Rail Guns
Okay, this may not seem like “fun” to everyone…
But, this article on Slashdot about rail guns got me. Apparently, the US Navy plans to have rail guns installed by 2011. That’s not all that far away.
For those of you not familiar, rail guns are basically high-speed catapults driven by very, very powerful electromagnets. Very science-fiction stuff. And, the Navy plans on having working rail guns on actual ships by 2011.
Cool.
