The dependence of the thickness of solar sail on temperature and on wavelength of the electromagnetic spectrum of solar radiation is investigated.
In 1999, a group of mechanical engineers created a computer model to analyze the ability of the sail to regulate body temperature during different seasons, and concluded that the sail was beneficial for capturing and releasing heat at all times in the year.
The rest of the year, they sail and ski in temperatures that the sea maintains not far below freezing.
Keith Gessen travels on the Nordic Odyssey, a cargo ship that, thanks to rising temperatures, can sail the Northeast Passage, from Russia to China.
Natural history goes to auction five or six times a year in America, and one Sunday last May a big sale took place in Chelsea,… Keith Gessen travels on the Nordic Odyssey, a cargo ship that, thanks to rising temperatures, can sail the Northeast Passage, from Russia to China.
I am sitting in a café in a Euro-Soviet city, drinking from a little pot of tea, looking at my computer, and wondering whether the… Keith Gessen travels on the Nordic Odyssey, a cargo ship that, thanks to rising temperatures, can sail the Northeast Passage, from Russia to China.
Schiff the pianist gave it controlled passion and effortless digitality -- only the first-movement cadenza fell short of its highest musical temperature -- and sailed through the breezy and difficult finale after a magical recitation of the crucial Intermezzo.
Even as news arrived of snow in San Francisco, the temperature in New York sailed into the 60's yesterday, causing cherry trees to blossom in Brooklyn and crocuses -- the traditional harbingers of spring -- to bloom in Central Park.
At an average high temperature of 77.5, this February sailed almost two degrees above the previous record set in 1954, according to a Times analysis.
The minimum foil thickness that provides the maximum reflectivity and absorption for a solar sail material is found and its dependence on temperature and on wavelength of the electromagnetic spectrum of solar radiation is investigated.
