Smart Vertical Axis Highway Wind Turbine

International Journal of Engineering and Advanced Technology Studies, 2022
Energy is an important aspect of our everyday life. The resources we use are limited whereas the population consuming the same is increasing day by day. Nowadays the requirement for electricity is much higher than its generation; hence the main objective of our work is to produce electricity at low cost with no effect on the environment.

Vertical axis wind turbine

2015 International Conference on Technologies for Sustainable Development (ICTSD), 2015
Increasing demand for energy in recent years has seen a rise in development of alternative energy sources. Wind being one of the most abundant and easily available sources is an excellent alternative to conventional energy sources. Vertical Axis Wind Turbines (VAWT's) are of two type's viz. Darrieus (lift based) and Savonius (drag based).

Harmony Vertical Axis Wind Turbine

SSRN Electronic Journal, 2019
In this paper we present our innovative wind turbine structure for enhancing efficiency for various applications. The smart wind turbine consists of curvy savonius blades which are connected to the shaft. The blades are designed in a such a way that, if wind strikes on any one part of blade (i.e.
