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."
