Burning Ice Drilled from Alaska's Slope 233
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."

Better to burn it before it melts on it's own from global warming (if there is any possibility of that). Methane is something like 23x worse than CO2 as a greenhouse gas by mass.

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.

No, idiot. It's as dirty as it gets. It releases CO2. You didn't do well at comprehension at school, did you?

It would be nice to see a science article linked on
Clathrates have been known about for a long time. Extracting them economically is an interesting interim move to extend the natural gas supply. Here's a nice summary of the potential and problems with this fossil-fuel energy source [energycommission.org], in which the authors somehow manage to convey information and not wilfully and deliberately mislead their readers.

daytime:
6H2O + 6CO2 + energy -> C6H12O6+ 6O2
nighttime:
C6H12O6+ 6O2 -> 6H2O + 6CO2 + energy
But they only respirate out 50% of the carbon they took in - so the net effect is taking in CO2 and turning it into biomass.
