Some think you are joking but I can understand shy some have trouble with this concept. it's an unfortunate characteristic of thermal cycles that heat must be rejected to enable a closed cycle. It's a big energy waste but applies to all cycles that use steam, in that steam must be turned back to water and that requires the removal of energy. don't think it's necessary to belittle someone for not knowing this, if your not into thermodynamics it's not an easy concept to grasp
