If you are a hiker or camper, you may have heard about Vestergaard Frandsen’s LifeStraw. It’s a hollow stick equipped with a series of filtering membranes. You put the end of the stick in a river or puddle ─ or a toilet, for that matter ─ and suck on it. By the time the water hits your lips, it is clean and safe ─ its filters are fine enough to trap virtually all bacteria, viruses and parasites. The product has a bigger cousin called the LifeStraw Family. You hang it on your wall, pour dirty water in the top, open the tap and clean water comes out the bottom. No power or replacement parts are required. Each unit cleans about 18,000 liters of water ─ enough for a family for three years. The market cost of the unit averages out at a penny per ten liters of water purified.
Vestergaard Frandsen will distribute the LifeStraw Family for free. It is helping to sponsor a traveling campaign through the western part of Kenya set for April, 2011, that will reach 4 million families. The campaign bundles various products ─ each family that attends will get insecticide-treated bednets to protect against malaria, AIDS tests and counseling and a free LifeStraw Family.
Louise Phinney on 25 Feb 13"Unfortunately, I've come across a number of resources which only focus on the negatives of digital footprints and promote a culture of fear. The message I like to promote is that we should protect our digital footprints and try to ensure that they are positive. Encouraging students to avoid posting or doing anything online just seems counter productive."
