    Exelon must shoulder financial burden of its nuclear plants, BUSINESS, March 30, 2014, http://articles.chicagotribune.com/2014-03-30/business/ct-nuclear-plants-cub-oo-0330-biz-20140330_1_exelon-nuclear-plants-wholesale-power-prices

    A Tribune analysis has found that Exelon's six nuclear power plants in Illinois have failed to turn a profit during the past five years. Exelon, the Chicago-based parent of Commonwealth Edison, said it may announce plant closings. We asked Exelon and the Citizens Utility Board to address the future of nuclear power in Illinois: Over the last decade, Exelon has reaped more than $21 billion in profits, running a fleet of nuclear plants that benefited from high electricity prices.

    But thanks to a surge in natural gas supply and increased energy efficiency, wholesale power prices have fallen, and Exelon's business model isn't necessarily the winner it used to be. As a result, the company is reportedly threatening to close as many as three of its six Illinois nuclear plants, unless state legislators force consumers to pay more to boost Exelon profits and minimize its market risk. A bill that would insulate Exelon from the costs of its business decisions, while obligating consumers to pay the consequences, would be the financial equivalent of nuclear waste. Lawmakers should reject any one-sided proposal that causes this kind of fallout for consumers.

    … Negative Pricing means PAYING customers to use electrical power …

    Exelon weighs closing Cordova, two other power plants, Posted: Monday, November 24, 2014 5:13 pm | Updated: 5:13 pm, Mon Nov 24, 2014, By Dawn Neuses, Home, Q-C News, Local, http://www.qconline.com/news/local/exelon-weighs-closing-cordova-two-other-power-plants/article_e973036a-30e8-53bd-b32c-145537c65ee5.html

    During a Monday editorial board meeting with the Dispatch/Rock Island Argus, Richard Myers, senior vice president of policy development at the Nuclear Energy Institute, said the three stations at risk for closing are Cordova; Byron Generating Station in Ogle County, and Clinton Power Station in DeWitt County. Mr. Myers said nuclear facilities are several economic challenges, including little to no growth in energy demand since 2008, historically low natural gas prices, a congested power grid and energy policies that benefit renewable wind energy. At times, the Quad-Cities station is operating at negative pricing, said William Stoermer, senior communications manager for the Quad Cities station. He said the company won't make a final decision on closings until after next June, giving state lawmakers time to study the market and find solutions.

    Exelon CEO sees 69 percent jump in compensation, BUSINESS, By Julie Wernau and Tribune reporter | April 2, 2014, http://articles.chicagotribune.com/2014-04-02/business/chi-exelon-ceo-compensation-20140402_1_exelon-ceo-stock-awards-pay-package

    After buttoning up a merger with Constellation Energy, Exelon Corp. Chief Executive Christopher Crane saw a 69 percent hike in total compensation, raking in a pay package valued at $17.2 million last year. Crane — who sits at the helm of the largest owner of nuclear power plants in the United States — received the pay package including a base salary, stock awards, incentive pay and perks. He also saw an increase in the value of his pension in a year when the company slashed its dividend by 41 percent.

    In its proxy, Exelon said Crane outperformed his goals internally — the company performed better financially than expected internally, nuclear uprates were cancelled which strengthened the company’s balance sheet, its three utilities outperformed expectations and its nuclear fleet ran 94 percent of the time (its best performance in seven years).

    … privatized profit and socialized risk — the worst of all worlds …

    Exelon must shoulder financial burden of its nuclear plants, BUSINESS, March 30, 2014, http://articles.chicagotribune.com/2014-03-30/business/ct-nuclear-plants-cub-oo-0330-biz-20140330_1_exelon-nuclear-plants-wholesale-power-prices

    Exelon advocated for the same energy markets it now bemoans. And Exelon has opposed state support for its competitors' plants, suggesting that such aid illegally interferes with federal jurisdiction over power markets. Though Exelon asserts the virtues of competitive markets in its rhetoric, its actions suggest that what it really wants is privatized profit and socialized risk — the worst of all worlds for consumers. Yet it would be a mistake to assume that a deal would collapse simply because it's hypocritical. Exelon has political power.

