With an aim of being up to 50 % lighter than conventional chemical battery packs used by the British infantry, a new solar and thermoelectric-powered system could make a significant contribution to future military operations. The project is being developed by the University of Glasgow with Loughborough, Strathclyde, Leeds, Reading and Brunel Universities, with funding from the EPSRC (Engineering and Physical Sciences Research Council). It is also supported by the Dstl (Defence Science and Technology Laboratory). The system combines solar PV cells (photovoltaic), thermoelectric devices and cutting-edge energy storage technology to provide a reliable power supply like a normal battery pack. The thermoelectric devices and solar cells can be woven into soldiers' battle dress. As it is much lighter, the system is designed to improve soldiers' mobility. Moreover, by eliminating the need to return to base regulary to recharge batteries, it will increase the potential range and duration of infantry operations. It will also absorb energy across the electromagnetic spectrum, making infantry less liable to detection by night-vision equipment that uses infrared technology. During the day, the solar cells will produce electricity to power equipment. During the night, the thermoelectric devices will take over and perform the same function. The system will also incorporate advanced energy storage devices to ensure electricity is available on a continuous basis. A key aim of the project is to produce robust, hard-wearing designs specifically for military use in tough, hostile conditions. A prototype system will be produced within two years.
