    cooping it up as you go along means taking in air that was initially at rest and getting to move at the speed the engine is currently going.

    One quibble:

    Actually, the whole idea of the scramjet is that you don't boost the air up to the speed the engine is currently going. You burn the fuel in the air as it passes through the engine at supersonic speed. That's the "SC" in Supersonic Combustion Ramjet.

    There are, of course, lots of practical difficulties; you listed some of them.

    Gee, that's not what all the Anthropogenic Global Warming alarmists were saying in 2005. They were all shrieking "SEE! SEE!!! It's all George Bush's fault for not signing Kyoto!!!"

    Every time there's a heat wave, the cries are "There it is!! *PROOF*!!!!"

    When it's followed by a cold snap, it's "um, mumble mumble mumble".

    The rule seems to be that any single year which fits the agenda is "Obviously A Trend." Any single year which fails to fit the agenda is "Well, a single year does not make a trend."

    Though there's also the experience of a guy I knew in college in Alabama back in the late 70s -- An African-American man with a white wife, working as a systems administrator in the campus computer center. He moved to a "oh-so-very-superior-pat-ourselves-on-the-back-for -being-so-very-tolerant-and-progressive" part of the country. He moved back to Alabama. He said that the percentage of racists and bigots was no less in the self-proclaimed "progressive" parts of the country. The racists and bigots there, though, would smile to your face and shake your hand, then knife you in the back when you least expected it. He said in Alabama, where the same percentage of bigots were up-front about it, they could be avoided. The majority who were friendly and shook your hand were being honest.

  5. Why not use an aluminum-air battery? on Aluminum Alloy Releases Hydrogen From Water · · Score: 1

    This whole process seems unnecessarily complex to me. React aluminum with water to get hydrogen to run in a IC engine or fuel cell? If you're going to run the hydrogen in a fuel cell, what does this process do that makes it better than an aluminum-air battery? That seems to be a simpler and more direct use of the energy you get from oxidizing aluminum. I would think it would be more energy efficient.

    I don't know about gas prices in the U.S. "being held artificially low". A good chunk of what you pay at the pump is gasoline taxes, plus sales taxes on the gas taxes. Rather, in many other countries, the gas taxes are much higher. Just try to get someone elected on a platform of adding several dollars per gallon of gas taxes. Or getting them re-elected if they ever try it.

    That said, by "years to recoup investment in a hybrid" standards, current hybrids aren't a good investment. But I'd like to see them do well, because once a market in hybrids and pure electric vehicles is established, it's very likely to lead to vehicles which do make direct economic sense.

    But it is not legal, when you buy Girl Scout cookies, to deduct the price as a contribution. Fees for goods or services are never tax deductible. You can't get around this by calling it a "contribution" if it's a fixed "contribution" for a particular good or service.

    Unless you're a Scientologist.

    This is the very ultra special tax break that Scientology members get - Fees for auditing, to the tune of (last I heard) $700/hour or so, are fully and completely tax deductible, in spite of a Supreme Court ruling that they were not. The IRS overruled the Supreme Court and said Scientology auditing fees were fully deductible in 1993.

    Now, you may well ask, how come the IRS has the authority to overrule the Supreme Court? That is an extremely good question that I would really, really love to see answered.

  11. Re:Which is why India's looking at thorium... on The Coming Uranium Crisis · · Score: 5, Insightful
    Absolutely. According to my copy of the CRC Handbook of Chemistry and Physics, "There is probably more available energy in the Earth's crust from thorium than from uranium and all fossil fuels put together." But even short of that:
    1. The cost the uranium fuel is a relatively tiny part of the cost of nuclear power. Double, triple, quadruple the price, and it's not going to make a huge difference. There's a whole lot of energy in a little bit of uranium.

    2. The "shortage" is, more than anything else, an artifact of failure to reprocess wastes. Fuel rods have to be replaced, not because all the U235 has been fissioned, but because neutron-absorbing fission products have built up and started getting in the way. Only part of the fissile isotopes in the fuel is fissioned before the fuel rod has to be removed.

      Reprocess, separate out the fission products, and put the remaining U238, U235, plutonium, and other actinides into new fuel rods, and available fuel expands by several times. This is before you even start thinking about breeder reactors.

    3. Breeder reactors.

    4. Back in the 1970s, the Japanese demonstrated a process to extract uranium from sea water using an ion exchange process, at a cost of about $200/pound in 1970 dollars. That could be considered a very long term ceiling on the price of uranium.

Similar to how the Andromeda crew react when a Vedran puts in an appearance.

    Yeah, yeah, yeah... Andromeda, the series, in spite of a really nifty background, was wildly uneven. For every really good episode, there was at least one unspeakably putrid episode. And that was the first year -- Jerkules and the suits soon fired everyone with a brain and destroyed everything good about the series, and "unspeakably putrid" became top end of the Bell curve. I didn't watch any of the fourth and final season, but all accounts are it got even worse. Worse than the third season, it'd have to be getting into "brains running out your ears, spork your eyes out just to make it stop" territory.

    Student has a class assignment in FORTRAN, has the whole program punched up on cards, but when he runs the deck, he gets a nice compile listing, no diagnostics, except at the end, it says "NO PROGRAM", and exits.

    He takes his deck and listing to Use{r|less} Services, where the usual suspects mull over his listing for half the day trying to figure out what in the world was going on. They see obvious CS101 novice type syntax errors which should have provoked nastygrams from the compiler, but the compiler just happily chugged through them with no diagnostic.

    Someone notices that the addresses in the right hand column are all zero. No code is being generated. (This compiler, in its output listing, printed the address of the generated code for each line as a debugging aid. Obviously, it's not doing any optimization.)

    Finally, they give up and hand it to the resident person who really knew this stuff. He looked at the listing, said "Hand me the deck." They did, he looked at it, punched a card to read it into a file, did a quick text edit on the file, punched the file, and threw the original away.

    When the deck he punched ran, there was the same listing, but with all the diagnostics for the syntax errors.

    The first line of the FORTRAN program was a comment.