    Watts Up With That?, The world's most viewed site on global warming and climate change, America’s Power Grid at the Limit: The Road to Electrical Blackouts, Guest Blogger / April 23, 2014, http://wattsupwiththat.com/2014/04/23/americas-power-grid-at-the-limit-the-road-to-electrical-blackouts/

    What industry pays customers to take its product? The answer is the U.S. wind industry. Wind-generated electricity is typically bid in electrical wholesale markets at negative prices. But how can wind systems operate at negative prices? The answer is that the vast majority of U.S. wind systems receive a federal production tax credit (PTC) of up to 2.2 cents per kilowatt-hour for produced electricity. Some states add an addition credit, such as Iowa, which provides a corporate tax credit of 1.5 cents per kw-hr. So wind operators can supply electricity at a pre-tax price of a negative 3 or 4 cents per kw-hr and still make an after-tax profit from subsidies, courtesy of the taxpayer.

    As wind-generated electricity has grown, the frequency of negative electricity pricing has grown. When demand is low, such as in the morning, wholesale electricity prices sometimes move negative. In the past, negative market prices have provided a signal to generating systems to reduce output. But wind systems ignore the signal and continue to generate electricity to earn the PTC, distorting wholesale electricity markets.

    Power Quality problems due to solar and wind energy GRID integration are increasing concerns.

    Power Quality Improvement for Grid Connected Wind Energy System using STATCOM-Control Scheme, IOSR Journal of Engineering (IOSRJEN), e-ISSN: 2250-3021, p-ISSN: 2278-8719, Vol. 3, Issue 7 (July. 2013), ||V6 || PP 51-57, http://www.iosrjen.org, http://www.iosrjen.org/Papers/vol3_issue7%20(part-6)/H03765157.pdf

    Long transmission lines are one of the main causes for electrical power losses. Therefore, emphasis has increased on distributed generation (DG) networks with integration of renewable energy systems into the grid, which lead to energy efficiency and reduction in emissions. With the increase of the renewable energy penetration to the grid, power quality (PQ) of the medium to low voltage power transmission system is becoming a major area of interest.

    Although the benefits of DG includes voltage support, diversification of power sources, reduction in transmission and distribution losses and improved reliability, power quality problems are also of growing concern. This paper deals with a technical survey on the research and development of PQ problems related to solar and wind energy integrated to the grid and the impact of poor PQ.

    Reactive power requirements should be applicable at the point of interconnection

    Reactive Power Performance Requirements for Wind and Solar Plants, A. Ellis, Senior Member, IEEE, R. Nelson, Member, IEEE, E. Von Engeln, R. Walling, Fellow, IEEE, J. MacDowell, Member, IEEE, L. Casey, Member, IEEE, E. Seymour, Senior Member, IEEE, W. Peter, Member, IEEE, C. Barker, Member, IEEE, B. Kirby, Senior Member, IEEE, J. R. Williams, Member, IEEE, http://energy.sandia.gov/wp/wp-content/gallery/uploads/ReactivePower_IEEE_final.pdf

    As variable generation continues to grow in capacity on the electric utility grid it is necessary to transition from the operational practice of reactive support being solely provided by synchronous generators. Advances in the technology used for variable generation has now provided them with the ability for voltage regulation and reactive support, compared to the older induction generators and line commutated devices. This paper presented an overview of the existing practices for reactive power support in the electric grid and provided a set of recommendations to changes in these practices that can be used by industry in order to transition variable generation from being a non-entity in reactive power support to being a contributor to enhanced grid reliability.

    The reactive power requirements should be applicable at the point of interconnection. Technical options to meet the interconnection requirements should not be restricted.

    appropriate scheduling of reactive power resources

    Reactive power reserve management: Preventive countermeasure for improving voltage stability margin
    Mousavi, O.A. et al, http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6343913&url=http%3A%2F%2Fieeexplore.ieee.org%2Fstamp%2Fstamp.jsp%3Ftp%3D%26arnumber%3D6343913

    Voltage stability imposes important limitations on the power systems operation. The system should be operated with an adequate voltage stability margin by the appropriate scheduling of reactive power resources and voltage profile. The main countermeasures against voltage instability are distinctly classified into preventive and corrective control actions. The management of the reactive power generation and its reserve are the main preventive actions against voltage instability.

