Abstract

Green energy likely wind energy, solar energy, biomass energy, and tidal energy, with the characteristics of being free, natural, and free from pollution problems, and renewable. In this research, we used air conditioner with split (AC Split) model has a large energy potential that could be utilized, from exhaust air velocity in the outdoor unit which reaches 2-6 m/s. A simple prototype is designed using a wind turbine and generator as the main components in energy production. The design of a wind turbine prototype with a Savonius vertical axis wind turbines (VAWT) has several advantages such as low wind speed to drive the rotor. We used method consists of five stages. Firstly, is literature study; secondly design and modelling using computational fluid dynamics software; thirdly is manufacturing and assembly; next stages is measurement and data collection; and the last stages is testing, which is evaluating the performance of wind turbine as possible modifying tools if needed. This simple prototype has been evaluated with two models of Curvature angles, is the blade with single angle of curvature of 46.5o within four-blade model that is curved, and blades with double curvature angles of 45o and 30o of the curved three-blade model. The results of test used a reducer with there-blades as staring test, we found the rotation speed was dramatically increased from 20 to 90% was reaches less than 60 seconds. Also the net power extracted by double of curvature angle is maximum reaches from 13% to 36% of turbine power (Watt), it should not be addressed for the power extraction capability of single curvature angle model. We suggested with this result could as a simple prototype in the future. It’s slightly possible to be applied as an alternative solution in green energy industries.
