Processing batteries from boiled potatoes

We are so familiar with the appearance of batteries, in all kinds of devices with a common structure consisting of two electrodes of zinc and copper, but perhaps few people have heard of 'potato' batteries.

Professor Haim D. Rabinowitch, Hebrew University and Professor Boris Rubinsky, University of California have turned this idea into reality. So far, two people have conducted electrolysis studies to solve many life problems, applied to many devices. In particular, including electrical equipment used in health, capable of producing electricity.

In a recent announcement, two scientists have found a new way to create an effective battery from potatoes, replacing conventional batteries. They found that, just by boiling the potatoes before using them in the electrolysis process, the electricity generated was 10 times higher than the raw potatoes, allowing "batteries" to work for several days, even some week.

The battery made from potatoes provides enough electricity to light all kinds of LEDs.

The scientific basis of this finding is related to the reduction in salt resistance in the potato, almost the same way that engineers optimize the use of conventional batteries. The ability to produce and use low-power batteries of potato batteries is reflected in the lighting of LEDs.

In terms of cost analysis, battery chips produce 5-50 times less energy than conventional batteries today. Clean lamps using this 'green' battery are six times more economical than kerosene lamps in developing countries.

According to Professor Haim, ingredients such as cooked potatoes or other types of vegetables can provide an 'immediate, environmentally friendly and low-cost' solution, for the demand for power. Low voltages in areas without access to electricity infrastructure in the world.

The selection of potatoes is also highly practical, as it is grown in more than 130 countries, in many climates. Potato production is also quite large. According to the figures of the World Food and Agriculture Organization, in 2007, worldwide production reached 325 million tons. Potato consumption expanded strongly in developing countries, so using potatoes as a battery is a good solution.
