As the price rises, helium recapture and liquefaction will become more common. As recapture and liquefaction becomes more common, the price of the necessary equipment will tend to drop. There is an experiment in our lab (ADMX, an axion search) for which it is already financially more expedient to re-liquify. In addition, new cooling technology is becoming more prevalent. Closed-cycle pulse-tube cryocoolers are becoming common throughout physics.
