villagers are very enthusiastic about the schemes, in particular the opportunity they give for children to study in the evening - exam results are said to have improved considerably."

Pico-hydro

Indigenous communities in rural Viet Nam, such as the Muong, often lack any form of power generation. This provides them with little opportunity to undertake practical and income-generating activities after nightfall. Recently, however, the Muong have adopted a form of hydropower, known as pico-hydro – the smallest scale of hydropower system. The kinetic power of moving water is transformed into electrical power by a turbine and generator. This gives the community valuable light in the evening and the ability to explore new technological avenues.

Smoke's increasing cloud across the globe
Practical Action June 16, 2006

Introduction:

It is in the world’s poorest regions that smoke is a major threat, including China, India and sub-Saharan Africa. On current trends, 200 million more people will rely on these polluting fuels by 2030. Women and children are exposed for up to seven hours a day to pollution concentrations 100 times and more above accepted safety levels. There is ample medical evidence that smoke from burning biomass fuels leads to killer diseases, such as penumonia, chronic bronchitis and lung cancer.
