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?

Harvesting Energy from Regular, Day-to-Day Motions

Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

Permeable Pavement and Reducing Water Runoff

Paved parking lots and driveways often create an easy pathway for pollutants to reach underground water sources and change the natural flow of water back into the ground. Today, EPA announced a study that will investigate ways to reduce pollution that can run off paved surfaces and improve how water filters back into the ground.

Should net neutrality rules be imposed on broadband service providers?

This week’s question concerns net neutrality. The Federal Communications Commission last week began drafting legislation that would prevent phone and cable companies from abusing their control over the broadband access market, by prohibiting them from censoring certain kinds of Internet traffic. Proponents say the rules are needed to ensure that broadband subscribers can access all legal Web sites and services and prevent service providers from engaging in anti-competitive practices. Opponents argue such regulations would make it more difficult for broadband providers to manage as well as expand their networks. What do you think? Should net neutrality rules be imposed on broadband service providers? Yes or no?

"Earth Binoculars" Sense Disasters From Space

New Tel Aviv University technology combines sophisticated sensors in orbit with sensors on the ground and in the air to create a “Hyperspectral Remote Sensor” (HRS). HRS can give advance warnings about water contamination after a forest fire, or swiftly alert authorities of a pollution spill.
