  1. Who paid for the procedure? on Who Owns Pre-Embryos? · · Score: 1

    Seems simple enough.

    If they split the cost, then half the embryos belong to her, half belong to him.

    If the laws say that the genetic daddy has to pay child support, he is just going to have to deal with it.

  2. Re:The grid needs storage - not battery storage on Why Our Antiquated Power Grid Needs Battery Storage · · Score: 1

    There are a lot of household tasks that use electricity that can be rescheduled to reduce peak demand. Water heating is a prime example.Lots of folks take a shower in the morning and leave the house. The water heater turns on to make water that will not be used in great quantity for 8 or even 24 hours later. If the water heater were smarter, it could keep a little hot water available for washing hands and stuff, but recharge overnight.

    Your freezer could work in a similar way. It could be set to get colder at night and a little warmer in the day to reduce peak demand.

    Air conditioning systems could run dehumidification cycles at night to help reduce the burden during the day. They could also increase temperature slightly at the neck in the 'duck curve' (late in the day where solar generation is ramping down, but demand is still very high).

    Clothes drying and dishwashing could be scheduled to run at night.

    The simplest way to make all this happen is for the utility companies to start charging different rates depending on the incremental cost of the power being generated. The utility company would update your meter several times a day, the meter would communicate with your appliances and you would have to decide if it is all worth it.

    Battery storage at the household level may be part of the solution, but it is difficult to justify for most markets at the current prices of electricity and batteries. If you were paying a dollar per kilowatt hour for peak rates, you might think a little differently.

  3. Re:So Germany is not a state? on California Has Become the First State To Get Over 5% of Its Power From Solar · · Score: 2

    Getting a core non-critical is the _easy_ part. Change of core geometry, loss of moderator, pretty much anything will take the core non-critical. The cooling down part is what is tricky. You don't just have a big chuck of material at some temperature that simply need cooling, the core will continue to generate gigawatts of heat due to the decay of short-lived isotopes for several days/weeks after it has been rendered non-critical. Simply dumping nuclear lava on a concrete floor will not work. You have to spray it or flood it with borated water which will produced copious quantities of highly contaminated hot water, steam, and hydrogen. You can't keep all that material in your containment building...

    The disaster at Fukushima Daiichi clearly demonstrated that containment buildings are all but worthless.

  7. Last fully supported version of Windows on Microsoft Ends Mainstream Support For Windows 7 · · Score: 2

    I have noticed a trend. There are several engineering software packages that I use that simply will not run under Windows 8. The vendors have basically said use Windows 7 (or even XP) or move to Linux. This obviously does not affect most users, but it is interesting.

    I have used the UI for Windows 8 for a couple of years now. It works, but I do not like it. I think it is rather poorly designed.

    So other than the fact that it will not run the programs I need and I do not like the UI, I guess it is a pretty good operating system.

    Have you complained to Keurig directly about the "genuine K-Cups" that will not function and asked for replacements? The only way to prevent this sort of crap is to raise a stink about it. Also consider returning the coffee maker and gving it a negative review on Amazon. Seriously, why are you putting up with this quietly?

  15. Re:No, It Won't on New Study Projects World Population of 11B by 2100 · · Score: 1

    Note that the income of the 1%, if distributed evenly among the 99% would represent only about a 14% pay raise across the board. The wealth of the 1% would nearly double the wealth of the average American, if uniformly distributed.

    Claiming that redistribution would double the average wealth is not quite right. The upper 1% control about 30% of the wealth. Redistributing this would make everyone else 30% richer on the average. Doesn't sound like much, does it?

    Let's put numbers on that. There is about $120T in total wealth in the US. The upper 1% control about 30% of this, or about $36T. The population of the US is about 310M. That comes out to a redistributed wealth of about $120,000 per person, or about $360,000 for a family of three. So basically you are talking about a house, free and clear in a moderately high end market for every family in the US.

    Exit row seating usually offers a bit more leg room with no reclining seats in front of you. It used to be free, now many airlines charge for it. Therer is no shortage of takers.

    I am 6 foot 6. I would rather stand for two hours than try to sit in one of those seats. Only problem is that i am not allowed to stand (I have asked) and on many planes I can't stand up straight anyway. I don't need the knee defender. If you are sitting in front of me, you will not be able to recline your seat.

  17. Re:people charge of traffic lights are engineers b on It's Easy To Hack Traffic Lights · · Score: 1

    You would be surprised how conditioned you can become to traffic patterns always being a certain way. I nearly caused an accident last week when I turned left in front of a car that was going straight. I am a good driver... why did I do that? The intersection was where two small neighborhood roads intersect the main road. After I screwed up, I realized that In the last 25 years, I had _never_ seen a car go straight through that particular intersection. I unconsciously assumed that he was waiting for the light so that he could turn left, like cars always do.

    Traffic engineering is not about saving gas. It is mostly about preventing accidents. That is one of the reasons you see so few Yield signs these days.

    Do you have a cite for this decomposition into carbon tet? You would have to knock the fluorine(s) off the R11 or R12, that is not so easy to do.
