Does anyone know what happened to the proposal by an African scientist to provide refugee camps in Zaire with efficient small ovens that could be mass produced from scrap metal in a nearby town and that would reduce the burning of wood by a huge percentage?
I have not heard of such ovens specifically in relation to refugee camps in Zaire but work is being carried out in Kenya by Doctor Daniel Kammen of Princeton University and Monique Nditu of the African Academy of Sciences into the use and supply of similar ovens. Their work is based on the thesis that people in Majority World countries rely on wood for over 50 per cent of their energy needs, and their forests are coming down as their populations rise. Solar power, wind power and other renewable energy sources seem like the obvious solution to the problem, but they have rarely been put to the test. Three years of successful fieldwork in Kenya has examined whether solar ovens and windmills can both fulfil the Kenyans’ energy needs and fit in with their society. A major goal of this project is to develop a training centre for research into renewable energy and the environment that will serve researchers and community groups from all over Africa. Workshops are held in which Kenyans adapt and construct solar ovens and, in follow-up studies, chart the impact of the ovens on household economies in local villages. These highly successful workshops have spread to other Majority World countries.
Volunteers and funding for the project comes from Earthwatch.
I note that Scientific American magazine has an article entitled ‘Cookstoves for the Developing World’ in the July 1995 issue (pp 72-75). Perhaps the scientist the questioner seeks is within that article?
Given that the profit from slave labour in today’s terms is a staggering $187 billion, are there any legal precedents for this money to be repaid in some way as a legacy to the living descendants of such slaves?
Many societies from before – and including – the Romans have been involved in the slave trade. Therefore, allowing for inflation, the sum of $187 billion seems a bit low. I would suggest the effort put into worrying about slaves in history should be redirected towards the problem of slavery in today’s world.

Is it ‘proven’ that long-lived creatures carry the same, unaltered DNA throughout their lives – or is this just an assumption?

How are features added on to a globe? I can think of no convincing way that complex images could be printed directly onto a sphere without distortion or numerous joins.
Is there an organization that collects medical goods (not drugs) past their expiry date?
At work we use the term ‘Spanish custom’ when highlighting the use of a procedure that has not been documented in one of our many rule books. Where has the term come from?
