Algae as a High-Temperature Hydrogen Source

A team of researchers from the University of Tennessee, Knoxville and Oak Ridge National Laboratory have found that the inner machinery of photosynthesis can be isolated from certain algae and, when coupled with a platinum catalyst, is able to produce a steady supply of hydrogen when exposed to light.

Detecting Airborne Mercury by Use of Polymer/Carbon Films

NASA's Jet Propulsion Laboratory has introduced another method for detecting airborne elemental mercury. When films made of certain polymer/carbon composites are exposed to air containing mercury vapor, their electrical resistances decrease by measurable amounts. The films can be operated and regenerated at mild temperatures.

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.

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.
