BEIJING, March 24(Xinhuanet) -- Everything gives off heat, but you can hardly feel it, let along "watching" it.
Through thermal imaging, or infrared thermography, seeing different scenes of our surroundings becomes possible.
Following photos show the amount of heat given off by everyday household objects. They can show where appliances may be overheating or using too much energy, and help us to lead a green life.
