New Pathway to Forming Hydrogen Storage Compounds

Scientists at the Carnegie Institution for Science have found that high pressure can be used to make a unique hydrogen-storage material. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen under pressure to form a previously unknown solid with unusual bonding chemistry.

Smartphone Application Sheds Light on Power Consumption

PowerTutor, a new application developed by researchers at the University of Michigan for the Android smartphone, shows users how much power their applications are consuming. PowerTutor shows in real time how four different phone components use power: the screen, the network interface, the processor, and the GPS receiver.

Using Aerospace Approach, Engineers Design Wave Energy System

Aerospace engineers from the U.S. Air Force Academy are applying the principles that keep airplanes aloft to create a new wave energy system that is durable, efficient, and can be placed anywhere in the ocean - regardless of depth. While still in early design stages, computer and scale-model tests of the system suggest higher efficiencies than wind turbines.

NASA's Algae Bioreactor Licensed to Algae Systems, LLC

Earlier this year, NASA introduced an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. The NASA bioreactor is an Offshore Membrane Enclosure for Growing Algae (OMEGA), which won't compete with agriculture for land, fertilizer, or freshwater.

Hitting the Theoretical Roof of Converting Waste Heat to Electricity

The need to get rid of excess heat creates a major source of inefficiency in everything from computer processor chips to car engines. According to Peter Hagelstein, an associate professor of Electrical Engineering at MIT, existing solid-state devices to convert heat into electricity are not very efficient. Experimenting with thermal diodes, an MIT team has come closer to the theoretical limitations for the efficiency of such a conversion.

Microscopic Bubbles Clean Oil from Polluted Water

Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. A University of Utah engineer has developed an inexpensive method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas - creating tiny bubbles that attack the oil so it can be removed by sand filters.
