The Doctor Who Instagram account has long been releasing teases and hints from behind-the-scenes of series 9 during filming, many of which have had us confused and excited – but one of their latest posts really has us scratching our heads.
Apparently showing schematics for some sort of engine, the post speculates that the diagram could be a plan for some kind of time-controlling device, or just where the Doctor gets his espresso. Both fine choices – but what could it really be?
An obvious choice could be some sort of redesign for the Tardis, or at least a new component – could the Doctor finally be replacing the drive stacks as suggested by Perkins (Frank Skinner) in Mummy on the Orient Express? The part on the right certainly looks quite Tardis-like, almost akin to the main console. Maybe it’s even a design for another Tardis (which might have even appeared in the series 9 trailer).
We do like the idea of a continuum shifter though, whatever that is – sounds like something that might be useful in finding a planet that’s lost outside the usual continuum of time *COUGH* Gallifrey *COUGH*.
Alternatively, the plans could be for some sort of Doomsday device, or something else dangerous that the Doctor and Clara must stop in the new series. Perhaps Missy (Michelle Gomez) has a few new tricks up her sleeve…
To find out more, we had a chat with some science types who (in a very brief look) reckoned the design looked like it was for some sort of turbine, with the equations around possibly relating to fluid dynamics.
As the basic point of a turbine is to generically move air or water through something (early turbines were windmills and waterwheels), perhaps (in our inexpert opinion) it could just be a liquid (or air)-powered motor for something used in the series. Perhaps it’s even a liquid cooling system for a Tardis that has been overheating a little? The Doctor has to get his DIY kicks somewhere.
That said, you have to wonder – propelling liquid does sound like something that would be useful for a Time Lord coffee machine…
Doctor Who series 9 begins on BBC1 on the 19th September
