PROBLEM: HOW TO DETONATE WOULD-BE SUICIDE BOMBERS LOADED WITH EXPLOSIVES

Heat rays or microwaves? Remotely exploding explosives via microwaves. This was a technique used in a comic book by Batman who remotely detonated explosives floating in the harbor of Gotham City.

Farfetched? Not so far fetched as you might think. Look below:

"For example, directed energy may permit small elements to destroy targets they could not attack with conventional energy weapons. Directed energy may permit the achievement of EMP (electromagnetic pulse) effects without a nuclear blast. Research in superconductivity suggests the possibility of storing and using large quantities of energy in very small packages. Technologically, it is possible that a very few soldiers could have the same battlefield effect as a current brigade."

Is anybody working on this? It may prevent a lot of grief and remove undesirables at the same time.

P.S. Could such directed energy be used to explode IEDs?
