Wonder if the article considers the effects of sun ultra-violet radiation to help in that process.
Such temperatures are common in sous-vide (see e.g. http://www.douglasbaldwin.com/sous-vide.html - interesting headings to grep include "Pasteurized in Shell Egg" and "Computing the Destruction of Pathogens")
Though this does sound neat, and it's still much better to have than nothing at all.
It's like the old saying, it's easy to destroy HIV - the hard part is doing it inside a human body. In the case of sterilizing water, we don't have that problem, the water will remain usable.
So, 150 °F is not really all that hot as some organisms thrive at 250°F or well above boiling. However, I suspect organisms that thrive at 150+°F are unlikely to also thrive in the human body. A more important issue is the effort to sterilize water by hand is unlikely to be made with any real consistency.
That's what safety margins are for.
Point? Entropy is a bitch, but mankind carries a bigger stick.
For everyone who's saying that nothing could evolve to resist this, please look at Legionnaire's disease: http://en.wikipedia.org/wiki/Legionnaires'_disease
This is a disease which can be fatal, and is found in association with systems involving water, including hot water heaters.
I'll grant you as much as you likely that you're unlikely to get this or that, what I'm cautioning against is the idea that you've found a silver bullet. You've never found a silver bullet against bacteria, and it's better to go into use of systems like these with that assumption.
Thinking ahead to make "thoroughly rinse, clean, and dry this system at least once a week" part of the instructions for use as a precaution against bacteria isn't nay-saying, it could be quite valuable to the people we would have using systems like these in the future.
Our only hope, is all I'm saying, is in our ability to cross all boundaries and communicate under extraordinary duress, nevertheless, with effective results. So I fully support your position.
I'm encouraged by the community efforts being made to address this; there is, after all, a very large industrial powerhouse that can be directed towards these problems. If we see Ebola-bots on the horizon, better hope they're flying away and not getting closer, uh oh ..
