1 1 Annual Reviews of Nuclear Science 25, 555, 1975 THE PARTICLE DATA GROUP: GROWTH & OPERATIONS. 18 Years of Particle Physics Arthur H. Rosenfeld, Department of Physics and LBL, UCBerkeley.

2 2 u1957. Gell-Mann and Rosenfeld. Ann. Rev. Nucl. Sci. and UCRL 8030 by Barkas and Rosenfeld. 1958 1 st update of 8030, with original wallet card. Then no revisions until 1961. 1961. Several new baryon and meson resonances 1963 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. 1964.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. 1967 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 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 observed yearly 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 Perspective September 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

7 7 How Much of The Savings Come from Efficiency? uEasiest 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 uCommercial Aviation improvements save another $50 Billion per year uAppliances and Buildings are more complex –We must sort out true efficiency gains vs. structural changes (from smokestack to service economy).

8 8 How Much of The Savings Come from Efficiency (cont’d)? uSome examples of estimated savings in 2006 based on 1974 efficiencies minus 2006 efficiencies uBeginning in 2007 in California, reduction of “vampire” or stand-by losses –This will save $10 Billion when finally implemented, nation-wide uOut 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.

9 9 A supporting analysis on the topic of efficiency from Vice-President Dick Cheney u“ 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” u“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

30 30 Heat Mirror Windows – Steve Selkowitz, LBNL uLow 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 uBefore low-E, windows were 30% of the heat load of a home – now 15%. uDuring a Montana winter, a north-facing low-E window, facing a snowy sunlit slope, is a net energy gainer. u“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. uModern windows save ~1 Mbod of oil equivalent, = Alaskan oil.

38 38 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. uMeet / exceed WHO and US EPA criteria uEnergy efficient: 60 watts disinfects 1 ton / hour uLow cost: 4 cents disinfects a ton of water uReliable, Mature components uCan treat un-pressurized water uRapid throughput: 12 seconds uLow maintenance: once every three months u>100 units now operating in India and Phillipines uhttp://www.waterhealth.com/http://www.waterhealth.com/ Ultra Violet Water Purification for Villages in Developing World

39 39 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/pur l/878538-hMpqN3/878538.PDF Dr. Ashok Gadgil’s Darfur Cookstove Project
