microwaves stories

Most military weapons systems rely on sophisticated electronics for control, so if you can somehow knock out the circuits, the weapons will become useless. A new type of missile tested last week by Boeing and the USAF exploits this vulnerability, by zapping selected buildings with microwave energy so powerful that all electronics inside will stop working.
Microwaves aren't very smart. It generally has no idea what you're trying to heat up, and if it's (say) a burrito and not (say) a frozen turkey, a bunch of extra microwave... waves... are going to waste. This blue box can suck up all of those spare microwaves and turn them back into electricity that — wait for it — can power your microwave again.
