The Power Plant in your Basement
In the past, stationary fuel cells were megawatt behemoths, designed for the electric utilities. Now they are being shrunk for homes and other modest applications
Features
The Mystery of Nucleon Spin
A new generation of experiments promises to pin down more of the still uncertain internal structure of protons and neutrons
The Future of Fuel Cells
The obstacles to building practical fuel cells are numerous, but continued innovation and skillful engineering could make them competitive
The Electrochemical Engine for Vehicles
Fuel cells can power cleaner buses and cars, but key engineering and economic obstacles will delay widespread adoption of the technology
Replacing the Battery in Portable Electronics
Batteries are cumbersome and expensive. Miniature fuel cells could supplant them in cellular phones, laptop computers, camcorders and other consumer products
Looking Back at Apollo
On the 30th anniversary of the first manned lunar landing, digital reproductions of the Apollo photographs show the moon as the astronauts saw it
Life's Far-Flung Raw Materials
Life may owe its start to complex organic molecules manufactured in the icy heart of an interstellar cloud
