Re:Who fail to learn, re-implement Unix badly.
The science of computing existed well before the first computers.
You've got it backwards, there was no "science of computing" unless you count mathematics as a science (some do). The first "computer science" programs were established after, and in response to, the invention of electronic computers. As much as people like to rave about astronomy and telescopes, CS is very much about studying the mathematical properties of computing machinery.
Computer Science as a degree didn't exist until around the 80s.
This is the part that is unequivocally false.
Take U of Pittsburgh, for example:
MS program in 1966/67
PhD program in 1970
BS program in 1974 -

Re: Hydroelectric power and Nuclear Energy??
Well, it's not from the levelized cost of energy, as nuclear is better than most renewables, and the always-available nature is highly attractive. But it is extremely expensive, especially because of activist intervention delaying development for 5 to 10 years, or more...

Re: An extreme metaphysical position
Yo!
... iggymanz! Physics degree, eh? You might enjoy this:http://philsci-archive.pitt.ed...
Click on the PDF download on that page. Turns out physics is moving right along with GR-QFT reconciliation, although I have no idea how many are paying attention. Dr. Mark Stuckey, et al, have a book due out soon, "Beyond the Dynamical Universe", that I've been reading the Kindle version of
... the physics is great, but McDevitt's "neutral monism" philosophy is ridiculous (not a Philosophy precedent, by any means). Just Google-Scholar "Stuckey Silberstein" for heaps and gobs of papers.Of course, neither STR nor QFT explain a perceived "now"
... what's needed for an explanation requires a cross-discipline investigation ... physics + neuroscience. All 100% science, no emotive urges anywhere.Your "known phenomenon" is essentially Presentism, which is most compelling until you realize that the Block Universe of STR via RoS (Stuckey's Blockworld) has no flowing present time, no "now" and certainly no dynamical behavior at all. It seems a minor logical exercise to note that, if something doesn't exist in the universe, it must be an artifact of consciousness, so both the illusion of a flowing present time and the feeling of "now" are rooted in the stream of consciousness. Note that the illusion and the reality feel exactly the same.
"Einstein's Breadcrumbs" (EB) specifically addresses this alternative:
"Indeed, the reality of our experience of the flow of consciousness and the perception of change within that flow perfectly explain the illusory feeling of the flow of time as well as explaining its stubborn persistence. Coupled with the illusion of “now” it's obvious why the illusory feeling of the flow of time gives rise to a belief in Presentism – Presentism is the way it feels. Note, however, that an actual, biological feeling of flowing time is impossible because we cannot feel it – we have no sensory inputs attuned to flowing time, a most reasonable arrangement considering that it doesn't exist."
The "now", of course, is simply a feeling of the immediacy of conscious experience. I don't currently have EB posted somewhere that I can provide you a link to
... the "ERLTalk @ outlook.com" email allows me to send you a PDF copy. I believe you'd benefit from reading it, so please reconsider your email reluctance -- lots of substantiating quotations from physicists and sources identified, as well as a wealth of explanation that's simply impossible to post. EB is 25 pages long, including footnotes. I'd much enjoy and surely benefit from your thoughts about it.Consciousness in the Block Universe also looks very much like a most impressive simulation architecture and I've discussed that idea in a separate section. I hope to see your email
... I won't do anything but email you the EB PDF. Should you decide to exchange views after reading EB, simply let me know and we could continue emailing. -
Re:If you really cared about climate change
On the other hand, the cost of nuclear power in the USA is pretty much 95% the fault of Democrats. Various Democrat sub-groups came up with a plan to use the courts to make nuclear power too expensive, and it worked. This has been very well known for about 3 decades now, despite nonstop gaslighting to push the myth that the cost of nuclear power is either a mystery or the natural consequence of physics or engineering.

