Bringing Sunlight Inside
Photovoltaic panels have a
new design: concentric
circles that focus the sun's
rays on miniaturized
modules. Having the panels
automatically sense sunlight
and turn towards it also

Wind Farms Impacting Weather
Wind farms may have an
impact on local weather
patterns. As environmental
engineers have discovered,
wind farm propellers create
a lot of turbulence in their
wake, mixing air up and down

Environmental Engineers Use Algae To Capture Carbon Dioxide
Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae. A team at Ohio University created a photo bioreactor that uses photosynthesis to grow algae, ... > more -
Engineers Create Exhibits on Achievements, Promise
Nanotechnology has already brought advances such as self-cleaning windows and energy-efficient LED lighting, and could soon deliver medical breakthroughs. To educate the public about nanotechnology's ... > more -
Engineer Designs More Efficient, Quieter Bus
An engineer has designed an electric bus that runs on battery power. Putting motors in each wheel makes a transmission and driveshaft unnecessary, and allows the bus to ride closer to the ground for ... > more -
Human-Factors Engineers Focus on User-Friendliness
Human-factors engineers -- whose training includes psychology -- specialize in testing products for usability, for example checking whether a copying machine's legs get in the way, or measuring how ... > more -
1,400 Students Showcase Inventions at Science and Engineering Fair
Some of the nation's most talented students converged on Phoenix on May 8-13 to show their inventions at the Intel International Science and Engineering Fair, the world's largest competition of its ... > more -
Engineers Design Sensor That Detects Leaky Pipes From The Inside
Engineers can now drop an acoustic sensor into working water pipes and detect leaks, as small as one quart per hour. The sounds created by holes are pinpointed, leading to earlier detection, patch ... > more -
Electrical Engineers Develop Microplasma Device to Detect Toxins
Electrical engineers have developed a new, portable lab that identifies chemicals by their unique color signatures. It is the first such device to be portable, allowing scientists to recognize ... > more -
Civil Engineers Learn from Dutch Flood Barrier System
A group of U.S. civil engineers and city officials went on a recent trip to the Netherlands -- a country much of which is below sea level -- to study the country's storm surge barrier system. The ... > more -
