Watermelon juice can make bio-energy
American scientists recently declared that watermelon juice can be the latest source of renewable energy for automobiles. This discovery will make biofuels more and more widely used worldwide.
About one-fifth of a year watermelons are discarded by retailers due to malformations or broken skins. In the 2007 growing season, about 360,000 tons of watermelon was wasted in the United States alone. Now researchers from the U.S. Department of Agriculture say that these unsightly watermelons can be used as biofuels. Scientists point out that the sugar in watermelon can be fermented into ethanol, which is the so-called drinkable alcohol.
Ethanol is a clean energy source, mainly from food and sugar crops. The watermelon juice in a watermelon accounts for about half of the weight, and watermelon juice can get 10% fermentable sugar. In the experiment, scientists found that it was possible to convert sugar from watermelon juice to ethanol. It was estimated that about 26 liters of ethanol could be extracted per ton of watermelon.
Compared with other crops, the production of ethanol through watermelon juice has a great advantage, that is, it can greatly reduce the use of water, but also can provide the nitrogen needed for fermentation, but watermelon itself can not solve the huge fuel needs of the entire country, just play a supplementary role . Experts said that the wasted part of other crops can also be converted into fuels, such as Mexican agave, which can be used for wine making, and the sugar content is very high, so people in the deserts of Mexico and the U.S. can make full use of tequila. Bioenergy.
Oklahoma Agricultural Researcher Wayne Fish (Wayn Fish envisions building a mobile fermentation system, from farm to farm, like a mobile junket machine. Some farmers can brew alcohol to solve their daily fuel needs At present, a biofuel company in Texas, USA, is manufacturing such a mobile machine.
PU Floor Profiles are widely used to decorate at the foot base of the wall.
Without PU Floor Profiles, the transition from floor to wall looks unfinished and bare and allows walls to be easily damaged. Skirting board is more than just decoration.
