  1. Re:Investments which outlast the investors... on Paul Krugman's 1978 Theory of Interstellar Trade · · Score: 2, Insightful

    Sure it's easy to estimate the value of an oak tree you plant today. All you have to do is estimate the price of the oak tree in 200 years, and the interest rate over that same period. Straightforward.

    Err, wait. Do you think there might be a risk of fire? You had better estimate that, as well, and discount the present value by the risk of it burning to the ground. And, I guess drought, as well, now that I think about it. Maybe disease. What if oaks become so rare that a future government nationalizes all oak stands as national historic sites, and imprisons the bourgeois, robber-baron, owners? Hmm, a lot of stuff could happen in 200 years. I assign the value of $0 to your seedling oak.

    Look on the bright side, though. Now you understand why interstellar trade has some difficult-to-solve economic problems.

  2. Re:Uh oh on FTP Hacking on the Rise · · Score: 4, Informative

    I think you may have misunderstood. RFC 114 refers to FTP, which is from the 70s. The poster was talking about scp, which is certainly from the mid-90s.

    Now, whether 1971 counts as disco-era is another question. I would say that it is pre-disco, since every school child knows that the disco era started with Soul Makossa in 1973.

    My father was concerned about personal information remaining on a dead hard drive. I told him to take it apart and heat the platters in his fireplace past the Curie point.

  9. Re:OK, I've gotta ask on New Catalyst May Be a Boost For Fuel Cells · · Score: 5, Informative

    Platinum is good at binding gas molecules to its surface (adsorbing them), which changes the nature of their electron clouds. This helps overcome the the van der Waals forces that hold them together or apart, making them more likely to react.

    Nobody knows for certain just why platinum is good at adsorbing gas molecules to its surface.

  11. Re:Archer was the first recorded to captain on Paramount Casts New James T. Kirk · · Score: 1

    Well, Jonathan Archer has artwork hanging in his cabin on board NX-01 that depicts an Enterprise that looks a lot like OV-101. If it is OV-101, that Enterprise was commanded by two people: Fred Haise and Joseph Henry Engle.

    It may not have been OV-101, though, because OV-101 was named after NCC-1701, which was built later than NX-01. If it was OV-101, then Archer would have had some foreknowledge of NCC-1701. At the very least he would have known the name of the ship. Or maybe, in the Star Trek universe, Star Trek is so popular that humanity models its entire space program after it, rather than just using it to name spacecraft.

  13. Re:Missing information in story on Future Looks Bright for Large Scale Solar Farms · · Score: 1

    I don't really know the answer for sure, but you can make a back-of-the-envelope estimate:

    The article says that the sun imparts 8 kilowatt-hours of energy on a square meter of the Earth's surface every day in the American Southwest. I'll assume that the 64 megawatts are generated continuously. This is probably not a bad assumption, because the article says that the power is used to light Las Vegas, so it seems likely that it is generated at night as well as during the day. They also talk about how they store the heat. This means that the plant generates 1536 (=24*64) megawatt-hours of electrical energy every day.

    The article says that the plant heats water to 280 celsius, which is 553K. It probably releases water vapour on the cold side, which is 373K. A carnot engine running between those temperatures would have an efficiency of 32.5% (=1-373/553), which is an upper bound on the efficiency of the plant. To make the math easy, we'll pretend that the plant is 20% efficient at converting sunlight into electricity, so you need 5 square meters of land to generate 8 kilowatt-hours of energy per day (0.008 megawatt-hours). This means you need 960,000 square meters (=1536*5/0.008). Google calculator tells me that this is about 250 acres.

    It's also worthwhile to point out that Jatropha is nitrogen fixing. As long as the plant can be removed (the "weed" part gives me pause), this could be a money-making fallow crop, with the later crop using the nitrogen "fertilizer" left behind by the Jatropha.

  19. Re:Global Warming Absorber on Solar Power Headed For 45% Annual Growth · · Score: 1

    A handwaving argument based on conservation of energy and positive entropy shows that any light not reflected by the Earth's surface winds up as heat in the end. The less reflective the surface of the Earth, the warmer it needs to be to radiate the energy. Therefore, if PV cells are more absorptive than the land or water they cover, they will raise the Earth's temperature. I estimate that the effect is small.

    Here are some decade-old numbers comparing per capita spending on health care. The United States wins, hands down. I think this is still true.

    Near the bottom of this page, there are two graphs that show life expectancy vs. per capita health care spending. The United States does not win; not at all. This does not necessarily mean that Americans are being taken to the cleaners when they go to the doctor, though. It may mean that an unhealthy lifestyle is covered up by enormous spending on doctors and pills. Frankly, I think it's probably a bit of both.

    I saved a Nokia 6310i in a similar way. The power button ceases to function that phone when it's wet, so get the battery off as fast as possible. I dropped mine in a pond, so I rinsed in thoroughly when I got it home, banged it out on my hand as well as I could, and then dried it using a hair dryer on the "cold" setting. There are enough holes in most electronic equipment that the airflow from the hair dryer can swirl around in there. The dishtowel centrifuge is a stroke of genius, though.

    The phone still works 18 months later.
