hmmm, @JASONGNC: UV water treatment units tend to contain immobilised titanium dioxide (the pigment used in white paint). When this is irradiated with
UV light, short lived, highly reactive species are formed from dissolved oxygen which kill microrganisms within the water.

The same principle is used with self cleaning window glass - sunlight causes a thin coat of titanium dioxide to produce the same species which then break down grease and grime on the pane.

Not that this water making machine doesn't sound like a complete con to me in general

Surely "more affordable" is legitimate even if the price ends up a bit higher? I may not have all the money available today, but I could still afford to get one.

Subsidy to get rid of the up front cost, paid for by the monthly contract is how mobile phone usage was able to expand in the first place (it's even there in many pay as you go deals)

In any case, we seem to be doing alright here in the UK once you get over having to move to O2. I think we're going to get it more affordable and cheaper than the last one.

We used to use one of these in the desert - you can't do much else in soft sand.

Why would it be any more dangerous to a drunk than a standard jack?

In the UK it's illegal to sell a drunk person alcohol. Is there any great difference here?
