Here’s my understanding of what Rossi has said:
Initial cost will be 1 cent per kWh
Nickel is the 25th most common element in the world. Rossi says the amount needed for his device should not impact the cost of the raw material (meaning it doesn’t use up large quantaties)
The waste is not radioactive.
I’m hoping he’s being straight with us.
If he can deliver electricity for a penny a kilowatt hour, that would be astounding. That is less than half of what coal generated electricity costs which in turn is less expensive than gas fired, nuclear, wind and solar which encompasses the current and proposed alternatives.
But people would pay good money for something that will heat their homes in the winter for negligible fuel costs (replacing a small nickel/hydrogen canister once a year). I don't know about you, but I spend more to heat my home in the winter than I spend on gasoline.
