Wind Turbine Blades Destined for the Afterlife

Cars That Think

This group of wind-turbine fan blades, fresh from Siemens Gamesa’s new RecycleBlade manufacturing process at England’s largest such factory, await shipment to the various points around the globe where they will serve 20- to 30-year stints generating electricity at wind farms before they’re recalled and reincarnated. What’s Next?

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is. How fast can you ramp your power plants up and down to handle the variability from wind and solar?

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

This article, by researchers at PARC and the University of Washington, is one possible answer. This time around, though, the emphasis is on “green hydrogen”—that is, hydrogen produced using clean energy such as solar or wind power. Most of the world’s hydrogen comes from deeply polluting methods.

Study finds paved surfaces in Houston worsen air quality

Green Car Congress

New research by a team from the US, China and Japan focusing on the Houston, Texas area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.

Who Really Invented the Rechargeable Lithium-Ion Battery?

Cars That Think

Oxford takes the handoff In 1976, John Goodenough [left] joined the University of Oxford, where he headed development of the first lithium cobalt oxide cathode. The University of Texas at Austin It was the first of many false starts for the rechargeable lithium battery. But he found no takers.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). Bottom: C2CNT Cement wind plant: The full oxy-fuel configuration is shown.
