Wind Energy Harvesting From Flapping Leaf Generator

Abstract

The increasing concerns towards depletion of non-renewable sources and development of innovative cost efficient technologies for the use of renewable energy sources are the driving factors for using wind energy for power generation. Wind energy is traditionally harvested by using wind turbines for generating power. The cost of typical 1kw wind turbine starts at 30k; moreover they produce noise and are huge in size, thus the initial cost for setting up a plant increases. This paper is on harvesting the wind energy using Piezo electric stalk attached with flapping polymer leaf. The flapping of the polymer leaf due to the wind produces pressure on the Piezo electric stalk, this vibration yields electrical energy. In order to meet the energy demand 1000?s of leaves are parallelized thus result in Piezo tree. This Piezo electric stalk is made up of Polyvinylidene Fluoride (PVDF). The cost of setting up this prototype is very cheap compared to the traditional wind turbines. This paper details on the vertical stalk- horizontal leaf and horizontal leaf ?horizontal stalk arrangement, Piezo tree, and the ways of harvesting the energy generated and the places it can be erected.
