Engineers Envision Cheaper Algae Oil Production

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing systematic production methods that could lower the costs of algae oil production. They plan to grow algae in the ocean on very large, supporting platforms.

Robotic Fish Can Swim, Maneuver, and Monitor Water Quality

Michigan State University researchers are developing robots that use advanced materials to swim like fish and gather precise data on aquatic conditions. The robotic fish will carry sensors recording things like temperature, dissolved oxygen, pollutants, and harmful algae.

Will Microsoft’s Windows 7 succeed?

This week’s question concerns Microsoft’s Windows 7 operating system. Microsoft released the new operating system last week to generally more favorable reviews than its bug-laden, slow-selling Vista predecessor. While Microsoft claims Windows 7 resolves many of Vista’s flaws, skeptics contend the software giant faces stiffening competition from Apple and open-source software based on Linux, as well as reluctance from users of older Windows versions to upgrade. What do you think? Will Microsoft’s Windows 7 succeed? Yes or no?

Cryogenic Chamber for Servo-Hydraulic Materials Testing

A compact cryogenic test chamber can be cooled to approximately 5 to 6 Kelvin for materials testing. The system includes a temperature controller and multiple sensors to measure specimen temperature at different locations. The testing chamber provides a fast and easy method to perform materials testing at lower than liquid nitrogen temperature (77 K). The advantage of this chamber is that lower than 77 K temperatures are achievable, and the temperature can be controlled and stabilized during a test.
