* A 1,000 MW(e) coal plant uses approximately 400 tons of coal per hour.
* A 1,000 MW(e) coal plant generates about 5,000 tons/hr of combustion products. About 80% of that is nitrogen from the combustion air.

If successful, the new chemical treatment would mean thousands of coal-burning plants worldwide could sharply curtail carbon emissions...
Analysis by his other company, Envirolution Systems, suggests a market potential of $700 billion worldwide for existing coal plants alone.
"It could be the first homegrown billion-dollar business in Colorado Springs," Neumann said.
After achieving success in lab tests, Neumann approached Springs Utilities about testing the process on one of the city's power stations. The testing, which begins today, will attempt to remove emissions on the equivalent of one-tenth of 1 megawatt at a 46-megawatt unit at Drake.

How cheap is coal? Not very when you factor in childhood asthma, etc
Coal seems cheap compared with "green" technologies such as wind power, he said [Ontario Energy Minister Dwight Duncan], but it comes with other costs. "I tell you the most expensive thing is the rates of childhood asthma, the rates of air pollution and our failure to come to terms with this," he said.

Preliminary generation data from DOE for 2002
Total US electricity demand increased by 2.7% in 2002 compared to 2001. Coal-fired output rose 1.2 percent. The electricity mix looked like this:
Coal - 1,905 billion kWh
Nuclear - 780 billion kWh
Gas - 601 billion kWh
Renewables - 292 billion kWh

* Coal plants much cleaner today - 3X more power with 1/3 drop in emissions in 30 years
* Construction lead time - nukes = 8-10+ years, coal = 5-8 years, gas = 2-4 years
* Electric plant capital cost thumbrule - coal is double gas, nuc is double coal
