James Howard Kunstler, or as we like to call him, Jim, tackles six questions from the listeners of Two Beers With Steve. Questions range from social unrest to finance to, of course, Peak Oil. Too bad we ran out of time for a sort of Behind The Actors Studio style of rapid-o questioning. Maybe next time.

KunstlerCast- JIm's very own podcast that he does with Duncan Crary where they explore a multitude of topics and give us all an example of a what good conversation once sounded like.

Ok, here is the problem As shown in the eqiatuon below, nitrogen oxide, NO, is common pollutant that is produced by the reaction of nitrogen and oxygen gases. Since these gases are the major components of air, nitrogen oxideresults when air is heated in furnaces, motor engine cylinders, or other high temperature combustion areas. N2 (g) + O2 (g) < => 2 NO (g)A. Given that the standard enthalpy of formation for NO2 (g) is 90.25 KJ/mole and using the absolute entropies listed below, calculate the free energy change for this reaction at 25 degrees celcius. Is this reaction product favores at 25 degrees celcius? Absolute entropiesN2 (g) 191.5 J/mol times K O2 (g) 205.0 J/mole times KNO (g) 210.7 J/mol times KB. If the reaction is not product-favored at 25 degrees celcius, determine under what conditions it would be product favored.Show ALL work.Thanks for any help I can get! http://ddisevmhwt.com [url=http://dzebea.com]dzebea[/url] [link=http://pqnofgcul.com]pqnofgcul[/link]

all valid, especially the green prctouds, with one critique i hope the building code never becomes prescriptive on the percentage of area dedicated to glazing (beyond ordinances in certain neighborhoods for streetfrontage). it's possible to have 2000 (or 10) windows oriented properly that are (in sum) energy positive: triple pane windows with ultra low u-values, high SHGC values, shaded properly to avoid summer overheating that wouldn't be an energy suck. might be a bit of an economic and construction timeline nightmare, however.passivhaus relies on this principles for balanced energy: sum of heat losses (ventilation losses + heat loss through envelope, etc) = sum of heat gains (solar gains + process heat)it'd be interesting to know if all those windows are north facing and are actually an energy suck. given the climate of australia, they might not be. though overheating may be an issue given the lack of external shading it would be nice if the energy code actually required windows and walls to have better u-values and optimized SHGC levels to significantly reduce CO2 levels (and energy bills).
