When you say that "Cold Fusion at 300C would be fine for automobiles ...", you have to take into account the fact that the 300C is the loaded temperature of the system. In RF technology, it is commonly known that to get maximum transfer of power from a real source having a real source impedance (in a linear system), the load resistance must match the source resistance. If you have a 50 ohm source, then you apply a 50 ohm load to extract the maximum power from that source. But, the operating voltage across the 50 ohm load is 1/2 of the voltage of the unloaded source.
So, in any practical LENR system, the fuel temperature will be much higher than the actual operating temperature of the working fluid (maybe twice as high). I think a better FUEL temperature range for LENR would be in the 400-600C range for an apparatus with a working temperature of 300C.
