Urine and wastewater can be used as energy as they contain organic carbon, which the microbes in the microbial fuel cells effectively eat to survive. A microbial fuel cell is formed of two half-cells, each with electrodes inside.
One liter of urine can produce enough hydrogen gas to run an electrical generator for 6 hours. (A gasoline-fueled generator needs about 7 liters of that fuel to run for the same length of time.)
PEE POWER® is generated when microbial fuel cells (MFCs) work by employing live microbes which feed on urine (the fuel) for their own growth and maintenance. The MFC taps a portion of the biochemical energy used for microbial growth, and converts that directly into electricity or PEE POWER®.
It is NOT possible to be electrocuted by urinating on an electric fence line. The electric fence safety features preclude that. A stream of urine separates into individual droplets the further it goes. Because the urine isn't a steady stream, it would be unlikely that an electric current could travel up it.
By being put through an electrical circuit that the scientists created, these electrons create electricity. A good amount of electricity, in fact. Only two liters of urine can produce 30 to 40 milliwatts of power -- enough to slowly charge a smartphone, power a phone's display or power lights for portable toilets.
The urea found in urine is not in the proper concentration needed for DEF, nor is it of a sufficient level of purity, in either urea or water. The bottom line, to spell it out just one more time… urine and DEF = Never. DON'T PEE IN YOUR DEF TANK!
Drinking any type of urine can cause serious health problems unless it has been sterilized separately. Your urinary system specifically works to remove toxic substances from your body. When dangerous substances start to build up in your body, urine is one of the primary methods used to remove them.
Boil the urine and collect the steam on glass or plastic. The best way is to have two bottles and a long stretch of plastic tubing between them. Putting urine in one bottle and boiling it will push the steam along the tube until it condenses into drinkable water. NASA has another solution, and its simple osmosis.
How long can you survive by drinking pee? An extra day or two, at best. A healthy person's urine is about 95 percent water and sterile, so in the short term it's safe to drink and does replenish lost water.
Drinking urine will give you an extra day or two of survival. You can drink urine 1-3 times before it becomes too concentrated.
Is clear urine always a good thing? In most cases, clear urine is a sign that you're well hydrated. And that's a positive thing because good hydration helps your body function at its best. But, in some cases, clear pee may mean that you're drinking too much water and you're too hydrated.
Urine is non-toxic, although it contains urea and other substances which can be toxic if they are not excreted and reach high concentrations in the body. (Incidentally, something is either sterile or not.
The idea of urine therapy started around the 20th century. People claim that it works to cure some medical conditions, such as hair loss, it has been used in cancer treatment, for cleansing of the cardiovascular system, and to prevent viral and bacterial infections.
More often than not, they're caused by high concentrations of uric salt crystals, uric acids, and calcium that come from urine and/or the minerals in the water. After repeated use of the urinal, these uric acids build up inside your urinal's p-trap, creating a uric scale and choking your pipes.
Dog urine can corrode metal - Apparently allowing your dog to wee on a lamp-post could be more dangerous than you think - because the acids in the urine can corrode the metal.
No, AdBlue® does not contain urine
So, is AdBlue® made of urine? Not at all! The reason for this rumour is that AdBlue® is made of 67.5% demineralised water and 32.5% urea. However, urea is not strictly speaking urine, but rather one of its components.
It's the best way to reduce the risk of getting sick or spreading germs to others. Post-pee handwashing is even more important “before preparing food, touching your eyes, nose, mouth, or face, or caring for people who are at risk of becoming ill,” adds Newman.
Urine can be used as a fertiliser without fear it will fuel the spread of antibiotic resistance, researchers have revealed – although they urge caution against using fresh bodily waste to water crops. Urine is rich in nitrogen and phosphorus and has been used for generations to help plants grow.
Odor: If urine is kept for a long time at room temperature, it will give an ammonia smell produced by the bacteria, which will decompose the urea in the urine.
Urine is naturally antimicrobial; hypertonicity with low pH (averaging ~6.0) and high concentrations of urea inhibit most bacteria (Chambers and Lever, 1996; Kucheria et al., 2005).
Dark urine is most commonly due to dehydration. However, it may be an indicator that excess, unusual, or potentially dangerous waste products are circulating in the body. For example, dark brown urine may indicate liver disease due to the presence of bile in the urine.
Passing foamy urine now and then is normal, for the speed of urination and other factors can influence this. But you should see your doctor if you have persistently foamy urine that becomes more noticeable over time. This can be a sign of protein in your urine (proteinuria), which requires further evaluation.
A urinary tract infection (UTI)
Besides frequent urination, signs of a UTI include fever, a burning feeling when you pee, discolored urine and constantly feeling like you need to pee (even after peeing). You may also feel bladder pressure or discomfort in your back or around your pelvis.
Normal urine color ranges from pale yellow to deep amber — the result of a pigment called urochrome and how diluted or concentrated the urine is. Pigments and other compounds in certain foods and medications can change your urine color. Beets, berries and fava beans are among the foods most likely to affect the color.
