All our most ambitious plans in space revolve around a transportation system. Nasa should tell Congress that this was the LAST shuttle flight, they are too dangerous. Let me ask you, looking into the future what is our biggest problem facing us? Isn't it our global energy needs? In fifty years or so we need to replace oil with other sources. Solar energy, collected in space, is the ...only... practical path. Fusion is a pipe-dream. Here is another Nasa dream that needs to be pushed forward. http://spacesolarpower.nasa.gov/ Mars will have to take a back-seat, we can't wait ten years for a replacement. Jonathan s |

Coal liquifaction should see us well into the 21st century, assuming the whole world industrializes (centuries if they don't). I also hear tell that there's this atomic power stuff from the pulps that looks promising and a certain amound of uranium and thorium in the Earth's crust, to the tune of about 10^30 joules worth or about equal to the energy in 160,000,000,000,000,000,000 barrels of oil. Humans use use about 10^13 watts but most of us are poor: multiply that rate by 20 and there's enough fissionables to last us about 160 million years. If we'd got started using atomic power in the late Jurassic, we'd just be running out now. -- http://www.cic.gc.ca/english/immigrate/ http://www.livejournal.com/users/james_nicoll |

If we'd got started using atomic power in the late Jurassic, we'd just be running out now. And what about the rest of the world? When will, say, Indonesia, India or Mexico get to build dozens and dozens of nuclear power plants? And what about climate change when the rest of the world becomes industrialized and is then burning ten times the fossil fuels we are now? I don't see a future in that. -- http://www.cic.gc.ca/english/immigrate/ http://www.livejournal.com/users/james_nicoll |

Solar power satellites are dangerous and expensive - only an L5 habitat could make them economically.
