I know a couple of folks with gas stoves, and they have trouble with a sticky residue coating their walls and ceiling around the range. They describe it as inherent to cooking with gas. (It's really disgusting.) Yet other folks I know who cook with gas don't report any such problems. Is this a known problem? Any idea why it would affect some people, but not others? Different types of gas (natural vs. propane)? Badly-tuned stoves? Something they're cooking? [more inside]

Are there any environmentally friendly ways to use coal as an energy source? Bonus points if these methods are economically plausible. If none exist currently, is there any interesting research being done?
