There are about three-and-a-half miles of tunnels extending from the Blackstone power station along Memorial Drive and north to the Law School and through the Weeks Memorial foot bridge to the Business School...
...steam. When the water vapor contracts into a more dense state--from gas to liquid--it gives off energy in the form of heat. Once the steam condenses to water after it has served its heating purpose, it is sent back to the plant through the same system of underground lines and tunnels...
...same time, because the plant is not located directly on campus, the pipes lose some heat as the steam travels through the underground system. Engineers must also worry about the thermal expansion of underground pipes through junctions. "In 300 feet, [the pipes] may expand six to nine inches when they go from room temperature to steam at 400 degrees Fahrenheit," says Hawkes...
Unfortunately, "the chilled water plant is primarily not used for dormitories," he says. The cooling system is used mainly for libraries, laboratories and classrooms. In a similar method to steam distribution, the chilled water is produced at the plant at 42 to 44 degrees Fahrenheit and then pumped underground to about 65 buildings...

The son of heralded underground director Robert Downey (Putney Swope), he got small movie roles until a season-long stint on Saturday Night Live served as a springboard into "brat-pack" films in the mid-'80s.
