  1. An oil shale field, not an oil field on Oil Deposit Could Increase US Reserves 10x · · Score: 2, Informative

    It has been known for decades that there is a tremendous amount of oil shale and tar sands in this area. The challenge, and it is a significant challenge, is to extract the oil from these deposits in a way that isn't an environmental catastrophe of epic proportions. As is often the case, the wikipedia article is a great introduction to the topic.

    Extracting oil from oil shale in the most obvious way involves heating it (probably with oil, but you do get more out than you put in, usually). So, you scoop it out of the massive open-pit mine, heat it, get the oil out, and then dispose of the remaining rock. Paradoxically, you end up changing the nature of the rock, so that it takes up more space than it originally did -- so even if you put all the tailings back into where it was mined, you'd end up with a new set of mountains. The net energy you end up with after processing the oil shale isn't a lot, and ridiculous amounts of water are necessary in the process (water the mountain west just doesn't have.)

    It should be noted that the Canadians are talking about building nuclear plants in their tar sands regions to supply the energy necessary to liberate the oil from the tar sands, in sort of a nuclear->oil scheme.

    According to the Wikipedia article, there have been oil shale processing programs in the past, some on a fairly large scale. They have fallen by the wayside as conventional oil has been so inexpensive.

    I believe that the environmental impact of extracting oil from oil shale on the scale required to keep the world running on oil as it is today would have a devastating environmental impact. Probably not as bad as a nuclear war fought over the remaining conventional oil resources...probably.

  3. Children of Men on Robots Entering Daily Life in Japan · · Score: 4, Interesting

    I thought the most thought provoking movie of last year was Children of Men, about the collapse of society when there are no more children. It was one of those movies where a simple premise is carried to the logical extreme, and it's more than a little depressing.

    But, coincidentally, the next day I saw a demonstration of ASIMO, Honda's self-contained little robot -- and it resonated so well with the movie that it's hard to believe in coincidence anymore.

    The Japanese are already living in that Children of Men world, their birthrate is shockingly low, and they have almost no immigration, so the population is shrinking quickly, especially of young people.

    So, what do the Japanese do? Rather than despair (as they did in England, in the movie) they just build a generation of robots...

    Simplistic, I know.

    I'm curious what the resolution of your display is -- you know, the one you're looking at right now. If it's more than 720x480, (and it is) then you can hardly say that resolution doesn't matter to people.

    We were watching my Academy screener of Charlie Wilson's War on my wife's new iMac (just because it was a new toy) and I was amazed how bad image looked. There were compression artifacts all over the place, and the resolution of the image was such that everything looked blurry all the time [well, when it wasn't blocky]. Now, I am sure that a screener doesn't have the level of compression sweetening/optimization that a commercial DVD release has, but if we had been watching this on bluRay, it would have looked far, far better even with hamfisted compression.

    Playing DVDs in their native format on a Mac shows a tiny little window in the middle of the screen. That's just not a realistic choice in 2008, certainly it won't be in 2010.

    I am a huge fan of the show "Sunrise Earth" on HDNet. Every frame of any one of their "episodes" looks better than any frame of any DVD.

    Music...maybe. Movies, no.

    To make a competitive movie today, it just costs a lot of money, mostly because the standards of the movie-going population are higher than they have been.

    Maybe not $100M, but at least $10M, which is not money that you are going to find under the seat cushions. Where is that money going to come from, if not from sales of movie tickets, DVDs, or paid-for downloads?

    My prediction is that if the trajectory of movie copying/stealing/downloading/piracy/whatever follows that of the music business over the next few years (and it probably will), you will find that movies will be funded primarily through product placement -- and that product sponsorship will inevitably affect the content of the movie.

  7. Probably both, it turns out on Will The Next Generation of Spacecraft Land In the Water? · · Score: 5, Interesting

    Lockheed, the Orion prime contractor, has expressed significant reservations about carrying the heavy airbags to the moon and back -- those 1500 lbs can better be used in other ways. On the other hand, there shouldn't be a problem with the weight on the more common missions to the space station and low-earth orbit, and the ability to reuse the capsule will be far greater if they put it down on land.

