In recent years, the Non-Renewable energy sources are dwindling day by day, so we are in such a position to produce energy by using renewable energy by utilizing renewable energy sources. The conventional blade wind turbines are used to produce energy but its cost is very high and it has many disadvantages such as capital cost, running cost, friction loss and it is also dangerous to birds and is noisy as well. Hence, there is a need to produce a low-priced and safe replacement for conventional windmills. The concept of bladeless windmill works on the principle of vortex shedding effect. Vortex bladeless windmills are a wind powered generator that generates electricity with minimum moving parts. It generates the electric current by using the oscillation or vibrations produced due to the wind. It works on the principle of Vortex induced vibrations (VIV). Hence, the electricity is generated by using linear alternator or piezoelectric material. Usually, structures are designed to minimize vortex induced vibrations in order to minimize mechanical failures. But here, we try to increase and capture the vortex induced vibrations (VIV) with maximum deflection of bladeless windmills which is used to produce electricity with experimental and geometrical approach. Utilizing piezoelectric technology as a clean energy which conserves the environment and reduces greenhouse gas emissions produced from the fossil fuel combustion. This low cost power production assists in reducing electricity bills for the retail consumers. Piezoelectric power production has been applied in limited projects and it has a greater potential growth in the modern world.
