Aeronaut; I agree with your basic premise but I think you underestimate what could be done for $3trillion. 5,000 to 15,000 FF installations? Rematog says “At the most optimistic, (20MW power blocks with installed cost of $500k ea), repowering America’s electrical generating capacity will cost about 30 BILLION dollars”. On that basis $3trillion gives you 6 million units or 1,000 times the total US requirement. How would that rate on the score card that started this thread.
