Photovoltaic-Cell Technologies Joust for Position

Article Abstract:

Photovoltaic cells soon will be ready for widespread use as cell efficiencies improve to where modules can be a cheaper source of electricity than oil. Research has expanded in both international governments and in industry. The choice of technologies has been narrowed to single-crystal-silicon cells, polycrystalline thin films and amorphous silicon thin films. In addition to an aggressive five year United States Department of Energy research plan, Japan and Europe are heavily into photovoltaic research. Photographs show some operating photovoltaic modules around the world.

The Art and Science of Ergonomics

Article Abstract:

Airline engineers of today borrow their designs for displays and controls from space craft designers. Many advances found on the new Boeing 767 were based on space shuttle design. Improvements over older aircraft include digital electronics and microprocessors, CRT displays and digital readouts, laser gyroscopes, and greater visibility and room to move.

EPRI's First Decade

Article Abstract:

The Electric Power Research Institute (EPRI) has grown to 720 staff members with a budget of $310 million in only ten years. Utilities have requested that EPRI develop equipment to cut transmission losses, improve reliability, and avoid installing extra generating capacity. The organization and operation of EPRI is elucidated.
