  1. Re:Isn't that fision? on Two-Laser Boron Fusion Lights the Way To Radiation-Free Energy · · Score: 3, Informative

    No. Boron first absorbs a proton (fusion) and becomes an unstable isotope of carbon, which then splits (fission) and gives off X-rays, gamma radiation, and alpha particles, and a few neutrons.

    Most of our power generation in the US comes from coal . . .

    Coal accounts for significantly less than half of current US electricity production - natural gas is a close second & closing.

    Most of our natural gas comes from Canada. . .

    Most of our natural gas comes from fracking in places like Texas, North Dakota, Pennsylvania.

    The only thing we import in scads in oil, and I guarantee, those who control the oil aren't getting stolen from.

    "Those who control the oil" being the operative words here. Historically, western powers have tried to control those in power in oil rich states. (right now, that's not working out so great in Iraq, Iran, Venezuela, etc.)

  3. Re:Switch-mode power supplies on NSA's New Utah Data Center Suffering Meltdowns · · Score: 1

    I know from personal experience that this area has (at least had in the 90s) poor reliability from the electrical utility companies. When they found out the building we were designing was going to have 3.2 megawatts of back-up power, they offered to give the Owner a reduced electrical rate if they agreed to an interruptible feed from the utility. The Owner thought about it, but found that it the deal would not only require increasing the capacity of the back-up generators, but also require red tape to deal with the EPA, so they decided against it.

    I believe you are talking about the price of electricity to the customer, while GP was talking about the cost to produce at the plant, not including distribution, profit, etc.

  6. Re:Water intensified the effect? Duh on Tesla Model S Catches Fire: Is This Tesla's 'Toyota' Moment? · · Score: 2

    Firefighters often use water in fire where they cannot directly put out the fire by dousing the burning material with water. This is because the water cools things down. This helps prevent adjacent materials from igniting, and can help to extinguish the fire by pulling heat out of it.

    Considering it costs millions of dollars for the installation of an MRI in a hospital, and it produces tens of thousands of dollars a day in revenue for the hospital, and that before this agreement the price of liquid helium has jumped to $25-30 per litre from $8 last year., I doubt that it would significantly affect the cost or availability of MRIs.

    My mom, around 80 years old at the time, broke her arm on a Saturday, went to the hosptial. They gave her some pain medicine, a sling, and told her to go to her primary car physician on Monday to get it set and cast.

    Incorrect. What they want is to increase profits to the maximum amounts, and pesticides and antibiotics ain't cheap.

    True, but antibiotics have the effect of making the animals gain more weight. The farmer can make more than the cost of the antibiotics back by selling more product, and so has an incentive to use them whether or not the animal is sick.

    65 million years ago we had a few things: Large macroscale life like Dinosaurs and giant mosquitos, a large supercontinent named pangea, no ice caps, and CO2 levels ten times as high as they are right now.

    65million years ago we had oxygen levels around 35%.
    250 million years ago, we had ocean acidification that helped wipe out 95% of the complex life forms in the ocean.-
    None of that implies that the current trends are good for us.

    . . . before a buyer and a seller can meet to make a trade they both need to signal that they have the intention to do so.

    . . . There's no magic signal of intent to trade before an order is placed.

    I believe you are wrong. For a seller to sell, they first have to offer stock for sale at a price; for a buyer to buy, they first have to offer to buy stock at a price (or at least one of those has to happen). If they don't agree on the price, there is no sale, but there is a signal of intent that "everyone" can see ("everyone" being those that are fast enough).

  22. Re:Power requirements? on New Ship Will Remain Stable By Creating Its Own Inner Waves · · Score: 2

    You can't reasonably expect the ocean to rock the boat at the resonant frequency of the internal water tanks. Therefore the ship's internal wave system is going be expending a considerable amount of energy.

    You can if you tune the resonant frequency of the tanks to the general frequency of the waves and use the air valves TFA talks about to fine tune the resonance. I know, for example that tuned water tanks are sometimes used to dampen swaying of high-rise buildings.

    I take that to mean that 64% of the studies were not about AWG, therefore they don't have anything to do with a statistic about the papers' endorsement or rejection of AWG.

    Why is this surprising?

    It makes sense that if all of the stars that formed the nebulae came from the same giant swirling cloud of gas, then the stars formed would tend to have angular momenta mostly aligned upon that same axis.

    It's surprising because the bipolar axis observed is at right angles to the axis of angular momentum. It even says as much in TFS:

    'Many of these ghostly butterflies appear to have their long axes aligned along the plane of our galaxy.'
