That’s not what the article says. It says the new method “shows the POTENTIAL for revolutionising water disinfection technologies around the world” (emphasis mine). It’s talking about a method of creating disinfectants at the source rather than using chemicals. How to scale this up, deal with degrading catalysts, handle electrical demand, etc are all beyond the scope of an academic lab inventing a new method. They just demonstrated the potential.
If you read the entire thread from the top, you will see that you are making a point that has already been acknowledged by everyone contributing to it. Bringing it up again merely loops the discussion back to a point where it has been before.
The fact that they are making bold claims about potential applications is sufficient to justify Kaibeezy's reply to riddly.
