In the Marshall Islands. Here's the money quote from the abstract of a paper
on the continued "unsafety" of living on the former nuclear test site:
Measurable excess radiation could be expected from the decay of 137Cs produced by the US nuclear testing program there from 1946 to 1958. These recordings are of relevance to safety of human habitation and resettlement... and relatively high gamma radiation on the island of Bikini (mean = 184 mrem/y = 1.84 mSv/y)... the standard agreed upon by the United States and the Republic of the Marshall Islands (RMI) governments (100 mrem/y = 1 mSv/y). External gamma radiation levels on Bikini Island significantly exceed this standard
Meanwhile, external gamma radiation levels on the beach at Guarapari exceed 53 μSv/hr
( > 460 mSv/yr), and the international radiation protection community says nothing.
Everyone should be allowed to go back home in Chernobyl, in the Marshalls, and in Fukushima. Right now. This is insanity.
District heating has been big in the Big Apple since the eighties... that is, the 1880's. The whole island of Manhattan is cris-crossed with steam pipes which occasionally make the news.
On a whim, I tried to find the price of steam in Manhattan. I was somewhat surprised when I found it. Steam goes for about $31 per thousand pounds
, and each pound carries about 1200 BTU of energy. This comes to roughly $26 per million BTU, or a bit under $25/GJ.
NuScale doesn't give the output conditions of the steam from its reactor, but it does give the turbine throttle pressure: 475 psia
. This yields a minimum temperature of ~462°F (239 C). ConEd distributes steam at about 165 PSIG and 358°F
(which has to be a typo, as this temperature/pressure is compressed water; real temperatures would be slightly superheated at 375°F or more), so if the NuScale was used for district heating there's some room for a topping cycle to drop the steam pressure.
The NuScale boiler inlet water spec is 300°F; assume 500 psia: h = 627.7 kJ/kg. Steam at 475 psia/275°C (reasonable PWR SG outlet conditions) has h = 2946.1 kJ/kg, Δh = +2318.4 kJ/kg. Dropping this to 180 psia/saturation yields h = 2784.9 kJ/kg. (I did not check the entropy to see if the steam would still be superheated.) Δh = -161.2 kJ/kg. Roughly 6.9% of the input heat is convertible to work even if high-pressure steam is tapped off for district heating.
6.9% of 160 MW(t) is 11.1 MW, which is more than enough to cover the NuScale house loads of about 2.5 MW per unit.
Assuming up to 145 MW(t) of steam output, this comes to 522 GJ/hr with a value in excess of $12,500 per hour. If this can be sold at 30% capacity factor, revenue from heat sales would be on the order of $33 million/year. A NuScale unit selling for $6/W(e) installed would cost $285 million; $33 million/year in heat sales alone would be a greater than 11%/year return on investment not including electric output.
If New York could be gotten off its paranoia over nuclear power, this could be YUGE.

Short item at Nuclear Street
The BAS just published a guest piece by one Steven Starr
, among whose howlers I pulled this gem:
many individual pools contain more cesium-137 than was released by all atmospheric nuclear weapons tests combined. These utterly lethal radionuclides will require some form of supervision for hundreds of thousands of years....
Clue for you, Steven: Cs-137 has a half-life of 30.17 years. Roughly 90% of it disappears every century. In 3 centuries spent nuclear fuel is so low on gamma-emitters that it can be handled with gloves, and in 5 all the Cs-137 and Sr-90 are effectively gone and the spent fuel has LESS activity than the raw uranium ore from which it came. What remains has such low activity, and most of it alpha-emissions, that you're probably more at risk from heavy-metal poisoning than radiation if you eat it. Those risks are pretty low, too; the "UPPU" group who got significant body burdens of plutonium through accidents show no related ill effects.
If physicians actually wanted to be socially responsible, they'd learn something before spouting off. It's a pity that this guy is a senior scientist and not a physician, otherwise it might be possible to charge him with malpractice and get him out of the fear-mongering business. Sadly, PSR is just a front group for well-heeled anti-nuclear interests; if they were subject to real medical and scientific discipline, it might be possible to make them ACTUALLY serve the cause of social responsibility.
