  1. Re:Nitrogen on Revolutionary Scuba Mask Creates Breathable Oxygen Underwater On Its Own · · Score: 2

    There's nitrogen dissolved in the water too.

    It's still bogus though. A device like that couldn't pull enough oxygen from the water to sustain a human. Not even close. A functional one would have to be far, far larger.

    Nitrox is oxygen-enriched for longer dive times - you can breathe less volume, and less nitrogen means you can go a little longer without decompression sickness. It's commonly used by recreational divers.

    You might be confusing it with heliox, which is a bloody-expensive helium-oxygen mix. No nitrogen means no nitrogen narcosis and greatly reduced decompression issues, and a below-atmospheric oxygen concentration solves the oxygen toxicity problem. It's rarely used by recreational divers because it's hard to swim after you've sold an arm and a leg to buy some. Heliox is the domain of deep commercial/industrial divers.

    The only way to detect them is continuous monitoring. It's just awkward and very expensive - a few advanced bug detectors on every floor are more expensive than having one man with one detector tour the building every evening.

    " mainly because a simple frequency scanner would allow one to detect the presence of transmissions by the device"

    Burst transmission. Buffer data for days, then send it all in a burst of under a minute. Nothing to detect unless the counterintelligence people are monitoring continually or get very lucky. It's old tech, dating back to the pre-IC days. Bugs back then did it by recording onto a magnetic tape. When the tape reached the end it turned on the transmitter and re-wound at high speed. The listeners then just had to play it back slowed-down and backwards to recover the original audio.

    Also, that cheap energy is a key driver of the rest of the economy. Cheap power and transport is what lets other industries thrive. It makes shipping goods halfway around the world and back economical, allowing for production to be consolidated in large factories to benefit from an economy of scale (and cheaper labor costs/regulations) and brings down the cost of goods. Cheap petrol allows convenient long-distance travel - the car created the suburbs, by allowing people to commute to work further from home. Businesses drawing in customers from a large area allows for the existence of the mega-store and shopping mall. Take away the cheap, subsidised energy and there will be knock-on effects in other industries.

    Got to be careful with the 'job killing' thing. Remember that businesses strive to minimise costs, and often an efficiency gain is what kills the jobs - a new technology allows one person to do a task that used to take ten, destroying nine jobs. It isn't as simple as it seems, because even if the jobs are lost the lower cost of production is then passed on to customers, lowering prices.

    The USA doesn't have a comprehensive policy because anything it does will be un-done as soon as power passes to the other party. Look at the recent repeal of the lighting energy efficiency standard, for example. With the two parties constantly bickering and trying to undermine each other, and the balance of power shifting every few years, commitment is a serious problem.

    If the US government coul commit to anything beyond the next term of office, they'd have their flag on Mars by now.

    HTML5's DRM component doesn't actually have any DRM in it. It's just an agreed interface by which propritary DRM schemes may be embedded.

    Given that the US has demonstrated their willingness to ground even diplomatic flights if they suspect Snowden to be on board, traveling would be risky. It'd need to be done with the backing of the Russian government, and I don't see why they would.

    The only options I see are to either hole up in an embassy or hope that Russian officials will be willing to give him residence as a PR thing. Russia and America have long been in a quite antagonistic relationship, even after the cold war ended, so it's possible some influential politicians might want to keep him as a show of independance - a small but very symbolic gesture to show that Russia bows before the demands of no country, not even the mighty US.

    6TB drives should hit the market properly in 2014. Let's assume it goes by up about 1TB a year - by 2020, that's 12TB drives.

    A case full of those could carry every remotely popular movie, TV series and piece of music from the last century. Even one drive could carry enough entertainment to last someone for many years. A lifetime of books.

    No, that's a franchise monopoly.

    A natural monopoly isn't granted, it's simply the situation that occurs when economic factors hand such an advantage to incumbents that no other may effectively compete.

    Franchise monopoly: City government goes to Big Cable Co and says 'you, and only you, are permitted to run cables in this city.'
    Natural monopoly: Big Cable Co invests in a load of cable-laying. As they are the only choice, they secure every subscriber. When others wish to enter the market, they realize that they'd also have to spend just as much in cable-laying, but that everyone who wants internet service is already a Big Cable Co customer, and switching is a lot of trouble - there's no way they could make back the cost of digging up the roads and laying cable as a newcomer to the market.

    Because we have no economic framework that could accommodate such a situation. It doesn't matter if machines can do all the work is there is no means to ensure access to their produce. Economics as we practice now is entirely centered around the labor market: People work for wages, use the wages to buy things, and producing those things pays wages back to the workers. Money circulates, everyone gets fed and clothed.

    Take away the jobs, and what are you left with? A few factory owners swimming in food and products they cannot sell because no-one has any money to buy it, and a load of ex-workers who have no money to buy even the essentials of life.
