Progenitor of the Weird Knife Wednesday feature column. Is “column” the right word? Anyway, apparently I also coined the Very Specific Object nomenclature now sporadically used in the 3D printing community. Yeah, that was me. This must be how Cory Doctorow feels all the time these days.

  • You’re conflating the tuner with the antenna. The person you replied to, however, is correct including the comment about the digital tuner boxes (which convert to an analog signal for old TV’s) being available for free during the analog to digital changeover back when.

    Any piece of metal will work as an antenna, even for receiving digital broadcasts. It might not work well, but there is no magical difference between a “digital” antenna and an “analog” one, and since digital television is transmitted over pretty much the same original frequencies as analog was, old analog antennae are already quite well tuned in size and shape to pick up modern digital signals.

    You just have to plug your 1940’s antenna into a 2009+ or so television. The antenna itself doesn’t “decode” anything. It just catches radio waves and passes the waveform along to the TV or tuner box. I still use the old 60’s era rooftop antenna that cane with my house, but plugged into my modern TV and it receives digital channels just fine.






  • The other thing is, both towers were plane impact resistant. Both of them took dead square hits from airliners and remained resolutely standing afterwards. What it turned out they were not proof against was an ongoing raging inferno inside that was hot enough and carried on long enough to weaken their critical structural elements.

    If the planes had not been laden with fuel and/or if it had not ignited for whatever reason, the towers probably would not have collapsed. They probably wouldn’t have been readily repairable, though, so then the question would be what to do with two massive skyscrapers with giant holes in the middle of them. They’d probably have to be demolished eventually anyway. Said demolition would have killed far fewer people.




  • Agreed. And Kefka was way cooler anyway.

    (I firmly believe most people gush over FF7 so much only because it was their first exposure to a mainstream console RPG in non-Japanese circles. FF7 as a whole was a fairly meh entry into the series anyway, if you ask me.)

    Not only did Kefka have real style, twisted though it may be, he also for all intents and purposes actually managed to win. He fractured the world, scattered the heroes, built his goddamned tower, and was lording it all over everybody with a penthouse view. He didn’t have angst; he was just nuts. It was frankly a complete fluke that he got the shit whacked out of him by a little girl with a paintbrush, a 8x per round attacking Moogle with Genji gloves, a senior citizen, and a mime.




  • FYI, there is no “better” way to use hydrogen that will result in extracting more energy from it than it physically contains and can be released via oxidation. This is not a matter of “development” or “breakthroughs.” It is physically impossible. The standard enthalpy change of combustion of hydrogen is 141.83 MJ/kg. Period. That’s it. That’s all you can ever get out of it, provided you achieve perfect efficiency (which currently we don’t). Ongoing research is surely working on getting is closer to 100% efficiency, but it will never get past it. You can’t defy the laws of physics.

    Insofar as I am aware all current hydrogen vehicles already use fuel cells to generate electricity and use that to drive electric motors for motive power. No one is burning hydrogen in a combustion engine in vehicular applications. There are some power plants that are doing it, though, mostly as a mechanism for storing and later reusing excess energy generated from other sources. You can go cross-eyed reading up on it here, if you are so inclined.

    There is the notion of the “hydrogen economy” floating around, that is the use of hydrogen as an energy storage and carrying medium – not, notably, as a fuel for actual generation of energy – but it’s pretty certain that outside of some limited applications this will always be a worse deal than just taking the energy in the form of electricity and putting it in a wire.