Atomic Insights has what appears to be a new Green troll. He dredged up the tried-and-discarded concept of shrouded wind turbines from a post at NBF
. Such ignorance deserves derision, and I gave him some:
Check this out.
Oh, look, a rehash of a concept from the 1970's that went nowhere then for the same reasons it is still going nowhere. It's a huge fixed structure that will collect hundreds of tons of ice in winter storms and can't be feathered against high winds. It's still subject to the Betz limit and can't generate wind when there isn't any.
(NB: wind turbines with shrouds and diffusers are a very
old idea, older than nuclear power IIUC.)
How would the Johnny come lately nuclear community/industry rebut this?
Perhaps you should ask the people at the dawn of the Industrial Revolution why they thought coal-fired steam engines were so great when they had wind for free; you might learn something.
Why would Japan or Asian nations — or we — continue nuclear plans or startup now?
Why would any serious movement recycle BS concepts that they KNOW cannot work to actually eliminate fossil fuels, unless they are secretly working to protect fossil fuels?
Licensed reactor operators at Tennessee Valley Authority's Watts Bar Unit 2 project reached a major milestone at 2:16 a.m. EDT, Monday when the unit's reactor achieved its first sustained nuclear fission reaction.
Also known as achieving "initial criticality," TVA says Unit 2 is now generating heat under its own power....

The site administration for The Energy Collective is not doing its job. Perhaps it is not competent to do its job. Regardless, a simple matter like users unable to log in should be responded to and fixed quickly, right?
Not really. I'm logged into Wordpress, but on TEC I get this:
So, it claims I'm NOT logged in, but when I click the login link I get this:
Two complaints to email@example.com have neither produced a correction nor received a response. (Neither have any previous complaints.)
At this rate, it won't be long before the site is history.
Edit 4/28 19:20 EDT: After the firewall problem was fixed there was ANOTHER problem, but that finally got fixed too. However, this suggests that things are not tested before going to production. That is going to bite badly... again (like the HTML conversion debacle and the continuing failure to support list tags).
The Energy Collective was recently taken over by Energy Post. This didn't have any visible consequences until just a couple days ago, when Energy Post attempted a conversion of the site from Drupal 6 to Wordpress.
I've been using Wordpress for years, and had no real complaints about it. But this conversion... it was like having the Library of Congress edited and reprinted by Mad Magazine. EVERY BIT of formatting in copied posts and comments was completely stripped out. Not just blockquotes and lists, but bold and italic tags were removed—irrecoverably, I was told. Here's what I put in the "new look" thread
I couldn’t find this post in the last 10 screens of old posts (which took a VERY long time to sort through) so I wound up posting it in the newest post also. I only re-discovered this because it wound up listed in the new comments.
Among the problems we now have:
1. List tags aren’t allowed. Not flagged, just stripped without notice.
2. ALL hyperlinks to previous posts/comments are defunct, 404. Nobody thought to implement redirects for them.
3. ALL formatting has been stripped from the copied-over comments. Indents, italics, things distinguishing quoted material from new text… stripped, and vast amounts of intelligibility utterly destroyed in the process.
4. The link to change to “oldest first” sort doesn’t work.
5. Comment hyperlinks are now harder to use than under Drupal. Instead of simply having a link, one must (a) click the “link” icon, (b) click inside the box that appears, (c) select-all and copy (3 keystrokes minimum), (d) click in the address bar, (e) right-click and then FINALLY (f) select “paste-and-go”. Whoever came up with this should be removed from all administrative roles, effective immediately. It is beyond outrageously stupid, it is malign.
6. Worst of all, attempting to use the permalink on an only comment (first in the thread) did NOT link to the comment, but the “respond” box! I was able to get the correct comment link using Domain Inspector (the comments section is not included if you “view page source”), so it’s obviously available to whatever generates the page and SHOULD be used to make a straight hyperlink.
