Mode of action of Green Energy Tree Bowls (GETB): cylinder shaped bowl is placed on special ball-bearings on the entire bottom surface. The bowl's casing is slightly larger than the bowl itself. This allows the wind acting on the tree to slide it in various directions causing pressure on the GETB casing. On the inner wall of the GETB casing there are points which pressed against by the bowl, set in rotating motion cylindrical part located between the walls of the casing. The kinetic energy of a rotating cylindrical part is transformed then into electricity.
Linear systems (between lines and along the side of the road): the space between concrete elements is mostly filled with soil leaving space for GETB. Top layer of the soil is covered with vegetation resistant to drought.
Aeral systems are made with GETBs that are fixed on the metal frames. It allows separation of chambers with GETB from the soil and easy access to cables.
Materials: concrete panels imitating volcanic rocks.
