Potato battery basic composition and performance. Potato Zn/Cu galvanic cell battery basic structure. The battery (Kcell = 15.5 cm) was used to light two white LEDs.

The bioelectrolytic low power electrical energy source introduced in this study brings an extra dimension to the utilization of the globally fourth most abundant crop, accessible essentially all over the world, made of solid components, and requires low initial financial investment compared with solar or conventional batteries. Boiling and the simple assembly do not require special skills; it is both easy to operate and environment friendly. Last but not least, the power generated by Zn/Cu-potato is much cheaper than any conventional portable battery and produces with LED’s substantially cheaper lighting than kerosene. The proposed technology may be immediately implemented in the developing countries for improving the life quality on numerous people who do not have access to grid electricity.
