Today something interesting appeared in our newspaper : The "Lifestraw"
Athough the concept of a filtering straw is not new, this seems to be promising for a BOB:
reliable, cheap, simple, long lasting. You can supply one for every family member.
The product is being developped for third world countries. As a result it is simple and
cheap. It should (accourding to the newspaper article) cost 2.5 to 3 USD a piece. It can
filter max. 150 ml a minute. It should last for a year or 700 liters of water.
Other models with gravity feed wil be developped.
? shelf life?
Distribution should start 03/2006 (to third world countries, possibly not available for sale to individuals at startoff).
Pros:
- cheap
- long life
- simple, low tech
- 99.999% filtering
Cons
- not yet available.
- limitation max. 150 ml/min.
- only for "direct drinking" (other versions under development)
- not filtering

Might be interesting for some people?
Thanks to ETS and its members for the very interesting forum.
I learned a lot!
