1/4 cent per kWh implies both substantial over-unity operation and some proven way to convert the various fusion products, including thermal energy if applicable, into electricity. It would also seem to imply a very generous estimated lifespan of wear parts like the electrodes, which begs the prospect’s most pressing question: “What is my TCO total cost of ownership?” A related question would be regulatory requirements, overhaul schedules, and overhaul budgets.
Your 1/4 cent per kWh may well be 20 years down the road unless you can line up substantial subsidies.
