  1. Re:Not surprising at all on Energy Production Is As 'Dirty' As Ever · · Score: 1

    According to wikipedia, cancer and radiation poisoning deaths from Chernoble is under 200. Skimming the article, it looks like long-term premature deaths should not exceed 2000, although many cases of operable thyroid cancer will have to be dealt with.

  2. Re:That's what happens... on Energy Production Is As 'Dirty' As Ever · · Score: 2

    Hydroelectric generators have to be shut down for maintenance roughly every 2 years. That wind generators have to be replaced every 12 years is not bad. Perhaps replacement is not strictly necessary and they could be repaired/rebuilt at that time? Towers and bearings and generators can be made to last hundreds of years, so apparently what is going wrong is that the blades are eroding. If that's the case, replace/rebuild/refurbish/refinish the blades once a decade - or use more durable materials.

    An additional factor is Obama's war against the coal industry. Although his policies hurt both production and use, the heaviest burden falls on users. U.S. users find other energy sources, coal prices drop and become attractive to buyers in other countries.

    It's so sad. "Environmentalists" like you have become so obviously unable to predict the effects of what they're arguing against that their navel-gazing produces contradictory results, and they can't even see the contradiction.

    If you don't use words in a commonly accepted manner, your attempts to communicate with other people will fail. So saying "Dirty means whatever I need it to mean" gets you derision, and earns you a childish reputation.

  8. Re:Dumb title: CO2 is not "dirty" on Energy Production Is As 'Dirty' As Ever · · Score: 1

    At high enough concentrations, CO2 can be tasted. It forms carbonic acid in water (saliva), and it tastes ... well ... acidic. Before that concentration is reached CO2 can be sensed by the stinging sensation on eyes of the carbonic acid forming in tears.

    According to my quick calculation, 2GW is equivalent to boiling off 13 cubic feet per second of water. That's in the range of a large groundwater supply, but would be a poor use of groundwater. 13 c.f.s. is a very modest river. Compare this to the Niagara River at 100,000 c.f.s..

  11. Re:Much better than I expected on Speeding Object Makes Small Hole In the ISS Solar Array · · Score: 1

    To some extent it depends on the size and speed of the impacting object, however in most cases this is going to be like a high speed bullet (very high speed, 8X normal) hitting a sheet of metal. It either dents it like a bullet hitting a highway sign or punches through. For things to be blown apart, the initial impact would have to be large enough and fast enough and have the right substances involved to cause a lot of shrapnel, which blows out the far side.

  15. Iron on Sandia Labs Researcher Develops Fertilizer Without the Explosive Potential · · Score: 2, Insightful

    Although iron is typically deficient in soils and adding iron promotes growth, is the amount required to make a high nitrate fertilizer difficult to explode going to poison the soil over a period of several years? Will it make the iron content of foods too high? I don't know. Is there some agricultural expert here that can illuminate the subject?

    Yours is one of the better criticisms of Common Core that I've read. I'll just add that in addition to the English curriculum being weak and misguided, the math curriculum is the same. Instead of aiming for calculus, C.C. drifts into statistics. While there is some value in statistics, it seems like something a bureaucrat values. Calculus is important to technology, which makes it important to our future.

  21. Re:By Science Fiction, does he mean.... on Politician Wants Sci-fi To Be Mandatory In School · · Score: 1

    Novels generally have a view of the universe, that it is a good place, or neutral, or malicious. Dune is in the third category. It's difficult enough to get through school without reading a novel like Dune that attempts to make you believe that it isn't worth trying.

  23. Re:Flying Cars on Why We'll Never Meet Aliens · · Score: 1

    If you bother to study enough airplane and automobile technology, you will learn that a flying car for general purpose use is not practical. Consider that you'd want something smaller than about 20 feet by 10 feet. Make some simplifying assumptions: it never needs to travel on roads, cutting out the weight of wheels. Vertical takeoff and landing is required, all travel is between home and parking lots. Controls must be automatic and thrust in all directions must be adequate to take off and land in 60 mph gusting winds. Load capacity should exceed 400 pounds. Operating costs should not be excessive, and the vehicle must be very reliable. Initial cost shouldn't be excessive.

    How would you accomplish that? You're pretty much limited to a helicopter design, and they're expensive and require an awful amount of maintenance

    On the other hand, if you want a car that you can drive to an airfield and take off there, fly, then land and drive to your destination, you need some sort of folding or collapsible wing. It would be difficult to make the car sturdy and roadworthy. In the end, the resultant car is peculiar and inferior, and the resultant airplane inferior also.

    Some day, better engines, better materials, and better automatic controls may make one or both of these technologies not excessively expensive, but given the state of the art, it's not reasonable to expect it to have happened yet.
