There are many kinds of renewable energy and not all suitable enough to generate electricity. Some kind of renewable energy that nowday has big atenttion is wind power. To generate electricity from wind we need wind turbine and there are two kinds of wind turbine, which are HAWT (Horizontal Axis Wind Turbine) and VAWT (Vertical Axis Wind Turbine). HAWT has enter marketplace and many country on sub-tropical area has install this technology to produce electricity with clean and environment-safe method. That because HAWT promise the high efficiency and have big installing capacity (~ Megawatt electric). Continue Reading »

Many kinds of energy sources which available in the nature but not all could be easy used by human being. We have to convert itself become one kind of energy which easy transport/distribute and used for widely applications. By research, we choose electric power as media for store energy and until nowdays electric power still become the mainly media for storing energy. Because the capability on storing energy and not available naturally, we can said the electric power as energy carier. We have to produce electric power by converting energy sources which available naturally, like using steam turbine, photovoltaic, wind turbine, etc. Continue Reading »

All of we know that world energy demand always continue increase and most of world energy needed are obtained by utilizising the fossil fuel. It OK, but we have to realize that the fossil resources is non-renewable energy so in the future it will spend off. Not just than reason, there bad impact to environmental because burning fossil fuel.
Carbon dioxide that release from burning fossil fuel for heat generation will make green house effect. Ok, green house effect for some limited range is very important for earth, that is to take earth temperature balance between noon and night. But when the concentration of carbon dioxide at the atmosphere increasing rapidly, its danger! Continue Reading »

The worldwide demand for hydrogen (H2) is ~50 million tons per year and growing rapidly. Hydrogen is used primarily for production of ammonia for fertilizer and conversion of heavy crude oils into cleaner liquid fuels. The international cooperation has effort to deliver H2 as a replacement fuel for transport vehicles. The future, we would like use hydrogen as fuel for transport vehicles than gasoline/diesel oil/natural gas as fuel. Continue Reading »
