Furthermore, each cup containing soil mixed with star fruit juice was associated with a series of copper wire and zinc plate, the electric current to flow. The result, the energy created by the voltage listrikpun fairly, ie up to 5 volts, enough to turn on the lights. The resulting voltage is also greater than the voltage of the battery stone fruit.According to him, electrical energy is created by starfruit has a high acidity level to be able to conduct ions and electrons are there on a piece of copper and zinc. Thus create an electric current. On average, 10 points starfruit is capable of creating an electric voltage up to 2.5 volts, equivalent to one dried fruit batteries. Even in his experience, the electrical energy of the star fruit vegetables can last up to one month old.Sunarto electronics teacher who also at one high school in this Magetan Bendo, hopes his invention will be further developed for a variety of household needs. Of them to turn on the radio, wall clock, until the lamp lighting for rural areas that have not been touched by electricity.
Until now, Sunarto still continue to develop its findings. He wanted later after developing alternative electric energy this invention can be packaged in a practical form of energy products like batteries. Thus, the findings could be developed as one of the alternative energy electricity rates amid increasingly heavy impact for small people
