EPRI-developed PV cells power world-record solar car. (Electric Power Research Institute; photovoltaic)
March 1, 1994... The World Solar Challenge race across Australia for cars powered exclusively by photovoltaic (PV) cells was won in November 1993 by a vehicle using cells developed with EPRI and U.S. Department of Energy funding. The car was built by Honda R&D...

Ultraviolet light - an answer to tuberculosis?.
March 1, 1994... For half a century the health care industry has sporadically relied on ultraviolet (UV) light to kill bacteria. Now some members of the medical community are advocating the widespread use of this technique to control tuberculosis, which is making...

Solid futures in fuel cells. (solid-oxide fuel cells) (Cover Story)
March 1, 1994... THE STORY IN BRIEF SOLID-OXIDE FUEL CELLS, WHICH FEATURE SOLID RATHER THAN LIQUID ELECTROLYTES, REPRESENT THE NEXT BIG OPPORTUNITY IN FUEL CELL DEVELOPMENT. FREED FROM THE HANDLING DIFFICULTIES OF CORROSIVE LIQUIDS, THESE SOLID-STATE CELLS...

Innovations underground. (Georgia Power Company installs underground transmission lines)
March 1, 1994... THE STORY IN BRIEF A simple promise to bury an overhead transmission line turned into a big problem for Georgia Power Company when Native Americans pointed out that sacred burial grounds were located along the right-of-way. Complex geology...

Smart thermostats for comfort and conservation. (electronic line-voltage thermostats)
March 1, 1994... Electric resistance heaters are often the lowest-first-cost choice for heating new residences. Moreover, they can save energy by facilitating zoned heating, in which unoccupied rooms are maintained at a lower temperature. The problem with such...

High-speed rail heading down the track. (high-speed rail and magnetic levitation systems)(includes related article)
March 1, 1994... THE STORY IN BRIEF Heightened environmental awareness, increasingly congested airports and freeways, and advances in passenger transportation technologies used in other countries are prompting many regional government agencies to rethink...

New research benefits small businesses. (electric utilities help small businesses with energy use decisions)
March 1, 1994... Traditionally, the needs of small-business customers were not always high on the agenda of electric utilities. After all, many problems of this market segment require close and specialized attention that can take significant time away from larger...

Population studies may help define risk from arsenic.
March 1, 1994... In an effort to better define the health risk posed by exposure to arsenic, EPRI recently undertook two observational studies of small populations that are likely to be exposed to relatively high levels of the carcinogen. Present in trace amounts...
