An interesting GHG emissions analysis on the current Netflix model of acquiring a movie versus driving to your local movie rental yourself. There are so many different analyses like these that should all be tracked somewhere.
640 tons of CO2 emissions versus 354,000,000?
If accurate, or even slightly accurate, that's a huge difference.
What is more eco-friendly that that? My hunch: Movie downloads services, maybe the "newly legit" BitTorrent service, or stuff like HBO on demand.

At least one company claims they've found a way to convert greenhouse gas (GHG) into useful materials within a "bioreactor". How? Simple: Make genetically engineered E. coli bacteria which will then produce an enzyme (carbon anhydrase) that will convert carbon dioxide (CO2) into bicarbonate. Otherwise known as baking soda. Or limestone.
I stumbled upon the article in Technology Review titled "Capturing Carbon with Enzymes, A New Process Turns Greenhouse Gas Into Useful Materials" tonight while doing my standard before-shuteye hunt for blogworthy green nerd news. (Thanks for sharing this, JiltedCitizen on Hugg.)

A new way to capture carbon dioxide from smokestacks produces a raw
material that can be sequestered underground or turned into substances
such as baking soda, chalk, or limestone. CO2 Solution, of
Quebec City, Canada, has already tested its process on a small
municipal incinerator and an Alcoa aluminum smelter. Its scientists are
now working with power-plant equipment giant Babcock and Wilcox on ways
to adapt the technology to a coal-fired generating station.

....Dr. Scott Matthews, a shipping expert at Carnegie Mellon
University, calculates that the US shipping fleet alone creates more
CO2 than the entire country of Canada.
Thanks, Sustainablog.