    The speculation in this week's Aviation Week was that they would have bolt-on airbags for the earth-orbit flights, and would recover those missions on the land, and would recover at sea for the moon-return missions.

    The reentry profile for the moon missions is really quite amazing. Recently Aviation Week had an article about it, describing how to get all the capsules to recover to the same spot on Earth. Do you recall way back in the Apollo days, they always described the narrow re-entry corridor? Too steep and you'd burn up, to shallow and you'd skip back into space forever? Well...

    For Orion, they plan to use a skip back into space to bleed off some of the speed coming back from the moon, and to align the craft to re-enter at the correct place to land where they want, off the coast of California. It's an incredibly audacious plan, with tolerances that have to be measured in tenths of a degree of entry angle. Very cool.

    It is well-known that the HD-DVD association gave some $150 million to the studios to release movies exclusively on HD-DVD as opposed to Blu-ray. Several studios have taken them up on this generous offer, as the linked article indicates.

    Now, I have no idea whether similar deals are in place for Blu-ray. Sony, of course, is a major studio on its own, so it clearly has a vested interest in releasing exclusively on Blu-ray.

    [disclaimer: I'm a bit of a Blu-ray fan, I like the higher capacities]

    It is likely that the days of physical objects for movies (whether they be DVD, HD-DVD, or dilithium crystals) are numbered. Even the writers noted this in their negotiations for a new contract with the studios -- at the last minute they gave up their demand for 8 cents on each DVD sale (as opposed to the 4 cents they are getting now,) almost certainly because they see that fighting over 4 cents on a DVD is fighting the last war -- not putting them in place for the next one.

  11. Tools needed to do this on FBI's Bot Roast II Sees Great Success · · Score: 4, Informative

    What kind of tools would the FBI, or any TLA, need to go after botnets?

    Assuming that the 'nets were employed to do something blatant (and this is surely not universally the case) you would watch the DDOS or spam attack and see what IP addresses were doing that, then you'd want to go back and see what machines communicated with those machines in the past, and the machines that communicated with those machines. Mining that information should, at some point, lead you to the systems that originated and controlled the attack.

    Of course, nobody has that information, right? Nobody can possibly save all the connections between all machines on the internet, certainly not for any length of time...[now is the time to get out your envelopes to do calculations -- I don't think it's by any means impossible to do this.]

    If you can't save the whole net, then perhaps you can set probes -- watch internet nexi for IP addresses to go by, once you've identified a few hundred thousand bot-infested machines. Assuming that a bot herder uses machines more than once [another perhaps unsupportable assumption] you could do the same analysis, more slowly, by tracking with these probed addresses as they come across the wire.

    I hate botnets, they will destroy the 'net, but I'm not sure that the solution is any better than the problem.

They are so-called maxi-scooters, and are very substantial machines, about the size of a Harley and not a Vespa.

  18. A half-measure at best on Predator-Style Helmets Allow Pilots to See Through Planes · · Score: 4, Interesting

    Or maybe a quarter-measure.

    Fighter planes design is very compromised by the requirement that the pilot be able to see out the canopy. Typically, you find the cockpit cantaleivered way out in front of the center of gravity. In more recent planes, the requirements of stealth require dramatic measures to enable vision from the cockpit while still maintaining a low radar profile. I feel, too, that in any serious war you're going to find that the easiest way to bring down an airplane is to blind the pilot with lasers.

    So, put the pilot right in the middle of the airplane in an opaque cockpit. Put a large number of wide-bandwidth sensors on the plane that would enable the pilot to see better than he could with his own eyes, certainly over a wider frequency and contrast range. You could armor this cockpit much more easily, it could be far more stealthy, and it could be far more structurally sound. You could have redundant sensors that could be deployed if the primary sensors are blinded.

    Now, some might say that we should go all the way and put the pilots on the ground -- and they have a point. But, I think that the amount of bandwidth available inside the plane would be far greater than you could ever hope to transmit securely over the air.
