Kudos to RR engineers, but when I read that this engine is "powered by 100% Sustainable Aviation Fuel (SAF)" and that it "is derived primarily from waste-based sustainable feedstocks such as used cooking oils" I am dissapointed. Maybe there is enough used cooking oil in the world to power all the jets (now and in the future) but it first needs to be gathered. And that is expensive. Which will lead to unused cooking oil to be used. And, in the end, it will raise food prices as that oil is needed for human food preparation. |
