    Even if private individuals could use the NICS system there's no point in making a law requiring it. The honest people will use it whether it is required or not since it protects them from liability, while the criminals will just ignore the law regardless.

    We should have laws for things that are inherently wrong, like murder. Owning a gun is not inherently wrong, and therefore should not be prohibited since the attempt to do to won't prevent criminals from getting guns illegally anyway.

    $100 million is nothing compared to the scope of the problem. The Manhattan project was around $25 billion over about 4 years. The Apollo program cost $170 billion over about 15 years. The reason why fusion hasn't worked yet is simply because it hasn't been funded to those levels yet.

    The notions that solar power doesn't work and that solar power hurts utility company's profits are not mutually exclusive. It is called negative power prices. Due to laws requiring utilities to buy wind and solar power at any time, combined with the inability to store or transport natural gas supplies due to lack of pipelines, the cost of electricity often becomes negative where the power company pays customers to waste electricity because of unpredictable excess capacity. This hurts utility company earnings as well as being wasteful and counterproductive to the economy and environment.

    Oh yeah? Just ask this guy. He was absolutely arrested for not consenting to a search by lying cops. And as shown in the video, the prosecutor states that if he wasn't lucky to have had a clear recording they would have no qualms about and would have gotten away with lying to convict him. The linked video is full of all sorts of blatant gestapo corruption on the part of the cops AND the court (at one point the judge called the sheriff to arrest him for not letting the prosecutor see exculpatory evidence, when sheriff arrived he simply told the judge he couldn't arrest him for that).

    Thorium is not fuel, it is only fertile material which can be turned into Uranium in a breeder reactor (which requires high-enriched uranium or plutonium to operate). Thorium has the same properties as Uranium in terms of risk of melting down. Making a reactor melt-down-proof is a matter of reactor and coolant type, not fuel. Same goes for nature of spent fuel/radioactive waste. The only real advantage of using thorium as a breeder material instead of natural uranium is that it is more common and cheaper.

    There's a simpler way of looking at the electric car conundrum. Of all the energy used in the industrialized world, about half is used for transportation in the form of oil.

    Actually that is not true either. The plants were in fact originally designed to load follow and were only later adapted to constant full power operation based on economic factors. It is not hard at all to engineer the plants to load follow. And xenon poisoning has nothing to do with it, the primary challenge is in axial offset control which becomes more difficult later in the cycle, but only because the cycles are optimized to run at constant full power with maximum fuel loading. It would only require modest adjustments typical of cycle-to-cycle operational changes to design to load follow. IAANE.

    Everyone one of your points is entirely false.

    1) No. Wind and solar vary with clouds and wind patterns and have no correlation to usage patterns. Renewables do not cut into anyone's profits, only natural gas does that with massive oversupply with lack of storage/transmission capability. In fact, renewables tend to be big profit cash cows for industries because of government subsidies that pay for them to build them, even when and where they don't work, and then they get to write off the losses from taxes. Why do you think there are so many idle wind power farms all over the country?

    2) Renewables are also highly centralized in that they are totally dependent on federal government subsidies and all the cronyism and corruption that comes along with it. The rest of point two I won't even go into as it is just loony bullshit.

    3) What do you think causes the cost overruns? Environmentalist protests and lawsuits. Nice catch 22 there.

  11. Re:No, because they are not compatible on Should Nuclear and Renewable Energy Supporters Stop Fighting? · · Score: 1

    Wind and solar have variable output, so they need to be partnered with flexible power generation. Nuclear is fundamentally inflexible because you can't quickly ramp up or down electricity output from a nuclear power plant.

    See this short video for a nice explanation of the incompatibility:
    http://www.ilsr.org/coal-nucle...

    Wrong. Nuclear power can load follow (ramp up and down rapidly to meet instantaneous demand) perfectly fine. They just typically do not because they are large baseload plants and there is no reason to run them anything lower than 100% when you need fossil fuel plants to make up the difference. IAANE.

    The most egregious example of administrator disconnect, as uncovered by Feynman, was the notion that the O-rings had a safety factor of 3 because they were on burned through 1/3 of the way on previous launches:

    Instead of being very concerned that variations of poorly understood conditions might reasonably create a deeper erosion this time, it was asserted, there was "a safety factor of three." This is a strange use of the engineer's term ,"safety factor." If a bridge is built to withstand a certain load without the beams permanently deforming, cracking, or breaking, it may be designed for the materials used to actually stand up under three times the load. This "safety factor" is to allow for uncertain excesses of load, or unknown extra loads, or weaknesses in the material that might have unexpected flaws, etc. If now the expected load comes on to the new bridge and a crack appears in a beam, this is a failure of the design. There was no safety factor at all; even though the bridge did not actually collapse because the crack went only one-third of the way through the beam. The O-rings of the Solid Rocket Boosters were not designed to erode. Erosion was a clue that something was wrong. Erosion was not something from which safety can be inferred.

The only reason for this program was to provide a failing country with a cheap way of disposing of highly hazardous materials without losing face. It is the proverbial "turning a negative into a positive". It will have zero effect on our energy costs or programs.

    Sorry for being so harsh, but your last statement there pegged my bullshit meter.

    The small increase in nuclear fuel price due to the ending of this program is insignificant. Fuel price is only a small cost of nuclear power, and enrichment cost only a fraction of that. The real problem for nuclear power is the bottoming out of energy prices due to the huge oversupply of natural gas from fracking.

    Gun ban and gun regulation isn't the same thing.

    In northern Europe guns are heavily regulated and they don't have nearly as much violent gun crime as the U.S.

    This might not necessarily be because of gun regulation, not having gun nuts around is probably the big thing but I don't think killing them off is an acceptable solution.

    The vast majority of gun crime in the US is related to drugs or gang related. 50% of the gun crime in the US is perpetrated by 4% of the population in the 7 largest major cities (several of which have total gun bans already - New York, Chicago, etc). The gun crime in these areas is similar to that of other countries which have total gun bans, such as Mexico, Russia, Brazil, etc. These countries (and parts of the US) have high gun crime not because of lax gun laws, but because of a degradation of the rule of law and civil society. Most parts of the US, especially rural areas, have far less crime than anywhere in Europe.

Like two people bungee jumping, while decelerating under tension, they notice the cord start to break due to excessive weight, so one guy detaches himself and falls to his death while the remaining elasticity of the cord is enough to save the other.
