13. Conclusion The extensive use of MHD can help in saving billions of dollars towards fuel prospects of much better fuel utilization. The potential of lower capital costs with increased utilization of invested capital provides also a very important economic incentive. The beneficial environmental aspects of MHD are probably of equal or even greater significance. It simultaneously assures better utilization for our natural resources. It can therefore be claimed that the development of MHD for electric utility power generation is an objective of national significance. Bhubaneswar Engineering college 13 MHD Generator
