Thanks for the links krobert-ga. They were helpful.

I disagree with your statement that :
"It is physically impossible for the heat GAIN (thanks kemlo) through
the walls of the refrigerator to change due to the changed contents"

Consider the "content" I put into the refrigerator being a solid
block of insulating material that fits perfectly into the rectangular
area of the fridge. Or for that matter just a rectangular shell of
insulating material that fits into the fridge and effectively doubles
the thickness of the insulating walls. This would be an unusual 
"content" but it should decrease the heat GAIN into the fridge and
thereby reduce energy cost.

I do agree that beer cans, even when fully stocked in the bridge, 
will not have quite the same effect (and quite possibly
have no effect on the heat-transfer rate) :-)

Interesting but not what I asked.  I am needing to know threshold of
"annoyance" not hearing damage.  I have Beranek material.  Simply put:
 What level of low frequency rumble starts driving people "crazy".

Thanks, Krobert-ga. As I suspected, there is indeed some NOx emission
from a hydrogen powered ICE. It is a lesser amount than a conventional
ICE (assuming the Ford engineers aren't fudging). The pollutants
resulting from construction are not relevant to operation. A
stoichiometric feed would require N-free oxygen supply...we can forget
about that. Apparently fuel cells are the few truly non-polluting
power sources known...if you don't mind waiting two hours for them to
warm up.
  I feel obliged to comment on your comment about we humans producing
CO2 and thus contributing pollution. Actually we, and all air
breathing animals exhaling CO2 have derived our carbon intake from
matter which has captured CO2
from the atmosphere somewhere in the food chain. Thus it is a
steady-state process which is in balance. It used to bother me that
our breathing increases the quantity of CO2 until I learned the above.
Similarly,trees and vegetation in general are touted as CO2 sinks but
actually are not. When a tree dies and decomposes, all its carbon is
released back to the biosphere. Just another example of conservation
of matter and energy.
Thanks,

This has been the best "answer man" I have had the pleasure to
question, even though he's in his left mind. I will specify him in the
future 10 stars!

Im not exactly sure what a DBA is.  Is this so people can open a store
front under false names?  Well, what if the person IS doing business
under their real name (thus dont have to file a DBA)...how would I
find their name using the name of the storefront or address of the
store?  At any rate, you steered me in the right direction.  Thanks.

thanks so much:)

My question was not answered, but the discussion surrounding it was
well worth the price.

Do I need to pay more for a real answer?

Dear Krobert,

This is the first time using this Google thing so I apologize for not
getting back with you sooner.  I do thank you for your quick post and
the information you supplied.  I'm now on my way to building a
prototype that will change the world! lol

Thanks again,
Joe1

krobert gave me the basics with a bit of resistance to find a more
complete answer.  I thought that this was a basic (relatively easy)
question for a general scientist.  Every day that I find the time to
search, I find many more fields of study (soft and hard) than he
bothered to list in his second answer.  AND, I never learned if 'hard'
or 'soft' were terms used to reference the study of the 'sciences'
today.  Plus, I did not receive a list of any courses / fields of
study in the "soft" sciences. So, ultimately I don't believe that my
question was answered.  I would, however, be greatful for any thoughts
on how I could have phrased or worded my answer to get a better
result.

exactly the answer i was looking for, though  i would understand that
on my own, but what i really wanted was what and how do i get good
credit?

I was not too satisfied with the answers. However, the researcher
Krobert-ga was polite and tried his best.
