Sorry shine, you are right:
1. 12V will create enough power to trigger the EMP. AA cells are not sufficient.
2. Cooking remotely placed sausages, exposing people and structures to non-ionizing radiation, and stopping vehicles with no aparent reason is entirely legal. Sorry if I misunderstood your good faith.
My next project is creating a substance capable of sudden expansion of the material after initiation, usually accompanied by the production of light, heat, and pressure.