Re:One guy
If women are different from men in a way that would result in them having diverse perspectives, then why is it unreasonable to assume that those same diverse perspectives might lead them to other career choices?
As to your second point, the evidence seems to point the other way. I believe it was you who made a post in the previous thread in this topic indicating that Iranian women were more likely to be involved in software jobs as some evidence that it must be socially based. Interestingly enough, you'll see higher rates in other countries too. India is one example where there are significantly more women in computing. What you fail to understand is that this has little to do with cultural differences (and you'd be hard pressed to argue that either India or Iran have better views towards women in general than western democracies) and is the result of economic ones. Computer science jobs are well paying and in high demand, and do potentially afford you the opportunity to immigrate to a western democracy that may be preferable to the type of people who are intelligent enough to excel in the software development field.
When you remove economic pressures (the Scandinavian countries which have among the best social safety nets have the same low numbers of women in CS as the U.S.) and have a society that leaves you essentially free to pursue whatever ambitions you might have, it is hardly unsurprising that any biological tendencies that may predispose people to one field or another are more prevalent. To use an analogy, you can only really see if one strain of plant yields more only after you ensure that they all have sufficient water to thrive. If you somehow created a society that was able to ensure that everyone in life had an equal start, the only possible variance left would come down to biological differences.
There's a substantial amount of evidence to suggest men and women are different. Even at a surface level, we see large differences in things like personality, which has been demonstrated to be highly heritable. I'm not quite sure how you could look at those differences and come to the conclusion that it isn't going to result in differences in vocation selection or other life choices that can impact a person's career. I suppose you could argue that somehow all of these differences are merely a result of society, but that ignores the heritability of personality as well as evidence from studies that examined sex-based behavior difference in infants. See a recent study that examined children roughly one to two and half years of age in nurseries, a similar earlier study which examined infants 1 - 2 years of age , and another study which examined infants as young as three months old. There was another study that examined toy preference in young monkeys that found similar sex-based differences which does suggest that this is something that goes back quite far in our evolutionary history.
It's funny that you bring up global warming, because a lot of the evidence suggests that you are incorrect, yet you continue to act in much the same way as people who contest the science behind global warming. I seriously question how you could reconcile the studies I've presented above with your beliefs that biology plays such a little role in the outcomes we're observing. I suppose you could claim the science is biased, but then how do you know that the scientists publishing articles about climate change aren't biased? -
Hmm, where have I heard that before?
Originally scheduled to come online by 2018, the V.C. Summer nuclear project in South Carolina had been plagued by disputes with regulators and numerous construction problems.
This is by design. The left has seized this approach above all others to kill nuclear power plants.
They have networks of friendly lawyers who file bogus suits before amenable judges. They have friendly regulators that change the rules midstream. The effect is delay, delay, delay. And that means cost, cost, cost. While tthe construction site sits idle, the utility often has to pay a squadron of union electricians and/or plumbers to sit around while it is resolved in court or while engineering updates the plans to take into account the newest retarded rule change.
A few years delay can double the cost.

Re:Smart move. Nuclear Fission isn't cost-effectiv
That's the plain and simple truth. Nuclear Fission only looks like it works if it is cross-funded by obscene truckloads of taxpayers money
That's true now. It wasn't true forty years ago. Oh, nuclear fission was never the "too cheap to meter" dream originally touted, but it actually was extremely economical for a couple of decades. If you'd like to understand what changed, read this.

Re:Atomic Fantasy
If nuclear power was not regulated to death it would be quite cheap..... Not saying it should be regulated, but at the level they have it today is just ridiculous.. Like for the decommissioning where you have parts, with less radiation than other natural sources, are required to be stored and managed at huge costs.. Would be cheaper to just dump it in one of the old uranium mines and the radioactivity would still be less than from before it was dug up...
http://www.phyast.pitt.edu/~bl...
The second part is that it's almost impossible to get approval for any new, better, reactors that would be a lot safer and more efficient.
So.. Yea, it could have been almost that... But then oil/coal-barons started lobbying for more regulation because they saw it as a threat..

You could also try meditation. But as you occur to me to be an angry man: what about rock climbing? As soon as you climb (not in a hall obviously) you are one on one with your environment, does not really matter how difficult. You have only the rock, the sky the wind and if you are advanced enough to "relax" and "meditate" a bit while climbing: bees, eagles, falcons, swallows
... nature. When you are on top of your climbing route you will realize: for hours you have not thought about anything at all. Except for putting gear into the wand, moving forward, looking into the valley, at the sun, at the sky ... and realizing: it is just you. Regardless how angry you are, you can not fight the rock ...Probably it cures your anger and hate?

