      Yeah, even when a nuclear power station's reactor catches fire and explodes, although it's pretty catastrophic, it's far from being a "we're all dead" moment.

      Chernobyl was a really badly designed reactor with no containment, and I've watched interviews with the people who had to pick up the bits of the reactor off the roof with their hands, made thirty years later. I mean, yes, it wasn't exactly good for them, but a good number of those who didn't die from the acute radiation poisoning are still about.

      As for Fukushima, well yes, nobody thinks reactors going bang is a good thing, but my understanding is that exactly one person died as a result of that, and this was from being crushed by a falling crane, or something similar. Nobody seems to be talking about the massive fucking tsunami that killed more than 15,000 people and caused those reactors to fail.

      And if we're talking about reactors that leak? Well Windscale (now Sellafield) did that pretty much all the way through the '50s, then caught fire, and there are still people living in Cumbria with the correct number of toes.

      Yes, nuclear has its risks, but so do most things in life. For example, burning coal causes radioactive fallout, and actually releases more radioactivity into the environment than nuclear power does. Because coal contains trace radioactive elements.

          there was very little warning about the Fukushima tsunami that caused the disaster. Only 2 employees washed out to sea suggests they were at least trying to take cover as best as they could at the time. My best guess is that those two were doing risky things to try and prepare and minimize the disaster (whether it worked or not). I mean they were literally at "ground zero" right at the coastline with a massive wall of water hitting them directly, one that destroyed the entire town (and so on). Mother Nature can REALLY be a BITCH.

        re Fukushima

        You're forgetting to mention the estimated cancer deaths for the Fukushima area. IIRC the estimate is 4000 over the 10 years after the incident.

        The estimate was something like 3999.95 cancer deaths over the same time period if the plant wasn't there, of course. (Not including side effects like additional radiation if lack of a nuke plant meant more burning of coal).

            Mushroom

            Re: re Fukushima

            No, the cancer deaths from the coal station are significantly worse, due to inhaled nanoparticulates, as well as radioactive material contained in the millions of tonnes of coal burnt, which dwarfs any (normally functioning) nuclear plant emissions.

            Yes of course there was a detectable increase in radiation after fukushima (the thing about radioactivity is, it is so easily detectable in the tiniest quantities, yet not at all harmful in those quantities) but the particulate emissions and chemical spills from more traditional industries are much more harmful, but not so easily detectable.

            As AC said, the cancer rates are estimated to have increased by a factor of about 0.05 in 4000

            There is a huge amount of fear around nuclear power - partly because people are so terrified of nuclear weapons and don't understand the difference between 1) a supercritical nuclear bomb blast, 2) a 'critical' controlled reactor, 3) 'subcritical' fissile material - the highest level of 'nuclear waste', and 4) radioactive but non-fissile material, as leaked from fukushima but also occurs naturally everywhere.

            But partly also I think, due to vested interests (oil) who can make huge profit by spreading anti-nuclear FUD.

            This FUD of course pushes up the cost of nuclear, which then adds to the anti-nuclear argument.

          Sure it is. Offer a 10,000 pound/dollar/euro bounty to any male who has a vasectomy after having one child, or 20,000 to any female who gets her tubes tied after one, with half bounty after the second child and no bounty after #3. Further, no tax breaks or welfare increases for more than 2 children. Government also covers the cost of the operation regardless of number of kids. Then, ban reversals. This slows the rate of birth considerably, without preventing anyone who wants a large family from having one. It would save more in welfare than it would cost as well. The huge incentives that decrease with more kids, hitting negative money with 3 or more, would drive a lot of people to getting snipped.

          Getting snipped is worth it even without the government interference. I was chopped after child 2 and sex after that was just fantastic! We just get after it when the mood strikes us, without worrying about plastic baggies or whoopsies. With careful investment and only raising 2 kids, our net worth is 7 figures and growing, part of which was the cost savings of not buying birth control over the decades.

            China is a good example of a government deciding how many children you're allowed to have, and you see how well it went since they had to back down after some time, and that despite not being the most touchy-feely government out there.

            An admirable concept. It's a pity though, that surging population growth is not a problem in most western countries - the UK population (if you ignore migration) is actually ageing and thus declining (which is why we need more young healthy workers to pay our pensions and no sane government has ever actively tried to limit migration in any meaningful way until we got the current shower). Real runaway population growth is in places like India, China and a multitude of south east Asian, African and South American countries where the necessary amounts of spare money isn't exactly sloshing about.

      I actually just assumed that the stuff about nuclear power was hyperbole... for comedy.

      But seriously it's like anything else that is potentially toxic, from the rare earth stuff that make LCD panels and efficient solar cells possible, to the lithium in high efficiency batteries (halt and catch fire?) to the industrial chemicals needed to etch circuit boards and make those silicon wafers that get turned into cell phones. Some of that stuff (like cyanides and flourides) are EXTREMELY toxic and dangerous outside of the controlled environment.in which they are used and it is my understanding that a LOT of recycling goes on (to avoid dumping toxic waste AND be more economical in the long run - win win).

