Burning Ice Drilled from Alaska's Slope

bagboy writes to tell us that as sources of renewable energy are being sought, BP has announced a new method of extracting natural gas from ice underneath Alaska's North Slope drilling fields. "Scientists with the federal Energy Department paid $4.6 million to drill for the hot ice just below the surface of the Milne Point well, which is situated northwest of Prudhoe Bay. [...] Now, scientists from around the world are waiting for pieces of this strange ice to conduct their own tests and determine whether Alaska's frozen grounds contain untapped, clean-burning energy."

      At any rate, it's not as if there's a shortage of natural gas in Alaska. There are vast quantities in the Prudhoe Bay fields; the problem is that without a gas pipeline, there is no way to get it out of Alaska and to market. There is a lot of interest in building a pipeline, but you can imagine the various considerations- environmental impacts, terrorism threats, negotiating terms with the Canadians and Native American peoples in order to cross their land, what cut the state gets of the revenues- so it's not happening immediately. However, it will eventually happen if energy demands keep growing the way they have been.

      Clean burning fuel has nothing to do with C02, but everything to do with nitrogen and sulfer compounds, often call NOx and SOx ("x" because the number of oxygen atoms varies depending on the species). Those two classes of compounds are responsible for smog, acid rain, and, in part, the ozone layer depletion. Given the choice between burning, say, coal, which produces an excess of NOx and SOx, and methane which produce only traces of same when properly combusted, I'll take the methane, thank-you-very-much.

      Well, "clean" and "environmentally friendly" aren't always the same... Methane burns cleanly, pretty much as cleanly as combustion can possibly get. "Clean" here is implying "without partial combustion byproducts that result from burning gasoline, diesel, biodiesel, wood, or pretty much any other organic substance". So in the sense of what we traditionally think of as pollutants, the noxious fumes that come from your car's tail pipe, it's clean. Is it going to reduce greenhouse gasses? Well, not so much.

      So it turns out that this particular find is not a solution for global warming. Yet if we are going to continue burning organic materials for energy, and we assuredly are for the next decade at least, then I'd rather it be a "clean" burning hydrocarbon.

      In hydrocarbons burning the hydrogen provides most of the energy. Burning the carbon provides some, but the carbon is mainly useful for packing the hydrogen in a form more dense than H2 gas for convenient storage and handling.

      As hydrocarbons go, CH4 has a higher ratio of hydrogen to carbon than any other molecule: Every bond on every carbon holds a hydrogen, none are "wasted" connecting to other carbons.

      So if you're going to burn hydrocarbons for energy, methane releases the least CO2 for a given amount of energy produced.

Failing to do so will only result in more reliance on Coal and even worse ecological damage as we rip up the Earth for Tar Sand and Oil Shale. Oil is a passing fad.

    No. Only releasing CO2 that has been locked out of the ecosystem for an extended period of time affects climate change. All the rest is already factored into the system, and simple cycles around between plants and animals.

    Well, in that case, let's kill all the animals. Dogs, cats, cows, every last one. After all, they're creating dangerous CO2. And then we can all starve to death and we'll die too. That should teach us for breathing. *cough* :P

    That's the standard line from the pro-oil PR companies, yes. But it's absurd. The CO2 already in the ecosystem, as I pointed out above, is not contributing to climate change. It's in balance already. The old 'cows farting' line is quite warn out, and completely discredited. Only *new* sources of CO2, such as those locked up in fossil fuels, and which therefore add substantially to the atmosphere when burned, contribute to climate change.

    just exactly what does "Justice for Palestine " look like, and what the $%@$%# does it have to do with invading Iraq for oil?

    Good question. It means the right to their own land, for one thing. It means a dismantling of the terrorist, fundamentalist state of Israel and replacing it with an inclusive, secular state ( which Palestine was prior to 1947 ). It means the right of return for all Palestinian refugees - something which the Israelis have always argued Jews should have, regardless of whether they've ever actually lived there before.

    As for what it has to do with oil, it's simple. Israel is funded and supported by the US to keep their watchdog in the area. If you remove the US's ability to grab oil in the Middle East, suddenly Israel becomes nothing more than a horrible liability. Once US support is removed from Israel, it will collapse, and Palestinians will be able to move forward to a just single-state solution.

    Your quote from God-knows-where lacks any real connection to the issue. You are trying to point out that there are some Muslim extremists. I don't deny that. But I do point out that it is our policies which are creating these extremists, and that we also have our share of extremists. The fundamentalist Jewish position ( Zionist ) is equally as harsh against others and humanity as your quote suggests of Muslim extremists.

    If it is the the total destruction and removal of a race, and total religious and political domination by Islam through a violent and bloody war. I would say that your views don't match what you are saying, and you are supporting the most extreme and oppressive ideology that has ever crossed our planets surface.

    Israel was founded on just such principles. The dominant Palestinian position has been far more moderate, even to this day. Keep in mind that Israel carried out mass genocide against the Palestinians, and treat them as aliens in their own land. 50 years of this kind of treatment will of course create a lot of people who are angry, to say the least, with their occupiers. But it is a lie to suggest that the Palestinians want the 'total destruction and removal of a race'. What they want, and what they voted for when electing Hamas, is the total destruction of the state of Israel, which is a different thing to the destruction of a race. The racist fundamentalist state must go. The Jews who want to remain in the area can do so, but under a secular Palestinian state.

    The Israelis and the US, however, are not interested in a single-state solution, but instead push for a so-called 2-state solution, which in practice has meant continual erosion of traditional Palestinian land, continual escalation of violence, continual increasing in illegal 'settlements' in Palestine, an Appartheid wall that cuts up Palestine into tiny, inaccessible islands in a sea of Israeli occupation, trade barriers, etc, etc, etc. This 2-state solution has been tried for many years under Arafat, and as failed. This is why Hamas has come to power - because Palestinians understand that there simply can be no dealing with Israel - that they will continue to erode Palestine until it doesn't exist.
