Wow, that is truly amazing, and frightening.
That's something we'd better protect very closely. And also something that we'd need to shield our own power grid against. Can you imagine the chaos if the US were to lose power for even a few days? Just about everything stops. The reaction of the people could do more damage to our towns, cities, states and even the country, than the weapon, itself.
The possibility of Marshall law, the possibility of anarchy.
Remember, even many emergency generators run on computerized systems.
That could very well be the single most powerful weapon since the atomic bomb. Really cool, but also quite frightening.
I's only a matter of time between having the ability to target single buildings and areas, and have the ability to target national power grids. In fact, the more concentrated we make our power grid control, the easier a weapon such as this could take out large portions of our national power grid.
Something to think about. The USSR developed their Atomic Bomb by stealing the secrets of ours because of faults in our security. The same could happen with this, obviously, because based on the secrets that have been lost over the last few decades, our top secret security is still fairly porous.
