Interestingly, the first person he called was Joel Engel, his chief rival at AT&T’s Bell Labs, to tell him he was calling on a portable phone.

The original phone weighed a gargantuan 30 ounces, and was referred to as the “Brick.”

With nearly four decades of success in the telecommunications industry, Cooper’s guiding philosophy is to look to its bright future: It’s very exciting to be a part of a movement toward making broadband available to people with the same freedom to be anywhere that they have for voice communications today. People rely heavily on the Internet for their work, entertainment, and communication, but they need to be unleashed.

ng. Common storage media are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat exchanger equipped boreholes.

he heat pump is added-in because the temperature of the storage gradually increase during the cooling season, thereby declining in effectiveness. Free cooling and hybrid systems are mature

The basic concept behind air conditioning is said to have been applied in ancient Egypt, where reeds were hung in windows and were moistened with trickling water. The evaporation of water cooled the air blowing through the window, though this process also made the air more humid (also beneficial in a dry desert climate). In Ancient Rome, water from aqueducts was circulated through the walls of certain houses to cool them. Other techniques in medieval Persia involved the use of cisterns and wind towers to cool buildings during the hot season. Modern air conditioning emerged from advances in chemistry during the 19th century, and the first large-scale electrical air conditioning was invented and used in 1902 by Willis Haviland Carrier. The introduction of residential air conditioning in the 1920s helped enable the great migration to the Sun Belt in the US.
