It has become apparent that most wood-burning stoves used in developing countries are very 'inefficient'!
That means that they produce a great amount of smoke that has three serious effects:
1. It produces many serious lung diseases in the families of the users.
2. The black smoke produced by millions of stoves considerably increases global warming. (Ask us for references)
3. Far more wood is burnt than really necessary.
This being so we have carried out experiments on stove insulation and am arranging that similar work is carried out in Africa.
If you know someone who might be useful in this field do let us know!
We offer instructions for making a DIY Solar Cooker from cardboard plus Mylar or foil or any shiny metal!