Re:FTFY summary
Perhaps no paradoxes, but it seems like discretizing time at least is a problem:
http://philsci-archive.pitt.ed...
Discretizing space leads to problems of Lorentz invariance - preferred frames almost universally exist in discretized spaces, and there always exists some transformation under which a non-trivial region of space is occupied by a low number of geometrical atoms (causal set theory tries to address this, but isn't really complete).

Re:It was that way
COSTS OF NUCLEAR POWER PLANTS - WHAT WENT WRONG?
A major source of cost escalation in some plants was delays caused by opposition from well-organized "intervenor" groups that took advantage of hearings and legal strategies to delay construction. The Shoreham plant on Long Island was delayed for 3 years by intervenors who turned the hearings for a construction permit into a circus. The intervenors included a total imposter claiming to be an expert with a Ph.D. and an M.D. There were endless days of reading aloud from newspaper and magazine articles, interminable "cross examination" with no relevance to the issuance of a construction permit, and an imaginative variety of other devices to delay the proceedings and attract media attention.
But the worst delay came after the Shoreham plant was completed. The NRC requires emergency planning exercises for evacuation of the nearby population in the event of certain types of accidents. The utility provides a system of warning horns and generally plans the logistics, but it is necessary to obtain cooperation from the local police and other civil authorities. Officials in Suffolk County, where Shoreham is located, refused to cooperate in these exercises, making it impossible to fulfill the NRC requirement. After years of delay, the NRC changed its position and ruled that in the event of an actual accident, the police and civil authorities would surely cooperate. It therefore finally issued an operating license. By this time the situation had become a political football, with the governor of New York deeply involved. He apparently decided that it was politically expedient to give in to the opponents of the plant. The state of New York therefore offered to "buy" the plant from the utility for $1 and dismantle it, with the utility receiving enough money from various tax savings to compensate for its construction expenditures. This means that the bill would effectively be footed by U.S. taxpayers. As of this writing, there are moves in Congress to prevent this. The ironic part of the story is that Long Island very badly needs the electricity the Shoreham plant can produce.

Re: I have said it before
Sure! And it only took 10 seconds of Googling to find. This book chapter explains how public hysteria forced the NRC to repeatedly tighten regulations, which drastically increased costs not only due to the sheer increase in materials and increased labor to design things to comply (what the author calls "regulatory racheting"), but also the need to repeatedly re-engineer things as the regulations changed mid-construction (what the author calls "regulatory turbulence").

fMRI
fMRI looks at what regions of the brain are active (by looking at which the rate at which different regions consume oxygen) and has been used to communicate with patients that can not otherwise communicate. First the patient is told to imagine two different activities (one at a time) like walking through a house and playing tennis. The pattern of brain activation is different for each thing but consistent between trials. Then, you can ask questions like "imagine playing tennis if X or walking through the house if not X" The results have been widely replicated. It has been widely used in MCS (minimally conscious state) but no reason it should not work in locked in patients. You can google it and find lots of article.

