We are actually the second planet-altering species. Three billion years ago, Cyanobacteria were the first. They totally changed this planet to one that is safe for oxygen breathers. That was a big change for species at the time, and most species didn’t make it. Nearly all of them went extinct.

If we’re lucky, we won’t change our environment as much as Cyanobacteria did.  That’s the goal of the US Department of Energy ARPA-E. Inspired by the success of the Defense Advanced Research Projects Agency; ARPA-E will fund high-risk, high-reward advances with the potential to completely change the way our species generates and consumes energy.

Arizona State’s Wim Vermass was of the 37 recipients of the DOE ARPA-E funding. He is teaching the ancient species to make our future fuel and to custom-make it just the way our species wants it.

Here’s a low carbon cooling technology that uses hot water from waste to make A/C without fossil fuels, saving 80% over fossil-fueled chillers.

This industrial scale chiller from the Chinese company Broad Central Air can convert many different kinds of waste heat into air conditioning. The waste heat can come from many industrial sources, including what the Chinese site calls “town gas”  - methane from town landfill, collected and burned to generate heat.

There has been a lot of discussion over the last few years about biofuels and whether or not they are actually green, especially when produced on a large, global level.

A new study led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo says no, they aren’t green (when it comes to climate change). However, there are still many important factors to keep in mind before claiming this is the end of a long and complicated discussion.

That is correct — not million but billion, not in one year but in one month! That is how much the US spent on imported oil in September 2009.

For those concerned about the US economy or national security risks, T. Boone Pickens and data from the US Department of Energy’s Energy Information Administration (EIA) show us that foreign oil imports should be at the top of our list. We rely very heavily on foreign oil and send a good chunk of our money to other countries to supply us with that oil — $25 billion last month alone!

Take a closer look.

A team of researchers at MIT are engineering a strain of bacteria, which is similar to the type that causes tuberculosis, to produce biofuel.

The researchers say that the bacteria are useful because they are hungry for a number of sugars and toxic compounds and produce lipids that can be converted to biodiesel.

Here’s a resource we’ll have plenty of as ever wider swathes of our forests get decimated by pests like the Pine Bark Beetle. Dead trees. In an adaptation eerily reminiscent of Thomas Edison’s dictum We live like squatters, not as if we owned the property” a university has invented a technology to harvest one of the horrific effects of climate change.

The University of Georgia Research Foundation has developed an innovative way to turn dead trees into a liquid fuel and has licensed it to Tolero Energy in California. We could be driving on our dead forests as soon as 2010.

The technology represents a leap forward for the biofuels industry. Not only does the resulting biofuel need no additional refinement before blending with diesel fuel, but it is a naturally very low-sulphur biofuel.

And it would prevent additional CO2 from being released if the forest was left to decay.

But the biggest leap is in thinking of using a non-food source (at least for us humans) of biomass that we will have an ever increasing abundance of, as our climate gets worse and worse. And it doesn’t take scarce water resources to grow. Quite the contrary. Droughts and rising temperatures are all it needs.

Dead trees are one of the major sources of waste biomass, says Tolero CEO Chris Churchill.

The U.S. EPA has found that a simple, inexpensive rooftop solar panel can provide enough power to run a fan and remove toxic fumes from homes sitting on contaminated ground.  The EPA gave solar-powered venting a test run on several homes earlier this year, in a Superfund action aimed at tricholoroethene (TCE) vapors in a Grand Prairie, Texas neighborhood.  The pollution had been traced to a site occupied by the now-bankrupt Delfasco Forge company.

Compared to conventional remediation that involves weeks, months or even years of work along with a potentially huge carbon footprint for transporting or capping soil, the solar-powered exhaust systems took mere hours to install and resulted in an immediate 95% reduction in TCE vapors within the homes.  The EPA plans to extend the program this fall to other homes affected by the Delfasco site.

The modern U.S. Navy may be about to put a 3,000-year-old weedlike biofuel crop in its tank.  Camelina, the “new darling” of next-generation biofuels, is among a small group of biofuels under consideration for testing  this year by the U.S. Navy.  One of the aircraft to be tested is the F/A-18 Super Hornet strike fighter, the latest incarnation of the battle-proven Hornet.  Sustainable Oils of Montana has just won a contract to provide 40,000 gallons of camelina-based jet fuel to the Navy, so the chances look good for putting the ancient crop to a new use.

The Naval Air Systems Command fuels team will start with a lab analysis of the new fuels, then move on to charting their performance on a bench-mounted Super Hornet F414 engine before moving on to the big one, an in-flight test.  Some time in 2010, the Navy could be flying high on a more sustainable fuel.

The Veggie Van Organization unveiled the first algae fuel powered car this week in San Francisco. It’s actually a plug-in Prius that has been converted with the nickel-metal hydride battery. The green vehicle doesn’t run strictly on algae, but rather a 5% algae/95% gasoline blend. Since this vehicle uses a standard engine without any modifications, it demonstrates the opportunity to use alternative fuel sources like algae in a vehicle, and only 5% algae might be used today, but it gives some hope for the future.

LanzaTech, a small company based in New Zealand, has developed a proprietary microbe that feasts on the carbon monoxide in waste gas from steel mills and converts it to pure ethanol.  Last year the company launched a pilot facility at the New Zealand Steel plant near the city of Auckland, and its microbes have been happily churning out ethanol without the need for expensive pre-conditioning to remove contaminants.

LanzaTech has found that the same low-cost technology can be applied to biomass syngas, but the real excitement is in the success of this first-ever attempt to capture and convert steel mill waste gas into a clean, sustainable fuel.
