Clean Coal - Pipe Dream Or Next Big Thing?
Coal Industry Launches Ad Campaign To Support Energy Alternative, But Some Say Technology Hasn't Caught Up Yet

But, as CBS News correspondent Wyatt Andrews reports, utilities are testing technology to make one of America's most abundant fuel source - coal - a cleaner alternative.
Coal is, by far, the dirtiest way America makes its electric power, but a new ad campaign funded by the industry promises a future where clean coal is a viable option.
And it's not just the industry. Both presidential candidates, Barack Obama and John McCain, are pushing clean coal.
But exactly what is the technology?
The cleanest coal plant in North America is operated by Tampa Electric, in the middle of rural Florida. They call it clean because they don't burn coal exactly - they mix it with water and oxygen and convert it into a gas.
According to company president John Ramil, gasifying coal allows the company to remove pollutants like sulphur, nitrogen and soot, which virtually eliminates acid rain.
"And you can do it much cleaner than with the conventional coal technology," says Ramil.
That's the good news. But here's the problem.
"There is no such thing as clean coal," says James Hansen, NASA's expert on global warming, who says all coal plants, even TECO's, still emit millions of tons of carbon dioxide - the most threatening greenhouse gas.
"There is no coal plant that captures the carbon dioxide and that's the major long-term pollutant," says Hansen.
But if carbon dioxide pollution is the problem with clean coal, many scientists believe there is a solution. They believe it's possible to recover most of the carbon dioxide and store it underground.
The idea is called "capture and sequester," and a global race is on to learn how it should be done. One Norwegian firm is storing tons of carbon dioxide in rock caves beneath the North Sea. America's efforts to sequester carbon have stalled. The Department of Energy planned to fund a plant, but pulled all funding when the price grew too high.
"They took seven years just to decide where they were going to make a pilot plant - and then they decided to cancel it," says Hansen.
And now, the failure to solve the carbon dioxide problem is a threat to coal itself. In the last five years, at least 63 coal-fired power plants have been scrapped or defeated by public opposition.
Florida Governor Charlie Crist helped pull the plug on the two clean coal plants because he says without a carbon solution, clean coal is not an option.
"Until that time comes, we want to develop more solar, more nuclear, more wind," says Crist.
Which is why the industry needs an ad campaign. Until the federal government funds the research on carbon dioxide, America's reliance on coal is in long-term trouble.

We Can make ''Clean Coal'' technology work,...there`s an abundance of coal here in our country,..between,the wind,the sun,the water,...and everything else we have,..Surely we can harness enough power to serve our people ,..

We sure can, but it doesn%u2019t go to our people. It is more cost effective to export our power production resources than to use them here.
Why are people so dead set against alternative energy used in concert with "dirty" power? Keep burning your coal and build a wind tower in my back yard...the near-constant wind here in E. New Mexico will keep it running. Build a nuke plant next door...ask the French how to deal with the waste. Put solar cells on my roof...let then excess run off into the grid...I won%u2019t charge for it. Hydroelectric won%u2019t work here...no water. Sell me a fuel cell car at a normal price...the algae will produce the hydrogen. Keep producing gas for a decade or so until most of the ICE cars are in the scrapyard.
Appearing before the Commons Committee on Environment and Sustainable Development last year, Carleton University paleoclimatologist Professor Tim Patterson testified, "There is no meaningful correlation between CO2 levels and Earth''s temperature over this [geologic] time frame. In fact, when CO2 levels were over ten times higher than they are now, about 450 million years ago, the planet was in the depths of the absolute coldest period in the last half billion years." Patterson asked the committee, "On the basis of this evidence, how could anyone still believe that the recent relatively small increase in CO2 levels would be the major cause of the past century''s modest warming?"
Patterson concluded his testimony by explaining what his research and "hundreds of other studies" reveal: on all time scales, there is very good correlation between Earth''s temperature and natural celestial phenomena such changes in the brightness of the Sun.

"The Inconvenient Truth" is indeed inconvenient to alarmists
By Tom Harris
Monday, June 12, 2006
"Scientists have an independent obligation to respect and present the truth as they see it," Al Gore sensibly asserts in his film "An Inconvenient Truth", showing at Cumberland 4 Cinemas in Toronto since Jun 2. With that outlook in mind, what do world climate experts actually think about the science of his movie?
Professor Bob Carter of the Marine Geophysical Laboratory at James Cook University, in Australia gives what, for many Canadians, is a surprising assessment: "Gore''s circumstantial arguments are so weak that they are pathetic. It is simply incredible that they, and his film, are commanding public attention."
http://www.canadafreepress.com/2006/harris061206.htm
The Oregon Institute petition says, in part:
"There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the earth''s atmosphere and disruption of the earth''s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the earth."
Robinson noted roughly 35 new signatures are added to the petition every day. Signers include more than 40 members of the National Academy of Sciences. Theoretical physicist Freeman Dyson and atmospheric physicist Richard Lindzen of the Massachusetts Institute of Technology are among the prestigious scientists who have signed the petition. Frederick Seitz, the first president of the National Academy of Sciences, signed before his death in early March.

ummmmmm how many climatologist support al gorebage BS... LOL
Robinson said, "The very large number of petition signers demonstrates that if there is a consensus among American scientists, it is in opposition to the human-caused global warming hypothesis rather than in favor of it."
Added Joseph Bast, president of The Heartland Institute and publisher of Environment & Climate News, "Claims by partisan and extremist organizations such as Greenpeace, the Natural Resources Defense Council, and the Union of Concerned Scientists that their views represent the ''consensus'' never should have been taken seriously.
"They are not scientific organizations, and in fact they have long records of misrepresenting science to achieve political objectives," Bast said. "This should go down as yet another case in which they were caught lying about science."

Wow, that''s alot of scientists, terrorislami!
How many of them were climatologists? (ya know, cuz that''s the subject matter they were pontificating about)
You strike me as the kind of person who''d ask a climatologist what strain of peas to plant in his garden.
Check out the big brain on brian%u2026 lol
Jules: Do you know what they call a Quarter Pounder with cheese in France?
Brett: No.
Jules: Tell him, Vincent.
Vincent: Royale with cheese.
Jules: Royale with cheese. Do you know why they call it a Royale with cheese?
Brett: Because of the metric system?
Jules: Check out the big brain on Brett. You one smart ************.

china is building many many coal generating plants,,,
we can buy electricity from them,,, LOL
so much for your global warming BS gorebage,,,
1) Coal could be clean if they''d run the flue gases through columns of water with algae in them. The algae will capture 20-40% of the CO2 and over 85% of NO (which is a worse greenhouse gas).
2) There is no evidence that water vapor is a greenhouse gas.
