Carbon sequestration trial in Germany

Taxonomy upgrade extras: 

Using Swedish technology, a utility plant in Spremberg, Germany, near the Polish border, has begun capturing the carbon released by the burning of coal for electricity.

First, the lignite coal is being burned in pure oxygen, which makes the effluent cleaner — still carbon-laden but with less sulphur, mercury, and other elements typical to coal burning.

The effluent is then compressed until it is liquid, and injected underground into naturally occurring caverns.

It is pretty tough to excel in a judgment-rated endeavor when you're expected to excel, and that's the situation Barack Obama was in last night — the foundation of all that has grown up in the past four years around him was his keynote speech at the Boston convention.

Even against such high expectation, I thought Obama gave a very good speech last night.

I loved when he said that the election was not about him, but about us. Damn right.

For several years, LEDs were supposed to be the next big thing in consumer lighting, and they're still coming.

But a post this week at GreenDaily touts Electron Stimulated Luminescence as a quicker comer. They are supposed to be equivalent to CFLs in cost and lifespan, but to overcome two of their shortcomings: They use no mercury, and are dimmable.
