    After all, are you going to tell me you can't use waste heat from the ICE to heat up some water?

    Interesting reminder, in context. Waste heat from an ICE might be easier to tap if you used a low pressure (as in near-vacuum) closed cycle medium. Easier to build steam from liquid in near-vacuum, and easier to liquify with an ambient heat sink. Would that be capable of doing any work though?

    ...whereas, in the USA you have to *pay* the cable companies to transmit advertisements, interspersed with crap "Reality TV" filler, into your home.

    There's an alternative. Three years ago my daughters told me that everything on TV, both cable and free-to-air, was crap. They found the repetition of even half-decent material was annoying and if we wanted a video they'd be happy to wait until we could find the DVD. So I pulled the plug on it and sent the cable modem back to the carrier. We are happily without cable or free-to-air TV and none of us have missed it at all in the last three years. We've got the Internet, video rental stores and cheap good DVD's at the supermarket. "Downside" (heh) is the strange looks we get when we say "sorry, we haven't seen it" in conversations with others.

  12. Re:Crossbow Strength on The LCD Panel vs. The Crossbow · · Score: 1
    Actually, the medieval crossbows were quite strong, and were designed to go easily through the 16 to 20 gauge mild steel plate the knights and men-at-arms used at the time. A mere 30 lb longbow at 28" draw would go through 20 gauge mild steel with a field point pretty easily too, I know this from tests I've done. But to compare the SCA crossbow used vs a medieval crossbow with it's hand-crank winch to cock the prod and 3/4" diameter steel bolts, well, not much similarity there. You'd probably be better off comparing the medieval crossbow to a fairly large bore pistol, say 357 mag with target loads.

    SCA crossbows (at least here in Lochac) are designed not to hurt. They're pretty gentle things. I know this because I wrote the proposal to get the Victorian group on the police registry of legal sports users back when I was on the OziBoD. Did the research, documented our modern application and we restricted use to equivalent of a 30 pound draw longbow. With an SCA rubber blunted bolt instead of the um, somewhat malleable bolts shown by our Ukranian friends you might raise a bruise in re-enactment combat, just. No real physical damage to the armoured loons on the field.

    I suspect a proper 250 lb prod crossbow with a period broadhead bolt would do serious damage to whatever was on the other side of that display.

    Impressed with the display, though -- the hammer example was really cool.

    I always did wonder how much that I heard in that spa was real and how much was due to the invention of beer. The slow S-turns I heard, the too hot to refuel I heard too, as well as that scrap of dialog. It was back in 1979 or so that I heard it, so some details may have been missed or glossed over. Apologies for any inaccuracies, but *dang* what an aircraft.

    I used to work over at Moffat, during the Pioneer Venus days. I remember a NASA U-2 doing that same trick wrt. vertical take off. It just rolled a little ways down the runway, rotated, and headed straight up. I remember you could hear it long after you lost the visual.

    Problem was that they didn't have a material that could seal the tank and still be flexible while not melting off at those high temperatures. Have they solved this problem?

    One of the problems they had was dissimilar metals in the airstream, mostly for sensors and plugs -- they had different rates of thermal expansion than the skin. Things that leaked and didn't fit on the ground were designed to fit together quite well at rated speed.

    Heat was definitely a problem. There was at least one reported case where a pilot inadvertently got his helmet welded to the canopy in flight. And while sitting in the spa at the Jokewood in Mountain View a few years back I heard a story of a KC135Q refueling officer having to wait while the SR71 made slow S-turns to keep from stalling, while the skin of the aircraft changed from strawberry red to black. Too hot to refuel until he did.

    "Turn your ECM off please, I can't see you". "ECM is off. You will acquire visual prior to radar".

    Dang what an aircraft. Remember we had this before LBJ outed it in front of Congress. And word had it that one pilot said if they ever needed to break the record again, all they needed was to move the throttle up another notch.

    The 730 came after the 750 if I remember correctly, by a year or two. I think it was crippled in other ways, not just clock speed. I think chronology went - 780, 782, 750, 785, 8000-series, 6000 series, Microvax, 4000 series, with Alpha introduced in parallel sometime after 8000 series. I honestly can't remember where the 730 came in (may have been just after Microvax). Model numbers obviously had little truck with chronology, though. And the 750 was a good little calculator, given the tools of the time -- if you ignore the tape casette used for boot media, which was was rated somewhere around 1k / calendar month in throughput.

    My funny RAMAC story goes back to Scientific Data Systems in 1969. One of the rare and precious RAMAC disk units was in the Inglewood shop for repair. A gentleman from a sub-Himalayan country had been hired because of his educational quals, which looked very good on paper - PhD in electrical engineering or something equally credible. His boss carefully explained that this unit was the only spare one they had for NASA DSN (which worked on SDS 920's iirc. If any of you can explain "^G^GERR in context you get my next mod point) and that it was very precious. Then he gave him the job of cleaning the disks.

    A couple hours later he was found with a large bottle of MEK (Methyl-Ethyl Ketone, a popular cleaner at the time) and a packet of 0000 steel wool. The top three disks were very shiny, he'd gotten all that brown crap off them.

    First person I ever heard fired on an intake of breath.

    For comparison, the Vax 750 ran at 600Khz. K, not M. The 780 ran at 1MIP.

    There was an urge at the time to rate computers as nMVax, i.e. multiples of 1 Millivax. This in turn was based on the MilliHelen, the amount of beauty required to launch 1 ship.
