Theresa Harmanen’s Alma Tree Lamp is an innovative lighting design concept that takes energy directly from nature without destroying it. Designed to be plugged directly into a tree, this project explores the energy created when a tree “communicates” with its soil. By harvesting and storing this energy, Alma forgoes the need for a grid power source, lighting up the streets while highlighting the beauty of plant life.

Trees produce energy in the process of maintaining a PH balance between itself and the soil, and the Alma concept uses this energy through a tree metabolic energy harvesting technology. Storing the energy is done by using long-lived thin-film batteries containing non-hazardous materials, and the harvested energy can be used to power LED lightsactivated by motion sensors. The individual units can be placed according to the size of the tree.
