Isn't the purpose of "cooking" cables just a matter of moving valence electrons around to break in a cable?
Can't someone just have an appropriate source of current and voltage such as a power supply of the proper voltage connected to the cables and then to a lightbulb, motor (or similar) and accomplish the same goal for pennies on the dollar? This is just how my mind works...
That should do it.... 10,000 dollar cable "cookers" are more for guys with IQ below room ambient temperature.
