Chevrolet Volt
General Motors' all-electric Volt to reach consumers in late 2010

General Motors is quite confident these days. The company recently priced its highly-anticipated full-size hybrid SUVs and showed off a concept version of its full-size hybrid Chevrolet Silverado. GM CEO Rick Wagoner also noted that his company will release one hybrid per quarter for the next four years -- lofty goals indeed.

Likewise, the company's brand new Chevrolet Malibu mid-sized sedan has been generating an overabundance of praise and its new $32,000 second-generation Cadillac CTS just walked away with Motor Trend's Car of the Year award.

GM is hoping to use this momentum and high level of interest in its vehicles to push the electric motor-powered Chevrolet Volt to customers by the end of 2010.

GM vice chairman Bob Lutz has heard all of the critics who question GM's aggressive ramp for the Volt, but is still committed to moving forward.

"There is a lot of skepticism within the company about the timeline," said Lutz. "People are biting their nails, but those of us in a leadership position have said it has to be done."

GM is hoping to use the Volt as a halo car to further strengthen its brand and its commitment to fuel economy. Dodge used the Viper to enhance its image for performance and styling in the 1990s. Toyota used its Prius at the turn of the century to shroud the entire company with a green image despite the fact that gas guzzlers like the Tundra and Sequoia share the same showroom space.

"When they think of GM, the iconic brand is, unfortunately, the Hummer," continued Lutz. "That perception needs to change.

The GM Volt features a 1.0 liter, 3-cylinder gasoline engine which is solely used to recharge the onboard lithium-ion battery pack. The battery pack, which will be manufactured by Compact Power and Continental Automotive Systems, powers the Volt's electric motors for forward propulsion.

GM says that the Volt can travel for up to 40 miles on battery power alone. After the 40 mile threshold has been reached, the gasoline engine kicks back in again to recharge the battery pack.

The entire industry has its eyes on GM and its Volt. Toyota took a big risk with its Prius and it has paid off dearly for the company.

"We have since realized that letting Toyota gain that mantle of green respectability and technology leadership has really cost us dearly in the marketplace," Lutz added. "We have to reestablish GM's leadership and the Volt is, frankly, an effort to leapfrog anything that is done by any other competitor."

Unless you are in a third world country coal power plants do not emit polution in the way you apparently believe. US coal power plants, like the one I lived a few miles from my whole life, have what is known as scrubbers which reduce take out 99.7% of all sulfer from the fires. All (if not almost all) of the material that burns or emitted from the fires is collected into what is known as fly ash, which is rather safe I assume as we used it to cover C-stone drive ways/roads on farms (good at keeping dust down on C-stone or gravel).

What you see come from those power plants are steam not smoke. I have not seen information on if these clean coal plants put out CO2 or not, or how much, so I cant comment on that.

At last check only about 25% of all coal power plants in the United States have scrubbers on them. The remaining 75% are pumping a LOT of their waste into the air we breath.

This IS changing though, new regulations are finally forcing more and more plants to install scrubbers.

As for "clean coal" plants (aka "less dirty coal"), they generally emit little other than CO2 in their flue gas, and not even that if they use sequestration (though that is unlikely if/when large scale deployment occurs since sequestration is expensive). However they do this because they've already taken out the pollution in coal and captured it in waste water instead. Clean air, dirty water. Possibly not a bad trade-off since the water is easier to purify of pollutants. However calling the process "clean" is still a misnomer if you ask me, just less dirty.

Problem nowadays (and why Coal is starting to by attacked by our state government and governor) has not to do with traditional sulfur and the like, but the new global warming anti-carbon attack. Burn carbon based stuff (including coal) and you get carbon dioxide in the air which is what they're against -- "scrubbing" doesn't get rid of the CO2.

My dad has worked in a coal power plant in western South Dakota for as long as I have been alive (30 years). He stated that most of the power plants around the central plains have a recycle system (not an official scrubber) that recycles much of the pollution into a generator system that produces a bit more power from it before being released. Some of their most recent studies indicated this is much more efficient and better for the environment than the "scrubber system" you mention.

Perfect example of what it does as the primary pollution output industry in the area:

Pollutant: Particulate Matter (PM10) Weighted Annual Mean at 2 sites: 21.3 µ/m3 in 2005 (it was 26.4 µ/m3 in 2000, 32.5 µ/m3 in 1990).
Pollutant: Particulate Matter (PM2.5) Weighted Annual Mean at 2 sites: 7.4 µ/m3 in 2005 (it was 8.3 µ/m3 in 2000).
