  1. Re:waste of time on New Chemical Process Could Make Ammonia a Practical Car Fuel · · Score: 1

    Roundabouts do scale well with traffic, that is in Europe. America is a different story because better than half the drivers treat the roundabout entrance as a stop. I've seen dozens of roundabouts that pass less traffic than a 4 way stop, in the US. A good portion of this is because most of the smaller ones are designed by land developers who think roundabout means circle when in a properly designed roundabout traffic rarely moves purely circular.

    From what I seen the only thing they claim is splash proof ratings like IP66 (even if their marketing shows dunking in water) which only account for incidental water and can't be in direct rain for extended periods of time. There is a significant difference between splash proof and rated to 100m underwater. Heck there is a significant difference between splash proof and 1 foot underwater. Any depth of water over a few inches requires heavily secured and reinforced rubber seals (typically under pounds of pressure) to ensure water can't penetrate. And frankly I don't see any way you could do that unless you had a watertight pigtail hanging off.

    As I said this and battery life are the most significant issues for me because they are tied together. When you replace the battery on a watch with a waterproof to depth watch you MUST replace all the seals or you can't guarantee water resistance. Even though the coin battery powering a standard phone can be had for about $10, you've got to remove the seals, clean the seats and put new seals in. If you have a jeweler (where 90% of watches are sold and often the only qualified people to do the work) do this you can often end up paying anywhere from $50 to $100 to have this done right. On an inexpensive watch this could be more than a new watch costs, and even on a moderately priced consumer watch (such as mine) it's 1/4 of the value. Only with high end multi-thousand dollar watches is this even a small percentage of the price. And though you can probably buy the seals these days on the internet back even 10 years ago the only place you could even get them was from an authorized dealer for the brand which was pretty much a Jeweler and 90% of them would refuse to sell just the seals to you.

    If I have to attach a cable it's not waterproof. If it uses enough energy that it must be charged everyday (my current watch can go 6 months or so without exposure to a single source of light) the battery is unlikely to last much more than a couple years meaning the whole battery replacement thing is back. I want watch that will not require a single battery swap in it's lifetime (this is the single most expensive part of watch ownership and replacing the battery always destroys the water resistance unless all the seals are replaced with the battery), will last at least a decade, is waterproof (my preference is for at least 100m but I could tolerate as little as 20m), it must keep time, have a perpetual calendar and look like jewelry, have an adjustable, removable and replaceable band that's interchangeable with standard bands used in the watch industry, it needs at least one local time setting so I don't have to reset the clock when traveling and a stopwatch function would be nice though not required and I'd prefer a sapphire crystal for the face.

    I've got all of that in my current watch except for the sapphire so the face has a few scratches on it. But Citizen was smart enough to put a raised metal edge around the face so it's less prone to being scratched.

  7. Re:It's always dark matter. Except when it isn't. on Mysterious X-ray Signal Hints At Dark Matter · · Score: 1

    I think of this like string theory. They've got an answer searching for a problem.

    Dark matter is one of those as well. They've theorized dark matter and attributed each unexplained item in astrophysics to it but have no real evidence it exists. As the other reply said to you this is not any different than the luminiferous aether that preceded it. Dark mater may or may not exist, but it would be foolish to attribute that which we can't explain to something that we can't see or measure. All those attributes of dark matter could easily be explained by other possible items including cosmic strings, wormholes, etc.

    Dark matter is currently in vogue, that doesn't mean it's reality. Much of the hype behind dark matter is that if it exists and there is enough of it then it would explain the big bang. This has created a desire among some in the scientific community to want it to be true because it presents a nice clean solution with a recyclable universe. My personal feeling on it is that we're missing something big, that something is the explanation for where all the anti-matter went and it might explain many of these other anomalies that some are attributing to dark matter. I'm probably wrong, but I'm willing to bet so are the dark matter proponents.

    I currently wear a Citizen Eco-Drive watch. I think I bought it 10 years ago. The watch face is a solar panel that charges itself when it's exposed to light. The watch also has a perpetual calendar (don't have to set the date), it has stop watch and chronograph functionality and it looks like jewelry.

    But the two single most important features for me were the never having to change the battery and the perpetual calendar (never having to set the date, even on leap years). I just shake my head at this "smart" watches, I'd go insane if I had to charge the watch every day and a bit of rain could ruin it.

The offered a couple million dollars cheap tents that were probably worth less than a million dollars.

    You know what the US did? We deployed a carrier group and starting rescuing people directly, feeding them, setting up housing and providing medical care onboard the navy ships including emergency surgery for those critically injured. That relatively cheap soft power exercise for the US bought long term good will in the Philippines, in fact they actually started talking about maybe letting us open a base there again (it's bared by their constitution). We didn't really spend that much more than the Chinese claim to have spent but we got 200000x the value from it.

    At the time these were developed NATO did not believe they could beat the Soviet forces without them. The soviets had something like a 3:1 armor advantage to the NATO forces and when combined with Warsaw pact forces they outnumbered NATO forces as well. The late 40's and 50's were pretty scary in this regard because western Europe was devastated and trying not to starve to death and the US had mostly demobilized while the Soviets still had their entire army and had increased heavy weaponry in the interim. If the Russians hadn't poisoned Stalin we probably would have had WWIII as he'd already put in motion the plan to create an incident that would lead to war.

    When the ICBM and Submarine based nukes came online in the mid to late 60's it ended the need for the tactical nukes as you could assure MAD at that point. In the late 40's and early 50's the lack of these weapons prevented an effective strategic nuclear MAD strategy as the only way to hit internal strategic targets was with long range bombers which were susceptible to being shot down with conventional weaponry. It's arguable that until long range weapons against which there was little defense were developed MAD didn't really exist and that tactical weapons were the only thing that prevented war.

  16. Re:Nuclear Artillery on The Revolutionary American Weapons of War That Never Happened · · Score: 2

    There was a MASSIVE soviet tank army standing by in Eastern Europe after the end of the war. The Soviets never stopped building armor after the end of the war and kept piling tanks in the East. The official NATO defense strategy was to drop nukes on the line of that army as soon as it crossed the border. This required quick deploy nukes. The M388 was actually one of the larger rounds, there was a very tiny jeep launched one as well that would only go about 5 miles (think about that job for a minute).

    The point was NATO and the US developed these weapons, deployed them and let the Soviets know we had them. It likely helped prevented WWIII. The third world at this point was still trying to acquire weapons like machine guns. You shouldn't look at history through the warped lens of todays concerns. The Soviets were the concern, not some third world country without semi-automatic rifles.

    It said in the article that the plastic itself, once converted to fuel is used to fuel the process which is converting the plastic to fuel. In other words they pull off a little of the fuel converted from the plastic to fuel the process going forward. Other than the initial startup energy it should be energy independent.

    Plastic is a nasty waste product (it doesn't biodegrade and it kills living things) that we need to find a way to either reuse or properly destroy. Converting the several trillion tons of plastic waste in US landfills into fuel oil not only saves the space in the landfills it recovers energy from a waste product. It's a good idea if the total economics of the setup are profitable enough to justify hauling it to a disposal site or small enough to build these at landfills. It's a damn good waste reduction technique that will ensure we don't end up with the planet in the movie Wall-E (which was buried in garbage like plastic waste).
