I Am Woman, Hear Me Saw

U.S. Forest Service gets first female chief, trees cower File this under The More Things Change: On Friday, the 101-year-old U.S. Forest Service named its first-ever female chief. Huzzah! Alas, Gail Kimbell is a pro-industry engineer who helped create President Bush’s controversial “Healthy Forests” plan and whose appointment has put conservationists on alert. “She is […]

An old-school method for making gas from biomass

There is a great deal of argument over biofuels, and indeed we don't want to overuse them. But I don't think anyone argues that we can't get some of our power from biomass, or that we won't need a sustainable source of hydrocarbons for chemicals and liquid or gaseous fuels.

I'm going to ignore the usual suspects for a moment to discuss the Fischer-Tropsch process, which uses catalysts to convert biomass to gasoline, diesel, or kerosene (pretty much in whatever ratios you wish). Unlike biodiesel and ethanol, these products are 100% compatible with existing engines in all temperatures, without needing dilution by fossil fuels and without needed engine modifications, even minor ones. The net energy balance is better than for cellulosic ethanol, too.

Is ethanol skeptic Pimentel right after all?

In 2004, the USDA came out with a study (PDF) claiming that corn-derived ethanol delivers 67 percent more energy than it consumes in production. For many observers, including green-minded ethanol critics, the study delivered a resounding “case closed” to the decades-long debate about corn ethanol’s “energy balance.” Critiques began to focus more on the mounting […]

Schwarzenegger wants more

DR: There’s always an emphasis on personal transportation. How do you kick start public transportation and more dense settlements? Did you guys make steps toward that in California? TT: We did. While Prop 87 was going down in flames a week ago, the $60 billion bond package for California infrastructure was passing, with several billion […]

Golden Globe partiers go green

Tonight, you watched a herd of mildly to wildly intoxicated beautiful people congratulating themselves on their artistry, but take heart. At least a small group of them continued the self-celebration responsibly at the "Greenest Party on Earth," sponsored by the Environmental Media Association and E! Television.

Could I have missed this?

I know I'm late on this, but the Wall Street Journal had a report on the 11th about Exxon backing off their position on climate change and perhaps engaging with emissions regulation:

In one of the strongest signs yet that U.S. industry anticipates government curbs on global-warming emissions, Exxon Mobil Corp., long a leading opponent of such rules, is starting to talk about how it would like them to be structured.

One research org says so

I've posted before about Stirling Energy Systems, which sells solar electricity from concentrating mirrors and heat engines for around 11 cents per kWh.

But at least one technical advocacy group -- Trans-Mediterranean Renewable Energy Cooperation (TREC) -- suggests that mass production could bring prices down to 5 cents per kWh or less (PDF), even without technical breakthroughs.

Some clarifications and such

Several issues and questions have come up around the URGE2 concept, most of which I anticipated but was too lazy to write about on my first post. Forthwith, a few notes, caveats, and explanations. First, remember this is conceived as a communication device, not a complete or ideal description of green policy utopia. It has […]

It ain’t pretty

According to this video (below the fold), the Chevy Volt -- GM's much ballyhooed plug-in hybrid concept car -- sounds like a jet engine taking off as it tops out at somewhere between 6 to 7 mph.

Conspiracy theorists, start your engines.

The first step in international action

DR: If you were emperor for a day — or just president of the U.S. — what would your international approach be? TT: No. 1 is to lead by example. When Tony Blair came can sat down with Arnold and I before the summit, he took us aside and said, "Look, what you are doing […]
