HI, there
http://www.worldchanging.com/archives/007106.html talks about a gathering at MIT to develop technologies to cheaply meet needs in the developing world.
The International Development Design Summit, as it was called, is at:
http://www.iddsummit.org/
The inventions mentioned are:
a electricity-less fridge, an oven (that produces less smoke), a greenhouse, and a water-transport solution entailing cheap solar-cleansing ergonomic pouch-clothing.
With greater connections established between villages and the developed world (through the $100 dollar computer and the like, for example), problem can better meet solution in the future.
Engineer a better world!
transporting water
1. I'm thinking water can be transported through pouch-clothing and aqua-trikes.
2. The aqua trike could even haul a trailer, that carries more water, to be purified later, I spose.
3. Paths between village and water could be made into bike paths.
4. I don't know if this would help, but as a Boy Scout, I was taught about a survival method to obtain water using a tarp laid over a pit to collect ground condensation. It also needs a tube, if I recall correctly.
Cleaning
5. Does soap harm the environment? Are there ecological soaps for rivers and such?
See toxic soap and ecological soap or cheap nontoxic detergent.