    Alstom steam turbines will help GE expand in the coal-fired power plant market

    A Look At GE's Strategic Portfolio Repositioning In 2014, Investing 12/23/2014 @ 1:36PM, Trefis Team, Contributor, http://www.forbes.com/sites/greatspeculations/2014/12/23/a-look-at-ges-strategic-portfolio-repositioning-in-2014/

    GE is already a world leader in production and maintenance of gas turbines, but lacks in the steam turbine space. Alstom fills this gap well in GE’s portfolio, as its steam turbines are not only highly advanced but also have a large installed base in Europe. The acquisition of Alstom’s steam turbine business (that lies outside of France) will also help GE expand its presence in the coal-fired power plant market, which is rapidly growing in many regions of the world, especially China and Africa. Together, the gas and steam turbine businesses of Alstom constitute the bulk of its overall power business, which had $15 billion in sales last fiscal year.

    In comparison, GE’s power business constitutes the bulk of its power & water segment, which had revenues of $24.7 billion in 2013. So, the gas and steam turbine businesses of Alstom will add significant scale to GE’s existing power business. These businesses of Alstom are also profit making and have many long term maintenance contracts with power plant operators across the world.

  • At the risk of breaking into the flow & focus of this discussion (BD?, hydra-thrashing?, electro-inversion? –I tuned in late), this seems like the best forum for posting energy saving suggestions (which are cheaper than alternative energy and kills the economic viability of nukes just as effectively).

    * Some of us here appear to have standing and understanding which might influence the "deciders" of our power industries, but most of us can only manage simpler measures at home. However, millions of common sense economy measures CAN add up to reducing megawatt hours of electical demand.

    * While an efficient new fridge might be too costly, if you're running more than one unit, take a hard look at what's being stored inside. Often it's too old to remember, let alone eat. How about eating the good stuff, trashing the food poison/creepy stuff, taking a New Year's "fridge discipline" resolution, and shutting down your oldest unit (maybe the deep freeze?) and just using it for a storage locker. (Put long lasting jars of dried and vacuum packed food stuffs in there –with some desicant.) (Such measures mostly saves energy during the non-heating months, of course.)

    * Similarly, if you have more than one water heater, might one of them be shut down –or only used when needed? (If the water heater you choose to keep running is located inside the normally heated area of your home, it helps.)

    • I'll add my bit. :) Don't forget about the addition of sloped berming to create more insulation around existing house exteriors. For the cost of flashing up to the height of window frames and then using dirt to create the berms, much temperature buffering can be gained. Many people plan a pond at the same time and the removed dirt gets used for the berming project.

      Although my yard is completely flat with a 1930's era house, I'm fortunate to have a basement with thick foundation walls too. The temperature fluctuation down there is never as extreme as outside or my upstairs.

      I really encourage those who can afford to build new dwellings to check out all the beautiful owner built thermo-conscious homes these days. Straw bale types, cob, built into hillsides, papercrete….so much has been done and zoning regulations are slowly being changed in many areas to reflect these alternative and efficient building methods.

      • Hi Teri.

        I remember when bermed and hillside buried homes were the coming green thing, but when I toured such a model home –while well protected from our bitter cold Minnesota winters, I was stricken (almost literally) by the ventilation problem. It had a strong particle board, flooring glue, or whatever other "new home" out-gassing chemical odor.

        Since then, and often thanks to in-home Geiger counter monitoring, we've all become aware of the radon hazard –and the very mixed blessing of old basements –which too often need sub-foundation vacuum exhaust systems installed to reduce radon infiltration.

        * I'm sure buried homes can be done right: well sealed (a membrane) to the soil, a heat-exchanger system for bringing in fresh filtered air while conserving exhaust heat, air handling which maintains a positive plenum pressure throughout.

        * One might otherwise live in a well insulated (under the floor, over the ceiling, in the 2×6 studded walls) home which stands clear of the ground, screened against critters, but such that the wind can blow through under it. (Done right, with roller supports, I understand that such a home can also be made pretty much immune to earthquakes.)

        You might then want to build a separate combination, storm/tornado, wild fire, bomb and canning storage cellar near your house –well sealed to the surrounding soil and with a raised, sloped entry in case of a flash flood. (A mini-version of an underground home.)

        • Hi Craig, have you researched papercrete….it's a fantastic construction method that get's away from a lot of the off-gassing problems.

