More and more of us fly every year. As we do so, the political pressure to act to curb greenhouse gas emissions from planes is rising.
Eh? Here in the US our conservative politicians couldn't seem to care less about emissions. I never hear about new measures for reducing plane emissions in the domestic news, and the US members of this forum tend to brush aside any suggestion that anything serious needs to be done. Too bad we have the largest airline market in the world.
The Silent Aircraft Initiative (SAI) team has succeeded in coming up with a radically quieter plane. Crucially, the SAX-40 is also 35% more fuel-efficient than any airliner currently flying.
I wonder how this compares to the expected increase in passengers numbers.
For manufacturers, it is much safer to develop new airframes out of what has gone before, rather than re-tool completely with a brand-new production line. Yet with increasing concern over climate change, we could see a radical shift in aircraft design. This would be more likely if airlines had to pay "green" taxes on their airliners' emissions of greenhouse gases. But the skies are not going to fill with radically new aircraft shapes any time soon. When an airline buys a new plane, it will keep it flying for decades in order to make it pay its keep. Which means even if this design gets the thumbs-up from the manufacturers, we won't be queuing up to board planes like the SAX-40 before 2030 at the earliest.
So, anybody want to guess that we'll have 35% more passengers by 2030, thus completely negating any possible benefit this design might have given us? The environment is a joke, a marketing tool, a bullet point on a brochure and nothing more. Trust me folks, the battle is over. The cronies won. You can vote with your ballot, you can vote with your dollars, none of it will change anything. We're all on a slow march to a more polluted planet and nothing can change our course at this point.
