Feature
The topic of water filtration
and purification that was covered here a while ago
has led to another area of DIY investigation. Many women in
the developing countries spend much of their time and effort
in collecting water and firewood, but if they were introduced to the use of low-tech solar
ovens and/or high efficient
woodstoves their
lives could be made a little easier.
As a Citizen Scientist,
your challenge would be to design a system that is:
- … better and/or more efficient
than the “old” ways.
- … inexpensive or of zero cost.
- … made from locally obtained materials.
- … DIY and user repairable.
