  1. November 20, 2009 • Ch. 15 (nuclear) Dustin Reader, a young Cincinnati Bengals fan, was suspended from school on Nov. 9 because of this haircut expressing support for his beloved team. School officials in the Ohio city of Hamilton said they prohibit extreme and distracting hairstyles. Visitors taste Beaujolais Nouveau at the open-air wine spa in Hakone, Japan, on Nov. 19. The Hakone Kowakien Yunessun spa complex launched an open-air wine spa four years ago, and the event takes place every year.

  2. Alternative Energy Sources • Nuclear • In development…(or good holiday dinner conversation) • Hydrogen • Biofuels • Ethanol & biodiesel • Microbial fuel cells http://www.ncpa.org/pub/ba564/ http://www.worldofstock.com/closeups/BEN2002.php http://www.microbialfuelcell.org/Publications/The%20Alchemist%20%20The%20ChemWeb%20Magazine.htm

  3. Nuclear Energy • Fusion = combining • Fission = splitting • 235U fission • Chain reaction releases energy • Burner reactors http://www.cameco.com/uranium_101/fact.php http://nhs.needham.k12.ma.us/cur/mp/step1.html

  4. Uranium Resources • Geology of uranium • Sedimentary rocks • 235U is <1% (238U) http://www.cameco.com/uranium_101/fact.php http://energy.cr.usgs.gov/other/uranium/more.html http://www.eia.doe.gov/cneaf/nuclear/page/reserves/uresarea.html

  5. Other Resources • Reprocessing spent fuel • 238U converts to 239Pu • Breeder reactors • Different technology • Dangers http://www.cameco.com/uranium_101/fact.php http://www.japannuclear.com/nuclearpower/program/waste.html

  6. Pripyat in 2006 Nuclear Power Concerns • Reactor safety • Core meltdowns • Three Mile Island (1979) • Chernobyl (1986) • 400X more than Hiroshima • Thyroid epidemic in children

  7. Road transport of spent fuel in Japan Nuclear Power Concerns • Fuel handling • Exposure during mining • Carelessness • Security http://whyfiles.org/275nukewaste/index.php?g=2.txt

  8. Nuclear Power Concerns • Wastes • Not ‘typical’ toxic waste • Housing material is radioactive http://www.iaea.org/cgi-bin/db.page.pl/pris.agereac.htm http://www.americanprogress.org/issues/2008/07/nuclear_cost.html

  9. Proposed ITER Nuclear Power of the Future • Fusion • “Star in a jar” • Deuterium + tritium = helium • Clean power • Cold fusion http://zebu.uoregon.edu/~soper/Sun/earthnuke.html http://news.bbc.co.uk/2/hi/science/nature/4627237.stm http://www.seas.columbia.edu/apam/hbtep/Pictures/slides/tn/nuclear_fusion_dt_reaction.png.shtml

  10. Standard H2 fuel cell car Hydrogen http://www.afdc.energy.gov/afdc/ http://www.nrel.gov/vehiclesandfuels/whatis_fuelcell.html http://www.sustainability.dpc.wa.gov.au/CaseStudies/Hydrogen%20Fuel%20Buses/Hydrogen%20Fuel%20Cell%20Buses.htm

  11. Hydrogen in the Home • Solar energy • Split water • Hydrogen • Use for electricity • Water • Recycled for splitting • 3 L is it! • Developing nations