Re:five million gallons later, who'da thunk it
Nope, its 45MWe. As for the scaling, I live in Alaska where we have a coal cogeneration plant - I think it'd be nice and pollution limiting if it was nuclear, or at least nuclear supplemented.
Right you are, 160MW thermal 45MW electric, I'm getting too hasty on fact-checking. Still on the small side but perfect for Alaska, especially if your city or town is already piped for steam heating.
NuScale is projecting less than $5,000 cost per KW for these which is comparable to a recent utility sized 2010 capital cost estimate of $5,339/KW. In 2008 Moody's had really spoiled the mood by projecting $7,000/KW as the cost of new nuclear power and warning investors away.
So why is the capital cost of nuclear some 4-5 times the cost of a combined cycle natural gas plant (~$1,400/KW)? Aside from the obvious reasons like being dangerous and Atomic.
In 1970-71 Consolidated Edison built the Dresden plant for $146/kW
... still going today like an Energizer Bunny with ~1.7GWe. This is plant was built for ~50 times less than Moody's 2008 cost estimate.What the hell is going on?
I found no easy answers, but plenty to ponder in Chapter 9 ("Costs of nuclear power plants -- what went wrong?") of The Nuclear Energy Option, a great little book by Bernard Cohen [full text online]. This work is dated [1990] and quaint -- he is bemoaning a plant that cost $3,326/kW in 1986 -- the whiner! But he does a good job describing the NRC practice of "regulatory ratcheting", where standard numeric metrics of safety have been codified, all the tough work is over, and every succeeding generation of regulators gains a round of applause and gets to wear festive party hats if they just plug in new (always higher: click) numbers.
This is an example of what I call "No one ever lost their job" syndrome, a creeping cancer of our society on many fronts. It is a malady that especially affects safety cultures. No one ever lost their job by announcing that things are not quite as safe as they could be, or regulation is strangling essential industries. The NRC has created plug-in metrics like requiring more concrete, more frequent inspections, margins and limits, time-tables and reporting requirements. And heavier fines (announcing a hike in fines works even when there are no infractions or violations, the public imagines this is being done to punish evil corporations who are foaming at the mouth and straining on their leashes this very moment).
Then there is outright abuse and intimidation. The recent yarn, Uneven Enforcement Suspected At [US] Nuclear Power Plants which made my eyeballs pop out on springs when I read it. It seems to say that the NRC is concerned that regulation (by the NRC) might be lacking in some (un-visited) regions for unknown reasons and the NRC is
... crap, no I cannot even summarize it, it's so ridiculous. They are treating better safety record in some plants as something suspicious to be investigated. Then their 'suspicions' are released in a Senate report which the nuke-hysteria press predictably treats as some smoking gun. It should go beyond embarrassment. I feel some one should lose their job over this -- a regulatory agency releasing damaging speculation on an industry on a topic they are supposed to be sure of.But no one will lose their job, even when they susp

An example is in the USA with dozens of nuclear plants similar to Fukushima requiring active systems to shut down (and power) that are all at the end of their lives and which should have never been built. They should be shut down as unsafe and replaced with something safer (nuclear, fusion, solar, or otherwise), but likely will just be run longer until the next disaster.
With solar reaching grid parity (cheaper than grid electricity from coal,natural gas, and nuclear), it is hard to argue for nuclear without some huge design breakthroughs. It was hard even ten or twenty years ago when one could point to the solar pricing trends (but people scoffed).

Re:News just in
I suspect a lot of those extra costs are really due to China not having so many parasitic "horse judges" doing a "heck of a job" in the businesses involved with construction. I'm not suggesting that China is not corrupt, simply that the US nuclear lobby is vastly more so.
What the Hell are you on about? Nuclear power plants in America are expensive due to "regulatory racheting" and "regulatory turbulence". Ever-more-expensive requirements, moving goal posts, and frequent lawsuits and other interference makes large expensive projects into impossible and hugely expensive projects.
http://www.phyast.pitt.edu/~blc/book/chapter9.html
Did you seriously just suggest that USA nukes are over twice as expensive as Chinese due to corruption from the US nuclear lobby? *facepalm*
Since the Chinese government wants the power, those plants will be built, and the goalposts won't be moving during construction.
You mentioned corruption. In China there is a real problem with sub-standard materials and construction, with people being bribed to look the other way. If any nuclear plants ever get finished again in America, they will be expensive but safe. In China, who knows.

Re:In the absence of glyphosate
In the case of Roundup, a lot of studies have been done testing the danger to human health, and it seems to be no more dangerous than manure.
Well, there have been a lot of studies run by Monsanto that seem to show that. But then there are other studies that show links to Parkinson's and Autism, cancer, degradation of soil nutrients, as well as lethal effects in amphibians, and perhaps most alarming, a recent study found roundup in the urine of 44% of European Union citizens. Not only that, but it seems that it is actually many of the adjucts used in Roundup applications that are being shown to have the most toxicity, an issue most of the studies completely ignore by studying only the glyphosate, instead of the entirety of the compounds being used in such abundance.

