Three Solutions: Reverse CombustionSplitting the MoleculeCarbonate Rock Bricks

Reverse CombustionSandia National Laboratories in Albuquerque, New Mexico

Device that can chemically alter carbon dioxide

Hydrogen, methanol, gasoline

Reverse Combustion Continuedparabolic solar concentrator

theres a production of carbon monoxide

Splitting the MoleculeUC San Diego chemists

This device, designed by Kubiak and Sathrum, utilizes a semiconductor and two thin layers of catalysts

First step

Third Step

Semiconductors have bands of energy to which electrons are confined

Carbonate Rock BricksCarbon in the Earths atmosphere reshapes and eventually overtime becomes a limestone substanceLimestone 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 rockto make inert carbonateshttp://earthobservatory.nasa.gov/Features/CarbonCycle/page5.php
