"Lifesaver Bottle" Filters Viruses Out of Water 503
gihan_ripper writes "British inventor Michael Pritchard has developed a small self-contained filter system that instantly cleans water, removing all particles larger than 15nm. He said that he was inspired after seeing the effects of Hurricane Katrina and the Boxing Day tsunami in 2004; people had to wait for many days to get fresh water and many died from drinking contaminated water. The filter is so effective that it can purify dirty river water and even fecal matter. His bottle will shortly be available for sale from Lifesaver Systems at an expected cost of £190 (approx. $385)."

Difficult to do when there is no bus drivers, or no electricity to pump gas or run the airport. You forget the largest problem in Katrina was getting to the people, and getting the people somewhere safe, among other local government problems.

It it sees widespread production, the cost will go down (economies of scale) and advances in materials science and manufacturing techniques could also get the price down. Eventually.

Fantastic idea, except for the fact that anyone in the path of Katrina who could have afforded a $385 water bottle could have afforded a $90 plane ticket, $35 bus ride, or $27 tank of gas.
Easier to hand out one bottle per person than one gallon of water per person per day. You also fail to note that there were mile-long lines at the pumps, and flights and buses were full. This is in part due to infrastructure, part due to the realities of evacuating a large city, and partly because the evacuation order was given ridiculously late.

Presumably it's disposable, and considering that it's probably the bulk of the cost, the whole bottle would be disposed/recycled at the end of its usefulness...which I might add is projected at 4,000 - 6,000 liters of filtered water, according TFA.

If this can deliver 4,000 liters at under $1 a liter, and is shipped empty, it's cheaper than shipping pallets of bottled water for military and aid organizations. And when mass production hits, I can see this becoming popular with campers, tourists, business travellers and others.

I wholeheartedly agree, but they don't remove suspended solids or do much to remove odor (other than to perhaps mask it).
Something tells me that the marketing point of view was taken to draw more attention to the product ("hey, look! this can save lives!") rather than selling it on where most of the buyers are going to be, the military and extreme outdoors recreationalist types.

And on that subject, jackasses like this [bbc.co.uk] are why it's hard to help anyone:
Of course, if "there is decent water resource management in the country" in the first place, none of this would be necessary. And never mind that if I'd have to make a trek for water anyway, I'd prefer it to be clean when I got there.
If the LifeStraw at $3.00 will actually hurt women and girls and not solve the rest of society's ills, I can only imagine what Mr. Hetherington would think about a model that cost 100x more.
Price gouging (Score:2, Insightful)
People would get safe water that way.
But it would be price gouging, so it's illegal. Better people die from drinking polluted water than someone make a few dollars helping them. That's the rule of price-gouging laws.

What does this thing do with gasoline, pesticides, and other chemicals coming out of drowned cars, stores, homes, and factories? If it isn't removing these chemicals, then you can't be sure the processed water is safe to drink. You will probably see a lot of sick people who relied on this product, and got poisoned because of the false sense oc security.

This isn't a micron filter. A micron filter has pores a few orders of magnitude too large to filter out viruses.

Obviously, they are related because the levees would not have broken without the hurricane. But the point here is that the Hurricane did remarkably little damage on it's own. The levees, on the other hand, were responsible for almost all of the issues you read about today.
Just another example of the edges starting to fray with respect to our national infrastructure. Without the levee issues, Katrina isn't special. Powerful? yes. Scary? yes. Destructive? Not really, when compared to something like Andrew or Hugo.

I'm thinking that, for £190 one could buy many hundred liters of bottled water. Considering a person requires about 2 liters daily for drinking, cooking, and toilet use this is about a month's worth for a family.
Besides, if you're without clean water for longer than a month, it might be a clue that it's time to take your family and leave.
