A short primer for students before starting assignment Greenhouse Gases Infrared Light Absorbtion Thermochemistry Global Warming / Environmental Ecology
What do the sun’s energy, a molecule’s shape and a TV remote have to do with greenhouse gases?
Infrared Absorbance TV Remote
Infrared Absorbance Sample TV Remote
What is a greenhouse gas?The sun’s energy & the molecule’s shape decide. http://zebu.uoregon.edu/1998/es202/l13.html • Our atmosphere (air) is 78% nitrogen and 21% oxygen. • Neither absorb infrared radiation (heat) and are greenhouse gases. • H2O and CO2 and other gases do absorb infrared energy and without them earth would much colder.
Combustion of fossil fuels are contributing to the rise: • CxHy+(x+y/4)O2x CO2+y/2 H2O + Energy
CxHy+(x+y/4)O2x CO2+y/2 H2O Combustion Energy = Carbon http://chemistry.beloit.edu/Warming/pages/emissions.html
CxHy+(x+y/4)O2x CO2+y/2 H2O The Gas Combustion Engine
Infrared Spectra: CO2 Concentration Effects Nitrogen & Oxygen produce flat lines: 100% Transmission, 0 Absorbance
Human factors increase CO2 Correlating Mauna Loa, Hawaii with 8 other global sites Direct atmospheric CO2 measurements and reconstructions from measurements of air bubbles trapped in ice. http://www.whrc.org
Nuclear Reactions: Fission: Fusion: • Fission and Fusion reactions are highly exothermic (1 Mev / nucleon). • This is 10 6 times larger than “chemical” reactions which are about 1 ev / atom.

Nuclear Reactions / Fusion • Fusion has been described as the chemistry of the sun and stars. • It too has been used in weapons. It has not yet found a peaceful commercial application • The application has great promise in producing relatively “clean” abundant energy through the combination of Hydrogen isotopes particularly from 2H, deuterium and 3H, tritium: (NIF/National Ignition Facility, LLNL & ITER, France)

Solar Energy Earth absorbs approximately 3,850,000 exajoules (EJ) per year [Exajoule (EJ) = 1018 J = 278 TWh] Total 2012 world energy consumption was estimated @ 559.8 EJ
Solar Energy North America’s solar potential 181 to 7,410 exajoules (EJ) per year [Exajoule (EJ) = 1018 J = 278 TWh] DC AC Without battery Home solar array Google’s Project Sunroof: https://www.google.com/sunroof
Solana Bonus: The heat from a solution of molten potassium & sodium nitrates is used to store the energy, which turns a turbine in 6 hrs of darkness/ day. $ 2 billion 3 years 2,200,000 m2 2,700 mirrors 280 MegaWatts 70,000 homes - 475,000 MT CO2 Equivalent http://www.youtube.com/watch/?v=G1hdoWk17wU
