This engine is absolutely amazing because it is built out of Lego. The engine took four months to build and actually does work.
Of course, when I say it actually works, I mean it obviously wont be powering a full sized car or anything.
The Lego engine is in a V8 configuration and while the camera moves around on the video below you get to see many parts of the engine moving such as the fan, pistons and other various engine parts inside. The controller you see on the picture to the side here allows the speed of the engine to be changed.
It must take some serious skill to build something out of Lego with this much detail. I highly recommend you check out the video below to see the Lego engine in action.