I just have to challenge this
1). Any *blueprint* was never any further away than
1) FOAF network analysis
2) a signal splitter
3) the power to force your nation's providers to cooperate
4) a data warehouse
5) analysts.
6)??????
7) profit !I *really* don't think many nations needed the U.S. to tell them that.
So the *blueprint* point is totally false- the NSA did not provide a much needed but missing blueprint to anyone for any purpose
2) What nefarious thing has the NSA or US government ever done with this knowledge? Name one thing. As I see it, the US with all this data collection and the apparent restraint *to do nothing* with it, makes the US a provably good steward of the internet, almost better than we could have hoped for, given men and their nature.
I totally agree a despotic regime could emerge and would leverage this database in the process. I actually actively fear a Cheney or a Gonzales or a Rumsfeld or a Pipes or a Wolfowitz getting a hold of this kind of power.
That's why it's very important - VERY IMPORTANT- for the presumed demographic of slashdot to vote. b We're what keep the REAL fascists at bay.
I also think we need a provable, physical way (encryption / partial keys held by a number of judges? dunno..) to prevent the kind of leveraging of the chain of command that would permit neocons from gaining access to this database in the dark and use it against his political enemies
(I'll link to the specific thing the neocons did that has me so concerned at the bottom of this post)
Without the chain of command, we're fucked; it is a totally necessary part of any military.. But the chain of command + read/write access to this database means the power to potentially destroy who you want, in any way you want, for any reason you want and to distort reality itself to the intelligence community in any way you want. This represents a non-trivial, even existential and decidedly non-theoretical threat to our nation.

Not that many people can know or can get their minds around the full,ugly picture of all the trade-offs that reality forces on you. Those tradeoffs are analyzed, decided upon, get institutionalized, and finally become structural, procedural.Later, some regular guy working in the system looks at the fleshy details of what those trade-offs entail, and it appears callous and horrifying. They're just going to react out of a surfeit of humanity.

Re:Energy a bit more important than Beer
How about this quote from a review that was in Science Magazine, May 17 2013:
“Since the advent of hydraulic fracturing, more than one million treatments have been conducted with perhaps only one documented case of direct groundwater pollution resulting from the injection of chemicals,” said Radisav Vidic, lead author of the review and William Kepler Whiteford Professor and Chair in the Swanson School of Engineering’s Department of Civil and Environmental Engineering. “There is no evidence of groundwater contamination—even if it does exist.”

But the story as posted and linked is still essentially incomplete, because it doesn't mention what useful thing they propose to deliver. There has to be some beneficial payload in order to make this delivery system any use at all, assuming of course that it works as a delivery system.
The possible example of a 'payload' that you mention (not mentioned in the original article or links), for which you provided a separate link, is of something to down-regulate the production of protein(s) that induce cellular senescence in chronic wounds. This looks as if it could even be actually harmful if added to a wound, because the article you linked explains that the (natural) induction of this senescence restricts fibrosis in wound-healing. But, fibrosis "can be defined as the replacement of the normal structural elements of the tissue by distorted, non-functional and excessive accumulation of scar tissue" and gives rise to "many clinical problems" http://www.math.pitt.edu/~cbsg/Materials/Wound_Healing_Overview.pdf (such as keloids, hypertrophic scars, strictures and a whole list of problems). Thus, downregulating this senescence-inducing protein would be expected to increase the level of fibrosis in the healing wound, and to increase those problems: a harm, not a benefit.
There are plenty of technical 'solutions' around that might be wonderful if there was actually a problem of the right shape for them to solve -- read: they are of no real use because there is no useful application for what they might do. As pure science this one may have interest, but as a useful product, there's no sign here of that.

