CORRELATIONS BETWEEN ELECTRICAL PERFORMANCES OF POTATO BATTERIES TREATED UNDER THREE DIFFERENT CONDITIONS.

ABSTRACT

Using basic galvanic cell principles, the ability of tissues to generate electrical current through electrolysis was characterized. Studying Zn/Cu electrolysis in animal organs revealed a fundamental and measurable tissue-specific property – the galvanic apparent internal impedance (GAII), that is most likely related to the salt bridge function of tissues delineated by electrodes.

We now report on new fundamental studies on GAII in vegetative matter and on a simple way for significant performance improvement of Zn/Cu-vegetative battery.

We show that boiled potato tissues with disrupted cell membranes generate electric power up to ten fold higher than equal galvanic cell made of untreated potato. The study brought about basic engineering data that make possible a systematic design of a Zn/Cu-potato electrolytic battery. The ability to produce and utilize low power electricity was demonstrated by the construction of a light-emitting diode based system powered by potato cells.