          I used to have all the books written regarding use of old tires for berming and was an early advocate until the off gassing issues were becoming more widely addressed. LOL! Jeeze, I even bought extra copies of the tire house books for my friends. Then my friends got into building with straw bale and cob methods. Now people are swinging to the advances and benefits of papercrete and impressed with all the beautiful choices of house styles….low tech production…how it performs. Lots of cool pics of houses and garden walls online also now, and climate specific advice too as the use and knowledge increases.

          I remember reading somewhere about 4' x 8' sheets being constructed in forms….as well as the usual "bricks" or sprayed applications being used. And unbelievable how much finished product the equivalent of ONE Sunday edition of the NY Times produced in a small batch (plastic barrel with baffles, home made, mixed via a vehicle axle set up).

          Insulative, extremely strong, long life, pretty cheap, insect and rot proof are some of the perks of papercrete building. A great way to locally recycle magazines, cardboard, newspapers too. Some folks stay away from using the *slicks* because of inks and additives in them…so a person can be picky when it comes to the paper slurry they make or check various recipes already in use.

          • * "Papercrete" is new to me (and thanks). Sounds like a good fit to our society –given the surplus of newsprint.

            * I often think about uses for things which accumulate as wastes –like your newspapers (from which I once made some horrible fireplace logs), plastics (which groups are melting down into machinable rectangular ingots), and the invasive scourge of "Scots Broom" that grows throughout my part of Oregon –which is quite oily –enough to be a wild fire hazard. I imagine myself touring about for free in a monotube boiler steam engine car, burning roadside trash and Scots Broom. (The exhaust might be a problem :-)

            • YW Craig. Plenty of that Scots broom around Bandon where I lived…too bad about the fumes it would probably give off because what a freebie presto log source, lol.

              Ya, I like how easy papercrete is and pics show using an elect carving knife to whittle in little display niches or trim to fit recycled car windows and other junk yard scores. Straw bale is ok but….much work with 3 layers of lime adobe coatings to seal and smooth inside and out. My one son did his lower story walls in bales between framed beams.

    Most large scale wind generation system output sections are power-electronic inverters, similar to small AC sources that plug into automobile cigarette lighters. Inverters face SEVERAL challenges in the operation of conventional AC electrical motors, such as invented by Nikola Tesla.

    AC Induction Motor Starting requires about 10X the full-load steady-state current. A MASSIVE (magnetizing inrush) current is required for on the order of magnitude of a millisecond. Then a short circuit current condition persists for several seconds until the motor winds up to rated speed for the existing motor-load condition.

    In order of effectiveness: 1 Synchronous motor/generators, 2 Wanlass Motor/generators, 3 Otto Smith Motor/generators, 4 Capacitor Start Kits, 5 Capacitor Banks, and 6 power electronic sources Can be employed to START AC induction motors: which are the DOMINANT Load of the AC Electrical Grid.

    • "WANLASS v. GENERAL ELECTRIC" –and a crowd of white-shoe attorneys to feed. They let the stakes mount up until there's enough in the settlement to make everyone a small fortune –if GE's bluff is called –if the little guy can afford to call it –if the little guy doesn't die of old age or jump out of a hotel window first. Corporations can outlast us all.

      Although I've briefly worked with small motors, traditional series wound traction motors, and tangentially with large AC motors, I'm embarrassed by how much I don't know about the many ways to build/wind motors and generators. I do appreciate your comments about the inrush of starting current, but is it safe to assume that any given load point is much less than 10% of a power plant's capacity?

      Of course, not exceeding the main breaker capacity is the look-out of the millwright –or whoever's on the consumer side of the meter/demark –and as moderated/throttled/browned by transmission line components, but it would be convenient if motors managed their own start-up requirements.

      Thanks for pointing it out, since I wasn't mindful that wind driven generators (of course) require somewhat fragile inverter arrangements in order to match line voltage, frequency and phase. But again: I suspect that any given start-up demand in a large load base is just a blip. (Or maybe I'm missing your point here.)

        Circuit Breakers for Motor Start Duty trip more slowly, by disabling the magnetic-trip function. The thermal trip function does not trip, when properly sized for the electric motor.

        Electric motors are distributed all over the GRID and at any given time, some percentage of them are starting. But once in a while, there is a regional disturbance; which causes a LOT of motors to start at about the same time. Wanlass electrical motor designs will help maintain GRID reliability with increased connection of wind & solar renewables.