Re:Paradox!
That's very stupid. Hypothetical questions can have value, and if you insist on answering them all with "no" you lose that value. Here's an example taken from Albert Einstein; I've modified it somewhat, but the ideas are the same:
If I pursue a beam of light with the velocity c (velocity of light in a vacuum), do I observe such a beam of light as an electromagnetic field at rest though spatially oscillating? Yes, according to the Gallilean transformation, I would. However, there seems to be no such thing, neither on the basis of experience nor according to Maxwell's equations, so I deduced the principle of relativity.
If you insisted on answering "no" to his question, you'd get the wrong conclusion. Just because you can't get to velocity c doesn't mean the thought experiment is "outside the framework of Truth" (whatever the hell that means). This would all be fine if you simply accepted that an argument can have a truth value independent of its premises and conclusions. The argument "If all cats are dogs and all dogs are horses, all cats are horses" is true. However, the premises are false, so the conclusion does not necessarily follow from the truth of the argument, and in fact in this case the conclusion is false. I could write this more clearly in first order predicate logic if needed.
To be honest, you don't really know what you're talking about, your professors were probably annoyed by your smugness mixed with your stupidity--not the fact that you were right--and you should have been modded down, not up.

Re:"Earlier than expected"?
Studies are done world-wide of lake sedimentology and glacier ice chronology to better understand climatic and human activities over periods where historical records either don't exist or are limited. Have they been done in Peru? Yes. For example, this one deals with human activities over ~1400 years, and this one deals with sediment cores from Lake Titicaca and wet/dry climate cycles. This paper is a good example of how multiple studies from several sites can be combined together to better understand the history of climate change across a larger region (South America and the Carribbean). Lakes in arid areas are particularly interesting because they are so sensitive to changes in climate, so they get studied a lot.
There are additional citations in those papers, and if you search for "Lake Titicaca" "sediment core" and "climate", you'll find plenty of studies in the Peru/Bolivia area, but because most of what you've done is sneer at the idea that anyone could figure out anything about past climates, I doubt you'll really care. However, if other people want to investigate the topic there is plenty available. It is inevitably technical, but the basic principles are not hard to grasp with a bit of effort.

Re:Ruling out nuclear entirely may not be wise
A video you may like on India and thorium power:
http://www.youtube.com/watch?v=Nl5DiTPw3dkAnd I'm not going to disagree that in theory nuclear energy can be done as safely as most other big industrial processes (as long as the industry is focused more on safety and less on short-term profit maximization and the corruption of regulators). But even when that is true, the systems still tend to be more centralized than renewables, which has political implications.
"The Nuclear Energy Option" by Bernard L. Cohen is a great book you'd like relate to advocating for the safety of nuclear power with many good points; from one chapter (on improved designs):
http://www.phyast.pitt.edu/~blc/book/chapter10.html
"By the early 1980s it became apparent that a new conceptual design of nuclear reactors was called for. The cost of electricity from coal- and oil-burning plants had escalated to the point where their competition did not require maximum efficiency from nuclear plants. Furthermore, the added efficiency achieved by pushing temperatures, pressures, and power densities to their limits was overshadowed by the efficiency lost due to shutdowns when these limits were exceeded. But above all it would be much easier to satisfy the public's demand for super-super safety by starting over with a new conceptual design than by using myriads of add-ons to a design originally targeted on rather different goals. In the mid-1980s, several reactor vendors undertook these new designs. Let us consider some of the thinking that served as their basis. ..."But, back to the analysis on renewables. Thanks for agreeing that 3% works with your figures. But you have not addressed the point that you are sizing for the worst case month in a northern location. Remove your 4X worst-case assumption in sizing and you will get around the 1% figure I cited and you suggested showed I did not know what I was talking about.
:-)Solar levels are more constant near the equator, so clearly there you don't have to size at 4X there.
You say there is not "efficient" way to move heat, but as I said, you can store energy from the summer months or move it by embodying it in energy-intensive things like aluminum, liquid nitrogen, ground up rock, or you can make hydrogen -- so you can shift industrial demand from winter to summer. And most of energy use in the USA is for process heat and other similar things is by industry, not residential.
As I pointed out elsewhere, the state of the art in residential construction is not to require a furnace (with good well-insulated passive solar construction with air-to-air heat exchangers). So, energy efficiency at home is a better investment. Just passing new building codes would take care of most of that problem in thirty years with home construction turnover.
On solar PV efficency which links to land use:
http://en.wikipedia.org/wiki/Solar_cell_efficiency
"Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 40.7% with multiple-junction research lab cells and 42.8% with multiple dies assembled into a hybrid package.[7]"Again though, we use 50% of the land in the USA to make animal products that are mostly killing us (cancer, heart disease, etc.) and also polluting half our water supply while using up the other half (see "The Rave Diet"). So devoting 1% of our land to clean renewable energy, by contrast, does not seem impossible. It would even probably be a more profitable use of the land than agriculture.
What about energy storage via, say, compressed air in salt caverns is not "scalable" or proven?

