Ok, but isn't the gold thing also essentially destroyed in the process? As far as I understand, for it to work,it has to be supremely smooth, or ot fails to generate the required patterns. Can it be re-used for a second pulse, after it is exposed to the thermal stress of the millions of kelvins and the mechanical stress of the explosion?
So the extremely precisely machined piece of heavy metal is essentially part of the fuel. That seems like a no-go for commercial energy generation without any firther discussion.
