Even if it runs on nothing, it still has to recoup the cost over the life of the machine. If it were 100 dollars per megawatt, it would be competitive. At 100 per KW, things would have to get much more expensive before it would enter serious production.
At $100 construction cost per 1KW of generating capacity, it would pay back its construction cost in FOUR MONTHS.
9000 hours per year of operating time means 9000kwh/yr. At retail price of 3 cents per KWH, that is $270/yr. At a more typical household rate of 10 cents per KWH, it would pay for itself in 6 weeks.
You must be using that “new math” the Dims are teaching kids these days.
