Heh, you're right; I thought that design looked like a juke box record changer. Remember that old tune? o/~ The music goes round and round and it comes out here o/~ Cool concept; I wonder what the power requirements for the magnetics would be, and how much thrust it'd generate. Probably like an ion drive. I recall a polomium isotope being proposed for this application but this is the first time I actually understood how it was supposed to work. 1 million second Isp ain't shabby. --Damon |

I sure wouldn't want to be standing behind the exhaust nozzle of that thing, considering what's going to be flying out of it. Scott Lowther is working on a new model kit of the Vought SLAM intercontinental nuclear-powered cruise missile at the moment BTW: http://up-ship.com/blog/?p=7587 Coolest thing he ever did is still the Orion nuclear-pulse Space Battleship: http://fantastic-plastic.com/Project...leshipPage.htm _love_ the destroyer gun turrets; just fukin' kneel! I wouldn't mind having one of those about three feet long hanging from the ceiling. Pat |

Pat The dusty reactor concept for the fission fragment rocket is interesting (mostly cuz my thesis was on particle charging in dusty plasmas). However, I propose a variation that could not easily get too hot and might make the entire thing simpler..........A Thorium based "energy amplifier" fission fragment rocket where we use a high energy proton beam to start the reaction. It never goes critical so heat loading can be more easily controlled. Power level is controlled by the flux of protons from the beam. Power for the beam is produced by the "energy amplifier" when the charged fission fragments pass thru coils on their way to produce exhaust. |

Apparently electricity generation is not only possible this way, but very, very efficient. Vastly more so than by thermodynamic methods. A thorium fuel cycle looks extremely attractive. --Damon |

As long as we are discussing strange fission engine designs, Scott Lowther has a three-part article on the "nuclear lightbulb" engine design on his blog: http://up-ship.com/blog/?p=6542 http://up-ship.com/blog/?p=6604 http://up-ship.com/blog/?p=6694 Pat |
