Contrails and Climate Change

Dean Sigler Diesel Powerplants, Sustainable Aviation Leave a Comment

Contrails are the trails of condensed water vapor that follow an airplane at a high enough and cold enough altitude.  They became a visible presence in World War II and were part of newsreels of allied bombers hitting Germany and dog fights over the English countryside.  There was more than just an aesthetic side to the new, high clouds in the sky, though. Post-9/11 During the attacks on September 11, 2001, FAA controllers, “Did the only thing they could think of to try to control the situation: ordering every aircraft in U.S. airspace, about 4,000 of them, to land somewhere, anywhere, immediately.” “Canadian officials followed. Airports in Atlantic Canada quickly filled with thousands of bewildered people who had been flying west across the …

Capturing Carbon and Making Airplanes from It

Dean Sigler Electric Aircraft Materials, Solar Power, Sustainable Aviation Leave a Comment

Climate scientists have tracked the growing percentage of carbon dioxide (CO2) in the air, and noted a correlation between that rise and global warming.  Scientists from Michael Mann to Benjamin Santer have measured the changes in CO2 levels against climate change, with 97 out of 100 climate scientists accepting that human activities and rises in CO2 (and other greenhouse gases such as methane) are affecting our overall climate. Not to start an argument about this matter, this entry looks at a novel method of removing CO2 from the atmosphere and using it to make possible carbon materials that would be used in aerospace and other components.  The question of carbon removal usually includes some method of storing it.  Futurism.com has …

Dr. Brien Seeley, founder and President of the CAFE Foundation, shares this important news. SANTA ROSA, CA.—On April 29-30, 2011, an outstanding faculty from NASA, industry and academia will present the technologies necessary to inaugurate the Age of Electric Flight.  The 5th Annual CAFE Electric Aircraft Symposium (EAS V) will reveal how safe, emission-free, 2-4 seat electric aircraft could soon make a doorstep-to-doorstep round trip from San Francisco to Los Angeles on a single battery charge at nearly twice the overall trip speed of airline travel.  The latest breakthroughs in energy storage, motors, quiet propulsion, powered lift, electronic pilot assistance, autonomous flight and aerodynamics will be presented along with proposals for how they can transform transportation. EAS V will again network …
