from CNN.com - 'Astronauts' sweat provides water for drinking'

file under fascinating, and potentially life-saving, along with weird: this article from CNN.com: "Astronauts' sweat provides water for drinking."
Yep, that's right. Apparently, this system has been in process for NASA astronauts that would use sweat, respiration, and even urine to provide drinking water - pure drinking water, after it runs through this system being created. It isn't ready for space yet, but some groups are looking into using it on earth sooner than later - to provide, for example, clean drinking water for tsunami victims.
Fascinating.

An excerpt: "The Marshall Space Flight Center in Huntsville, Alabama, has been testing a device intended for the space station that would recycle astronauts' sweat, respiration and even urine into drinking water purer than any found in a tap.
"They just breathe and exercise, urinate into the urinal and our system handles the rest," said Robyn Carrasquillo, chief of the environmental control and life support division at Marshall.
It could be two years before the water system -- as large as two refrigerators -- is loaded onto a shuttle to serve an American astronaut and Russian cosmonaut living in space. But smaller and simpler versions will soon be put to use on earth.
Reno, Nevada-based investment firm Crestridge and the charity Concern for Kids are developing the systems for humanitarian purposes in nations lacking a reliable water supply, starting with Iraq and countries in southeast Asia.
"There are 1.8 billion people who have never had a drink of fresh water," said Kevin Chambers, Crestridge's managing director. "Our mission is grand, but we've got to start somewhere and sometime -- and now is the time."

Sermon for Second Sunday in Advent, "Peace: All Is Calm, All Is Bright," Isaiah 11:1-10, Mark 13:24-37

Sermon 12/3/17 Mark 13:24-37, Isaiah 11:1-10 Peace: All Is Calm, All Is Bright             “Silent night, holy night. All is calm, all is bright. Round yon’ virgin mother and child. Holy infant, so tender and mild. Sleep in heavenly peace. Sleep in heavenly peace.”             This week, I read news stories about North Korea testing a missile that perhaps could reach across the whole of the United States.             This week, I spoke with a colleague in ministry who had, like all churches in our conference, received from our church insurance company information about how to respond in an active shooter situation. She was trying to figure out how to respond to anxious parishioners and yet not get caught up in spending all of their ministry time on creating safety plans.             This week, we’ve continued to hear stories from people who have experienced sexual assault and harassment, as the actions, sometimes over decades, of men in positions of power have been

Sermon for the First Sunday in Advent, "Hope: A Thrill of Hope," Mark 1:1-8

Sermon 11/26/17 Mark 1:1-8 Hope: A Thrill of Hope             Are you a pessimist or an optimist? Is the glass of life half empty, or half full? My mom and I have gone back and forth about this a bit over the years. She’s wildly optimistic about most things, and sometimes I would say her optimism, her hopefulness borders on the irrational. If the weather forecast says there’s a 70% chance of a snowstorm coming, my mom will focus very seriously on that 30% chance that it is going to be a nice day after all. I, meanwhile, will begin adjusting my travel plans and making a backup plan for the day. My mom says I’m a pessimist, but I would argue that I’m simply a realist , trying to prepare for the thing that is most likely to happen, whether I like that thing or not. My mom, however, says she doesn’t want to be disappointed twice, both by thinking something bad is going to happen, and then by having the bad thing actually happen. She’d rather be hopeful, and enjoy her state of

Sermon for Fourth Sunday of Easter

(Sermon 5/3/09, 1 John 3:16-24, John 10:11-18) Love Letters from John: The Good Shepherd When I first started preaching here and there when I was in college, I would take a look at the texts from the lectionary, the schedule of scripture readings for the Christian year, and try to find the common thread between the texts, try to find a way to make them go together. Each week there are four suggested scriptures – An Old Testament reading, or a reading from the Acts of the Apostles, a Psalm, a New Testament reading, and a reading from the Gospels. But eventually, as I gained more experience in preaching, I realized that it was certainly easier, and often more effective and meaningful, to focus in on a single text. After all, there is certainly enough in most individual passages to make an entire sermon or two. But occasionally, still, the texts for the day go so perfectly together that I feel like we’re missing out if we don’t look at how the texts play off of one another, how
