Urine turned the fuel cell
Urine turned the fuel cell
U.S. scientists recently used a new technology, so that urine can power cars, appliances and other equipment can also provide energy.
Scientists are using nickel electrode can be extracted from the urine and a large number of cheap hydrogen, and hydrogen can be used as vehicle fuel or used to make fuel cells. According to reports, a cow's urine for 19 families to provide adequate hot water energy.
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.
JA Solar solar prices plunge, the stock fell 8%
4.12, -0.35, -7.86%: JA Solar HoldinGS Co. (JASO) shares fell 7%, this solar energy companies in Shanghai greatly reduced second quarter net profit 51%, accounted for in the cost of including a net loss of earnings. The company also pointed out that the battery in the second quarter inventory increased, and the solar cell prices dropped. JA Solar forecast in the third quarter average selling price fell 5-10%.
Pay attention to the quality of electric vehicle batteries to buy
Golden Branch of Xishan District Consumers Association has revealed that the complaints received in its electric bicycle battery, half the quality of complaints.
From the complaint situation, some manufacturers malicious competition, play in product sales "price war" in cutting corners in production, the use of cheap low-quality batteries to reduce costs. Some electric car battery maintenance sales staff neither the expertise nor the professional testing equipment. Some businesses will Banjiu battery in appearance to 'technical treatment' after posing for a new battery to consumers.
Consumers to buy electric bicycle battery can understand some of the knowledge in advance. For example, the regular appearance of a clean electric bicycle battery, internal and external signs clearly visible. Best Buy has the rated capacity marked on electric vehicle battery. Battery "three" is the obligation of operators of electric bicycles, in the "three guarantees" the battery fails within the time limit, operators, producers should bear the "three guarantees" responsibility. In addition to the length of battery life and battery on the merits of their own quality, but also the correct use of the consumer. Not one-sided pursuit of cheap, buy low-quality electric bicycle batteries.
