  • An interesting article on using algae to treat wastewater and produce outputs of clean water and biofuel.

  • Michael Jackson the environmentalist? I have to hand it to him for his 1996 "Earth Song," but I am more bothered/perplexed by the NON-release of the song in the US. I guess it's not part of Earth? Feel free to make snarky comments...

  • A good article outlining the danger's of private public water management in Coachabamba. Locals want COMMUNITY management, and they should get it, since they have built their water systems from scratch and managed them to serve their community's needs. The central government bureaucrats have other ideas, unfortunately.

  • SciDevNet has a special supplement on reducing emissions from deforestation and forest degradation (REDD). Lots of info!

  • Nation-by-nation carbon footprints, and one way to reduce them -- meat-free Mondays!

  • Stimulus money and the water market: "GE estimates the global market, with subsectors including water technology and infrastructure, pollution control, water management and treatment, to be worth around $400 billion. New, cost-effective technologies are also emerging to facilitate remotely metering water use, treating waste water for reuse and desalinating sea water, the panel said."

  • No free lunches! "According to Jim Glanz in Wednesday’s New York Times, an earthquake shook Basel, Switzerland on December 8, 2006, damaging buildings and terrifying the residents. It had been 650 years since an earthquake toppled the towers of the Basil cathedral. This time at least it was not the hand of God. In an effort to produce almost limitless clean energy, a hole had been drilled 3 miles deep, fracturing the bedrock that separates Earth's crust from its molten interior. Water was heated by passing it through the fractured rocks. The project shut down immediately, but many smaller quakes continue to rattle the residents. A similar project to harness geothermal energy is underway in Sonoma County, CA." Read more on that here.

Algae

Accepted estimates, with achievable efficiency improvements --

There's enough oil from Algae in 15,000 square miles of USA real estate to provide for All of our annual fossil fuel needs.

If all of this land were in one rectangular piece, it would be 120 miles by 125 miles (about 1/7th of the area of Colorado, or less than 1/7th the area of corn harvested in the United States in the year 2000).

The water for such an undertaking has been offered ... the land in the desert SW is readily available.

Note: The chemistry & physics is semi-complicated because of the high fuel viscosity ... Can bore you with the details if you request.

Dilution, micro-emulsification, pyrolysis and transesterification are the four techniques.

One a large-scale societal level, consuming just a bit less meat has dramatic effects on carbon output, water use and quality, as well as health.

Meatless Mondays encapsulate this activity, and you can view the resources provided by the American organization working on this:
