I didn't say the engineers weren't aware of the potential dangers, nor that they in any way had bad designs. You suggested that good design was inspired by the protests. Clearly it was not, the designs were already good at the time that the protests took place. I was only pointing out that gadflies can actually provide some service in bringing these kinds of things to the public eye, and helping ensure that an issue really is properly reviewed. It had already been properly reviewed since the technology for robust RTGs had already been developed, had been utilized and even been proven in real life accidents, BEFORE the protests. If you read the safety report for a mission that uses RTGs, it is clear that special effort is made to address any public concerns. The protesters aren't really concerned about nuclear contamination, they have other agenda that are the real reason for their protests. |

I agree that most people have no clue about actual risks. But the risks with RTGs are real, and the odds of an accident very high. Rocket launches fail all the time, with loss of the payload. That's a very difficult environment to consider when maintaining containment of dangerous materials is critical. A huge effort goes into designing RTGs with that in mind. Yes, because of the care that goes into the engineering, the actual odds of a failed RTG launch causing human or environmental harm are low. But that's because the high probability of an accident has been considered in the design. Which was already very good even in the 1960's, before most of the protesters had any idea of what an RTG even was. It is because the odds of actual harm are low that you don't find many people opposing these launches. Most people never even have any idea when a launch is about to take place. It isn't a standard position of environmentalists to oppose them. And it's why the few who do oppose this technology have not had any real success in limiting it. The few who oppose this technology are also unhappy about other technologies, generally. |

The protesters _themselves_ may, for the most part, be genuinely concerned about nuclear contamination, but some of them, as well as some whose writings inspire such protests, do indeed have another agenda. American leadership, in technology, in industrial capability, and in military might, is necessary for the continuance of world freedom, and it has indeed been opposed by people who would have preferred the Soviet Union as the model for the world for quite some time - and despite its fall, this sort of thing has long continued.

Define "freedom". The freedom to be poor, oppressed, hungry, sick and homeless? And that's only Americans working long hours on minimum wage. How long before shanty towns start springing up around the soup kitchens? Bah, humbug? |

Define "freedom". What Western Europe purportedly had after WW II ended. The freedom to be poor, oppressed, hungry, sick and homeless? Such as the way things were in Europe in WW II? And that's only Americans working long hours on minimum wage. And twelve million or more illegal aliens. How many illegals in Denmark, again? How long before shanty towns start springing up around the soup kitchens? Bah, humbug? This article will be difficult for you to understand: http://www.nytimes.com/2010/08/17/bu...ewanted=1&_r=1 IOW, fewer people looking for work ---- "lower unemployment." |

How shall we interpret your comment? His post shows that he was in substantive agreement with you - that the protests were misguided, and NASA's design of RTGs for space was adequate. Simply because he dared to speculate in an aside that these protestors, ill-founded though their actions may have been, might still have at least provided the benefit of encouraging some small additional measure of caution on NASA's part... does _not_ mean he is supporting them, or trying to give to them the credit for NASA's efforts. This kind of overly vehement and overly ideological reaction only serves to make you look like an unreasonable person, excessively driven by politics, and thus diminishing your credibility. That is not the way to win the fight against those who want to tear down America. Moderates like J.F.K. made Americans aware of how evil Communism was; had it been left to Joe McCarthy and the John Birch Society, far too many people would have mistakenly thought Communism was just an imaginary bogeyman until it was too late.

Responsible people,at least those with common sense,generally know when the game is up after the wheels fall off a popular bandwagon but as so often happens,there are always some who insist on dancing long after the party is over,something like this - http://www.nature.com/nature/journal...l/468345a.html These people are concerned about defending their ideology that humans can control global temperatures rather than before 'climategate' where they were simply promoting it and dismissing everyone else.The reason this particular bandwagon emerged in the first place is mainly due to the lack of astronomers,at least astronomers worthy of the title insofar as humanity doesn't even have an accurate cause behind the temperature fluctuations between January and July due to an accurate assessment of the planetary dynamics behind this fluctuation hence there is little point trying to force conclusions based on minor temperature variations when the major fluctuations across latitudes have still to be sorted out. Too often readers get mangled by getting caught up in minutiae such as this attempt to force global temperatures through the prism of a minor atmospheric gas thereby losing the wider picture,the fact that climate has alway altered the biology and even the geological history of the planet as it is written down in rocks and fossil records and,in all respects, that is the most disappointing feature is all the hyperfuss over human influences on global temperature in that it would have short-circuited all other sciences in the process.For instance,had this carbon dioxide bandwagon kept rolling and they forced through the belief that humans can control temperature then what next ?,if the global temperature goes up,it would then be proposed that more needed to be done and if the global temperature dropped it would have be proposed that emission restrictions were working yet it would prohibit the investigation of any natural causes that actually influence global temperatures. After 'climategate' it is easier now to see just how large a bullet our race has dodged but the climate issue is only a small facet of a much bigger problem which the scam exposed and that is why many scientists are running scared,those scientists who live off modelling agendas which were once restricted to those who make a terrific living out of dumping toxic concepts into the astronomical arena and love nothing better than making big sweeping generalizations without fear of being challenged just got badly burned when they encounter actual science of experience where things are up close and personal.It is not climate that is the problem,it is the way science approaches natural phenomena in trying to model its way to a conclusion and that is why you will see many scientists now clamoring to dismiss the social agenda based on carbon dioxide,not for reasons that it is bad science but that it is bad for all scientists and the 'scientific method' where the real scam is. |

Tell us one empire that never fell, eventually. All empires/systems become lazy, corrupt, unequal and wasteful of resources. Because all of them have demanded a loyalty to something which offers little or nothing back. The investment in work or service should be reflected in the return on that investment. The firm connection between work or service and creature comforts is often broken or is never made. Where large numbers of the population are denied comfort and self respect from within the system then the system crumbles. You cannot build a long-lived empire on fear. Nor denial of return on investment for services rendered to the empire. Nor on obscene inequality. Nor on corruption. These always lead to an "alternative" economy as the lower orders seek a route to greater security and comfort levels denied to them within the system. They are merely copying their master's own corruption. So (for example) they deal in drugs instead of working for a minimum wage. Obvious unfairness is the destroyer of loyalty to any system and its rapid downfall. All empires (to date) have relied on inertia and fear of unfair sanction to survive. The more active investors in the system, all receiving sufficient interest, the greater the longevity of the system. This holds true from a sprawling nation right down to a small business. Respect breeds self respect which breeds willing volunteers. Pressed men carry the burden of the entire system on their shoulders without receiving adequate compensation for the load. This is extremely counter-productive and typical of dictatorships and communism. And poorly run businesses and nations. Productivity within any system is directly related to self respect. Self respect is built on trust and encouragement. Never on brain washing, fear and and propaganda. Only corrupt empires will deal with corrupt empires. This top heavy, mutual gain denies entire populations the freedom to make their nation (business or empire) wealthy. An empire is built on the broad foundation of the lower orders. If they cannot take the load then the entire edifice will sink beneath the waves. |
