It’s actually more like 1.666, and that only after investing more than $1.5 million in a highly problematic e-cat machine. The grid price of the 200 kW of sustaining power at $0.10 kWh is about $20 hour; say $500/day. Natural gas is presently trading for about $3.65 mmbtu; that is to say $12.50 buys 1000 kWh worth of raw heat from NG. About $300/day invested in natural gas buys the same amount of heat the megawatt ecat produces for $500/day. Why not just make all the heat from NG and save $200/day of operation and deny Rossi the $1.5 million ecat front money? The low-grade heat 1 mW ecat might start to make economic sense if the actual COP is better than 20/1. At 6/1 it’s a non-starter. Is there anyone out there with $1.5 million who is so innumerate as to think paying 66% more for low-grade heat is a good deal?]]> Sounds goofy. Supposing the ecat gadget works as claimed, which is highly doubtful in itself, 200 kW of sustaining electrical energy is produced thermally by burning NG at a common efficiency of 33% heat to electricity, then 600 kW of high grade NG heat is consumed to produce 1000 kW of low grade ecat heat. That hardly sounds like a COP > six. It’s actually more like 1.666, and that only after investing more than $1.5 million in a highly problematic e-cat machine.
