Army rations rehydrated by urine
newscientist.com ^ | July 2004 | Duncan Graham-Rowe

Would you eat food cooked in your own urine? Food scientists working for the US military have developed a dried food ration that troops can hydrate by adding the filthiest of muddy swamp water or even peeing on it.

The ration comes in a pouch containing a filter that removes 99.9 per cent of bacteria and most toxic chemicals from the water used to rehydrate it, according to the Combat Feeding Directorate, part of the US Army Soldier Systems Center in Natick, Massachusetts. This is the same organisation that created the "indestructible sandwich" that will stay fresh for three years (New Scientist print edition, 10 April 2002).

The aim is to reduce the amount of water soldiers need to carry. One day's food supply of three meals, weighs 3.5 kilograms but that can be reduced to about 0.4 kilograms with the dehydrated pouches, says spokeswoman Diane Wood.

The pouch - containing chicken and rice initially - relies on osmosis to filter the water or urine. When two solutions of different concentrations are separated by a semipermeable membrane, with gaps that allow only water molecules to pass through, the water is drawn to the more concentrated side.

Hungry soldier

The membranes are made of thin sheets of a cellulose-based plastic, with gaps between the fibres that are just 0.5 nanometres across, too small for bacteria to pass through.

A hungry soldier pours dirty water into one end of a foil sachet containing two inner pouches separated by the membrane. The water seeps through the membrane into the dehydrated food on the other side. As it dissolves large molecules in the food, it creates a very high concentration solution. The osmotic pressure created then draws more water through the membrane.

Hydration Technology of Albany, Oregon, which makes the membrane, says soldiers should only use urine in an absolute emergency because the membrane is too coarse to filter out urea.

The body will not find this toxic over the short term, says Ed Beaudry, an engineer with HTI, but rehydrating food this way in the long term would cause kidney damage.

They could have at least added "Filtered" urine to the title.

Ok, what kind of emergency would require pi$$ing on it, rather than eating it dry & crunchy?

I have been through dozens of cases of MRE's, I never had a problem with anything other than the tuna casserole.

I have about 50 of those bad boys that I will only eat after I eat my dogs.

Let me put it this way. I'd more likely eat something rehydrated by my urine than by someone else's.

This just might make the bottled water manufacturers a tad bit nervous. What if some chap brings to market a water filter shaped like a condom?

Gives the term 'fresh-squeezed' a whole new meaning ;)

I guess as a last resort you could use your urine if you were brave or fool enough to do it. Not me.

During the first GW we ate anything that required rehydration dry. It wasn't that bad and besides potable water was in pretty short supply for a while. Didn't want to "waste" it by rehydrating some of the sides that came in the MREs.

The only dehydrated meals that I can remember were the sausage and beef patties. They weren't too bad, just hard to choke down.

Cheers!

I see shades of mad cow disease, Soilent Green. By feeding cows other cattle floor sweepings is how that all started. It isn't "natural" to consume what nature intended the body to expell from its self as WASTE matter. Recycling works with non living material like metal, glass, paper, not consumption for living animals.

Confucius say: `he who cook carrots and peas in pot, very unsanitary!'

For real, our survival medicine course in Vietnam said you can cleanse an open wound with (your own) urine.

Yet another reason to `piss cold' when your unit is hit with an unannounced urinalysis.

But I agree, I'd rather eat the new ration dry crunchy.

I think that's why they call Coors Light "canoe-sex beer" because it's "f'n close to water".
