For example, the military has a remote controlled "fly-bot" which can fly around and send back an audio/video feed, which also happens to recharge when near a magnetic field (i.e. computer monitors, speakers, cellphones). Amazing.
There's a hydrophone network on the seafloor around the world, which can monitor ship movements around the globe. Nice.
They also have a "snowball gun" which takes in snow and fires ice bullets so there's no need to lug around any ammunition at all in arctic environments. Wow.
I kind of guessed this as I was reading the book: Did you know that lobsters, shrimp and crabs are essentially oversized insects? Yummy.
Oh yeah the book is pretty good too.

I'm glad you enjoyed these two books. Next time I read a good one, I'll let you know.
