According to the U.S. Institute of Texas, an agricultural research company, in the manufacture of bio-ethanol at the same time requires a lot of water, and watermelon can not only provide sufficient ethanol, can also provide enough water to participate in reactions. Through the watermelon market survey found that, in the United States each year, 36 million tons of watermelon due to be sold while the rot in the fields, these watermelon enough to make 2.5 million gallons of ethanol.
The institute said that from the results of the experiment to see, watermelon is comparable to high-sugar crops, corn and honey, one of the sources of ethanol fuel, which means that the United States, watermelon growers who do not have to worry about the future of at least sell a watermelon.
Forget chip fat, sugar cane or rapeseed oil – the latest source of biofuel could be watermelons.
Scientists have discovered that the fruit is a great source of sugar that can be readily distilled into alcohol to power cars and farm machinery.
Sweet, juicy watermelon, fresh thirst-quenching, life is a popular summer favorite fruit. U.S. scientists have discovered one of its new role, watermelon also can produce ethanol fuel, which is a renewable energy.
Annual harvest season, the total number of watermelon due to skin damage or skin "abnormal" by retailers dislike. Research team led by the U.S. Department of Agriculture Weienfeishen study these discarded watermelon juice is a potential value in use. United States Fish Science Daily Web site quoted as saying: "We found that the watermelon juice can provide easy to ferment sugar, these elements so far not been used to make ethanol fuel."
The researchers said that from the Guardia per hectare, where the rest of watermelon can be extracted about 76 liters of fuel. Ethanol is a clean energy, mainly from grain and sugar crops. Some local Guanong leftover melon can not create ethanol for fuel skepticism. But the fish and his colleagues through a series of experiments show that watermelon can indeed produce ethanol.
Fish the team calculated that a year can make use of waste produced 9.46 million liters of ethanol watermelon.
In 2008, the nation\'s corn and other crops produced 34.1 billion liters of ethanol. In contrast, watermelon can provide bio-fuels is only a small part.
However, the process of producing ethanol with corn and molasses need plenty of water, and sometimes fermented to add nitrogen will also be required. Watermelon juice through the production of ethanol can significantly reduce water use, can also provide nitrogen needed for fermentation, if the watermelon juice, or molasses added to a mixture of corn, you can make these bio-fuel raw material to save 15%. According to Xinhua News Agency
December 18, 2007, the U.S. House of Representatives passed since 1975, the first energy bill, the bill calls for a reduction of oil imports, a substantial increase in ethanol and other bio-fuels to add the ratio. According to a recent U.S. federal Energy Information Administration said in May this year, ethanol production increased by nearly 8% to a record 2075.2 million barrels, while the source of bio-fuels such as ethanol that includes a number of food crops, including corn. The United States, this practice caused the dissatisfaction of many Third World countries because these countries have many people to eat food and die of starvation, the Americans had to do with the life-saving food to feed the fuel cars.
With the rising food prices, the production cost of ethanol and other bio-fuels has also risen, in order to reduce costs and moral responsibility, the Americans began looking for alternative crops to produce ethanol vehicle, watermelon is a good choice.
2007年12月18日，美国众议院通过了自1975年以来的首个能源法案，该法案要求减少石油进口，大幅增加乙醇等生物燃料的添加比例。而根据近日美国联邦能源信息局表示，今年五月份乙醇产量增长近8%，达到了创纪录的2075.2亿桶，而乙醇等生物燃料的来源就是包括玉米在内的众多粮食作物。美国的这种做法引起了众多第三世界国家的不满，因为在这些国家有很多人因为吃不上粮食而饿死，美国人却用救命的粮食来做燃料喂养汽车。
随着粮食价格的不断攀升，生产乙醇等生物燃料的成本也随之上涨，为了减少成本和道义上的责任，美国人开始寻找替代作物来制造车用乙醇，西瓜就是一个很好的选择。
根据美国德克萨斯州一家农业公司研究所的研究，在制造生物乙醇的同时需要大量的水，而西瓜不仅可以提供足够的乙醇原料，也能提供足够的水用来参与反应。通过对西瓜市场的调查发现，在美国每年有36万吨的西瓜因为卖不出去而腐烂在田地里，这些西瓜足够制造250万加仑的乙醇。
该研究所表示，从实验的结果看，西瓜是堪比玉米以及蜂蜜等高糖分作物的乙醇燃料来源之一，这意味着美国的那些西瓜种植商至少以后不用再担心西瓜卖不出去了。
不用再考虑剩油、甘蔗和菜籽油了——西瓜可成为生物燃料的一个最新来源。
科学家发现，西瓜中含有大量糖份，糖可直接用于提炼酒精，从而为汽车和农用机械提供动力。
西瓜味甘多汁、清爽解渴，是夏日生活里深受喜爱的水果。美国科学家却发现了它的一个全新作用，西瓜还可以制造乙醇燃料，这是一种可再生能源。
