The 41-year-old carbon steal pipe was inspected by an Enbridge contractor for rust in 2004 and cracks in 2005.

Because producing a requisite amount of electricity from gas results in estimate about 50% of the carbon dioxide for the same coal-based electricity, the only way to meet the proposed standard is to capture the outgoing carbon dioxide, pipe it somewhere, and bury it.

If a government-mandated market for pollution offsets ever materializes, the 26-inch pipe hauling away carbon would be able to handle the plant's waste gas and another 5 million tons from other sources in New Jersey.

But they oppose nuclear power, a position that puts them at odds with a fair number of environmentalists who have concluded, reluctantly, that a low-carbon future without nuclear energy is a pipe-dream.

The boy hopped in the snowed-in family car to warm up, but the engine was running and the exhaust pipe was blocked by snow, causing carbon monoxide to accumulate in the car.

The car doesn't need the carbon dioxide to run, so it sends it out the tail pipe and into the atmosphere.

All the proposals envisage a giant pipe starting with a coal plant, but then collecting carbon dioxide from anyone who will capture it before bringing it out to be buried under the sea bed.

AEA's engineers have exploited this reactivity (and also enhanced its effectiveness at exhaust-pipe temperatures, in ways they are reluctant to discuss) to burn up the undesirable particles and other carbon-rich pollutants.
