Solar bag - maybe use for purifying on expeditions

[Aushiker]

This has popped up at Gizmag; it is called a Solar Bag. It looks like it could be option for bicycle touring or maybe more for expeditions.

However, while PET bottles can usually only purify up to three liters per every six hours of sunlight, the Solar Bag's makes claim that its combination of high clarity polyethylene and black polyethylene allows the device to purify 2.5 gallons (9.4 liters) in the same time-span, and that it will start working on the purification process while still being transported. These two differences could potentially save lives, making the Solar Bag project an exciting prospect, even in this early stage of development.

Mmmmmmm, I'd still use my trusted Katydin micro purifier
If its good enough for UNESCO and the Red Cross then it's good enough for me

I second that Brains.If you need water you need it there and then, not waiting around for it to purify. The Katadyn was £££ but do the job well.

Not necessary the case on "expeditions". Riding in parts of Western Australia you will be carrying water for days, not accessing daily from a water source.
