128 Landscape Architect and Specifier News The city of Knoxville, Tenn., has spent $125,000 for a 36-page Urban Land Institute report on the future of downtown Knoxville. The study involved a weeklong visit by a panel of urban planners, architects and developers. Public input on the report is up next. City officials directed the ULI to study five areas of the city. The first major recommendations in the report is for the city to "walk away from the aging Civic Coliseum," which loses around $1 million each year and has a growing list of maintenance needs, and direct money instead toward redevelop the Mountain View neighborhood around the coliseum into a mixed-residential neighborhood. The second significant recommendation is to "activate the edge of World's Fair Park," which the report considers an important community asset, by redesigning or rebuilding the Knoxville Convention and Exhibition Center, and including room for a cultural attraction, i.e., a theatre or museum. The Knoxville Museum of Art lies just north of the park. Knoxville's Sunsphere was constructed for the 1982 World's Fair. The Sunsphere's observation deck on the fourth floor reopened to the public on May 5, 2014. This iconic beacon and the Tennessee Amphitheater are the only structures remaining from the fair in the aptly named World's Fair Park. The Urban Land Institute report recommends the city "activate the edge of World's Fair Park," plus redevelop the area around the Knoxville Civic Auditorium and Coliseum into a mixed-residential neighborhood.

Lucid energy says the hydrodynamic turbines have been lab tested to maximize efficiency and power generation, while limiting the onset of cavitation (bubbles in liquid, i.e., voids). As velocities increase, power production increases. due to the lift-based design of the pipe turbines, the system generates power across a wide range of velocities. IMAge: LUCId energy Pipe Power The Greeks harnessed the power of moving water with the water wheel in the third century B.C. to irrigate and supply power. It took two millennia, however, before hydraulic machines were described (French engineer Bernard Forest de BĂ©lidorin, mid-1770s), and it was not until the late 19th century that the electrical generator was developed. Note: The Association for Industrial Archaeology reports the first realization of hydroelectric power came in 1878 when Englishman William Armstrong lit a single arc lamp with it. Fast forward to today. Portland-based Lucid Energy has come up with the idea to install small turbines into water pipes, which send the energy of the flowing water to a power generator. Gregg Semler, CEO of Lucid Energy, reports the company has a project in Riverside, California that's making use of the water pipe power to light streetlights. Lucid has recently installed the power-generating pipes in Portland, where they are powering public spaces throughout the city. Sensors in the pipe reportedly can even monitor if the water is safe to drink. I n f o r m a t i o n R e q u e s t # 7 2 3