7. Comment edit box is way too small.
8. Comment notification box is checked by default, doesn’t remember previous un-checks.
I strongly suggest that comments be closed, all comments made under WordPress mailed back to the commenters with the URLs of the discussions where they were posted, and the conversion re-done PROPERLY once the admins have figured out how to fix the conversion issues.
(shortly after this, a host of expanded HTML options were enabled in comments. Not before.)
I was told this could not be fixed
1.Formatting is allowed on all new comments. Legacy formatting was not possible without checking and hand coding 50,000 comments.
2. External URLs remain where they we’re coded in full.
3. Formatting, See 1.
4. Sort function works for all new posts, there may be issues with legacy articles for reasons discussed above
5. Linking is possible, it may take 2 more clicks.
6. Comment Box – the box is designed to be typed in to and expands as you type. If you copy an paste and essay in to it you can use the Cursor Keys to navigate through the text. On first press of the cursor key the box will enlarge to show the full text.
7. Comment notification is now un-ticked as default. Legacy data of’ un-ticking of box’ was unable to be retained. There is however a new Subscribe feature.
There are also new features that let you search the comment box by Authors or text. You can now embed Video and there is a new feature that lets you attach files to your articles e.g. a pdf on the benefits of Nuclear Power.

I was not alone in my negative appraisal of the quality of conversion; Willem Post had this
I made a reply which was removed and returned to me by e-mail:
the database was in a very bad state, which caused endless problems with the conversion
The problems I'm talking about have nothing to do with the database, but with slipshod conversion of the HTML of comments. It was certainly possible to do better, because I now see almost all of the formatting options that were previously missing at the top of this edit window. But someone was sloppy and got all of that lost in the mis-translation. Unless someone was criminally sloppy, the scripts used to read the Drupal database and do the conversion are still there. Minor tweaks will fix the (documented!) HTML issues. Just do it over. Speaking of documented issues, the stylesheet hid part of the width of the right sidebar with an opaque gray overlay, looking like this:
I got a defensive and hostile note attached to it:

Please note I removed your latest comment because I find it offensive and rude.
We do not tolerate offensive comments on The Energy Collective.

(does this guy have a thick enough skin to be running a major website? does he have the competence to recognize when things are going wrong? he's sure not scoring any points with the people whose oxen have been gored.)
This was already very bad. But it got worse.
I like to book-mark the most recent comments in comment threads so I can return to them and scan for newer additions. On Tuesday, I believe, those bookmarks ALL stopped working. I can go to individual discussion threads, but links directly to threads or individual comments are re-written and sent to personal profile pages (mostly my own). For instance, whether I click from my bookmarks or paste in the address bar, this:
gets re-written to this:
I have complained to firstname.lastname@example.org, with no replies and no fixes. There's certainly plenty of desire remaining to fix these problems and get everything spic and span again, but that all will and energy appears to be OUTSIDE the administration of Energy Post. The insiders refuse to admit that there are any problems, let alone ask for assistance in fixing them or explore possibilities. (This is what I'd expect if it was being run by a few tyros who are in way over their heads, especially the violently defensive reactions to practically all criticism.)
It is now between painful and impossible to follow and participate in discussions on TEC; for all intents and purposes, Energy Post has destroyed The Energy Collective. Worst of all, Energy Post management will not even admit they have a problem. There appears to be one last, sad snapshot of the site at the Internet Wayback Machine
, but that may be all that remains of this once-valuable forum.
Here is an example of how the technical staff have broken links into TEC. I bookmarked this URL, where I was having a discussion on the Drupal version of the site:
This URL no longer exists, and there is no re-direct; it now comes up 404. The Wordpress copy of the article appears to have been at no less than 2 URLs, and it now comes up as this:
Why the gratuitous change in URL? I have no idea, and the staff aren't talking.
