So we had used table fan. When table fan placed in front of wind turbine as an artificial source which causes the wind turbine to rotate, based on this we can obtain results. And the result is obtained with respect to time. 4. EXPERIMENTAL RESULT AND DISCUSSION The work piece selected for experimental work was a 40mm square mild steel piece with 6mm thickness. Figure-9a shows the work piece before surface finishing and figure-9b shows that after surface finishing. Figure-9a Figure-9b The experimental results for different thicknesses of material removal and time requirements are given in the table-1. The probable time for indirect utilisation using Dynamo- battery- motor method is also given for comparison. Jayaram. A .S. :: Direct Utilization of Wind Energy 4603

No. Thickness of material Approximate time taken(in minutes) removed (in mm) For direct utilisation For Dynamo- battery motor method 1 0.05 8 16 2 0.10 15 30 3 0.15 22 44 4 0.20 30 60 The above results are plotted as shown in figure-9. It also shows the comparison between direct method and indirect method. 70 60 For direct utilisation For Dynamo- battery –motor method Time required in minutes 50 40 30 20 10 0 0.05 0.1 0.15 0.2 Thickness of material removal in mm Figure-9: Time required for different material removable thicknesses The graph shows that time required is directly proportional to the thickness of the material removed. With direct method of utilisation, the time taken is one half of that of indirect method of Dynamo-battery-motor method because the overall efficiency of the system is the product of dynamo efficiency (0.8), battery efficiency(0.8) and motor efficiency(0.8). That is 08.X0.8X0.8=0.51 5. CONCLUSION It is concluded that the wind energy can be directly utilized to do surface finishing or any such mechanical operations like turning, milling and so on. Also, with little automation, we can make the raw materials to move automatically one after the other in to the equipment and finished products can be collected at the outlet of the machine. Direct utilisation is more efficient and less costly compared to indirect method of utilisation. Jayaram. A .S. :: Direct Utilization of Wind Energy 4604
