    Challenger wasn't alone. Columbia failed due to NASA overconfidence.

    Since you made the suggestion, I thought I'd point out that Orbital used refurbished Soviet AJ-26 (N-33) engines.

    OK, so they found hydrogen sulfide, ammonia, hydrogen cyanide, water vapor, carbon dioxide, methanol, formaldehyde, and sulfur dioxide. Why the cute description? lowest common denominator? Trying to put it into perspective of average life experiences?

  4. industrial computers on Ask Slashdot: How Do I Make a High-Spec PC Waterproof? · · Score: 2

    You're going to have a hard time finding a high spec computer that meets your needs, because of the cooling requirement. If I were you, I'd look to industrial enclosures designed for water proof operation. (there are industrial computer enclosures) Make the system water cooled so that you can run cooling lines outside the enclosure and use an external pump and radiator; this will allow you to minimize the size of the enclosure containing the computer. You'll have to accommodate the VRMs and Southbridge, which are typically passively air cooled (but do require cooling). You might try taping off connectors and spraying the PCB with conformal coating, to reduce the damage should water get into the enclosure. Connectors can be filled with dielectric grease on the pin entry side and epoxy on the wire side to prevent water access there.

    I have never tried to do this with a computer; although, the techniques above have been used by me in other applications.

  5. Tech labor on Tech Firm Fined For Paying Imported Workers $1.21 Per Hour · · Score: 4, Insightful

    So... if they can get away with doing this for tech labor, that means my company can bring 10-20 engineers from our China site to work in the U.S. We can pay them their current wage (no adjustments necessary) and only risk a trivial slap on the wrist if we get caught. This is a win-win. What a great precedent they've set here.

    So, you go to an event in the desert, and you expect to be able to buy ice? Why are you depending on ice in the first place. WTF people? It's hot and it's dry; that's why it's called a desert for fuck's sake. Learn a little independence and self reliance.

    I'm not disagreeing with you in principle; but, the driver signing issue isn't Microsoft's. It's the hardware vendor's fault. Microsoft's generic drivers come with the OS they're written for.

  10. Re:5 minute charge on Battery Breakthrough: Researchers Claim 70% Charge In 2 Minutes, 20-Year Life · · Score: 1

    6,000 amps at 120VDC could be generated from a 12,5kV feeder found in a typical commercial setting; so, no, you don't really need a "direct connection to a power plant". I was exaggerating a bit. I would expect the utility to pitch a fit if you said you were going to pull that much power... They might have a choice words about your 3/4 megawatt load that switches in for 5 minutes at a time. Words like, "No"

    I'm sorry, that's only 17 kWh over an hour, 1.4kWh in 5 minutes. To get 60kWh charge in 5 minutes you have to 60,000Whr / 120V * 60min/hour / 5min = 6,000 Amps.

    Fair enough, nearby supernova == bad. Nuclear is often classed as a renewable because so little of the U-235 is used (1% or less in a typical commercial power reactor) -- the fuel can be recycled, reprocessed and re-used. Then there are breeder cycles....

    Clearly, they're practicing some sort of black magic if they think they can charge a 60 or 85 kWh battery in 5 minutes. Either that or they have a connection directly to the power plant located just around the corner.

    we're building more aircraft carriers because they have to be replaced. Enterprise was just retired after 50 years and is being decommissioned. The Kitty Hawk class are all retired now. Nimitz is 42 years old -- yes, its keel was laid in 1968 and it entered service in 1972. It takes 4-5 years to build one of these floating cities. There may be 10 of them (not counting Enterprise and Ford); but, one is usually in the yard being refit (15 year overhaul cycle -- Lincoln is currently in the yard) and there are several in port at any time. It takes 10-12 of them to support Naval operations worldwide. The rest of the world has basically stopped using aircraft carriers, because they're expensive. The U.S. uses them for force projection and as a platform for operations of all types, including disaster relief. Oh, and aircraft carriers run on renewable energy -- they have a pair of nuclear reactors in the hull.

    This, with artificial implantation and genetic engineering, brings us one step closer to asexual reproduction. It won't be long before science is able to pair DNA from two women to create a new offspring. Artificial wombs will follow. Soon women won't need men any more. Then the male geeks will go from having had a limited chance, to having zero hope of ever meeting a woman and having sex.

  19. Re:Just Go Nuclear and Get There Quick on NASA Eyes Crew Deep Sleep Option For Mars Mission · · Score: 1

    I know VASIMR isn't a nuclear rocket (although at some field densities with the right fuels and energy input, the math shows there is the potential for limited amounts of fusion). VASIMR engines of that size will require a nuclear plant to power them. -- and I'm not talking about RTG's here. Frankly, this is territory we've not explored really, beyond a few early ground tests and small scale (10kW) fission reactors launched in the '60's and '70's (SNAP, RORSATs, Topaz) which mostly used thermoelectric conversion. That's not going to work for a 10MWe plant,

  20. Re:Just Go Nuclear and Get There Quick on NASA Eyes Crew Deep Sleep Option For Mars Mission · · Score: 1

    I was politely trying to say that it was written by the company Ad Astra Rocket Company and they have an interest in promoting VASIMR. Yes the math is straight forward and I believe the technology works. However, I have seen (and worked for) companies that will write white papers that put everything in the most favorable light, even if the result is optimistic, and frankly not realistic. Overstating efficiencies, for example, by using the best case numbers observed in the R&D lab, and not the real-world numbers obtained from field trials. So, yes, such "groups" really exist.

    You're just lacking in imagination is all. Of course, Earth's big advantage is having this stuff called "air", which contains this stuff called "oxygen". Otherwise, (besides Mars being smaller and colder and having no magnetic field) they're pretty similar.
