First Major System in The United States
Cornell University's Lake Source Cooling System uses Cayuga Lake as a heat sink to operate the central chilled water system for its campus and to also provide cooling to the Ithaca City School District. The system has operated since the summer of 2000 and was built at a cost of $55–60 million. It cools a 14,500 ton (51 megawatt) load.
Lake water enters the system via a screened intake structure 10,400 feet (3,200 m) away in 250 feet (76 m) of water. The intake pipeline is 63-inch (1.6 m) High Density Polyethylene (HDPE) that was deployed from the surface using a "controlled" sink process where water was pumped in at the shallow end and air was released at the other end. A series of stiffener rings and concrete collars keep the pipeline on the lake floor and protect it from mechanical forces. The outfall is 48-inch (1,200 mm) HDPE and is approximately 750 feet (230 m) long. The last 100 feet (30 m) of the outfall has 38 six-inch (152 mm) nozzles, about 1 foot (0.30 m) above the bottom of the lake floor in 14 feet (4.3 m) of water, pointed up at a 20 degree angle and pointed north only. This helps promote mixing of the return water into the receiving water. The water cools a heat-exchanger which is connected to a closed-loop campus chilled water distribution system linked to many buildings on the main campus.

“In a moment when criticism shows a singular dearth of direction every man has to be a law unto himself in matters of theatre, writing, and painting. While the American Mercury and the new Ford continue to spread a thin varnish of Ritz over the whole United States there is a certain virtue in being unfashionable.”
—John Dos Passos (1896–1970)
“The major men
That is different. They are characters beyond
Reality, composed thereof. They are
The fictive man created out of men.
They are men but artificial men.”
—Wallace Stevens (1879–1955)
“Society cannot share a common communication system so long as it is split into warring factions.”
—Bertolt Brecht (1898–1956)
“... when we shall have our amendment to the Constitution of the United States, everyone will think it was always so, just exactly as many young people believe that all the privileges, all the freedom, all the enjoyments which woman now possesses were always hers. They have no idea of how every single inch of ground that she stands upon to-day has been gained by the hard work of some little handful of women of the past.”
—Susan B. Anthony (1820–1906)
“I think those Southern writers [William Faulkner, Carson McCullers] have analyzed very carefully the buildup in the South of a special consciousness brought about by the self- condemnation resulting from slavery, the humiliation following the War Between the States and the hope, sometimes expressed timidly, for redemption.”
—Jimmy Carter (James Earl Carter, Jr.)
