This project investigates the extraction of electrical energy from trees. Using two electrodes, the electrical potential of different tree species and its dependence on reference parameters is determined. Our concept differs from the well-known lemon batteries that provide electricity from a lemon for a short time using electrodes made from different metals. Electricity from trees is inexhaustable as it arises from different ion concentrations of trees and earth. Our goal is to determine the relevant parameters for optimal electricity generation from trees. By doing so, we hope to make it substantially more efficient. Even if it is not possible to apply this form of electricity generation widely, the results of this study should enable trees to be used for supplying electricity to fire alarms and other small helpers in forests.
