Climb Higher Than Mt. Everest, Without Leaving Manhattan

Who knew such extraordinary altitudes could be found, hidden inside the towers of Manhattan's Flatiron District? But, behind the nondescript door of a 5th-floor office on 21st Street, heights as great as the Himalayas are waiting to be scaled. Gizmodo took a deep breath and visited the atmospheric wizardry of Hypoxico » 2/13/14 5:00pm 2/13/14 5:00pm

CO2 Scrubber Sucks Up Emissions From Cars, Home Heating

University of Calgary scientists are working on a machine that would pull carbon dioxide from the air in an attempt to scrub out emissions from diffuse sources, such as car exhaust and home heating. These ���diffuse emissions��� account for roughly half of the CO2 that goes up into the sky every day, contributing to… » 10/02/08 12:30am 10/02/08 12:30am

"Clean Coal" No Longer Oxymoron at New Power Plant

Maybe you've heard the plans for "clean coal" (aka carbon capture and storage), a technology that collects carbon-dioxide exhaust from formerly high-polluting power plants, condensing and freezing it for storage in depleted natural-gas fields. This month, energy provider Vattenfall fired up the CO2 collection process… » 9/21/08 4:30pm 9/21/08 4:30pm

Scientists Propose Adding Lime to Oceans to Reduce CO2

The oceans already absorb megatons of atmospheric carbon, but scientists say that there's a way to boost this so that CO2 levels could drop to pre-industrial age levels. The answer sounds like a cocktail recipe: add lime. Limed seawater has boosted alkalinity, which lets it absorb more CO2 and stops it from releasing… » 7/21/08 12:20pm 7/21/08 12:20pm
