  1. Re:Orbital mechanics on Mars Had an Ancient Impact Like Earth · · Score: 3, Informative

    Unlikely. Pluto's orbit doesn't come close to intersecting with that of Mars, and circularizing a Pluto-sized object's orbit after the huge Mars collision event would require ... another huge collision event. [Un]fortunately, most of the debris in the Sol system has been cleared out by the current set of planets, so most of this stuff will remain speculation because the evidence is gone by now.

  2. Re:Impact Scale on Mars Had an Ancient Impact Like Earth · · Score: 4, Informative
    A related article over at SpaceFlightNow indicates that the researchers were specifically looking for a scenario that wouldn't vaporize Mars. And I quote:

    "We set out to show that it's possible to make a big hole without melting the majority of the surface of Mars," Aharonson says. The team modeled a range of projectile parameters that could yield a cavity the size and ellipticity of the Mars lowlands without melting the whole planet or making a crater rim.

    After cranking 500 simulations combining various energies, velocities, and impact angles through the GPS division's Beowulf-class computer cluster CITerra, the researchers narrowed in on a "sweet spot"--a range of single-impact parameters that would make exactly the type of crater found on Mars. Although a large impact had been suggested (and discounted) in the past, Aharonson says, computers weren't fast enough to run the models. "The ability to search for parameters that allow an impact compatible with observations is enabled by the dedicated machine at Caltech," he adds.
    So planetary destruction isn't guaranteed, though 10^29 Joules is an incomprehensible amount of energy. Saying it was 100 billion gigatons of TNT might as well be "a gazillion tons" ... though I wonder if that's a metric ton or an imperial ton.
  3. Re:Whats their contact information? on Google Sued for $1B Over Outlook Migration Tool · · Score: 1

    I fail to see why there would be *any* compulsion to sue. You're missing the three *necessary* elements to have a contractual relationship:
    1) an offer must be extended
    2) the offer must be accepted
    3) there must be an exchange of consideration

    Without these three elements, you've got squat. In your scenario, you've got an offer and acceptance - "I'll set up the Pizza Hut, and you'll do marketing and advertising." "Okay." - but if you don't contribute anything to the pot, the contract isn't in-place yet. (Note - "consideration" doesn't necessarily mean cash, but that's usually the easiest way to seal the deal.) In your scenario, if I open up an Italian restaurant across the street, do you expect to be able to sue me because it's a restaurant like yours? You might not like my behavior, but there's no law prohibiting it.

    In Google's case, providing access to the API toolset wasn't something specific to LimitNone, so they'll have difficulty proving that an offer was extended. Saying "we don't plan on making a competing offering" isn't a non-compete agreement. NDAs and NCAs exist for a reason, and they're executed in proper contract-fashion. LimitNone might have some traction with the UI design, but without a proper contract vehicle in place, it's an uphill battle. Having RTFA, I failed to see the words "breach of contract," and that's significant considering that the statement was issues by the lawyers. If there was a contract, I'd expect to see mention of it. The lawyers are claiming "misappropriation and fraud," which tends to indicate that a contract doesn't exist.

    I wouldn't expect Google to settle out of convenience, as that would set the "easy money" precedent for more nuisance lawsuits.

    I worked on a UAV program in the 1980s (back when they were called RPVs.) We went through several iterations of wing configurations. Joined wings, of almost any configuration, had absolutely bizarre aerodynamic interactions near the intersections. It's very complicated to get right, and usually doesn't provide an overall benefit - one particular aspect, like max cruise speed, may be improved, but at the expense of *everything* else.

    The wings on this aircraft don't seem designed for the mission profile described. Supporting forward infantry is a short-range low-speed mission profile. I expect the wings to have a low rake angle, and to be fairly chunky across the airfoil section. Low-speed wings are blunt and fat; high-speed wings are angled and skinny.

    At best, this is an "artist's misconception" drawing. Avionics, engine and fuel are going in the fuselage, as there's no room internal to those wings for anything but structure. Where did the payload go? Oh, "inside" ... with everything else. (The main site is slashdotted, so I'm working off an article from an Australian site.)

    In addition to begging the question, he has chosen a horrible "car analogy" basis. Horrible because it's ironic - the automotive manufacturers openly support the aftermarket modders. There's plenty of legal precedent stating that you actually own you vehicle - i.e. you're not under any obligation to use Mopar oil filters in your Chrysler product. But way beyond that, the auto manufacturers provide factory drawings to third parties for the express purpose of making replacement or accessory parts. They don't necessarily share the implementation details, but the specs are available.

    The automotive market isn't nearly as "closed" as Mr. Jaaksi thinks. If it were, the hood/bonnet on your car would be welded shut, and the only service opportunity would be at the dealership. Oh, and the manufacturer could download code to your vehicle any time they saw fit, altering the service interval information on a whim.

