The real problem is basic thermodynamics.
The efficiency of a theoretical Carnot engine (the most efficient engine conceivable) is 1-T(cold)/T(hot). This implies that as you approach absolute zero, the efficiency of any heat transfer device tends to zero. So you need to do an infinite amount of work to remove the infinitesimal last bit of heat from your sample.