      My point is not to scare people. My point is that these industries have safety standards they must adhere to, just like nuclear power plants, which means that inevitable accidents are few and far between (and neither the planet nor human population has been killed by these infrequent accidents). The solution is intelligent application of basic safety and attention to important details by operators and management.

        The article says each algae cell was about the same size as a AA battery, so if that's stood on end it takes up about 1cm² of floor space. So a GW of them spread out on the ground (to make sure they still get light) would be 10¹⁵ cm² (100,000 km²), or a square about 316km along each side.

          a simple derivation: a solar panel of one square meter can generate about 200W of electricity in good sunlight. I bet this is WAY more space-efficient than a tub of BG algae... just sayin'.

          And a typical electric car might require about 10HP for cruising on the highway which would be around 7.5KW. City driving may require even more (on average, even with dynamic braking). So 2 hours' worth of battery is around 15KWH (at the least, let's say), after which you will probably need a charge. Now how many square meters of solar panels do you need JUST to charge the car? (and it has to be during the day - when you are WORKING and DRIVING - in order to be of practical use). And if EVERYONE at your company, or the store, or your apartment building, wants to charge THEIR cars TOO...

Often I do not have time to take 2 years' worth of classes nor 8 hours' of online frustration searches to understand what it means, but if I try and put myself into the mindset of the people that use this kind of math (like statisticians, for example) that SOMETIMES I can "get" what they are doing well enough to create a computer program that analyzes data "that way". Last time I did that was with some averaging method that was being used for ocean wave analysis when suddenly realized that their equations were actually expression values in terms of data sets and the equations that described them, then doing algebra and whatnot wiih equations instead of variables. Then it was like "OK then I guess THIS is what they're doing" and some pretty good results emerged.

    "some of the daylight that the sun carelessly drops in our direction and is just going to waste"

    Not exactly going to waste. The 'daylight' would otherwise fall on the surfaces that the PV panels cover up, warming them, and even causing plants to grow. Granted that the PV converts energy into a form we find more convenient, but the concept of 'waste' in this context seems rather narrowly western-urban-ethnocentric for comfort. As a parallel, a Cambridge physicist calculated a few years back that, given the typical density of UK housing estates (20+ dwellings per acre), geothermal heating would not work except for the few, as there wouldn't be enough to go round.

    What we really have to do to sustain our own future as a species (the planet itself being much more robust than we are) is to abandon the concept of growth being the primary indicator of achievement. Granted, it's the measure 'used' by all life on the planet but the gross impact of all other species is curbed by inherent limits such as dying out by the ton when resources dry up. Our fundamental difference is that we're so darned adaptable that we have so far sidestepped such natural controls. Consequently, we have to start thinking differently - not 'going back to nature' in this respect but striving to overcome the 'natural' drives and patterns of behaviour. Locusts can only operate the way they do because they're hard wired to do so. We have the capacity to abandon the evolutionary hard wiring, and it's long overdue that we did.

      Might have been for currently 'easily-available' geothermal. If we can develop the technology to drill about 5km+ deep, there's more energy than we can ever consume, everywhere in the world.

      "abandon the concept of growth being the primary indicator of achievement"

      Very absolutely this, and triple thumbs-up. Closely related is using GDP as a measure of "what must always grow". GDP says very little about either wealth (since it's divorced from purchasing power), nor about quality of life (since it doesn't take account of any other factors than strictly monetary). The main advantage of using GDP is that it's easy to calculate. In other words, just like looking for your lost keys under the streetlight is easier cos there's more light, even if you lost your keys somewhere else.

      eventually, ALL solar energy turns to heat. Electricity, work, waste heat, friction, you name it - all become heat energy, eventually. 1st law of thermodynamics. The energy of performing work is applied to it in order to overcome some form of friction or resistance, which creates heat. Even your computer gets hot when it computes. Potential energy even becomes heat once the potential is released. Solar power from BG algae is no different, and BG algae growing eventually turns into rotting mass after it dies, which releases heat as bacteria eat it.

      Kinda like that. So making and then using electricity out of Mr. Sun's rays still creates heat, in about the same amount as if it had not been made, over time.. Energy in = Energy out, in one form or another.

      "Will all the offshore wind farms they're building on the East Coast of the UK have a significant effect on onshore wind speeds? "

      Some much cleverer people than me have worked out that there is a theoretical 30% efficiency limit on turbines. So at most they could take out 30% of the wind power even if they occupied 100% of the cross-sectional area the wind passes through. Given that in practice most wind passes above and below turbine blades, and there is a lot of space between turbines, I would say that the turbines themselves occupy far, far less than that.

      Also, the wind energy is constantly being replenished by solar heating of the atmosphere, sea and land at different rates to each other and in different locations, so it's not going to run out any time soon.

      Short answer, no.

        Indeed. I know we're talking about wind turbines so we should fear and hate them (they're green!), but you'll have to admit their wind resistance is way smaller than that of an average building.

