  1. A Problem of the Past Marlin B. Stovesand November 12, 2013 Section 6

  2. Introduction • Tomorrow’s Society • Pollution • Three Solutions: • Reverse Combustion • Splitting the Molecule • Carbonate Rock Bricks

  3. Reverse Combustion • Sandia National Laboratories in Albuquerque, New Mexico • Device that can chemically alter carbon dioxide • Hydrogen, methanol, gasoline

  4. Reverse Combustion Continued • parabolic solar concentrator • there’s a production of carbon monoxide

  5. Splitting the Molecule • UC San Diego chemists • This device, designed by Kubiak and Sathrum, utilizes a semiconductor and two thin layers of catalysts • First step • http://www.science20.com/news/turning_carbon_dioxide_into_fuel_using_solar_power

  6. Splitting the Molecule Continued • Second Step • Third Step • Semiconductors have bands of energy to which electrons are confined

  7. Carbonate Rock Bricks • Carbon in the Earth’s atmosphere reshapes and eventually overtime becomes a limestone substance • Limestone becomes cement upon reaction of calcium • Mineral carbonation technology replicates the Earth's carbon sink mechanism by combining CO2 with low grade minerals such as magnesium and calcium silicate rock to make inert carbonates • http://earthobservatory.nasa.gov/Features/CarbonCycle/page5.php
