JackC 0 #277 July 15, 2009 QuoteI was looking for something that could be used within a vehicle, to remove the carbon from the exhaust before it was released into my breathing air. It might be feasible to build gardens onto industrial complexes to fix the carbon, but I don't think it will scale well to individual users. The problem with using the "communal atmosphere" as a transport device for waste byproducts is that I have to breathe the communal atmosphere. But of itself, CO2 is not poisonous to humans or animals so what's the problem with breathing it? Especially if it saves carting a rain forest around on your roof rack. Now if it was carbon monoxide or carbon tetrachloride your car was belching out, I'd be with you. Quote Share this post Link to post Share on other sites
TomAiello 25 #278 July 15, 2009 Is CO2 the only gas being released into the atmosphere? Plus, how do we know it's not harmful to breathe increased concentrations of it? People thought cigarette smoke wasn't harmful for a long time, too. Heck, the government approved Thalidomide for pre-natal use because it was "safe."-- Tom Aiello [email protected] SnakeRiverBASE.com Quote Share this post Link to post Share on other sites

People thought cigarette smoke wasn't harmful for a long time, too. Heck, the government approved Thalidomide for pre-natal use because it was "safe." No. Typically hydrocarbons get burnt to form water and carbon dioxide, with some carbon monoxide and some stray hydrocarbons for incomplete combustion. Plus anyother crap you get in fuels like traces of sulphur and lead (now largely removed). Now hydrocarbons and carbon monoxide and sulphur dioxide are all pretty nasty and want removing but that's why people invented catalytic converters, to complete the combustion cycle and clean up the exhaust gasses. Volvo for example claim the air that comes out of their engines is cleaner than when it went in. I dunno if that is true though. Plus CO2 has been around in the atmosphere for millenia and it is inert. Quote Share this post Link to post Share on other sites

Well, those pesky old laws of thermodynamics say it would take as much energy to do this as you got from burning the carbon in the first place. Where would you get the energy? (Trees get it from the Sun). It takes around 18,000 kilojoules to breakdown the CO2 produced by burning 1 pound of gasoline).... The only sure way to survive a canopy collision is not to have one.

StreetScooby 5 #284 July 15, 2009 Found mass estimates here: http://blog.phiffer.org/post/27344630/left-all-the-water-in-the-world-1-4087-billion air mass = 5.148 * 10^18 kg water mass = 1.35 * 10^21 kg Using the following equation: Delta Air Temp * Mass Air * Air Heat Capacity = Delta Water Temp * Mass Water * Water Heat Capacity A one degree change in air temperature will equate to 0.0009 degree change in water temperature. Water covers 75% of the earth, so the effect of air temperature changes will be even less than this number. Here's my point: * There are many other factors effecting the earth's weather than how much CO2 is being pumped into the atmosphere. * While I don't condone wanton pollution, CO2 increases will have a insignificant impact on the earth's weather due to any increase in temperature. * The current AGW debate does _NOT_ justify draconian laws that will seriously and adversely effect our current way of life.We are all engines of karma Quote Share this post Link to post Share on other sites

My point is the current AGW debate does _NOT_ justify draconian laws that will seriously and adversely effect our current way of life.

JackC 0 #290 July 15, 2009 QuoteQuote You miss the point ENTIRELY. So, what is your point? The point is that the earth absorbs visible and UV light, which makes it heat up and emit IR light which in turn gets absorbed and reflected back to earth by atmospheric CO2 instead of being allowed to escape into space. This is the greenhouse effect. You conclusion based on calorimetry is invalid because calorimetry is not how the system works. Quote Share this post Link to post Share on other sites

Yes, this is yet another driving force in a very dynamic system, which we do not fully understand. I'm very aware that the earth is only capable of cooling itself by radiation back into space.

What happens if I put two thermally conductive objects in contact with each other and then heat one of them up? The heat flows through both until they are in thermal equilibrium.

In this case, the air cools down. In the calorimetry discussion, the water heats up a little bit, while dramatically cooling the air. If the discussion is really about albedo, let's discuss that.

StreetScooby 5 #297 July 15, 2009 Quote You could try reading your text book from the heat and mass transfer course that you seem to have forgotten about. Your arrogance is simply breath taking. Q = UA * Delta T That covers convective heat transfer, and with minor changes in symbology, conductive heat transfer also. From http://www.engineeringtoolbox.com/radiation-heat-transfer-d_431.html If an hot object is radiating energy to its cooler surroundings the net radiation heat loss rate can be expressed as q = emissivity * Boltzmann constant * (Th4 - Tc4) Ac where Th = hot body absolute temperature (K) Tc = cold surroundings absolute temperature (K) Ac = area of the object (m2) To claim that calorimetry won't be a driving force in this system is simply a ridiculous statement.
