Here Come The 123s List Price: $18.98 Sale Price: $8.35 |
|
They Might Be Giants are like the handful of best-selling authors who also happen to be doctors or astrophysicists: They do two things so well--in their case kids' music and grown-up music--that it seems a little unfair, like the talent scale has been tipped too hard in their favor. Like Here Come the 123s, the follow-up to 2005's Here Come the ABCs, and TMBG's third kids' record. Here the Johns--Linnell and Flansburgh--are up to their usual smart shenanigans: In "Seven," a bunch of skinny numerals crash a stranger’s living room before settling in for some cake, and in "Nine Bowls of Soup" an ichthyosaur is so enamored of soup he works out a way to balance a multitude of bowls on his scaly body. The brilliance isn’t limited to the lyrics. The Johns know a thing or 1-2-3 about crafting seriously jammable music. Highights include “High Five,” a flippy, freewheeling dab of disco, and “One Everything,” a juiced-up, jangly rocker with a message for listeners ages 3 to 93: an untidy room actually is an insult to the omniverse. --Tammy La Gorce Grammy Winning, Platinum selling Artists They Might Be Giants formed as a duo in 1982.\n\nFollowing a successful decade, in the late 90s the band began expanding their horizons into television, movies, and the internet, notably contributing the opening th |

Alison Krauss & Union Station - Live List Price: $19.98 Sale Price: $8.37 |
|
This two-CD, 25-song set, recorded in Louisville on two nights in the spring of 2002, finds bluegrass's most celebrated crossover band at the top of its game. Krauss's warm, feathery vocals, capable of conveying complex emotions in a single note, appear more full-bodied than in studio recordings, yet lose none of their sensual appeal or dramatic tension. She's perfect, for example, as the melancholy temptress on "Let Me Touch You for Awhile," coming across as both savior and seductress, while Jerry Douglas's Dobro echoes the searing strains of passion and pain. With banjoist-guitarist Ron Block, bassist Barry Bales, and guest drummer Larry Atamanuik anchoring the rhythm, the ensemble deftly blends bluegrass with jazz, rock, and folk, combining lightning speed (though rushing through "Forget About It") with sophisticated chops, tangible emotion, and thrilling vocal blends. The crowd, more spellbound with every note, doesn't even breathe on "Ghost in This House" and nearly tears the place down on Dan Tyminski's voice-of-George Clooney showcase, "I Am a Man of Constant Sorrow." But who could blame them? It's only one highlight on an album of uncommon artistry, a moving testament to how good live music can be in the hands of world-class players. --Alanna Nash Two CD LIVE set in a slimline double jewelbox as Alison Krauss + Union Station. Light scuffs on discs will not affect play. |

Energy Compensation Using Solar Power Stations in Space
1. INTRODUCTION: FUTURE ENERGY NEEDS
Mankind has recently enhanced its living standard and its population in an explosive way. In fact, the human population quadrupled and primary power consumption increased 16-fold during the 20th century [1]. The consumption of energy, food, and material resources is predicted to increase 2.5 fold in the coming 50 years. As a result of our efforts for better life, we have come to face, in this 21st century, serious global issues threatening our safe life or even our existence itself on our mother planet earth. These are issues such as global warming, environmental degradation, declining nutrition on land and sea from rising CO2, and rapid decrease of fossil reservoir. Since the living standard and the population of developing countries are increasing continuously, the demand of energy will be several times larger than that of today's requirement by the time of the half way of this century.
In 2000, the world had 6.1 billion human inhabitants. This number could rise to more
than 9 billions in the next 50 years as shown in Fig.-1. This future population increase is mostly due to very rapid increase in less developed countries although the number in more developed countries will be almost constant (about 1 billion) or rather decrease [2].
Fig.-1 World Population Prospects [2]
The explosive increase in the human population inevitably requires an exponential increase in the consumption of energy, food, and material resources. One primary power source at present comes from fossil fuels such as oil, coal and natural gas. However, the fossil fuels have two serious factors which prevent them from being used for a long term as primary power source. One is their limited amount that does not last long if used with the same or higher pace than that of today (Fig.-2). The other is their negative feature of emitting carbon dioxide, one of the green house gases, which causes the global warming.
Fig.- 2 Pattern of Global Energy Dependence [3]
Fig.-3 Atmospheric carbon dioxide monthly mean mixing ratios. Data prior to May 1974 are from the Scripps Institution of Oceanography (SIO, blue), date since May 1974 are from the National Oceanic and Atmospheric Administration (NOAA, red). A long term trend curve is fitted to the monthly mean values [4]
Atmospheric CO2 has increased from 275 parts per million (ppm) before the industrial era begun to 379 ppm in March 2004 as shown in Fig.-3. Some scientists suggest that it will pass 550 ppm this century. Climate models and paleoclimate data indicate that 550 ppm, if sustained, could eventually produce global warming comparable in magnitude but opposite in sign to the global cooling of the last Ice Age [5].
