This is now very old technology. As has been said, this is already well used all over the world in water treatment, but in quite a different form than is used in this bottle.
Hair dresser and other beauty industries us a similar technique to this, BUT will also tell you that they do not work well if the item to be sterilised is not rotated (so this or any other water treatment bottles need to be moved or rotated to work effectively). So, as has also been alluded to, this system will not cope well with dirty water for the reason above. In fact, this technology is now so widely available, that even Philips provide ultra violet sterilisers for their tooth brushes.
I guess any award for this product will reflect its wind up system (which is an advantage, and if reliable, a lot better than battery power). It will of course suffer from all of the disadvantages of any 'one bottle' filter or steriliser, in that it becomes less adaptable in use.
Edited to add:
As the report makes great play on just how fast this bottle is in use, and quotes some other ways taking at least 30 minutes (which is true for one of them), it may be worth pointing out that with a system like the 'travel tap' you could fill your bottle, drink the contents. Fill it again and drink the second lot of water. then fill and drink it again in less than 90 seconds!
Just adding some balance to the high speed claim.
