Carbon Capture

Calera cement, funded by Vinod Khosla, which would take CO2 from the air to make cement and contour crafting which is a technology for printing buildings to speed up construction by 100 timees.

Vinod Khosla is pouring his own millions into science experiments to counter global warming — and to prove he’s the smartest guy in the Valley.

Making cement without also making carbon dioxide seems impossible; the basic chemistry of the process releases the gas. But maybe that’s not really true, Stanford University scientist Brent Contstantz began thinking last year.
