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.

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.

"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.

Silver Nanoparticles Give Polymer Solar Cells A Boost

Researchers at Ohio State University, led by professor Paul Berger, are experimenting with polymer semiconductors that absorb the sun’s energy and generate electricity - with the goal of lighter, cheaper, and more-flexible solar cells. The team has discovered that adding tiny bits of silver to the plastic boosts the material's electrical current generation.
