Biotreibstoffe bieten eine Perspektive den CO2-Abdruck der Luftfahrt zu senken sowie mögliche ungünstige Klimaeinflüsse von Partikelemissionen und Kondensstreifen zu reduzieren. Diesem weltweit aktuellen Forschungsthema widmen sich die US-amerikanische Luft- und Raumfahrtbehörde NASA und das Deutsche Zentrum für Luft- und Raumfahrt (DLR) sowie das kanadische National Research Council (NRC) bei gemeinsamen Flugversuchen vom 7. bis 16. Mai 2014 in Kalifornien. In typischen Reiseflughöhen werden die Emissionen eines Biotreibstoff-Kerosin-Gemisches sowie dessen Auswirkungen auf die Bildung und Eigenschaften von Kondensstreifen vermessen. Die von der NASA geleitete Flugkampagne umfasst mehr als einhundert beteiligte Wissenschaftler und Techniker. Vier Forschungsflugzeuge sind im Einsatz, darunter die Falcon 20-E des DLR. Ausgangsort ist das Armstrong Flight Research Center der NASA am Standort Palmdale/Kalifornien. (more…)

UD-Stanford team calculates maximum global energy potential from wind

Wind turbines could power half the world’s future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.

The researchers arrived at the determination by calculating the maximum theoretical potential of wind power worldwide, taking into account the effects that numerous wind turbines would have on surface temperatures, water vapor, atmospheric circulations and other climatic considerations.

“Wind power is very safe from the climate point of view,” said Cristina Archer, associate professor of geography and physical ocean science and engineering at UD. (more…)

WASHINGTON—Rocket exhaust could become a significant contributor to global climate change in coming decades, according to a new study. The research finds that soot emitted by rockets — not their carbon dioxide emissions — has the greater potential to contribute to global climate change in coming decades. (more…)