        Whether this conversion to the 1970's Wanlass Electrical Motor Designs is first accomplished in North America, South America, Australia, Hawai'i, Europe, Africa or Asia is of little significance. In any event, the conversion is FAR OVERDUE.

  • * Okay, now I see your points –and I see that the Wanlass side lost ("laches and estoppel").

    * Since GE is selling motors with run capacitors and a second winding (if not across the board), some types of alternative motors are already "off the shelf" for demos and trials.

    Perhaps the best venue for your advocacy group to make presentations is in Germany, seeking the support of the Green Party and Siemens^ in particular. You'd at least not be totally bucking the establishment.

    I can't remember the name, but there's a major (THE major, I think) European/Scandinavian motor manufacturer you might also approach. (I'm aware of them because they were so quick to start using a certain patent, so they might readily adopt what our courts effectively put into the public domain, here in the states.

      Craig-123,

      Several years ago, my group TRIED to obtain OEM Wanlass electrical induction motors, all over the world. We contacted EVERY motor manufacturer that could be identified; with every type of imaginable.

      The Electrical Motor/Generator Cartel simply refused to produce ANY Wanlass 3-phase electrical induction motor designs, for ANY set of commercial terms and conditions.

      High Power Factor 3 phase induction motors do NOT require as many turbine generator sets. And the Turbine Generator bidness is THE global driving commercial force of the motor/generator industry.

      We, like my FRIEND Chris Wanlass, could only obtain rewinds.

      The FIX is global and total.

      In the English language, latches and estoppel means what I said earlier.

      The Motor/Generator defense was: the industry stole the technology and infringed the patent. But Wanlass did not CATCH the Industry Stealing in time, so the door was closed and locked to recovering damages. Before the Same Appeals Court, with the Same evidence and laws; and the same exact electrical motors, not just the same designs.

      General Electric, the electrical motor manufacturer WON the appeal; and Fedders the electrical motor CUSTOMER … LOST. This before the SAME 3 Appellate Judges in the SAME federal appeals court.

      And then the USA Supreme Court REFUSED to accept the case to resolve the Conflicting Rulings in the Same Federal Appeals Court, and the Same 3 Appeal Judges.

      The level of General Electric corruption, influence and control; is quite evident.

      Several major O&G firms and several Tier 1 academic institutions joined our attempt to mainstream the Wanlass Electrical Motor Designs. The FUNDING, backing and interest level was in place. The Wanlass Electrical Motor customers were lined up. Chris Wanlass electrical motor patents had expired; yet he still was willing to assist in this effort; for no personal financial benefit whatsoever.

      The turbine/motor/generator groups were COMPLETELY and OPENLY defiant to such market forces and academic standing. The financial interests and raw power of the Nuclear Village are clearly overwhelming. This political power is odd; given that the Civilian Nuclear Power project; known as the Atoms for Peace initiative LOSES MONEY; year after year.

    Engineers and musicians understand fundamental frequency, harmonics and subharmonics. So for example a guitar strign may be strummed to produce chimes. Any search engine for guitar chimes will produce hits on how to play chimes and higher harmonics on your guitar.

    http://www.guitartips.addr.com/tip132.html

    Play your bass E string open…this is called E, if your guitar is in tune : ) , or the Fundamental Frequency.

    Now gently lay a finger tip on the bass E string directly over the 12 fret. Don't press down on the string like you would do when actually playing it. This will take a little practice finding just the right place and pressure but find how to get the loudest note. You should hear something that sort of sounds like a chime. This "chime" will be one octave higher than when you played the string open and it is called the Second Harmonic. The note is still E.

    Now apply the same light touch technique to the bass E string on the 5th fret. You will now hear another E "chime" higher yet.

    Now lightly touch the bass E string on the 7th fret. You will hear a higher note B.

    Experiment around on other frets. You'll find other chimes as well. Pretty cool, huh?

    Do you notice anything else? Yes, the notes have less volume as you play higher & higher harmonics.

    This technique can be applied to any string on the guitar.

    The North American AC electrical grid operates at 60 Hertz; but higher frequencies, harmonic voltages (120, 180, 300, 420 Hertz) and currents are present. In some circumstances, subharmonics are also present (30, 20, 10 5 Hertz).

