Although 90% of the video is just a blurb for the manufacture of the engine, the heart of it in terms of technology is a VERY cool use of 3D printing to make jet engine parts.
Yeah, GE has been working on the LEAP program for probably 10+ years now. I believe it's viewed as sort of the replacement for the CFM-56 that you find on the Boeing 737 line of planes. It's certainly cool with its 3D printed parts but I don't know that it's all that futuristic beyond that. It still operates the same way as any other jet engine.
