    bottom there was a large, but still finite waste chamber.

    This got me to thinking - The major expense of anything in space is pretty much launching it. Storage space is essentially unlimited as long as you're willing to put it outside.

    Rather than bringing stuff back, store it up there until you have a use for it. Some recycling tech, even if it ends up limited to making extra shielding, would be good.

  2. FlexFuel... Non-Optimal... on Fuel Tanks Made of Corncob Waste · · Score: 1

    Right now, they are probably statically tuned to get more out of Gas, and not so much E85

    Logically they'd have to be. Set the compression low enough for standard dino-gas and you burn ethanol inefficiently. Set the compression more for alcohol and you cause detonation, which will damage the engine. Which situation is worse? Thus - they tune it rather heavily to gasoline. Still, Josquint might have something wrong or poorly designed in his vehicle, as every review I've heard of has lower milage with E85 but MORE power.

    My mid-term idea for a solution: Have adjustable timing and set the compression fairly high. Require the user, if he's to use dino-fuel, to use premium(or visit the local airport).

    Simple enough, though it generally requires a warrent.

    All blocks of IP addresses are owned by somebody, mostly ISPs.

    Once you have an IP address, you look up who owns it and you call them. They do their research, looking at things such as DNS records, DHCP assignments, DSLAM logs, etc... They then look up which customer that was, and there you go.

    In a corporate enviroment a simply DNS lookup should give you a computer name, a little more the switchport it's connected to, and a little digging who's logged into it.

    I wasn't talking about CFLs, I was refering to actual fluorescent bulbs designed to go into a fixture with a seperate ballast.

    Yeah, CFLs are only good for 5 years, and they're less efficient and more expensive for any given amount of light.

    Good bulbs/ballasts tend to cost 50-100% more, but can easily be worth it. The bulbs went from $3 to $5.50. For 20k hours, I figure that's not much. The better quality ones produce more light for the wattage, and light with better color(in the 90's). The better ballasts start quicker, especially at cold temperatures, maintain the bulbs in better condition, and don't hum(perceptably). I think those were 50% more, but I ended up replacing the fixture rather than the ballast. More expensive, but the old one was nasty and had a wierd ballast (it was a three bulb model).

    That's funny. As I've stated, mine come on instantly, yet I've had some of them for as long as 5 years without problems. It was an attrition replacement scheme.

    Still, the 'junk' ones, even if they don't last as long, will be useful in areas that you need instant light, yet not high traffic.

    Good idea on marking the install date. I should probably do that.

    Hmm... Just pulled out one of mine. it's a GE Helical 20W unit, designed for 120VAC/60Hz/300mA operation. Model FLE 20HT32SW. It's good down to -15C, has a color temperature of 2700K and a CRI of 82*. They're $15/6 at walmart.

    Of course, Japan tends to be far more expensive than the USA, though the difference in Hz and voltage shouldn't make a huge difference, unless they're just rebranded bulbs meant for 120VAC. The electronic ballasts are like switched power supplies; They multiply the frequency of the AC(into the 10's of kHz) in order to make transforming the voltage easier and more efficient in a small package, even then, the 10hz difference is nothing. Not being able to read japanese, I can't compare with the ones on the site you posted. I do remember reading somewhere that the helicals are the best, but have no source.

    *The tubes I just installed might be a shade whiter, their CRI is over 90(shouldn't have thrown the tabs with the info away).

    My newer bulbs ( 3 years old) all come on quickly enough that I can't perceive a warm-up time. Now, admittably I haven't tested them outside in -30. But that could be considered a specialty application.

    The 4 tube fixture I installed is rated to 0F as 'instant start'. And it is an instant start. Off, on, with no perceptable increase in light once it's on.

    I'm apparantly not one of the more sensitive people on the board - but I can spot a failing ballast at 50 paces. The flickering drives me bonkers in short order.

    Part of the problem you can have in many government/school/business/industry buildings lit by flourescent light is that they use the cheapest components they can get their hands on. That means lousy bulbs and ballasts. They probably hadn't been replaced when they should have either.

    I went through an upgrade in one building where they finally went through and replaced all the ballasts and bulbs - difference was like night and day.

    Uh, Did you get your CFLs at a flea market or garage sale? I run nothing but CFLs and FLs. I just replaced an old flourescent light fixture(cheaper than replacing the ballast, as it had a wierd one) with a new electronic ballast one. The old one took a minute to start, but was built back in the '60s. The new on advertised: No hum, instant start down to 0F. Haven't tested the cold start yet, but it's on effectivly instantly. Same with my CFLs. If yours are taking a long time to start up, either something's wrong with your power or they're the old type with magnetic ballasts. The new electronic ones get rid of hum/flicker, as well as start very quickly.

    Of course, CFLs come as one unit, and 'only' last 10k hours on average vs 20k for straight bulb FL, and even longer for the ballast.

    Premium fluorescent tubes are ~$5.50 each. Cheap ones are ~$2.50. A cheap 4 pack of incandescents will cost ~$.50.

    Determining the meaning of Privacy is also another good example of judges interpreting what isn't literally written.

    The problem with interpreting this loosly is you also get decisions like Kelo v. City of New London. I'm sorry, but judges getting creative in their interpretations is a band-aid, not a fix. The fix is to fix the problem in the law or constitution.

    For controlling the police - Maybe a citizen's review board. Each year all the local officer's records are reviewed and they're rewarded if they've done good, and punished/fined/fired if they've done bad.

    Increased bandwidth requirements are driving utilization of spread-spectrum technology such as DSSS, FHSS, and OFDM instead of single-band transmissions. These transmissions are extremely hard to detect, looking much like random noise, especially if you don't know exactly what you're looking for. They also allow the transmission of more data with less gain, allowing the usage of lower transmission levels, making detection at distance pretty much impossible.