    These harmonics and subharmonics ALWAYS have bad effects; and sometimes the effects are highly destructive and even dangerous.

    Harmonics and/or Sub-harmonic frequencies can be created at the AC electrical Source, AC electrical Load, or along the way, by natural and/or anthropogenic causes.

    The third harmonic (180 Hertz) causes overheating in transformers and motors.

    The 5th harmonic (300 Hertz) creates counter-directional torque, which weakens the AC electrical motor output power (counter rotational horsepower) and can vibrate the motor to pieces.

    Sub-harmonics can mechanically destroy any connected equipment, much like the Tacoma Narrows Bridge was destroyed by a moderate wind of a particular velocity, in a resonant natural frequency mode. Films of the Tacoma Narrows Bridge collapse are readily available on the internet.

    Resonance and quasi-resonance are USEFUL, in some designs, such as antennas. The phenomena is exploitable; when that is the design intent. Unintended electrical resonance is destructive.

    Mitsubishi constructed uprated steam lines for two units of the California San Onofre Nuclear Power Station. Both of these power uprate steam handling designs exhibited DESTRUCTIVE resonance. One unit vibrated to the failure point and began to leak. The other steam handler exhibited accelerated aging from the mechanical resonance vibrations.

    We can reasonably presume that the San Onofre output up-ratings were preparation for MOX (plutonium enriched) nuclear fuel use. The litigation is presumably ongoing, but the San Onofre Nuclear Power Station is, if memory serves, decommissioned.

  • * Celebrating Tesla's invention of our AC power system is one thing. Signing on to some of his other showboat schemes is another. Had there been any significant development of wireless energy, the environmental consequences would have been catastrophic. Multiply today's EMF concerns by a billion or so.

    **Here's the take-home: the march of technological progress too often leads to our progressive disenfranchisement as citizens of a supposed democratic republic. We're ever more placed in a position of having to defer to the "higher" understandings of a "technotronic" priesthood –to tell us what's best for us, what's right and what's wrong.

    If the priesthood is paid by the Church, we're moving toward a theocracy. If it's publicly paid, we're becoming a technocracy. If they're paid by corporations, fascism is on the horizon.

    * Rousseau said: "It is the obedience to the wills of other humans, not obedience to the laws of nature, that threatens our freedom. It is liberating, I think, to remind ourselves that most of the technologies that a human being really needs to live an orderly, comfortable and healthy life are ancient."

    Check that knee jerk.

    I advocate philosophies, mores, technologies and disciplines –old, new, or yet to be invented, which are commensurate with our human dimensions, which would make enough sense to the average, high school educated adult that s/he could repair, replicate or make a device better/more appropriate.

    Eastern Europe could substantially reduce their energy conversion deficit, and improve their GRID reliability, and improve their balance of payments; by MANDATING use of Wanlass and Otto Smith electrical motor designs.

    Ukraine & their neighbors are caught in the crossfire between: the New World Order to the west and expansionism from Islamists, ChiCOMS and Russia.

    Improved energy conversion efficiency would help; to some extent.

    The AC grid requires instantaneous matching of sources and loads; wattage and reactive power (VARS) must each be in balance at all times.

    Wanlass electrical motors and Otto Smith electrical motors, if promulgated through the AC Electrical Grid, will substantially improve grid functionality. This is more desperately required with the rapid increase of Wind and Solar Sources.

    Americans Want America To Run On Solar and Wind

    Americans “overwhelmingly” prefer solar and wind energy to coal, oil, and nuclear energy, according to a Harvard political scientist who has conducted a comprehensive survey of attitudes toward energy and climate for the last 12 years.

    “The average member of the American public has the picture about right,” he said. “People have the relative harms about right. People have the relative costs for traditional fuels about right. They’re way too optimistic about [the cost of] solar and wind, and the caution is that if you inform them, you’re going to get lower support.”

    • Jebus: GOOD one!

      I corresponded once with Jeff McMahon. He strikes me as an honest wordsmith whose head is in good places –and this column of his attests to that.

      "Professor Ansolabehere found that even Americans who worry about climate change don’t support nuclear power. While such a result would not be surprising post-Fukushima, it surprised the engineers, who were envisioning a nuclear renaissance."

