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 email@example.com.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