  17. Re:Which vehicles? on SwiftFuel Alternative To Alternative Fuels · · Score: 2, Informative

    I think you're missing the point. The volumetric energy density of batteries isn't up to the task. It doesn't matter if it's a pickup truck or a motorcycle - they all seem to go about 35 miles on a charge. Why? Because energy density is Wh/l or Wh/kg, and smaller vehicles carry fewer liters or kilograms of battery. Banging that lower energy storage against a lower energy requirement of the smaller vehicle - hey! about the same effective range. Imagine that.

    Have a look through the projects over at EV Album. Most of the folks are "hoping" to get 30-40 miles of range. All manner of budgets, motors and battery chemistries are represented. The results aren't stunning.

    Biodiesel and butanol represent renewable energy storage methods that are compatible with the current distribution infrastructure. Both may be synthesized from renewable feedstocks (that aren't food, dammit.) Moving toward all-electric is desirable, but it's not the immediate next-step. Battery storage densities need to increase by 10x (though 5x would probably be good enough.) The power distribution grid needs to be upgraded too.

    What? Why can't we just "plug in?" Let's compare the electrical power requirements of a current-day EV. Running a 6+6 flooded lead acid cell pack (six in front, six in back,) you've got 144V at about 50Ah. A full charge is 7.2kWh (we'll ignore the charging losses for now.) To charge in one hour, which the batteries will object to, requires 7.2kW. With a 120VAC source, which rectifies to a bit over 165VDC, you'll need about a 50A source. Don't have one of those at the office, do you? How about spreading that charge out over several hours? Okay, let's use an entire 15A branch circuit - you'll need 3.5-ish hours to charge the battery.

    I'll add some reference numbers. My electric power bill (looking at it now) has a one-year historical use chart on the back. My 4-person 3-bed residential usage is about 1000kWh for 30 days, or about 33kWh per day. My anemic EV needed 7.2kWh twice a day - outbound trip and return trip, recharging at the office. I'm going to need to increase my electrical usage by almost 50% to convert to EV transportation. The current electrical grid is barely adequate for the existing load. Oh, and don't forget that my wif has a vehicle too, so converting our family to EVs will double our existing electrical load.

  18. Transportation has issues on SwiftFuel Alternative To Alternative Fuels · · Score: 1

    The biggest issue with transportation is storage of energy. Gasoline and diesel have pretty decent energy densities - roughly 35MJ/kg. From both a mass and volume perspective, liquid fuels are compatible with the needs of vehicles. Batteries need at least a 10x increase in capacity to become viable for traction applications. The best LiFePO4 and NiZn batteries just don't store enough energy. The bleeding-edge EV guys are struggling to get 50 miles on a full charge. You can do about 10x that in your car, right?

    If you want a better interim solution, grow the biodiesel algae and refine the fuel into butanol. Butanol is compatible with gasoline distribution methods, though you'll suffer a slight reduction in range due to the lower energy density. Long term - adopt the Army's One Fuel Forward attitude, and make it a national priority. Get rid of gasoline as a motor fuel, and drive everyone toward diesel. Algae-based biodiesel is the only viable contender for fuel production, and it's not tethered to a feedstock that's also food. Using food as motor fuel is criminally stupid.

    We got a 2-bunk cabin, which is much nicer than trying to sleep in the standard coach seats. Overall costs were about $1600 (in 2003,) not including the additional drive from Sanford FL to Sarasota FL. The main benefit of the auto train is being able to do something else - get up, walk around, sit in the lounge car, have a meal, etc.

    However, the economics make this a very expensive trip. Travel time is comparable to driving. In today's costs: our Toyota minivan gets 24 MPG. Round trip is about 1200 miles, using 50 gallons of gasoline. At $4 per gallon, fuel costs are $200. The kids won't sit still for 16-hours of driving, so we split the drive into two days. Hotel costs us $150 or so. If we ate at restaurants for three meals each day, add another $200 in food. So driving costs me about $550, or about 1/3 that of taking the Auto Train. It's less expensive to purchase coach seating on the Auto Train, but that's not really an option if you have small kids.

    As a straw-man, I'll check prices for a flight+car from DC to Orlando. AirTran will get me four round-trip flights (2x adult, 2x kids) hopping through Atlanta for $900. Total flight time is about 4 hours. I can rent a mid-sized sedan from multiple vendors for under $300/week.

    Hopping over to Amtrak's website ... Standard coach fare is $450 plus $514 for the minivan. That's three coach seats - the infant is supposed to be lap-carried. Fat chance of that. Upgrading to the fourth seat for the small monkey brings the fare up to $540+$514 = $1054. Upgrading to the small family bedroom increases the round-trup fare to $2083 total.
