The good people over at Rolls-Royce love Lego blocks, too. How do we know? The company's engineers created a half-size replica of its Trent 1000 jet engine that powers the Boeing 787 Dreamliner, using 152,455 of the plastic bricks.
That's not even the coolest part. The engine parts actually move, just like their full-size counterpart.
This shows the Lego jet engine was a labor of love for the Rolls-Royce engineers, who put the same techniques toward planning and building the Lego version as they would a real engine. They created 160 separate components that fit together just like the real engine — including things such as the fan blades and even the internal combustion chamber.
The Lego jet engine is just under five feet long and six-and-a-half feet wide and the beast weighs 676 pounds. Even if it didn't have intricate moving parts, the size of the model alone puts it on the cool list.
The model took eight weeks to complete and included actual Rolls-Royce employees in the build. Rolls-Royce unveiled the model at the Farnborough International Airshow in England.
Sure, there are literally hundreds of other brilliant Lego creations out there, but this one won me over with the complexity of the turning parts. A time-lapse of the engine coming together, seen below, shows the impressive work as it progressed.
