Break out the big fruit for a “green” source of energy. According to a new study, watermelon juice could be used to make the biofuel ethanol.
Almost 20 percent of watermelons grown in the U.S. are rejected because of scars or unusual shapes. Instead of being thrown away, these reject watermelons could be pressed into service in making the “green” fuel. Researchers even envision mobile breweries that would drive to watermelon farms and transform the juice on the spot.
