      you'd use a heat sink.  A big box of rocks works about as well as anything.

          I might do a flowsheet sometime for this.

            thermodynamics is thermodynamics, and discarding calories for economic reasons doesn't let them be ignored in an efficiency calculation. the only way a system like this can achieve the efficiency numbers (and I actually am a fan, even though it doesn't sound like it) is to make use of and recycle the downstream losses.

              I worked in industrial gases for 26 years, and this kind of thing has been used for 80 years in liquefiers to recover the energy used in liquefaction.  This would just be on a bigger scale.
              Trust me, the thermodynamics works out.
