"But unless my calculations are wrong — which I hope they are, by at least three orders of magnitude — if we gave up burning fossil fuels today, we would have to reduce our energy consumption overnight to 6% — six percent — of what we currently consume"

Aviation-fuel and generating capacity
I wrote in my last piece on aviation fuel that I thought that electrolysing the amount of hydrogen needed to fuel the world's jetliner fleet would use more electricity than the world's entire generating capacity, but that I would have to run the numbers. Well, now I have.

AvBrief has what looks like the real scoop on the AOPA board firing Darren Pleasance. By all accounts, he was actually effective as a CEO, turning the organization around significantly during his short tenure. Maybe some board members were threatened by having someone more competent than themselves, or maybe just more honest, in the CEO seat.

Reducing aircraft soot might not actually reduce the climate effects of contrails
Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails from aircraft contribute to the climate-warming impacts of aviation. The findings demonstrate that more work is needed to understand and reduce the climate impact of jet engine emissions.

Hybrid engine could reduce aviation emissions by up to 30%
In the future, regional flights such as Trondheim-Oslo could become much more environmentally friendly with the help of a hybrid aircraft engine. This type of engine combines an electric motor and a combustion engine to drive a propeller. The innovation should be able to reduce CO2 emissions by up to 30%.

Went for another training flight today, ran into an examiner by pure chance after landing, he had time, I had time, we could shuffle things around to free up a plane. An hour later, my single engine piston (land) class rating is restored. Yay!

American Airlines and Google say AI helped airplanes reduce contrails that trap heat
American Airlines and Google said Thursday that they significantly reduced the climate impact of some of the airline's flights using an AI-based forecasting tool to help prevent contrails.
