Cars of Tomorrow
Mechanical and electrical
engineers at
DaimlerChrysler, General
Motors and BMW have jointly
developed a hybrid-vehicle
technology that shuts the
internal combustion engine
off when the vehicle stops.

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

Diesel Guzzler - Money Saver
Engineers made aerodynamic
alterations to the design of
truck trailers in order to
reduce drag and improve fuel
economy. The design uses
pressurized air active flow
control techniques along

'Cool' Car
Engineers at a national lab
have shown that small fans
embedded in car seats could
help cool passengers down --
saving up to 7 percent of
the 30 to 40 gallons of
gasoline per year an average
driver consumes for powering

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 -
Metallurgical Engineers Introduce Stronger, Lighter Steel
New steel technologies are offering better looks, performance and protection for cars. To make new steel alloys, metallurgical engineers are mixing different kinds of metals like nickel, with iron ... > more -
Computer Scientists Investigate Traffic Lights To Improve Fuel Economy
Using a mathematical model, transportation engineers can design optimum traffic light timing patterns for the fewest stops and driving delays. Improving traffic flow would decrease fuel consumption. ... > more -
Mechanical Engineers' Material Enhances Car Brakes
A fiber-reinforced ceramic, traditionally used in jets, has now been made into brakes for cars. The fibers strengthen the material and help keep it from ... > more -
Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
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 -
Acoustical Engineers Find Simple Way to Reduce Airplane Noise.
A new landing procedure keeps airplanes higher until they are much closer to the airport. The new procedure, called continuous descent approach, promises to save fuel money while cutting noise levels ... > more -
Engineers Use Mine Roof Simulator To Increase Mine Safety
Industrial hygienists, applying geology and engineering, can test mine support systems with the only mine roof simulator of its kind. Using up to 3 million pounds of vertical force and 1.6 million ... > more -
Automotive Engineers Bend New Materials into Futuristic Shapes
New materials for car bodies may soon transform the auto industry. Auto engineers can mold these carbon-fiber-reinforced plastics into virtually any shape. The materials are both strong and light -- ... > more -
Roboticists Create Rover To Move And Drill On The Moon
Engineers and robiticists created a robot to explore the moon. Running on the same amount of power as a 100-watt light bulb the rover uses heat from radiation to support its sensors, movement, and ... > more
