photo Scientists at Georgia Tech have developed a way to use hamsters as a clean source for renewable energy.  (Well, “clean” is up for debate.  Those little rodents can get smelly.)

To harness hamster power, the scientists sewed electricity-generating threads one-fiftieth the width of a human hair into a yellow jacket worn by the hamsters as they ran. A human-sized jacket, capable of powering an iPod, could be ready in as little as three years.
“This can totally be scaled up,” said Zhong Lin ‘ZL’ Wang, who co-authored a paper describing the research in this month’s issue of Nano Letters. “This is just the first step. The idea is that we would harvest energy from any body movement, from walking, breathing, from any kind of vibration.”

CNN interviews Joe Lucas, the spokesman for the American Coalition for Clean Coal Electricity (via Reality Blog):

[Question:] Can you just answer that yes or no? If you believe that burning coal causes global warming?
[Joe Lucas:] I don’t know, I’m not a scientist.

Echoes of the time not so long ago when tobacco chiefs claimed, in testimonies before Congress, that cigarettes aren’t addictive.

link "It's Time for Cities to Favor People, Not Cars"

That was the message transportation planner Timothy Papandreou brought to “Expanding the Vision of Sustainable Mobility,” a symposium sponsored by the Art Center College of Design. The school could be called the Harvard of transportation design, and two-day conference drew experts in fields as varied as urban planning and aerospace engineering to discuss where the future of mobility lies.

Papandreou called for an end to “state, federal, and local land use policies that are literally forcing people to have to drive” and told Wired.com we’re on the cusp of an inevitable “mode shift” away from individual car ownership toward a greater reliance on mass transit and sustainable transport.

“We’re already at that crossroads,” he said.

photo Can’t say this bums me out.  Corn ethanol is a bridge solution, and I think we’ve passed the bridge. From the NYT:

Barely a year after Congress enacted an energy law meant to foster a huge national enterprise capable of converting plants and agricultural wastes into automotive fuel, the goals lawmakers set for the ethanol industry are in serious jeopardy.
As recently as last summer, plants that make ethanol from corn were sprouting across the Midwest. But now, with motorists driving less in the economic downturn, the industry is burdened with excess capacity, and plants are shutting down virtually every week.

2 tragedies, 1 glimmer of hope

In the Australian state of Victoria, at least 135 people have died and 750 homes have been destroyed in fires.  It may not be the case that global warming is to blame for the fires (official suspect arson), but a hot and dry climate is certainly not helping.

Near Chicago, 65,000 gallons of oil sludge spilled from a holding tank at a Caterpillar facility and contaminated a 3-mile stretch of the Des Plaines River.  The combination of under-served infrastructure and overzealous manufacturing is certainly a factor.

But here’s the good news: as a result of high gas prices last summer and the nationwide recession, which spurred people to drive less and drive more slowly, traffic deaths were down 10% last year.

The price of gas was the result of myriad market forces, but it led to rational behavior that was good for people and the planet.

And that gives me hope.  (So let’s tax the hell out of carbon!)

Smarter transport, please

Last year, the average American wasted $1,000 of gas and emitted thousands of pounds of carbon into the atmosphere because of clogged roads and highways.

link If Global Warming is to Last 1,000 Years, Why Cut Emissions?

A recent study found that given current greenhouse gas levels in the atmosphere, we’ll be feeling the effects of global warming for at least the next millennium.
