For those of you who've lost hope that you'll ever have a robot butler or drive a hovercraft, here's a glimmer of possibility: a jet pack! Thunderbolt Aerosystems has developed the Thunderpack, a "rocket belt" that can propel you through the air at up to 75 miles per hour. Okay, so it will only fly for 45 seconds. And it'll cost you $100,00 to buy one. Then there's the fact that I'm sure a few safety-freakish representatives of Congress will do everything in their power to keep these out of the sky. But they're still jet packs, for heaven's sake!
