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 global … » 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 at… » 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
