Nephelios, a solar-powered blimp, is completing test flights over the next 2 weeks in preparation for a crossing of the English Channel by the end of the summer. This will mark the first manned solar airship ever, proving that carbon-free air travel is possible. Flexible solar panels on the top of the blimp will power a small motor, turning two propellers and moving the blimp forward. The flight across the Channel is expected to take less than an hour, and be an amazingly quiet and serene experience for those onboard. You can read more about it here.

Some people swim the Channel, these guys float across.

Thursday, Continental Airlines announced the results of its January 7 biofuel demonstration flight. Not only was the flight successful, the biofuel showed approximately 1.1% greater fuel efficiency over traditional jet fuel. So, not only was the fuel made from renewable sources, it actually beat traditional fuel outright. This type of fuel is estimated to reduce greenhouse gas emissions by 60-80% as well.

Flying the greener skies

“We look forward to working with our partners as biofuels go through the certification process, and we hope to see these fuels proceed into commercial quantities in the near future,” said Leah Raney, Continental’s managing director of global environmental affairs. Hopefully it’s not long until we see all jet fuel from sustainable sources.

The United States Global Change Research Program, a joint venture of 13 federal agencies and the White House, released a study this week confirming that even if the nation takes significant measures to reduce carbon emissions, the impact of global warming is expected to become more severe in upcoming years. Some of the impacts expected are already being seen, including more powerful tropical storms and erosion of ocean coastlines.

Where's my iceberg?

Thomas Karl, director of the National Climatic Data Center at the National Oceanic and Atmospheric Administration (NOAA), stated, “What we would want to have people take away is that climate change is happening now, and it’s actually beginning to affect our lives.” He did continue to say that if we implement controls and measures to reduce our environmental footprint these effects could be significantly smaller.

The study is posted here: http://www.globalchange.gov/publications/reports/scientific-assessments/us-impacts. We encourage everyone to give it a browse if you have time - it’s 188 pages but has good summaries of the effects we’re having on our planet.

Garbage giant Waste Management announced last week at the US Conference of Mayors that it will be distribution BigBelly Solar’s solar powered trash compactor in North America. These units will mostly be sold to municipalities and events venues, and 15 have already been installed at Gillette Stadium in Massachusetts, the new home of the New England Patriots.

Compacting your trash with the power of the sun.

The solar-powered trash compactors look like traditional trash cans, but they are outfitted with solar panels that power a motor that crushes the trash. What does this mean for sustainability? Garbage colleciton can occur less frequently, offsetting carbon emissions by the trucks and distribution network. Small things can really make a difference!

As reported by the Associated Press a few days ago, the wind seems to be dying down across the United States. The cause of this apparent slowing of our winds is still very speculative, as scientists disagree as to whether it’s even happening on a significant scale. But this study does suggest that average and peak winds have been on the decline since 1973, with some stations in the Midwest reporting >10% drops over the course of a decade.

There are enough questions that even the authors won’t say definitively whether the trend is real or not. But, with wind energy as a potential solution to part of the global warming crisis, it’s concerning that the solution might become useless by the problem.

Finding alternatives to plastic has been difficult at best over the past few decades. The problem is that oil is traditionally derived from oil, which both consumes fossil fuels and produces greenhouse gases. Recently, however, scientists at the Pacific Northwest National Laboratory announced a simple process that turns cellulose (plant fibers) into plastic.

Making Plastic From Plants 101

While this process is still quite a ways off from commercial application, it shows promise as a way of creating alternative plastics. With so many of today’s products packaged in some form of plastic, finding a sustainable way to replace our fossil fuel-derived types would have a large impact on the environment, both consumption of fossil fuels and emission of greenhouse gases.