Nothing suggests mental illness more than the tortured reasoning used by anti-nuclear activists to attempt to justify their positions. Often they fixate on particular claims which turn out to be utterly ludicrous after even shallow examination. One of these is the argon-41 chromosome-damage "theory" currently being flogged by BasG
(Bas Gresnigt) over at Atomic Insights. This short-lived isotope (half-life 106 minutes, beta-decaying to stable potassium) is a noble gas, and disperses rapidly in air by diffusion and turbulent mixing. The "researchers" who tortured their data to make it confess the crimes of 41
Ar got it to sign a statement amounting to this:
- Spent nuclear fuel emits neutrons due to spontaneous fission.
- The neutrons escape into the air and run into 40Ar atoms, forming radioactive 41Ar .
- 41Ar ionizes due to recoil from the neutron capture.
- The ion is attracted to dust and water particles, keeping it close to the ground after formation.
- Because of this, the effects of 41Ar are most strongly felt upwards of 20 km from its point of formation, rather than immediately next to it.
- The measurable effect is an increase in the male-female sex ratio at birth, because the X chromosome has more DNA than the Y chromosome and is more susceptible to damage.
Got that? I lost 5 IQ points just from reading the crap required to write that summary, so I'm not going to repeat it. Oh, the "researchers" conveniently left out the mechanism by which 41
Ar singles out the sex chromosomes for damage, rather than causing mutations and consequent birth defects all over the genome. It's just one of the ways that 41
Ar is evil, I guess.
Back in reality, things are just a little bit different.
Argon is only a trace constituent of air. Nitrogen is 78% of air by volume, while all isotopes of argon are only 0.93%. Further, each molecule of nitrogen has two atoms while argon has but one. Last, the thermal neutron capture cross-section of nitrogen is 1.91 barns, while argon's is only 0.675 barns
. The upshot is that a free neutron in air is about 470 times as likely to be soaked up by a nitrogen atom (forming
stable 15N 14
C by the (n,p) reaction) than by 40
Ar. My understanding is that even that's not terribly likely, and the most common fate of neutrons in air is beta-decay to hydrogen (half-life ~11 minutes).
But let's follow this to the end. 40
Ar plus a free neutron have a total mass of 40.9710480385 AMU. 41
Ar masses 40.9645006 AMU, for a difference of 0.0065474385 AMU or on the order of 6 MeV. This will be released as a gamma ray. This is certainly enough to ionize an atom... but is it likely to stay
that way? The ionization energy of argon is 15.7 electron-volts (eV). The ionization energies of both nitrogen and oxygen are less than that, so at the first collision with an oxygen or nitrogen molecule the newly-formed 41
ion is going to steal an electron and not be an ion any more. That will take on the order of picoseconds.
Last is the issue of location of the decay. The typical human contains enough potassium that the beta decay of 40
K occurs around 4000 times per second; against this background of beta decays, you'd have to have a huge effect from 41
Ar to measure something. But even if an atom of 41
Ar was able to stay ionized, attach to a dust particle or water droplet, and stick around near a human, what is the likelihood that it could be ingested and migrate to the gonads before it decayed? Roughly zero.
The funniest thing about this 41
Ar "theory" is that there are actually people who take it seriously. So who's pushing this nonsense? There are two basic possibilities here, not necessarily mutually exclusive: either they are objectively deluded (crazy), or they want you to be. The latter want to panic you into following their agenda, which you wouldn't do by pursuing your own interests. And that, my friends, is evil.

Someone on The Energy Collective
suggested that 24/7/365 facilities like data centers could run on "renewable energy" (meaning unreliable wind and solar) by taking the first pick of power from a wind farm or other facility and letting others take the surplus. Specifically, he said this:
The wind farm that HP is drawing from is 300 MW. If they get first dibs on generation,it's not out of the question that 95 percent of the time it will generate more than 112 MW which would be a 37 percent CF.
Is that true? I decided to find out.
