  2. 1957. Gell-Mann and Rosenfeld. Ann. Rev. Nucl. Sci. and UCRL 8030 by Barkas and Rosenfeld. • 1st update of 8030, with original wallet card. Then no revisions until 1961. • Several new baryon and meson resonances • Discoveries were pouring in. Decided to comuterize. TABSU Galtieri, Bastien, Kirz, Rittenberg Tried to pick resonances with a 90% survival probability. TWO wallet cards. Matts Roos (Copenhagen) published his tables in RMP, with 21 resonances which did not survive to the next edition. • Merged “Data on Elementary Particles and Resonant States” Rosenfeld, Barbaro-Galtieri, Barkas, Bastien, Kirz, Roos, 27 pp. 3 wallet cards, available in two sizes Dave Jackson advised us. • Started printing in both CERN and Berkeley. Rare statistical fluctuations become commonplace. 1000 physicists scan 10,000 -20,000 mass histograms/year. Gerry Lynch invents “GAME” A Monte Carlo resonance generator

  3. At the 1967 Philadelphia meson conference Rosenfeld pointed out that at the present rate of data processing, once attention had been drawn to the Kappa, it should be observedyearly at the 3 Standard Deviation level. Comparison with flying saucers, or cancer from EM fields. “In the next talk Prof. Aihud Pevsner said that he had intended to present new 3 SD evidence for the Kappa, but had changed his mind.” Kappa slowly disappeared.

  4. Efficient Use of Energy, a Physicist’s PerspectiveSeptember 25, 2006 Arthur H. Rosenfeld, Commissioner California Energy Commission (916) 654-4930 ARosenfe@Energy.State.CA.US http://www.energy.ca.gov/commission/commissioners/rosenfeld.html

  5. How Much of The Savings Come from Efficiency? • Easiest to tease out is cars • In the early 1970s, only 14 miles per gallons, now 21 mpg • If still at 14 mpg, we’d consume 75 billion gallons more and pay $225 Billion more at 2006 prices • But we still pay $450 Billion per year • If California wins the “Schwarzenegger-Pavley” suit, and it is implemented nationwide, we’ll save another $150 Billion per year • Commercial Aviation improvements save another $50 Billion per year • Appliances and Buildings are more complex • We must sort out true efficiency gains vs. structural changes (from smokestack to service economy).

  6. How Much of The Savings Come from Efficiency (cont’d)? • Some examples of estimated savings in 2006 based on 1974 efficiencies minus 2006 efficiencies • Beginning in 2007 in California, reduction of “vampire” or stand-by losses • This will save $10 Billion when finally implemented, nation-wide • Out of a total $700 Billion, a crude summary is that 1/3 is structural, 1/3 is transportation, and 1/3 is buildings and industry.

  7. A supporting analysis on the topic of efficiencyfrom Vice-President Dick Cheney • “Had energy use kept pace with economic growth, the nation would have consumed 171 quadrillion British thermal units (Btus) last year instead of 99 quadrillion Btus” • “About a third to a half of these savings resulted from shifts in the economy. The other half to two-thirds resulted from greater energy efficiency” Source: National Energy Policy: Report of the National Energy Policy Development Group, Dick Cheney, et. al., page 1-4, May 2001 Cheney could have noted that 72 quads/year saved in the US alone, would fuel one Billion cars, compared to a world car count of only 600 Million

  18. Illuminating Space vs. the Street

  19. Cool Colors Reflect Invisible Near-Infrared Sunlight

  20. Heat Mirror Windows – Steve Selkowitz, LBNL • Low Emissivity films are required by building standards world-wide. They reflect far infrared radiation. Retain indoor heat in winter, reflect outdoor heat in summer. They double the R-value of double glazing, and the inside pane is warm to the touch – more comfortable • Before low-E, windows were 30% of the heat load of a home – now 15%. • During a Montana winter, a north-facing low-E window, facing a snowy sunlit slope, is a net energy gainer. • “Selective film are required for Commercial Buildings in California. They reflect far- and near-infrared radiation, and halve the solar gain though windows; including car windshields in BMW’s etc. • Modern windows save ~1 Mbod of oil equivalent, = Alaskan oil.

  21. Temperature Rise of Various Materials in SunlightDr. Hashem Akbari, LBL Heat Island Group 50 40 30 20 10 0 Galvanized Steel Black Paint IR-Refl. Black White Cement Coat.

  22. Temperature Trends in Downtown Los Angeles

  23. Potential Savings in LA • Savings for Los Angeles • Direct, $200M/year • Indirect, $140M/year • Smog, $360M/year • Estimate of national savings: $10B/year

  24. Cool Colors Reflect Invisible Near-Infrared Sunlight

  25. From Cool Color Roofs to Cool Color Cars • Toyota experiment (surface temperature 10K cooler) • Ford is also working on the technology

  26. Cool Colors Reflect Invisible Near-Infrared Sunlight

  27. UV Water Purification

  28. Ultra Violet Water Purification for Villages in Developing World Ashok Gadgil at LBNL points out if UV treatment replaces boiling 10 tons of water per day, each system avoids 4 tons of CO2 per day. An American car emits only 4 tons of CO2 per YEAR. • Meet / exceed WHO and US EPA criteria • Energy efficient: 60 watts disinfects 1 ton / hour • Low cost: 4 cents disinfects a ton of water • Reliable, Mature components • Can treat un-pressurized water • Rapid throughput: 12 seconds • Low maintenance: once every three months • >100 units now operating in India and Phillipines • http://www.waterhealth.com/

  29. Dr. Ashok Gadgil’s Darfur Cookstove Project In Nov.-Dec. 2005, he visited Darfur camps, and showed that with a $10 metal stove, and training to use it, only half the fuelwood is needed. The stove saves fuelwood worth $160 annually for a refugee family Since that time, Ashok Gadgil has improved stove efficiency by another factor of two http://www.osti.gov/bridge/servlets/purl/878538-hMpqN3/878538.PDF

  30. LEDs Powered with Photovoltaics • Evan Mills at LBNL points out the following: If 1 billion people could replace kerosene lamps with LEDs, emissions would drop by the equivalent of 1.3 million barrels of petroleum per day • http://eetd.lbl.gov/emills/PUBS/Fuel_Based_Lighting.html
