We headed further south through Virginia on I-81, stopping at the Radford Rest Area. I love rest areas. I must have passed out campaign cards to people from at least 10 different states. At one point in the campaigning, after several cups of coffee that morning, I had to, well, urinate. And that’s another thing that’s great about rest areas, there’s a readily available place to, well, urinate. Turns out, not only were urinals readily accessible here (that is, after several truck drivers got through), but these urinals were also rather unique. They were no-flush “Sloan System Urinals.” According to a sign above the urinal, which you inevitably have time to read because, I mean, you’re just standing there, one Sloan urinal saves 40,000 gallons of water a year. There apparently is a cartridge at the base of the urinal that collects uric acid from your urine. The remaining liquid, which is not corrosive, then just flows down a pipe. Whenever I urinate, I always feel better. But this all made me feel doubly better. (If my wife Liz knew I was writing the blog entry like this…) I recently gave a talk at Notre Dame University. During the talk, I noted that some one-sixth of the world’s people don’t have access to clean drinking water. What’s more, we’re increasingly polluting the fresh water we do have. But with much more of this new sustainable water technology, we could begin polluting way less, and saving money to boot. Money that could be funneled into Developing World clean water projects. Note: The late Pope John Paul II once said that economic justice is about considering the universal destination of the earth’s resources, especially in regard to the “common good for society’s weakest members.” Translated, those of us in the Developed World, must do everything we can to get clean water to our brothers and sisters who don’t have clean drinking water. And there are tangible steps we can take to do that.
