In another move to protect the ozone layer, the Electric Power Research Institute (EPRI) and American Power Corp. (Boston) have formed an alliance to field test 3 kW fuel-cell systems for residential and commercial markets. The test will evaluate up to 25 "alpha series" prototype fuel cells to assess their technical and economic potential for services with power requirements in the 1-50 kW range. A typical residence uses 1-2 kW over a 24-hr period. The newer polymer electrolyte membrane (PEM) fuel-cell technology has advanced rapidly in the last couple of years, the team reports. American Power's Residential Power Generator, which uses natural gas, propane, or other hydrocarbon fuels as the power source, allows a home to operate either on or independent from a utility power grid. American Power is currently commercializing PEM cells that range from 1 kW up to several megawatts for niche markets. EPRI will lead a field evaluation and demonstration program and manage a users' group. Users will provide feedback on fuel-cell performance, reliability, and durability. EPRI is seeking sponsors to order up to 25 units for delivery in mid-1998. E-mail chopf@epri.com.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