      Polling and effectively voting on NPPs versus alternative energy –is like going with the majority as to whether we should go around or just sail straight on into a looming iceberg. How absurd that our ultimate authority on such matters is fickle public opinion versus vested corporate interest flim-flam.

      How can corporations round up so much educated engineering talent to look us straight in the eye and say that NPPs are the way to go? Even Fukushima couldn't turn them around. What's it going to take, another disaster? Half a dozen? Nuremberg trials? Is there a learning curve at all for these guys?

      "[People are] way too optimistic about [the cost of] solar and wind, and the caution is that if you inform them, you’re going to get lower support.”

      Ha! No problemo! Just show them the inevitable monetary and morbidity costs of nuclear power –even without "accidents". Then factor in the now established rates for melt-downs and SFP cliff-hangers. Show them the bill!

  • Installment #2:

    * Some of us here might be able to influence the "deciders" of our power industries, but most of us can only manage simpler measures at home. However, millions of common sense economy measures CAN add up to reducing megawatt hours of electrical demand.

    * Yes: your next washing machine should be a durable front loader, but "for the time being", use detergent that's rated for cold water. (Hook both hoses to cold water so it will fill faster on the "warm" setting.)

    * Mercury vapor containing CFLs and fluorescent tubes are dangerous and become hazardous waste. (Read the EPA cleanup drill if one breaks! It's incredible that we've lived with fluorescent lighting for decades.) I'd at least keep them out of child play areas and out of the kitchen.)

    > http://www2.epa.gov/cfl/cleaning-broken-cfl#instructions

    In many instances we use far more lamp wattage than we really need, especially for work, dining and office areas. By adding a reflector/hood to a 40 watt incandescent lamp, and bringing it down to half the distance from your counter, table or desk, the working surface illumination can be like 300 watts. And for gosh sakes: lighting should only shine on what you're doing, never into your eyes. (Again: incandescent lights cost little to run during the heating season –obviously, so "lighten up" and chase away that "seasonal affective disorder".)

    I just don't know about LED lamps. I'm leery of the LED spectrum and industry propaganda.

      * Aside from materials being chemically hazardous, they can present enhanced toxicities by being processed into "nano" sized particles. Despite nano-tech being associated with advanced solar panel technology, the article didn't discuss that aspect.

      In any industry, it might be better and saner to sacrifice a few percentage points of efficiency in order to use safer and more common materials. That should also minimize the chances of your industry ending up being condemned –in the court of public opinion –something that nuclear and fossil fuel advocates would be quick to seize upon in the case of solar panels.

        Glad you enjoyed it!

        Interesting you would think of nano-tech, for me it was about cradle-to-grave, a head start as there will be millions of panels to recycle in the future. Keeping an open mind, and sticking to the highest standards will only help.

        I spent a few years on tech-gas support for a nano-fab facility.
        It is not far away, you will be able to drink 100's of processors/pc boards/cmos in a milkshake, and not know it.
        Not that you would want to, which you elude to.

        The materials used to create are extremely hazardous, simply due to their size. The tech is limited in part to the gases needed, they need to go from PPB to PPT. This is beyond difficult to achieve.

        I am glad to be done with that, creepy is a kind description.

    This is the future and end of nuclear power.

    Big solar step: Super-efficient system sets record
    The technology first achieved the record-breaking efficiency in outdoor tests in Sydney, Australia, and later at an outdoor test facility operated by the National Renewable Energy Laboratory (NREL) in Golden, Colorado, the primary lab for renewable energy and energy efficiency research in the United States.
    Lab-produced solar cells have even higher efficiencies than the 40 percent achieved by Green and his team. Earlier this month, the German-based Fraunhofer Institute for Solar Energy Systems ISE announced that it had developed a solar cell that can convert 46 percent of the sunlight that hits it into electricity.
    Green and his colleagues built their super-efficient system with commercially available materials, rather than with special, laboratory-produced photovoltaic cells. This helped keep the cost of the system down.

    and water friendly too!!! Solar photovoltaic power, which generates energy directly from sunlight, uses virtually no water. Six utility-scale solar PV plants were put online last year in the United States, according to the Solar Energy Industries Association (SEIA), a trade group.
    The U.S. wind energy industry, which generated 35,000 megawatts last year, and has been growing by more than 35 percent annually over the last five years, uses no water. The American Wind Energy Association (AWEA), a trade group, said in its annual report that wind generators prevented emissions of 62 million tons of carbon last year, and saved 20 billion gallons of water.

