NASA's New Bag Turns Urine Into Sports Drink
An anonymous reader writes "NASA's Atlantis shuttle is set to launch this Friday, and its crew will be testing an innovative device that can recycle human urine into a sugary sports drink. The bag uses forward osmosis technology and features a semi-permeable membrane capable of isolating water from virtually any liquid. Recycling urine in this way has a significant effect on a ship's payload, and considering that a single pound adds $10,000 of cost, that slight weight difference can translate to serious savings."
CT: I'm at Kennedy Space Center now, tweeting as @cmdrtaco. And I think I'll stay away from the sports drink.
I bet they could have gotten away with just a regular plastic bag.

Piss was already a sports drink.
I got here through a series of tubes
It IS in you...
NASA has given us one of the major components required for a functioning stillsuit. Thanks, NASA!

Gatorade. Was it in you?
Assuming it can filter out a bacterial infection in piss so will it work to make sea water drinkable?

With the realization that effluent from sewage plants has detectable amounts of antidepressants, estrogen (from birth control pills), and other modern drugs which may be impacting river life, I'd really like to know that this membrane stops those (as well as "virtually any liquid"). I'd hate to spend a couple of months in space and find that I now had breasts due to water-transported hormones from the women on the crew...and that they'd grown muscles and body hair due to mine.
Add one redneck and you have a perpetual (quasi) beer machine.

I have a well for my house, with a commercial reverse osmosis filtering system. So no, I don't realize that.
Aside from that, most of the cities around me get their drinking water directly from Lake Michigan. The 'sewage' that you mention gets treated and sold as 'soil' at the local home improvement store after being mixed with sand to prevent clumping. The fluid component also gets treated and sent off to agriculture where it is used as fertilizer. Any other reclaimed water is used mainly for irrigation or industrial uses, and not drinking water.
You only have a surface understanding of these processes, and it doesn't apply to very many actual cities, and millions of people. In actuality, there are probably only a few thousand people in the US who directly get drinking water from treated sewage like you describe.
