Ja, helium wants to be free.  That stuff is hard to contain.  Any tiny crack 
or imperfection in any joint or anywhere and it's game over man. 

So maybe the real limiting factor is how well the cooler can survive actual usage (and the occasional bird in the intake). I have the impression that this is finicky technology, despite the good people behind it.


But it would be awesome to get to space using UK technology, just for the sheer unlikeliness of it (for those who don't know, the UK always looks a bit shoddy since the place industrialized first and got stuck with an infrastructure generations behind).
