CONTRAIL AVOIDANCE
Aviation now needs a Tesla moment, like cars in the 2000s ¡ª decarbonising demands disruptive new tech: Robert Miller
Robert Miller, Director of the Whittle Laboratory, highlights the need for disruptive technologies like cryogenic hydrogen fuel and hybrid electric flight to achieve net-zero aviation by 2050. He emphasizes four Sustainable Aviation Goals: mitigating contrail-induced cloud formation, enhancing system efficiency, scaling up sustainable aviation fuels, and investing in experimental technologies like hydrogen-powered aircraft.
Decarbonising aviation is vital for climate action as a rising non-Western middle class starts to fly ¡ª COP28 has raised this ambition: Robert J. Miller
Aviation directly contributes 2% to 3% to total greenhouse gas emissions. But it also has non-CO2 effects ¡ª when a plane flies at a certain altitude, it sometimes leaves a persistent contrail, the cloudy line at its back. At times, this forms clouds and traps heat to Earth which can raise the effect to 6%. Now, in 2018, only 11% of the world flew. But a rising middle class across Asia, South America and Africa will be flying soon ¡ª that 2% or 6% sum will increase, Robert J. Miller is Chair in Aerothermal Technology at Cambridge University said.
New Farakka Express derailment: Preliminary enquiry indicates glitch in train's guiding system
The report of the Commission of Railway Safety (CRS) released Tuesday suggested the reason behind the derailment was that it was given a green signal despite the point failure.
Altering flight routes may cut climate impact by 10 per cent: Study
Aviation is different from many other sectors, since its climate impact is largely caused by non-CO2 effects, such as contrails and ozone formation.
Here are some lesser-known facts about flying
Things you never knew about flying like why do airlines dim the cabin lights for take off and landing.
