Abstract

The article presents the research of bioelectricity generation by electro-biosystems with mosses in containers with a soil substrate and a graphite-Zn-steel system of electrodes on green roofs during the autumn-winter-spring period. It is revealed that the optimum conditions for the functioning of electro-biosystems is the temperature above +10°С with simultaneous regular humidification of the soil. In these conditions, an average current of 19.50 mA was recorded. Electro-biosystems react by lowering in the level of produced bioelectric potential and current strength at temperature drops below 10°C, and in particular at frosts, and also, in the long absence of atmospheric precipitation. Electro-biosystems with mosses to varying degrees survived the winter period: in a significant part of them, connections between the electrodes was damaged due to the effect of frozen water or/and freezing of plants. The most optimal configuration of the electrode system for generating bioelectricity, which functions at the initial level after winter time, is established. Thermo-insulated electro-biosystems with mosses under the conditions of regular humidification have prospects of their use on green roofs of buildings after general increase of the generated bioelectric potential and current strength.