      Also coming online is energy generated from wave power that does not use fresh water. The country’s first utility-scale wave power project is the 1.5-megawatt wave energy park located 2.5 miles off the Oregon coast near Reedsport. It uses PowerBuoys, manufactured in Oregon, that move up and down with wave motion, causing an internal piston-like structure to drive an electrical generator.
      Solar thermal designs that focus sunlight on water to generate steam to power turbines eliminate climate-changing emissions. They also eliminate the need to produce coal, natural gas and uranium, all of which are significant sources of land damage, as well as air and water pollution.

    Stanford scientist unveils 50-state plan to transform U.S. to renewable energy
    Mark Jacobson and his colleagues have created a 50-state roadmap for replacing coal, oil and natural gas with wind, water and solar energy.
    February 26, 2014
    “…In recent years, Jacobson and his colleagues have developed detailed proposals for converting the energy infrastructures of New York, California and Washington states to 100 percent wind, water and solar power by 2050. The new plan includes an online interactive map tailored to maximize the renewable resource potential of each of the 50 states. Hovering a cursor over California, for example, reveals that the Golden State can meet virtually all of its power demands (transportation, electricity, heating, etc.) in 2050 by switching to a clean technology portfolio that is 55 percent solar, 35 percent wind (on- and offshore), 5 percent geothermal and 4 percent hydroelectric. Nuclear power, ethanol and other biofuels are not included in the proposed energy mix for any of the states….”

    Hahahaha… Brilliant "Angry Japanese utilities deny requests for more solar grid connections"

    The sticking point for the country's utilities, and why they began to refuse to add more solar connections to the electric grid, is they contend all that solar has created an oversupply in some parts of the country and is causing stress that could affect grid reliability.

    As of October 2014, five utilities said they would not accept more renewable energy applications until they could upgrade their grids to handle the influx and avoid blackouts. Some observers have argued that the utilities should simply invest in energy storage and other related technologies rather than refuse to accept applications for grid connections. Others have said the utilities are afraid that so much renewable energy will jeopardize their business models.

    What? Solar works? Cheaper for the end user? Risks putting utilities back in their place? hahahahahaha!

    • Yes(!) –solar and wind do work, plus they're not insane.

      But it is essential to keep these alternatives on a roll by questioning what we're handed to promote and defend. For instances:

      * What is the average home owner going to conclude if s/he has to hire both an electrician and a roofer to fix a solar paneled roof leak?

      * What happens to that investment when it's time to re-roof?

      * What about fire department reluctance to engage fires with paneled roof involvement –and growing concerns about that in the home mortgage and insurance industries?

      * What about the concerns some of us have with exposure to electromagnetic fields? Do you really want a high power DC-to-AC solid state inverter unit in your home?

      America is smitten by the culture of individualism. Is that why we take it as a given that distributed power co-generation by private home owners is a good thing? Why can't alternative energy projects be properly managed, engineered and socially constituted, invested in and subscribed to as co-operative projects?

      * Has the development and build-out of wump!-wump!-wump! bladed wind mill farms been facilitated by vested interests in order to sour opinion against renewable energy efforts in general?

      Not only are there many alternatives, there's no law saying that we have to choose the most efficient designs –over (say) the quietest, the most aesthetic, or the simplest.

    I remain optimistic that there is are numerous sources for power that we can rely on for the long term. Here is an example of power plant that produces very high efficiencies and can be adapted for use in many applications.
    http://aetherforce.com/electric-car-powered-by-salt-water-920-hp-373-milestank/

    "Unlike traditional cars that run on gasoline, the Quant e-Sportlimousine runs on an electrolyte flow cell power system made by NanoFlowcell that has the ability to generate an astonishing 920 horsepower (680 kW)."

    "This salt water powered car can go from 0-62 mph (100 km/h) in 2.8 seconds and has a top speed of 217.5 mph (350 km/h). The Quant e-Sportlimousine is built by the German company Quant."

    The problem that remains is breaking the stranglehold the oil cartels and nuclear cabal have on our future energy needs. The nuclear fuel cycle was the single most destructive decision ever made. Now there are many resources for nations and individuals to refuse power generated from nuclear and coal. One by one we will cut the cord of dependence.