Here's a plot of Texas wind generation over March of 2014, courtesy EIA:
I cut this down to a 143-by-489 area (69927 px²) of just the plot itself trimmed down to the production maximum, and used Gimp's histogram function to measure the red area. It came to 32026 red pixels. If we assume that the production peak was 100% of nameplate (unlikely, but it's favorable to the case) that's a capacity factor of 45.8% for the month.
45.8% of the 143 pixel height is 65.5 pixels. Cutting the graph down to 65 pixels from the baseline yields this:
The curve never quite goes to zero, but it gets close to it several times; it stays very low for an entire day. Even the wind across the entire state of Texas, cut down to its capacity factor for the windy month of March, is not reliable enough to keep data centers running; the net capacity factor for the entire state of Texas
is just 73.9%, far less than the 95% assertion of "wind smith". The infrastructure of an information economy needs reliability more like 99.99%.
But what's left over? Here's what that curve looks like:
In the windy state of Texas, in March 2014, the "leftovers" from preferred loads taking everything up to 45.8% of the peak has a capacity factor of just 22.1%. It's a very spiky curve that has gaps lasting days when there is little or no power available. What sort of business or process could anyone operate using power that was so unreliable? I can't think of one. Maybe you could dump this power to heaters or some other extremely cheap load, but what you'd do with the heat I'm not sure. At one point I had the idea of using surplus electricity to heat crushed concrete, with the goal of dehydrating the cement and converting it back to separate streams of cement, sand and aggregate for recycling into new concrete. I don't know if this is chemically possible (does hot cement react with sand or otherwise become inseparable and unusable?), but at 22.1% capacity factor the kilns and sifters and whatnot would have to be very cheap to make this a workable proposition and you'd have to get the power for close to nothing.
"Renewables" fanatics (maybe I should start calling them "windbags") like to say that the wind is always blowing somewhere. At least for Texas in the month of March 2014, that much was true. However, there were many periods even in that blustery month where it was certainly not blowing hard enough to keep essential 24/7 things running. When it comes down to e.g. pumping stations filling up and backing raw sewage into homes and buildings because the unreliables are not there that day, even the most fanatic Green is likely to burn fossil fuel instead.
The unreliable sources of energy are simply not going to replace fossil fuels. They can't; their characteristics make it an engineering impossibility. This is why Greens need to drop their contrived objections to those sources of energy which actually can.
After reading "Ender's Game" and so many of his other works, I thought that it was mighty hard to go wrong with Orson Scott Card.
I can now say that it is a sinking feeling to find out just how wrong I was. At least, when he affixes his name to something as a co-author.
I read "Earth Unaware", and shouldn't have bothered finishing it. Is OSC phoning it in, or what? Based on what's in the book, I'm assuming that his contribution was his name and some of the characters which show up in later novels. His co-author Aaron Johnson has no concept whatsoever of orbital mechanics, radio propagation, or even basic physics like elementary particles. The least one can do if one can't remember the difference between gamma rays and cosmic rays is look it up
, and it's excruciatingly obvious that he didn't bother.
There are scientific howlers throughout the off-earth parts of the book. An alien ship moving at a large fraction of lightspeed... takes weeks to travel inside the orbit of Jupiter, and human ships of far inferior capability nevertheless match velocities with it! This ship generates radio noise of sufficient intensity to block non-laser communications... yet humanity appears to have forgotten how to make and use radio telescopes, because it hasn't been detected, pinpointed and intensively studied because of those very emissions! Dust particles and gas in the Kuiper belt are a hazard to space-suited persons outside ships moving at speed... ignoring the fact that the solar wind sweeps dust into interstellar space, and the solar wind itself is moving as fast or faster than the velocities given in the book! Oh, best of all: the simple expedient of orienting the ship so that the hull intercepts anything from the direction of motion never occurs to the author.
If Card cared for his reputation, he'd ask Tor to remove his name from this book. If Tor had any integrity, they'd stop selling it as SCIENCE fiction.
TL;DR: No. At least, not chemically.
