instead of mixing hydrogen and oxygen
put foam epoxy that solidifies (as a filler) in it and fire it.
then the foam solidifies and if you run out of fuel or air up in space then climb down.

I remember a similar idea being proposed in the "Daedalus" section (long since defunct, alas) of New Scientist magazine many moons ago (I'm not saying Technobadger's idea isn't original: In fact I like it: just that it was also invented independently by Daedalus). Among the applications suggested for the foam rocket were emergency bridge construction. "Soldier! Bridge that canyon!". "Sir, yes sir!" <whoosh>. Instant bridge. |

what happens after the trip? do you just leave the foam there or does it have to be destroyed? |

we don't know, but it sure as hell would make architechture an interesting hobby |

How do you keep the "rocket" on track when you reach the stratosphere and get hit by the jetstream ? You're not going fast enough to use aerodynamic steering, and the sideforce will be considerable .... |

This would be cool. You could shape the nozzle so that the pillar was hollow, and put stuff up it. |

Bad - epoxy foam would ( almost certanly ) be too weak, you'd have to go all the ways up to geo stationary orbit, the foam would have a low specific impulse ( need to bring even more fule ), and it'd take forever to climb down. |
