Drawbacks of thermal batteries, however, include occasional unreliability, have high cost, low energy density, and associated environmental hazards over their entire life cycle - from production, to use, to disposal. For these reasons, a replacement system is needed for thermal batteries that eliminates these drawbacks. Aerodyne Research, Inc (ARI) proposes a specialized version of its miniature engine/generator technology for the Thermal Battery Replacement (TBR) application. This version is based on a previously developed a design for a fully sealed battery-like power source based on the miniature engine/generator for the downhole power environment for oil exploration and drilling applications. This design could handle shock loads as high as 1000 g's, pressures up to 20,000 psi, and temperatures in excess of 170øC, all of which exceed the requirements for the thermal battery replacement. In the Phase I program, ARI will demonstrate the functionality of its TBR system. The Phase I program will also develop a preliminary design of a Phase II TBR system. Benefits: The TBR system will greatly reduce or eliminate the environmental hazards associated with current thermal batteries while also reducing the cost of these components. The TBR system can also replace thermal batteries in a wide range of other military and commercial applications since the TBR system is easily scaled for longer durations and different power levels.
