Urine hydrogen power technology or the use of technology in nature. Because the chemical composition of urine contains hydrogen, hydrogen ratio in the urine to obtain electricity through water to obtain hydrogen lot less. Urea molecule is the main component of urine, which contains four hydrogen atoms and two nitrogen atoms. Will be a special nickel electrode inserted into the urine container, after the current will pass on to release hydrogen.
The researchers invented a prototype fuel cell small size of urine, could only produce 500 milliwatts of power. Their next goal is to achieve industrial production and widely used. It is estimated that a gallon of urine, urodynamic theory can guarantee to run 90 miles of fuel cell vehicles, a refrigerator-sized fuel cells in urine can produce 1,000 watts of power.
Chemists pointed out that the urine produced by a farm energy sufficient to maintain its normal operation. It is reported that in the United States for livestock farms are required to discharge waste treatment, this change in urine of new technologies for clean energy will undoubtedly made a double.