        So, did building Manhattan have any noticeable effect on the general climate of the state of New York? That thicket of high rises certainly blocks winds more than any wind farm ever could... (Replace by any big city in your own area, they all tend to be full of buildings.)

    time crystallography

    Semiconductor crystals are useless until you introduce lattice irregularities such as impurities. Similarly, a useful time crystal must hiccup irregularly in order to be useful. It is at those hiccup points that we open our eyes and take a peek. Indeed, the act of doing so is what causes the crystal to hiccup, thus making it useful. Use it or lose it.

    Of course, that's quantum time crystals. Macroscopic time crystals have existed for many years. They are the TV channels that only ever show repeats...

    Well

    The Many Worlds theory implies that all possible universes are ... possible. Probable even. So it's likely that another universe exists in which our universe is a computer simulation.

    If our universe were a simulation in a computer, it would explain a lot of things. For instance, a quantum particle doesn't have to make up its mind until someone performs a read on the location. It would also explain a minimum resolution (Planck length) and clock speed (Planck time). It would also explain why, in regions with a lot of stuff, the calculations slow down because there is more crunching to be done. This explains relativistic time dilation. It explains the speed of light - how quickly signals can propagate across the simulation.

    I'm assuming that the simulation runs in a container or a VM. If we could break through to the host or bare metal, then we would have incredible power - time crystals and the like.

    Why Nuke Plants Are A FAIL

    1) The best nuclear plant designs, some of which are decades old, are never even considered because: They cost more money than the unsafe, guaranteed-to-fail designs. IOW: $$$$$$$

    2) The best solutions for dealing with nuclear plant waste, some of which are also decades old, are never even considered because: They cost more money than shoving the problem off on someone else, specifically the future generations of mankind. IOW: $$$$$$$

    There ARE guaranteed safe nuclear plant designs and safe, realistic solutions to nuclear waste. Not a single proponent of building new nuclear plants gives a rat's that they exist. They only want to build the cheap crap that are guaranteed unsafe and ignore nuclear waste. Examine every plant design proposed by nuclear plant proponents! Examine every nuclear waste solution, if any, by nuclear plant proponents!

    Until humans get realistic about solving (1) Nuclear plant safety, and (2) Nuclear waste, Nuke Plants Are A FAIL.

      your "rules of engagement" are one-sided. Otherwise I could easily prove you wrong.

      Truth: given the economic potential of waste recycling and nuclear plant operation, many power companies would LOVE to build more plants and recycle nuke waste. It's just that political protests, malicious lawsuits, corrupt and ignorant politicians, and government regulations PROHIBIT THEM FROM BEING PROFITABLE.

      And it is not a 'safety vs unsafe' issue either. Any company that wants to be profitable has managers and directors that realize the importance of safety on employee retention, public image, AND profitability in the sense that good safety means more profits, happier employees, and better chance at success. And also, there would be no need to settle all of those wrongful death claims, injury claims, equipment and property damage claims, and other legal problems that negligence and lack of safety can cause.

      "IOW" corporations are run by people who are not inherently evil. They just want to make money, for themselves, and for their investors. Who wouldn't?

      But these points fall outside of your rules of engagement, so I am sure you will not consider them.

    On the dynamics and evolution of some sociotechnical systems, Elliott W. Montroll, Bull. Amer. Math. Soc. (N.S.) 16(1): 1-46 (January 1987).

    pp 38-39

    "On December 2, 1942, Enrico Fermi and his colleagues produced the first sustained fission chain reaction, demonstrating the feasibility of a nuclear power plant. By fifteen years later, the first commercial nuclear power plant was operating.

    The highly successful space program was initiated only a few decades after primitive rocket experiments. Robert Goddard's first success in shooting a rocket over a mile vertically was achieved on May 31, 1935; twenty-six years later the Soviet cosmonaut was the first human to encircle the globe in a rocket-launched satellite.

    The record of these successes has led the public, and even numerous scientists, to believe that with a little money and ingenuity, any desired scientific goal could be achieved. Unfortunately, this is not always true. Consider the magnetically confined fusion program which started as Project Sherwood in 1951. ...

    ...

    I contend that the magnetically confined fusion program has fallen victim to the tyranny of many dimensionless constants. The great engineering successes of the past have involved processes which could, to a first approximation, be characterized by a small number of dimensionless constants. Hence only a small number of model experiments were necessary to determine the feasibility of a project and to estimate the cost and difficulties to be surmounted. Even the space program was broken down into a number of subprojects, each of which could be analyzed in terms of a small number of dimensionless constants so that the results of many independent model tests could be used as a basis of the required full-scale engineering designs.

Crystals have resonance, and if you whistle at the tone of a bell, it will start ringing (this is how radios work by the way with resonant electronic circuits receiving broadcasts).

      I have often speculated the possibility that human thought and observation are directly related, and if M theory is correct, that same thought+observation energy must go someplace to create the new parallel universe whenever a (significant) quantum potential is observed. I suspect it goes to its own separate dimension, the "n + 1'th" dimension, one which separates THIS n-dimension reality from the other (theoretical) n-dimension reality(ies) based on the observations of one or more living beings that have thought energy. Or something like that.
