This is an almost exact model of the Rolls-Royce Trent 1000 jet engine - the same engine that powers the Boeing 787 Dreamliner. The only difference is that this one is made entirely of Lego.
On display at the Farnborough Airshow 2012, this working, spinning, model is quite the sight to behold. It wasn't put together by Rolls-Royce but by a specialist Lego construction team which certainly had their work cut out for them - quite the step up from the Lego Xmas Tree.
The real Trent 100 has fan tips moving faster than the speed of sound but those of this 152,000 Lego brick model were moving considerably slower at the time. The Trent is also capable of compressing air into a space 50 times smaller than its original volume but we're not so sure that the super structure of this version is quite up to the task.
Were you to buy the real McCoy, you'd be the proud owner of a jet engine in which each blade produced the same horsepower as a Formula 1 car with fuel burning at 2000C, roughly half the temperature of the surface of the Sun. Your choice as to which would do better in your living room.
