... and can't find with a simple Google search.

I've been thinking about starting this for a while. Sometimes I have questions but I don't have "a guy" with relevant knowledge, but it bugs me.

Q1, 8/4/14:
-a) In thermal imaging of humans, the rib cage is so hot, it's usually shown in a fair amount of detail. Do ribs act as a heatsink (partially to transfer heat to the other, bigger heatsink, the skin)?

b) If so, is the rib cage's ability to act as a heat sink a necessary function in the human body under normal circumstances?

c) Is there any long-term benefit to keeping the heart cooler than its normal heat dissipation mechanisms do? -Or does heart function decrease?

d) If heart function increases if cooled beyond what the body is normally capable of in normal circumstances, would there be benefit in replacing natural ribs with, say, thermoplastics?

Q2, 8/4/14:
-Roughly how much wind energy is generally outputted by the sun? Grin

Q3, 8/4/14:
-Given waves generally (all?) generate some kinetic force, how much force is generated from, say, a cell phone with, say, four 100%-efficient 200mW cell radios operating at 1.8GHz? An explained formula would be greatly appreciated.

Q4, 8/4/14:
-a) Why do we use antennas/boosters for such specific ranges of frequencies? If there is any, what would roughly be the percentage loss in range if a cell phone used only one antenna, 300-2000MHz in range, rather than using many specialized antennas deviating no more than 100MHz in range? Does this loss of range/power still apply even if the antenna can dynamically change which frequencies it's actively listening and sending on?

b) Given quartz-timed CPUs and the like slightly deviate in frequency from what they "should" operate at, would an antenna with a set 100-200MHz range (with no MoE, so it's not "actually" set to be, say, 99-201MHz) have difficulty consistently picking up and sending out a 100MHz and 200MHz frequency?

Same here with: Why does Jell-O do what it does? (The answer has nothing to do with Jell-O or Bill Cosby.)

There are really specific questions that demand deep knowledge in the fields.
So better ask to an expert, or join a specialized forum, because I doubt there are people here willing or able to answer.

Maybe. I've found a wide variety of experts in the community on ALMOST everything. What I've actually always done is to just contact a corporate or standards-producing-organization directly, and oddly enough, someone always seem to have time for me, but it seems like a waste to have them only explaining to a single person instead of having it public - but jeez, I'd have to register on so many separate forums for all these nagging questions.

I was thinking about offering bounties, but I'm far too poor, really, so I'm hoping to cash in on a positive question-answering balance.

(clarification on Q4b: I didn't mean to ask what I did. I meant to ask if transmitters and receivers tuned to a specific frequency would be unreliable if it weren't given a range within a MHz or two, not the antenna.)

How about everytime you puke there's always carrots in there even when you haven't eaten any.
