Suitable Electrodes and Conditions for Optimum Production of Electricity from Food and Fruit Samples

Electricity from different food and fruit samples and their ability to power LED bulb or charge smaller devices have been studied. Combination of electrodes capable of producing reasonable voltage across food and fruits has also been determined. It is found that for potato, tomato and lime; copper and zinc are best electrode combination that can produce high voltages and currents while zinc and lead were found to be the best for lemon. With separate series connections of the six different food and fruit samples, voltages greater than 4.00 V are obtainable. There is an exponential growth in current when potatoes are heated. Tomatoes were found to be more stable in generating current than the others. The voltages produced from series connection of each of samples types can light and charge phones for rural homes.
