This research was a disappeared primary energy source for foreign decrease dependence on each country in the world for new and renewable energy policy trends. Each country policy is important in new renewable energy and for research and development; a lot of cost and investment, the long-term development plan for the acquisition of independent technology will be the biggest were aiming. Energy overseas reliance accounted for over 95% of that in case of The introduction of a reliable energies and Aggressive overseas energy often development presented the direction that the 2030, aiming at the level of 40%. Waste heat recovery patent analysis from 2001 to 2009 last 10 years, destination country, Korea, the United States, Japan, Europe on the register about patents. Classification technology by air conditioning system registers of patents concerning incidents, 474 (36.5%) the most high, the various main agents share look corporate (including foreign companies) 62.9% the most high, as personal share 28.2%,public institutions and universities share 8.9% were able to know that.

In mechanical industries, forging is one of the basic process. But comparing the other developed industries, forging industries can not reach at the level of that development. In forging industries, the quality of the products are totally depends on the skills of workers and also the precision of the equipments. Especially in case of open die forging, all processes are manual and the workforce are always exposed to danger. So keeping in view the aspect of danger during open die forging, a development of system has been made in this research, which is based on forklift. In the regard some additional device has been made especially. After than it is fitted with the forklift for safe and easy handling of jobs and products during open die forging process. First of all, development system mold has been assembled to the system, after than it is assembled with forklift. This development system has been applied for handling of large scale products over 300Kg, and the satisfactory result with uniform quality of the products have been achieved due to this mechanical setup.
