Solar-Powered Soldier The superimposed numbers are readings for anticipated sunlight. Engineering and Physical Research Sciences Center ‘Solar Soldier’ Project Creating Power-Harvesting Uniforms for British Infantry -- Popular Science
Future camouflage uniforms will draw power from the sun during the day and from a soldier’s body during the night, turning infantrymen into true sunshine patriots. The system could provide continuous power for a radio, GPS and weapons, but at half the weight of traditional battery packs.
The Engineering and Physical Research Sciences Center in the UK is working on a new type of fabric that uses solar photovoltaic cells, thermoelectric devices and advanced lightweight batteries. Because the system absorbs heat, it could even serve as a type of wearable stealth cloak, making a soldier less susceptible to detection with infrared cameras.

My Comment: I never thought that the science behind military uniforms would be as complicated as it is today.
