'horizontal machines" at the General Electric Lamp 

 Plant In Bucyrus, Ohio, running from glass-furnace to 



finished lamps as fast as four per second and 



often sell at 79« at the hardware store. Then 

 following that 'comparable' example, a modified 

 'machine' might be able to produce 630 HH of capacity 

 per year at $158/kH If the resultant '5 Hatt Power 

 Tubes' sold at 79* retail.

A 'Solar Voltaic Unit Generator: Chronology of 

 Technical Readiness' is Appendix A to these Remarks. 

 It shows the progress in module efficiency and cost 

 related to the various DOE Programs. DOE Program Plans, 

 attempts for PV power plant, and Congressional actions 

 on behalf of large-scale solar photovoltaic generation, 

 from 1973 to the present. The various "goals' set by 

 the Congress and DOE PV Programs, and often met in 

 "technical readiness", provide a fair guide to factory- 

 costs when mass-produced, upon which to anticipate 

 energy option offers to plug in to a BPA Interface 

 Substation and earn a return on the SVUG factory cost?
