Makes me wonder if an un-discussed benefit of a hydrogen economy (other detriments and benefits aside) might be an increased availability of purified water. I don't know if H2O coming out of a typical H2 fuel cell is necessarily clean, but maybe it is?
I have used Brita in the past, and am using a similar Waterpik now. Both are of the type you warn against. I noticet that both seem to waste a fair amount. When you first put the filter in, you have to run it for a gallon or so to get it going. With the Waterpik, over the 200 gallon life of the filter, it seems you're supposed to run it a little each time until the green light comes on and then the water is ready for you to take. So, what you run before the green is waste I guess. And all the energy and effort it took to get that waste water to your house and purify it somewhat... I'll keep an eye out for a better system.
