A low-cost technology introduced by the Electric Power Research Institute (EPRI) has substantially increased the output of an Australian combustion-turbine power plant. Using the EPRI technology, air passing through compressors at the Ecogen Jeeralong Power Station in Victoria is sprayed with a fine mist of demineralized water. This cools the inlet temperatures, increasing flow through the combustion turbine. In all, 2,500 fine nozzle sprays per unit are fitted to the turbine inlet air duct. The result: a 10% increase in power output during peak summer demand. Moreover, on hot, dry summer days, when industries and households switch on their air conditioners, the station can be brought to its peak load capacity of 465 MW within a half hour. In another installation in Missouri, the Utilicorp Energy Group estimates a similar system will save the utility more than $3 million through the year 2010. "With EPRI's aid, we identified ways of raising our plant capacity at a fraction of the cost of building a new plant or buying expensive power," notes Mike Jonagon, superintendent of gas turbines at Utilicorp.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
