7. Conditions for Survival 7.1 Radiation shielding and temperature regulation For shielding the inhabitants of Cygnus from the harmful solar radiation‚ many metals are used. First of all polished silver is used that has an emissivity of only 2%‚ meaning that 98% of the incoming radiation is blocked by it. There are 10 layers of polished silver‚ with other materials in between. Therefore the10 layers of polished silver let less than 0.0001% of solar radiation to reach the interior of the settlement

Ocean Thermal Energy Conversion SPH3U I. Introductory Covering over 70% of the earth ’s surface‚ water is one of the most amazing energy sources. From olden times‚ people had previously utilized the force of the waters in order to crush grain or help them to do their work more efficiently. Since then as a power source‚ water draws a lot of attention due to the efficient manner in which it gets to produce electricity. Ocean Thermal Energy Conversion (OTEC) is a method introduced in

recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal‚ which is far less expensive and energy intensive than creating new aluminium through the electrolysis of aluminium HYPERLINK "http://en.wikipedia.org/wiki/Aluminium_oxide" oxide (Al2O3)‚ which must first be mined from bauxite ore and then refined using the Bayer process. Recycling scrap aluminium requires only 5% of the energy used to make new

Marie Curie was a famous Polish chemist. Marie and her husband Pierre Curie were early researchers in radioactivity. She received her first Nobel Prize in 1903 for physics‚ together with Pierre and Henri Bequerell‚ for research in the area of radioactivity. In 1911‚ she was given a second Nobel Prize in Chemistry for her work in discovering radium and polonium. Discovery of Radium and Polonium Marie Curie received the Nobel Prize in Chemistry in 1911 for her discovery of radium and polonium. She
