Here's another one, from Columbia, only they've formed a company and are talking about developing the full blown version by 2011. -------------------------------------------------------------------
The carbon capture technology was developed by GRT and Klaus S. Lackner, a professor at Columbia University’s Earth Institute and the School of Engineering and Applied Sciences. The Tucson-based technology company began development of the device in 2004 and has recently successfully demonstrated its efficacy. The air extraction device, in which sorbents capture carbon dioxide molecules from free- flowing air and release those molecules as a pure stream of carbon dioxide for sequestration, has met a wide range of performance standards in the GRT research facility. "This is an exciting step toward making carbon capture and sequestration a viable technology," said Lackner. "I have long believed science and industry have the technological capability to design systems that will capture greenhouse gases and allow us to transition to energies of the future over the long term." The GRT’s demonstration could have far-reaching consequences for the battle to reduce greenhouse gas levels. Unlike other techniques, such as carbon capture and storage from power plants, air extraction would allow reductions to take place irrespective of where carbon emissions occur, enabling active management of global atmospheric carbon dioxide levels. The technology shows, for the first time, that carbon dioxide emissions from vehicles on the streets of Bangkok could be removed from the atmosphere by devices located in Iceland. This could present a solution to three problems that until now have posed intractable obstacles for advocates of greenhouse gas reduction: how to deal with the millions of vehicles that together represent over 20 percent of global CO2 emissions, how to manage the emissions from existing infrastructure, and how to connect the sources of carbon to the sites of carbon disposal. "This significant achievement holds incredible promise in the fight against climate change," said Jeffrey D. Sachs, director of The Earth Institute, "and thanks to the ingenuity of GRT and Klaus Lackner, the world may, sooner rather than later, have an important tool in this fight." http://www.physorg.com/news96732819.html http://www.grestech.com/press.php --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups Global Change ("globalchange") newsgroup.
