Over the past 100 years, the global average temperature has increased by approximately 0.8 Celsius and is projected to continue to rise at a rapid rate. In this research we are aiming to stop or at least reduce this increase of heat. We were able to determine what type of surfaces can absorb the largest amount of IR radiation to prevent it from being absorbed by Carbon Dioxide, which is the main reason for global warming.
By placing different surfaces that vary in color and material, installing an infrared measuring tool pointing at the surface and calculating measurements it appeared that the substance of the surface does not affect the amount of reflected radiation. However, the color was very effective according to its gray scaling. The darker it is the less amount of reflection occurs. It turned out that using a black surface reduced about 72% of the radiation, while using a grey surface reduced about 35%.
It is known that darker colors produce more heat. Using several thermometers we were able to measure the surrounding area of the surface and prove that true. We are now studying a way to solve that problem by either converting that heat into another form of energy or using it as a heating mechanism.
