Biomimetic Energy Harvesting: Wind-Induced Tree Movement for Electricity Generation

Wind energy is a sustainable renewable energy source. However, harnessing wind energy traditionally involves installing large scale wind turbines that require large amounts of land and pose environmental concerns such as bird and bat killing, deforestation, and microclimate disruption. This study explores an innovative and nature-based approach to utilize wind-induced tree branch movement with non-destructive linear generators for power generation. By using a linear generation system, tree branch movement can be converted into electrical power through mechanical devices tied onto branches. Initial testing showed the feasibility of this technology, but many factors including tree height, branch length, branch diameter, wood properties, and canopy density can impact energy output. Computational modeling can be used to predict optimal placement of tethering and optimize parameters such as rope tension, tree species selection, and generator configuration to enhance efficiency and minimize mechanical stress in these varying conditions. Simulations are developed to evaluate the system's scalability and possible energy output. We will present modeling results to assess the feasibility of this natural tree-based power generational system as a sustainable alternative to traditional wind turbines and solar panels. Experiments with linear generators will also be presented to validate and improve energy yield for enhanced system performance.
