I think he’s talking about the cost of electricity generated with coal which includes the cost of the coal, the plant, upkeep and profit. Although, it would have been more clear if he said megawatt hour instead of megawatt.
His point is valid, he’s considering how many megawatts a unit would have to make to pay for itself.
I would go a step farther, since all this unit is doing is making low quality heat, payback should not be measured in megawatt hours but in BTU’s. In other threads there was bragging that you could make 10 megawatts of heat with 1 megawatt of electricity. If this is true, it is a failure, there are cheaper sources of heat, and it may not even compete effectively with a heatpump.
And don’t start name calling, I’m assuming that this is not a scam.
Utterly, completely, totally false. Worse, such a statement is ignorant. It is like saying that 20 nickels makes ten dollars.
I’m including everything, capital costs, operating costs, all of it together. If this device here has such a high initial capital cost, then even if it runs for nothing, it has to run for a long time to make up the difference in the initial outlay.
It’s like an electric car. Sure, electric might be cheaper than gas, but if you’re paying 30k more, that can buy you lots of gas.
