“…We can also write where qd is the wall-plug to output driver efficiency, and Pa,, is the amount of recirculating power that is used to drive plant equipment other than the driver. The idea behind any feasible power plant is to reduce the cost of the plant for a given output power, P. Zukerman, et al, (1988) do a detailed study of the cost of a heavyion fu3ion power plant versus various physical parameters. The cost increases as the driver energy, Ed, and the recirculating fraction, fp, are increased; therefore, for fixed .…”
