Raising the effectiveness of electricity generation (per unit of fossil-fuel combusted) by less conventional means

Proposed, conceptual designs and applications for a cascaded system for electricity generation, employing “waste” heat from a primary stage as the stimulation for a subsequent stage, are outlined. The use of solar energy, wind and/or hydropower to supplement the energy inputs to the second and third stages is also considered. Present and future economic viabilities of the proposed hybrid electricity-generation systems are assessed qualitatively.
