Jason Livy if you are in touch with the Platypus folks please find out for us if they know of SODIS, and if the Platy water bags are usuable in this regard. If so, Platypus might think of using this to their advantage in advertising their product; thus helping themselves and being supporters of the SODIS projects <img src="/forums/images/graemlins/cool.gif" alt="" />

I'm tempted to email SteriPen too, since they should have tested all of the common containers with regard to FULL UV transmittance (Not just their stated UV-C on the website). The actual usability of our common drinking containers for solar disinfection - this is a really important question, or at least I want to know the answer!

Thank you Brum for starting this discussion, it's been interesting so far.
