For most of us, having access to electrical power has become so second nature that we hardly give it a thought. It's so abundant to be almost free, and there are lots of places all around to plug in your cell phone when it runs out of juice.

As you probably know you can use radio waves to talk to people over the air. But did you know you could also send digital signals as well?

Earthquakes are rough. They come from out of nowhere and can be extremely serious very quickly.

They often lead to other circumstances: fires quickly spring up from broken gas lines and downed power lines.

And they almost never happen one at a time, aftershocks a commonplace and can be even more damaging than the original quake.
