If this is true, this will be revolutionary. It means if one spends $50 on a device generating 1 kW of thermal power, or about 300 W of electric power (due to inefficiencies of steam-turbines), the average amortized cost per electric kWh over 1 year would be about $0.02/kWh. This is 1/5th the average worldwide domestic electricity price ($0.10/kWh)!
