The call for papers is now open for the 5th International Energy Conversion Engineering Conference (IECEC), to be held 25-27 June 2007 at the Hilton St. Louis at the Ballpark, St. Louis, MO.

The IECEC provides a forum to present and discuss the engineering aspects of energy conversion technology, advanced energy and power systems, and devices for terrestrial energy systems and aerospace applications.

Papers on the technical aspects of energy conversion in the following topical areas are welcome and encouraged:

* Energy Policy, Environmental and Historical Perspectives
* Energy Conversion Device Technology
* Energy Storage Technology
* Thermal Management Technology
* Fuels, Combustion, and Terrestrial Energy Systems
* Aerospace Power Systems

Technical papers are sought that discuss the details of various types of energy conversion devices, including, but not limited to, the specific devices listed below. Papers should address specific characteristics, processes, and methodologies. Topics may include initial concepts, device component fabrication, modeling, analysis, testing, operation, and applications.

Among the topics being solicited:

o Direct Energy Conversion Devices and Components
+ AMTEC
+ Fuel Cells
+ Magnetohydrodynamics (MHD)
+ Photovoltaic Devices
