Wrong. The ECat at low gain would be valuable to the segment of the population whose only affordable alternative is a resistance space heater COP=1 versus LENR heater COP=3. Next is the home electric water heater. For them, net power for heat is cut by two thirds. DoE says space heating and water heating are the largest consumer of energy in U.S. residences, accounting for approximately 15% of total electricity usage.
Savings from this market alone in the USA is a minimum $15 billion annual - from a COP=3 device - if it is safe enough for home use. The low gain is valuable to the those with daytime solar power, needing to maximize house heating from a limited amount of electricity, or at night from electricity stored by batteries. . so little imagination, so much debilitating stubbornness. From: Joshua Cude A COP of 3 is not useful if the electricity was made with fossil fuels at an efficiency of 1/3. That's a wash.
