Hollow fan blades?

? are you referring to the hollow fan blades on the Pratt&Whitney engines on the Boeing 777 ?

Yes! That's where I heard that and was trying to ask about other hollow parts like a crankshaft. Then I got a text and ran off the road. LOL Sorry for the half arsed post.

Seriously though I was wondering if that is possible on something like an F1 car where money doesn't matter. Hollow parts to lighten the motors? I've never thought of that and am curious. Thanks.
