So to produce 200kW for 40 years and cost $0.05 a kWh means the total cost of the unit is around $3,500,000.

Assuming it can’t dangerously malfunction, the real question is what can people who are bent on doing harm do with it?

We can’t run away in fear from new technology. Look what 19 people did with box cutters.

You aren't factoring in the time cost of money.

This thing produces $10/hour of electricity, or $240/day or $87,600 a year. With a 10% interest rate, the present value of that cash flow is about $860,000. At 7%, it goes to about $1,170,000. That's still not cheap for any vacation home except maybe Ted Turner.

of course, using it for point power means you aren't going to be running at full load all the time. So, at half load, the price/kwh (assuming most of the cost of the plant is capital, not fuel) would go to about 10 cents/kwh.
