    So whats my point? Me, a lifelong geek, no longer gives a flying rats ass about the future of "digital media". I'll keep my analog cable, FM radio, and CD player for as long as they continue to work.

    But that's the problem, isn't it? Congress has mandated the sunset of analog radio and TV. I watch so little TV it seems a shame to spend any money on a new one, but in a couple of years (who knows when, exactly) my set is gonna stop working when they stop broadcasting analog. I don't want to spend gobs of money and I don't want to get stuck with another Betamax. Hopefully the FCC will get its act together enough that I can buy something that lasts a few years.

    The thing that really pisses me off is it seems none of the broadcasters is really interested in high definition. They want digital so they can cram more channels into the same band. So I'm gonna trade my analog set for a lower quality digital picture and the choice of 10 reality shows instead of 5. Great.

    While I recognize that the STS has issues, most of which stem from politics, it's very important to note that anything that replaces the STS, be it the CXV or something else, won't really be any safer.

    I think you could pretty convincingly make the point a vertical stack is much safer than the STS design. A vertical stack would definitely have prevented the Columbia's destruction and would have given Challenger a fighting chance.

    Then Jerry Pournelle is an idiot.

    Rei, Jerry Pournelle is most decidedly not an idiot. He's been at this space stuff a long time, and not just in SF. If you're interested in a practical (operational) strategy for CATS, read Getting To Space and The SSX Concept. You may not agree with everything, but I've read enough of your posts to believe you'll agree with most of it, or at least acknowledge the possibilities.

    Orbital Sciences Corp would get 2 billion dollars just for strapping a heat shield to one of their Pegasus rockets instead of a payload - congrats we just wasted 1/3 of a CEV's development cost to accomplish nothing. Or did you not already know that private companies, using private funds, have already launched orbital rockets? It's not a very profitable business - that's why there aren't too many companies doing it.

    I'm not sure you read the prize specification as intended. By "spacecraft" he's not talking about a missile, but rather a manned ship. Also, assuming you weren't talking about manned craft, if you attached a heat shield to Pegasus you're still a long way from having a spaceship you can land and reuse in two weeks. I don't think two billion dollars is out of line for a manned, reusable, orbital spacecraft. We don't have the capability, and given the past history of NASA projects, you're making quite an assumption to say 2 billion is 1/3 of CEV's development. It'll probably end up being more like 1/20th. The great thing about a prize-type contract is it doesn't cost anything if they don't deliver, and it never goes over budget.

    Number 3 would never be done without subsidy. The costs are way off. I can do a breakdown if you'd like on what construction and supply costs would be during that period.

    Well then, it wouldn't cost anything to put the prize out there, would it? Even if you and I can't see a way to do it, perhaps it could still be done. I'm not convinced it's impossible if the emphasis was on operational costs.

    Number 4 makes no sense - why offer a prize for a *specific* clean power technology? The numbers are also way off on this one. Here, do the math: 1,367 W/m^2 (optimal), 35% conversion efficiency (very good), 5% beaming efficiency (far better than currently available). 800MW = 334 million square meters. Assuming 0.1 kg per square meter (light for high efficiency cells), that's 34 million kilograms (ignoring support eq., such as heliostats, orbit correction, transmission, etc). At a launch price of 7,000$/kg (cheap), that's 233 billion dollars.

    The reason for having a specific technology is the power generating capability is only half the goal. The other half is to develop an infrastructure for cheap access to space. There's no reason to assume launch costs of $7000/kg. Yes, that's cheap today because every mission is a one-off. Think about this, though: If the prizes were done in order, you would conceivably have a reusable spacecraft before you went to tackle this one. There's no reason I can see you couldn't build an SSTO craft which could be flown often enough that the major component of the operational cost was fuel.

    It's possible you could only get the cost down to $6999/kg, in which case you're right, the numbers won't work. The reality is we just don't know what could be done because nobody's tried it. Fuel is you're only absolute operational cost - the others could conceivably be attacked with great success under the right conditions.

    Also, the prize doesn't specify the power station would have to be turned over to the government. So as a potential investor it wouldn't be out of line to consider the post-prize profit from power generation.

    p.s. What the hell is a "duelist of Dios?"

    Sorry. I was so used to people coming back with something like "It really is prohibition if there's no money..." I jumped the gun trying to forestall it.

