(This CD-Rom contains all the back-issues of Boiling Point with an extremely good search facility)
The CD-ROM Humanity Development Library 2.0 for Sustainable Development and Basic Human Needs contains the equivalent of 160000 pages/340 kg/20000 US$ worth of useful books and newsletters on this single CD-ROM of 25 grammes.
The goal of the non-for-profit Humanity Libraries Project (formerly known as Humanity CD-ROM Project) is to provide persons in the South with access to a complete basic library on CD-Rom of about 3000 essential books at the lowest cost possible. The initial language is English, soon other languages will follow.
The CD-ROM immerses the user into thousands of ideas and solutions for basic needs and sustainable development. The first priority is to create a critical mass and to distribute 50000 of these (six-monthly updated and improved) CD-ROMs out the following 6 months. We envisage, as long as possible, to keep the price for NGO & humanitarian users in developing countries extremely low (preferably around plastic costs): 6 US$ per CD-ROM + delivery costs, if you buy at least 40 CD-ROMs. There is a sponsor formula for Western organizations, businesses or individuals; we propose a yearly sponsor subscription of 100 to 200 US$. This includes getting all updates and either 5 or 10 discs a year for redistribution through your channels.

Firewood substitution by kerosene stoves in rural and urban areas of Nicaragua, social acceptance, energy policies, greenhouse effect and Financial implications.
Henk Alberts, Celia Moreira and Rosa Maria Pz.
A paper has been published in Energy for Sustainable Development, vol iii, no 5, 1999, describing a feasibility study on the demand and consumption of firewood in Nicaragua through a massive fuel switch towards kerosene. A locally-based foundation distributed 700 high-quality Chinese kerosene stoves, using a credit scheme, both in a rural village and in a suburb of the capital. Surveys of family fuel consumption were carried out before the intervention and one year after the intervention.
The population's acceptance of the stoves was very high, evidenced by
· the high percentage of delivery of the stoves to the biomass-using population
· the highly enthusiastic response of people recorded during visits
· the high usage rate of the stoves (80%)
· the overall decrease of 50% in the use of firewood for the involved area.
· offering an alternative source of fuel is a feasible, cheap and appreciated solution to deforestation.
· projects using these methods could potentially lower firewood consumption at the national level by 50%.
· local organizations are capable of implementing this strategy on a wide scale
· the economically less favoured classes of the population can be reached without any major constraints, leading at the same time to important positive effects on health.
· the costs per tonne not emitted carbon, through this strategy, is calculated at 1.7 US$/tonne.

New 'Capturing Heat' publication
Aprovecho Research Center has just published the second booklet in its 'Capturing Heat' Series. This new booklet describes how to design inexpensive appropriate technology type wood burning stoves with chimneys to optimize both more complete combustion and better heat transfer to the pots. Insulating the entire fire flow path and combustion chamber helps to achieve cleaner combustion. Exposing as much of the pot as possible to the high grade heat can reduce fuel consumption considerably.
The booklet also explores fuel efficient bread baking and analyzes the difference between high and low mass ovens. The retained heat oven can be very wasteful of fuel because only heat at a certain temperature is useful for baking. As well, the mass of the oven should be sized to the amount of bread to be baked. Low mass ovens that heat air and bread directly can save very significant amounts of firewood.