Global energy demand continues to grow along with worldwide concerns over fossil fuel pollution, the safety of nuclear power and waste, and the impact of carbon-burning fuels on global warming. As a result sustainable energy sources like solar, wind, hydropower, biomass, geothermal, hydrogen, ocean thermal, tidal power etc are drawing prime attention, out of which solar power is the most promising one. Terrestrial solar power has too many limitations like atmospheric attenuation, daily and seasonal variation, and affects by climate conditions etc. To overcome these limitations concept of Solar Power from Space is getting momentum, which was first proposed by Czech-American engineer Peter Glaser as a solution to the oil crises of the 1970s [6]. Solar Power from Space is a proposed concept to place a gigantic solar power station in space orbiting around the earth that uses microwave power transmission to beam solar power to a very large antenna on earth where it can be used in place of conventional power sources.
2. SPACE SOLAR POWER (SSP) vs TERRESTRIAL SOLAR POWER (TSP)Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
The SSP concept arose because space has several major advantages over earth for the collection of solar power. Space is free from day-night cycle, atmosphere, clouds, dust, rain, fog and other climatic changes, so it would receive 30% more intense and at least eight times more sunlight than that of at ground constantly and continuously unaffected by the weather. In geosynchronous orbit it would receive sunlight almost 24 hours a day hence avoiding the expensive storage facilities necessary for earth-based solar power systems. Since earth’s axis is tilted, it would be in earth’s shadow only for 70 minutes maximum at late night when power demands are at their lowest, during 42 days near the equinoxes [7] as shown in Fig.-5.
Fig.-5 Daily duration of eclipses as a function of the date [7]
3. SSP: SYSTEM DESIGN AND TECHNOLOGIES
The SSP system is composed of a space segment and a ground power receiving site (Fig.-6). Space segment consists of mainly three parts; solar energy collector to convert the solar energy into DC (Direct Current) electricity, DC-to-microwave converter, and large antenna array to beam down the microwave power to the ground. Ground power receiving site uses a device called rectenna (rectifying antenna) to receive and rectify the microwave power beam. The rectenna system converts the microwave power back to DC power which is then converted to conventional AC (Alternating Current), and is connected to existing electric power networks.
Assuming typical values for efficiencies like 15% for solar panels to convert solar energy into DC, 70% conversion rate in the space segment from DC to microwave, 90% beam (power) collection efficiency, and 80% conversion rate for rectenna from microwave to DC in ground segment, the estimated over-all efficiency is approximately 7.5 %. With such efficiency a SSP space segment would be of size of about 50 km2 (5 km x 10 km) to generate 5 GW DC power on earth (Fig.-6).
Fig.-6 : Reference Model: 5 GW GEO based Space Solar Power Station Designed by US Department of Energy (DOE) and NASA in 1979 [8]
3.1 -SOLAR CELL: EFFICIENT STRUCTURES
In the very near future, breakthroughs in nanotechnologies promise significant increase in solar cell efficiencies from current 15% values to over 50% levels. That might decrease required size of space segment by about 3 fold. Author proposes Metal-Metal junction cavity solar cell which theoretically promises to increase solar-electric conversion efficiency many folds.
A cavity of metal m2 (work function W2) with thin polish of metal m1 (work function W1, W1 <W2 , Fig.-7) on inner surface, with a pin hole is kept at the focus of the solar concentrator coinciding the pinhole and focus. Pinhole is covered with transparent glass to protect inner polish of cavity from atmospheric reaction. Such cavity behaves as metal-metal junction solar cell (termed as M-M cavity solar cell) with various features (described below) leading to enhancement of solar-electric conversion efficiency.
· The major loss in usual structures is the reflection loss (about 30%) but in M-M cavity solar cell once ray enters in cavity, undergoes multiple inner reflecti
About the Author
design a telescope to meet their needs. could you test your design by observing stars from earth?
astronaunts observing from a space station need a telescope with a light gathering power 15000 times that of the human eye, capable of resolving detail as small as second of arc and having a magnifying power of 250. design a telescope to meet their needs. could you test your design by observing stars from earth?
To gather 15,000 times as much light as a human eye, the aperture must have 15,000 times the area of a human eye. In the dark, a healthy human can have a pupil diameter of 8mm. Since A=pi*r^2, you can calculate the light gathering area of the pupil, then multiply that up by 15,000.
The formula for diffraction-limited resolution is:
angular resolution (radians)= 0.1384/D, where
D = telescope diameter in m
And the conversion:
1 arcsecond = 4.84813681 × 10-6 radians
So either the factor of 15,000, or the resolution requirement, will place a constraint on the minimum diameter of your design.
In terms of magnifying power,
magnification = focal length of objective / focal length of eyepice.
So this ratio must be 250.
Finally, Hamal, also known as alpha Cassiopeiae, is 6.88 milliarcseconds in diameter and appears to be large due to its proximity. Obviously, 6.88 milliarcseconds is much smaller than one arcsecond (i.e., one thousand milliarcseconds), so no, the resolution of a scope such as you describe could not be tested by viewing stars. Especially when considering atmospheric turbulence that blurs seeing.
