Feather Fibers Fluff Up Hydrogen Storage Capacity

Scientists have developed a new hydrogen storage method - carbonized chicken feather fibers - that can hold vast amounts of hydrogen, and do it at a far lower cost than other hydrogen storage systems. The research could help overcome some of the hurdles to using hydrogen fuel in cars, trucks, and other machinery.

Sensing Method Checks Refrigerant Levels, Saves Energy

A new “virtual refrigerant charge sensor" saves energy and servicing costs by indicating when air conditioners are low on refrigerant, preventing the units from working overtime. Engineers at Purdue University developed the sensing technique, which is particularly practical for automotive air conditioners.

Fuel-Cell Power Systems Incorporating Mg-Based H2 Generators

Two hydrogen generators based on reactions involving magnesium and steam have been proposed at NASA’s Jet Propulsion Laboratory as means for generating fuel (hydrogen gas) for motor vehicles. The generators would make it unnecessary to rely on expensive, heavy, bulky, or unsafe hydrogen storage systems previously developed.

A Step Toward Producing Plastic from Biomass

Researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it can be effectively industrialized, could allow many of today’s petrochemical products, including plastics, to instead be made from biomass.

NASA Energy Concept Could Harness the Power of Ocean Waves

NASA Jet Propulsion Laboratory (JPL) researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable energy produced from the motion of the ocean and rivers could potentially meet an important part of the world’s demand for electricity.

Designing the First Fully Sustainable Block in the U.S.

In the near future, a crumbling parking lot in downtown Dallas, Texas will be the location of the first fully sustainable, urban square block in the United States. Re:Vision Dallas is the sixth competition in a series from the San Francisco, California-based organization, Urban Re:Vision – a group of people focused on changing the urban landscape by re-imagining the components which make up a city block.