Re:Cliche but nuclear is far safer than anything e
You make a good case, and you probaby would like this book by Bernard L. Cohen that says much the same:
http://www.phyast.pitt.edu/~blc/book/BOOK.htmlAlso, at some point, even with meltdowns, we can just site new nuclear plants where the old one melted down. So, Fukushima is now a good place to site more plants, as is Chernobyl, given the evacuations and the grounds are already contaminated. We could also produce synthetic fuels in those areas and ship them elsewhere. And we could build lots of robots to do the work.
Thorium reactors are even safer and we have much more thorium (thousands of years) than uranium and plutonium (hundred years?) for reactors.. But ironically it is said that thorium technology was not developed in the 1940s and 1950s precisely because it was safer and you could not make bombs from it.
With all that said, I'm still rooting for stuff like solar roadways, maglev wind, or the Rossi/Focardi eCat.
http://www.solarroadways.com/
http://www.maglevwindturbine.com/
http://pesn.com/2011/05/31/9501837_Cold-Fusion_Number-1_Claims_NASA_Chief/Even various forms of hot fusion are looking promising.
Although solar thermal could have done the job from the 1970s and on. Renewables IMHO have been cheaper than fossil fuels when you consider the externalities like pollution, health impacts, risks, defense costs, and so on.
http://en.wikipedia.org/wiki/Externality
http://en.wikipedia.org/wiki/Brittle_PowerOne can argue about the externalities from different nuclear options (such as who pays for the permanent evacuation around Fukushima or follow on effects like loss of agriculture or other economic problems in the area). If we do see a nuclear resurgance, it is going to look very different than today's plants (or should).
Conventional nuclear tends to be fairly centralized which has various political implications in a democracy. Yes there ideas like Hyperion, but they still probably require big central plants to make them and reprocess them. Mainstream nuclear in general requires a higher level of transparency then our society seems capable of on a sustained basis so far. Fukushima is just one more example of that lack of transparency or foresight.
Still, it's a bit of a chicken-and-egg problem, as if our society ran off of cheap thorium power, our politics might be better and less short-term if it assumed abundance instead of scarcity.
The good news is, we have lots of energy options, and the human imagination continues to invent more of them:

"JAPAN DISASTER: GE engineer says he quit over unsafe reactor design"
http://www.taipeitimes.com/News/world/archives/2011/03/17/2003498413Basically, it would seem like any reactor design that requires active cooling is unsafe and should be mothballed? Passive cooling ones like Hyperion or stuff like TRIGA is better.

http://www.phyast.pitt.edu/~blc/book/chapter10.htmlIn the robot capital of the globe as Japan is, where are the robots for nuclear cleanup? I helped a tiny bit with the Workhorse project for TMI (helping make a model mockup that helped get the contract):

Mother Nature can still really kick ass...
This calamity shows Mother Nature can still really kick ass...
And that's why we should cooperate more globally and not worry so much about fighting each other with all the advanced technology we have been creating. While this tragedy is horrible, just horrible, something like an asteroid strike on the Earth, a supervolcano eruption like in Yellostone, or a massive plague could kill billions. So, this should be a warning to our global society that we should cooperate more to prepare together for what Mother Nature can still dish out at random times.

