1. Introduction
Energy is the crucial factor to the development in most industrial area and we have to supply it from various resources using technical methods. As we have entered in the 21th century, it becomes one of the most important missions to replace original energy with new energy to last current development long. Economically, because the original energy resources like coal, petroleu