    Wouldn't it be better, if you prefer to have the research conducted in an ethical or responsible manner, to have it advanced in a nation where you have a legal and fiscal framework to control it?

    If we put any limits on research at all the temptation will be to move to China. I don't understand how we can have a "legal and fiscal framework to control it" without having restrictions on what can be done. The stem cell stuff is childs play compared to what's being contemplated - if that's enough to send it offshore we can give up on having any control at all.

    You lost the argument. Nothing I have written advocates doing research with the brutal ends that the Nazis advanced.

    I didn't mean to imply that you had. I was just trying to say the ethics of the research are really independent of the promised benefits (except in really very rare circumstances that don't apply here).

    Now that Bush has made the political (rather than scientific) decision to limit stem cell lines, this activity will most certainly occur outside of the US and beyond any jurisdiction of American ethics organizations.

    Of course it's political. Science only answers "what can be done?", not "what should be done?" I don't have any problem with the idea there should be limits on what my tax dollars pay for. In any event, Bush doesn't have the power to unilaterally make stem cell research illegal, he just changed the rules under which scientists get money for the research. And no, that's a long way from a prohibition.

    Furthermore, the argument that we should allow something unethical to happen in the US so it doesn't happen somewhere else is specious. The Nazis conducted numerous medical experiments on people. Should we have done the same so as not to fall behind?

    Rails are more fuel efficent for moving freight than paying tons of money on an interstate highway system, and then have 16 wheelers burn all that diesel without significantly subsidizing the roadway. If the rails were more robust in operation, instead of truckers driving across the country, they could move freight from major rail stops, and cut down on the interstate driving. In NYC alone, getting a freight line into Long Island would significantly reduce the volume of trucks across the bridges & highways.

    You're mixing apples and oranges. There's no reason freight needs to be high speed. What you're arguing is a more efficient version of the freight system we have already. I'm not a train expert, but I'm pretty sure the freight companies (which aren't government agencies) are operating as efficiently as they can. If the freight line doesn't go to Long Island it's probably not worth the money.

    The reason why this will not happen in the near future is threefold. 1) The stupidity (psychology) of the average American citizen (SUV driver). 2) Special interests such as the airlines and trucking industry, and 3) politicians.

    That's pretty cynical. I think the real problem is some of the negative impacts from cars aren't paid for by the drivers - pollution, noise, etc.

    Here in the San Francisco bay area we have a great light rail system called BART. It's high on my list of reasons to be here. But financially it's a loser - taxpayers at various levels are subsidizing the system, because if they didn't nobody could afford a ticket.

    Now, normally, as a libertarianish kinda person I abhor the government subsidizing individuals' voluntary activities through tax money. But in this case you could make the argument cars would be much more expensive if drivers actually paid all the costs associated with their driving, so the train subsidy balances the ledger.

    Passenger rail could easily be cost effective.

    It always is, on paper, but somehow when they actually build it only areas with extremely high density can support a self-sustaining rail service. I think passenger rail would have a hard time competing even in Europe if gas taxes weren't prohibitively high.

    But the "consent" argument is pretty slippery, as in "halfway down the slippery slope". If it's OK for two men to get married because it's consentual, why isn't it OK for twenty? One hundred? Clearly not all consentual unions are "marriages". Traditionalists want to draw the line at a man and a woman, and clearly you would like to see it expanded to include two men or two women. But where do you say it ends, and why?

    Let's say a brother and sister want to get married. Now, traditionally this is frowned upon, not just because most people find it icky, but also it's not a good idea for two closely related people to have children. Under the "consent" logic, I suppose it's OK as long as one of them is sterile. And what about a man and his brother? His son?

    Even people who support gay marriage start to squirm here, but if one responds "it's all good," then at least it's logically consistent (if impractical. Would a company be required to put 20 people on the health plan as a result of one new hire?). But that's not what I usually hear.

    The response I always get when I ask this question is "well, it's not about that. It's about two unrelated people that love each other." Maybe so. But surely laws must be based on logic at some level. Where is the logical endpoint of this argument? If the response is "it stops at two people because that's the way it is" then you don't have a response to people who say marriage should be only for heterosexuals because "that's the way it is".

    By the way, I'm not against gay marriage, provided it's done at the state level through state legislatures. But there are some logical inconsistencies that need to be resolved for me before this is a "civil rights" issue to be addressed by federal law or (especially) courts.
