Or did you think the challenger mission was faked up in a hollywood studio? No. I do think it was caused by a *mixture* of hydrogen and oxygen. Or do you think the yanks lied about it? " At 73.124 seconds, a circumferential white vapor pattern was observed blooming from the side of the External Tank bottom dome. This was the beginning of the structural failure of the hydrogen tank that culminated in the entire aft dome dropping away. This released massive amounts of liquid hydrogen from the tank and created a sudden forward thrust of about 2.8 million pounds, pushing the hydrogen tank upward into the intertank structure. At about the same time, the rotating right Solid Rocket Booster impacted the intertank structure and the lower part of the liquid oxygen tank. These structures failed at 73.137 seconds as evidenced by the white vapors appearing in the intertank region. Within milliseconds there was massive, almost explosive, burning of the hydrogen streaming from the failed tank bottom and the liquid oxygen breach in the area of the intertank. At this point in its trajectory, while traveling at a Mach number of 1.92 at an altitude of 46,000 feet, the Challenger was totally enveloped in the explosive burn. The Challenger's reaction control system ruptured and a hypergolic burn of its propellants occurred as it exited. the oxygenhydrogen flames. The reddish brown colors of the hypergolic fuel burn are visible on the edge of the main fireball. The Orbiter, under severe aerodynamic loads, broke into several large sections which emerged from the fireball. Separate sections that can be identified on film include the main engine/tail section with the engines still burning, one wing of the Orbiter, and the forward fuselage trailing a mass of umbilical lines pulled loose from the payload bay. source: "Report of the Presidential Commission on the Space Shuttle Challenger Accident," U.S. Government Printing Office : 1986 0 -157-336.) -- Robin reply-to address is (intended to be) valid |

Articles like this gloss over a lot. And they all present it. In one sentence per paragraph. I don't think gas is a showstopper as such. Better to use renewable electricity for the say 90% of the time you can, and generate electricity from gas only when needed to bridge intermittency (and no other storage is available - batteries should handle short term grid stability). Result is a 90% decline in carbon emissions. Power stations are also much easier places to fit CCS than everyone's boiler flue. Obviously there's a whole load of economic implications (upgrade the grid; pay to keep stations idle, not pay them per unit of generation) but it doesn't seem technically problematic. Theo |

Why would there be ANY?. Plutonium is so un-radioactive that there is more danger from e.g. inhaling lead dust than plutonium dust., Its very heavy, so it hits the ground early. Far worse to have someone e.g steal a cobalt 60 source from a dentist and leave it in a tube train. Or sell it for scrap, and have it melted down and turned into new products like metal chairs and table legs, as happened in Brazil |

Im assuming that only professional installs can be banned. A non-professional gas installation voids your household insurance. Mine has been running happily since 1989 :-). Two British GAs engineers were jailed for manslaughter after one installed a flueless gas fire badly and the other did not replace the case correctly on a fan-assisted boiler that had a case that was under a positive pressure, or something like that. |
