Engineers at USC have developed a new technique for '3-D printing' houses.

"Called Contour Crafting, the system spits out layers of concrete to build a structure from the bottom up. Caterpillar is sponsoring Khoshnevis's research. From the Contour Crafting page:

Contour Crafting technology has great potential for automating the construction of whole structures as well as sub-components. Using this process, a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run, embedded in each house all the conduits for electrical, plumbing and air-conditioning. The potential applications of this technology are far reaching including but not limited to applications in emergency, low-income, and commercial housing."

Carbon-Negative Cement

Submitted by Charles Siegel on Thu, 09/04/2008 - 13:42.

Particularly interesting since a Stanford professor has just invented a new method of manufacturing cement that actually sequesters CO2. Now, cement manufacturing accounts for 5% of the world's CO2 emissions. With this technique, cement manufacturing would subtract 2.5% from the world's CO2 emissions.
