Smart radiators are powerless to adapt

Article Abstract:

A post-doctoral student at the Department of Engineering Science in The University of Oxford has developed a four-layer coated structure that enables the surface of space satellites to radiate energy when hot and retains energy when cold. The system is designed to work with infrared wave lengths in a space environment but it could also be used in other land based systems with slight modifications in materials.

Defence technology shows good vision

Article Abstract:

A report on the latest low cost technologies developed by the Qinteiq company shows a future vision for remote earth observations, global communications and advanced materials. One of the goals developed by NASA, Qinetiq and other organisations is to come up with an economic system of locally boosting mobile band widt h, particularly for major sporting events.