In a discussion about residential radon in which I linked this NIH study
which found that lung cancer decreases with rising residential radon levels, someone asserted that you could die by radon poisoning. I challenged that, saying that I'd calculate just what would happen if you had even 0.1 vol% radon in air. Then someone else said that people had died by radon suffocation in Appalachia, so I went and did it.
Stipulate that 0.1% by volume in air is two orders of magnitude below anything presenting an asphyxiation hazard. Radon has a density of 9.73 grams/liter, so 0.1% by volume would be 9.73 mg per liter or 43.8 μmol/liter.
The half-life of Rn-222 (the only isotope which lasts long enough to get out of soil and hang around much) is 3.824 days. This means that there's 1/e of it in 5.52 days, or 2.1e-6 (1/(86400*5.52)) of it decaying per second. For 43.8 μmol, this is 9.2e-11 mol/sec decaying or 55 TBq (terabequerels).
The decay energy of Rn-222 is 5.5 MeV, so that 4.38 μmol has a total power output of 3.04e20 eV/sec. An electron-volt is 1.602e-19 J, so that works out to 48.7 watts per liter of air. The air in a room 3mx3mx2.5m high (22500 liters), spiked with 43.8 μmol/liter Rn-222, would release about 1.1 megawatts of heat.
Anything and anyone in such a room would catch fire in seconds. There would be no time to suffocate.
Do I need to mention that if such high concentrations of radon were found in nature, people would pump it into tanks and use it to boil water? It would be one of the most fantastic sources of free energy imaginable.
Pursuant to a dissussion on Rod Adams' blog, I'm likely going to be digging into ultrasupercritical steam cycles today. This made me realize that most people who do this are either paid money for the effort, or are studying so they can be paid money for it.
Should I be taking commissions for analytical posts? Something like GoFundMe? I can use the money.
Are there any gaps in the public-domain analysis out there that maybe I could fill?
Bend my (virtual) ear.
I picked up a link to an article on the Monticello nuclear power plant and the alleged un-economic nature of the cost overruns of its recent power uprate
, and went to try to add this to the discussion:
Let's have a look at the facts, shall we?
The Monticello nuclear plant is rated at 671 megawatts net. The plant can be expected to average more than 90% of this figure (more than 600 MW), and since refueling outages are scheduled for seasons of low demand its useful capacity factor is close to 100% during the peaks of summer and winter. All of that generation is free of air emissions of any kind, especially carbon.
It may be true that...
it’s enough money to install over 400 megawatts of new wind power.
But 400 nameplate megawatts of wind turbines, even at a generous capacity factor of 40%, is just 160 megawatts average (barely more than 1/4 of Monticello). Neither does that figure include the cost of new transmission lines and other upgrades which are required by the new wind even if they're not billed to it; those can cost as much as the wind farms themselves. Worst, wind farms go dead during winter and summer high-pressure systems which bring heat waves and cold snaps.
Ignoring these things won't make them go away. Tragically, the advocates of "renewables" appear to be sticking their fingers in their ears to avoid hearing the words of Robert F. Kennedy, Jr: "the plants that we're building, the wind plants and the solar plants, are gas plants". Replacing Monticello with wind plus gas means about 2 million extra tons of CO2 emissions per year, about 30 million tons by 2030. At a social cost of perhaps $50 per ton, that is $1.5 billion to go "renewable".
Please wake up.
However, immediately upon creating an account to enter this, I was faced with this screen:
Apparently, the drawbridge has been pre-emptively raised against any attempt of the truth to invade their little castle of delusion.
Leveraging existing assets is one of our best prospects for cleaning up the air and cutting petroleum consumption. An under-appreciated possibility is using conventional hybrids, even retrofitting existing ones, to substitute a bit of grid power for petroleum fuel.
In an article on advanced lead-carbon batteries for mild hybrids at GCC
, there are these notable phrases:
The state-of-charge (SoC) of current lead-carbon batteries is typically maintained at between 30 and 50%.... Advanced lead-carbon batteries for vehicles currently under development will be capable of operating in the 30 to 70% SoC range at 12.5kW.
