What are Boeing looking for / researching with the Ecodemonstrator

What about it?

So today I excitedly spotted the Boeing 777-200ER ecodemonstrator and was wondering what the purpose of a 5hr flight over Europe is? Surely they can do all the tests etc in the US without the need to base this aircraft in the UK for a bit etc. I assume as this is a 20yr old airframe it has the new eco items on it rather than just flying a 20yr old airframe about. If anyone knows would be really interesting!

ELI5

What about it?

I know jet engines are as easy as compressed air + mixture of jet fuel + combustion = thrust, but can someone give me some insight as to why there are so much piping around the engines and what it all does…

Got to see this beauty today at KSTL

It brings me great joy keeping this beauty clean