http://lifeboat.com/ex/mainAnd by me:
http://www.pdfernhout.net/recognizing-irony-is-a-key-to-transcending-militarism.htmlLike with Hurricane Katrina where the USA lost a city, this event will be a test of the Japanese character. The good news is, you can see in Japan aspects of what a healthy society looks like (unlike the USA during Katrina or before). Japan prepared a lot for this (good building codes, to begin with). Their leadership has responded immediately. People are helping each other. News is being posted right away through their advanced social networks. (Many individuals wanted to help with Katrina, and were turned back, and parts of the New Orleans area descended into violence and fear...) You can be sure, as a society, Japan will come through this even stronger and healthier and better prepared for the next event. I wish I could say stuff like that about the USA these days? I don't know, even as I have a lot of faith in US individuals in a crisis. But in the USA, government is painted as the enemy. We don't know what good government would feel like anymore, sadly -- government that is accountable, or plans well, or prioritizes human needs over short-term profits to a few.
With that said, more money put into solar energy research in Japan is probably a good idea... And if you are going to have nuclear power plants, designs like Hyperion power might make more sense (ignoring how you still need reprocessing facilities that might be at earthquake risk). That plant design was 40 years old. This book explains why old nuclear power plant designs are riskier:
http://www.phyast.pitt.edu/~blc/book/chapter10.html
"The nuclear power plants in service today were conceptually designed and developed during the 1960s. At that time, it was deemed necessary to achieve maximum efficiency and minimum cost in order to compete successfully with coal- or oil-burning plants. The latter were priced at 15% of their present cost and used fuel that was very cheap by current standards. In order to maximize efficiencies in the nuclear plants, temperatures, pressures, and power densities were pushed up to their highest practical limits. Safety features were exemplary for that era, and even for current safety practices in other industries. But they were not up to present-day demands for super-super safety in the nuclear industry.
As the public became more concerned with nuclear safety, the Nuclear Regulatory Commission required that new safety equipment and procedures be added on, in the process discussed in Chapter 9 as "regulatory ratcheting." The amount of labor and materials for these add-ons exceeded that for the plant as originally conceived. With this added complexity, the plants became difficult and expensive to construct, operate, and maintain. Moreover, the level of safety was still limited by the original conceptual design.
By the early 1980s it became apparent that a new conceptual design of nuclear reactors was called for. The cost of electricity from coal- and oil-burning plants had escalated to the point where their competition did not require maximum efficiency from nuclear plants. Furthermore, the added efficiency achieved by pushing temp -

And example of small nuclear:
http://www.hyperionpowergeneration.com/Related case for nuclear power:
http://www.phyast.pitt.edu/~blc/book/Let's say, in a moderate worse case in Japan that 100,000 people die from some nuclear radiation accident and the clean up cost a couple trillion dollars. Nuclear power still might have been cheaper in Japan, all things considered, than coal which causes a lot of pollution and related illness.
Would it have been cheaper in that sense than solar and wind? Probably not...
Still, given this is the worst quake to have hit Japan in a century, and the nuclear plants are not being talked about as having total meltdowns, this event itself might prove how safe they can be in some situations.
Of course, dealing with direct terrorism intended to cause them to malfunction may be a different issue, but many major industrial facilities, like at Bhopal, have that risk. And ideas like Hyperion help reduce that risk. Ultimately, if we try harder to make our global economy work for everyone, we might have less fears that people will commit terrorism because the hate us because we support their oppressors for various reasons...

Here you go (energy task force case)
Took 5 seconds of googling. Here is an analysis of why he should have recused himself rather than writing a poorly reasoned "excuse" to stay on the bench:
United States Supreme Court Justice Antonin Scalia should be commended for writing an extraordinarily detailed memorandum explaining his reasons for refusing to recuse himself from a case in which his duck hunting partner, Vice President Richard Cheney, is a named party. The Sierra Club alleges in the litigation that energy industry officials were de facto members of the National Energy Policy Development Group (NEPDG), a federal energy task force chaired by Cheney, and that NEPDG’s records and minutes therefore must be made public pursuant to the Federal Advisory Committee Act. The statutory basis for recusal is 28 U.S.C. sec. 455(a), which provides that any judge “shall disqualify himself in any proceeding in which his impartiality might reasonably be questioned.”
