How long will my fridge magnet stay attached to my fridge? Are you saying that a permanent earth magnet is going to lose its power in a 20 or 30 years? These things have been underground for millennium have they not? Thanks for your answer though... |

How can anything ever fall into a black hole as seen from an outside observer? @daNpiponi read the original question. It is pretty clear from where we are measuring. |

How much of the energy from 1 megaton H Bomb explosion could we capture to do useful work? Awesome answer! Thank you mmc! Full marks from me! |

How can anything ever fall into a black hole as seen from an outside observer? @danpiponi oh dear dan. Do you think that it is just a red shift issue. That the object continues on its way? What about gravitational time dilation? The objects time stops as from the observer. You not be able to see it anymore but gr clearly states the object will slow and will never cross the horizon. Read all the other posts on this page! You appear confused on this issue... |

How can anything ever fall into a black hole as seen from an outside observer? @DanPiponi I have read a lot about this, but never had a clear explanation as to why in poplar science black holes exist and are active in "consuming matter", when at the same time we are taught through GR that from any reference point outside of the event horizon as an object approaches the horizon its time, as it appears to all objects outside of the horizon, wil stop. I see you can't explain it either... |

Your right though all of these will have a fission trigger so our "facility" will get pretty contaminated! I found this link, but it is still only theoretical:- en.wikipedia.org/wiki/Pure_fusion_weapon looks like my idea may not have the legs I thought! |

How much of the energy from 1 megaton H Bomb explosion could we capture to do useful work? I like your analogy. However, there is a lot of energy locked up in a h bomb. Just say we could tap into 10%. I have calculated that is 155,000 mega watts of power. You know it was not that long ago we were going to use H bombs to power a spacecraft so I don't see why the idea is so crazy! en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion) |

How much of the energy from 1 megaton H Bomb explosion could we capture to do useful work? But... we did get quite good a making them, so if we could build a facility to harness the energy would this not be a quicker (if not far more ugly) way of implementing "fusion power"? |
