Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues have co-authored a paper (doi:
10.1021/ja2100005) in the
Journal of the American Chemical Society describing a novel, cheap material that scrubs CO2 from ambient air, even at the very low concentrations of the atmosphere. The material is easily manufactured, and carbon captured is readily removed from the polymer, allowing recycling of the polymer and sequestration of the carbon. The researchers, co-authors of
Beyond Oil and Gas: The Methanol Economy regard this as more than simply a technique for decreasing the carbon emissions of industrial processes and fossil-fuel burning machines, but as possibly an energy-carrier, by using the "catalytic hydrogenation of CO2 with H2 where the hydrogen has been obtained from water electrolysis (

Will algae defeat global warming? "Fed a generous helping of CO2-laden emissions, courtesy of the power plant's exhaust stack, the algae grow quickly... The cleansed exhaust bubbles skyward, but with 40 percent less CO2... The algae is harvested daily and a combustible vegetable oil is squeezed out: biodiesel".

Cool! Toronto's Deep Lake Water Cooling System was launched today. The system cuts electricity consumption in commercial buildings by 75 per cent by drawing near-freezing water through pipes extending five kilometres out into Lake Ontario. According to the
city, the system will save enough power to service more than 100 Toronto office towers or 4,200 homes per year, and it will eliminate 40,000 tonnes of carbon dioxide.
Here's a public television segment explaining the process. Seems like it makes a nice complement to the lakeshore
windmill.
