Kudos to Nanotech: The Instant Drinking Water Filter

Posted on August 5, 2009 by


Now this isn’t mindless marketing for some other new water technology. This is simply bad, real bad Michael Jackson.

When I was entertaining thoughts of an anarcho-primitivist lifestyle relying on mainly hunter-gathering, the first thing that came to mind was about how to get water. The second thing that came to mind would be how to filter that water.

I would be at loss to build a reverse osmosis system out of raw materials. I’d probably create some kind of slow sand filter, which would probably barely filter anything. I don’t know what the fuck I’d do if I had to hustle up water during some kind of public health crisis.

With an eye towards the public health crises of the Indian Ocean tsunamis of 2004 and Hurricane Katrina where people had to drink contaminated water, some British guy named Michael Pritchard came up with the idea of an instant water filter.  An instant water filter manifested in the form of a water bottle with a pump.  The pump forces the water through very small membranes that filter out not only 200 nanometer bacteria, but also 25 nanometer virii with its 15 nanometer pores.

This is one of the few times where I will say, science and technology wins.

This is like the iPhone except for actual useful, basic human needs. It’s a handheld technology that you could actually use in any context without relying much on any visible public infrastructure.

At the product’s performance, I wondered how he came at the figures 6,000 liters or 3 years before it would need to be replaced. I assume it’s because the 15 nanometer pores begin to erode and get wider. The next question that should be addressed should be how to make materials that hold up those pores buckypaper strong to last beyond 3 years.
