no shit , i've known that for years

yes the materials on the earth may be able to be estimated, but it's only a number, and I don't know what point ur trying to make again

86tt wrote on Tue, 13 September 2005 16:03 | When you say the world have limited amounts of material I would certainly disagree, because the amount of mass underneath the earth's crust is unimaginable

you said you couldn't imagine it, i said it could be measured AND IS FINITE.. sheesh...

and yeah, so you mentioned fuel and oxygen will make it ignite (I assume you know it's called a chemical reaction?) and with a catalyst, it will react at a lower temp., so? Turning water into H2 and O2 is a chemical reaction, and I said that I've heard a rumour that a catalyst can help this chemical reaction, is it quantum theory? No, is this too hard for you to understand? I hope not...
|
che.. chemi... whu???
dude... i have a PhD in Metallurgy, my thesis was based on thermodynamics, diffusion and chemical reactions
turning water into 2H2 and O2 is a chemical reaction... but it is not energetically favourable. this is because a) you are reducing entropy, and b) you are absorbing enthalpy (and turning it into chemical bonds).
ie it TAKES energy to split water.. it doesn't happen spontaneously, even in the presence of a catalyst..
in fact, this is not completely true.. at high enough temperatures, water will break down into it's components, but at more than 1000C, there is plenty of energy to convert it back into water (oh, i use water to control oxygen partial pressures in oxidation reactions too .. forgot to mention that before )
the problem here, is that you don't seem to understand basic thermodynamic fundamentals, and you continue to ignore them..
please go and do a quick calculation of the gibbs free energy of the reaction of water into it's constituents... i can tell you now that it will be positive

Did I say I want to take the heat from outside and put it into a room in summer? You're imagining things...
|
you actually said....
86tt wrote on Tue, 13 September 2005 16:03 | I think you are fairly close, and this system is called a "heat-pump", but is set up in a very inefficient manner (taking heat from a not-so-hot room, and dumping it into a "hotter" room)
What if you do it the other way around? ie. Taking heat from a very hot place, and dumping it into a very cold place?
|
taking heat from a very hot place and putting it in a very cold place is usualyl called either:
a) a radiator on a car
or b) opening a window.
neither of these situations has any relevance to AIR CONDITIONERS, to which you were alluding.
a little bit of knowledge is far more dangerous than a bucket load of ignorance...
unfortunately my friend, you have both.