That's operation. What about off-line? Lead-acid likes to be held at 100% SOC, and I doubt that lead-carbon suffers at all from it. NiMH batteries also appear to prefer to be held at 100% SOC and cycled only shallowly
. Neither could accept regenerative braking power when full, but when the vehicle is starting and driving shortly after start there is no braking energy to recover.
The GCC article continues:
Future battery developments will most likely combine advanced lead-carbon electrochemistry with ... substantially reducing the size of a 1 kWh battery required for mild electrification of the powertrain.
The hybrids and mild hybrids of tomorrow will have on the order of 1 kWh (above) to 1.3 kWh (base Prius) of battery, and operate it in a SOC range centered between 40% and 50%. But if the battery was charged to 100% SOC off-line, there would be between 500 and 700 Wh of extra energy to move the car (or for other functions, like instant high-power defrost). This is enough for perhaps 2 miles of petroleum-free driving, perhaps more if the first stretch after starting is creeping in traffic for an extended distance.
How much fuel could this save? Approximately 930,000 hybrids (not plug-ins or BEVs) were sold in the USA in 2012-3. If we assume 10 battery top-offs per week 52 weeks a year, 2 miles range per top-off and 40 MPG consumption avoided, the 2012-3 fleet would avoid about 1 gallon consumption per vehicle per week, 52 gallons/vehicle/year, 48 million gallons/year for the fleet. The total for the hybrid fleet going back to the oldest Priuses on the road would be multiples of this, perhaps a good fraction of a percent of total US gasoline consumption.
What could this do for the grid? 1.2 kWh/day 5 days a week isn't much, but if you can draw it on demand it might be worth something. The J1772 Level 1 spec is 120 VAC @ 12 A, or 1440 watts. 930,000 vehicles @ 1.44 kW/vehicle is 1.34 GW of potential demand. It would take only about 25 minutes to put 600 Wh into a battery at that pace, but 25 minutes of demand equal to a large nuclear plant available twice a day (perhaps 3x, if vehicles are plugged in during after-work errands) might be very useful to ISOs for down-regulation of the grid.
This is a small possibility, not a big possibility. But there is a big push for mild hybrids (perhaps multiples of the number of conventional hybrids), and a lot of littles make a lot.
Do you recall the PSR hysteria about the unloading of SNF from Fukushima Dai'ichi Unit 4, and how it was a deadly threat to all life on earth, the "most dangerous moment since the Cuban Missile Crisis
"? (Older post
, later update
Well, I must announce that Wasserman's worst nightmare must have come true. TEPCO announced that all spent fuel has been removed from the Unit 4 fuel pool
, leaving only 180 unused fuel elements (unused fuel is safe to handle by hand). Since we were told that it was impossible to handle this job safely yet we heard nothing of this, it stands to reason that it killed us all in our sleep, and we are in some dreary Hadean afterlife in which we continue to go through the motions of existence without any knowledge of what happened to us.
be some dreadful thing like this, because Harvey Wasserman, PSR, UCS, etc. could not possibly have been wrong. Could they?

Mostly, they seem to be lying to themselves. However, that they repeat falsehoods as fact cannot be disputed and suggests that the entire Green philosophy is one enormous delusion.
A little while ago, I was flabbergasted by one Bob Wallace, moderator, censor and ban-hammer wielder of Cleantechnica.com [1
], who flatly stated that nuclear is not dispatchable. Not just once to me, but many times going back years
Digging a little deeper I found that this meme-virus had some fairly old (as the web goes) roots. The Wikipedia article on dispatchability still says as of 2014-10-08 that nuclear power is not dispatchable
. This claim goes back to the very first version of the page in 2006
In my research I found a grid operator definition of dispatchable meaning the generator having filed an energy supply curve with the ISO, but I'm unable to find it again. But the EIA rides to the rescue
. Under "Dispatchable Technologies", it lists:
- Conventional Coal
- Advanced Coal with CCS
AND (last but not least)
- Advanced Nuclear
(there being no un-advanced nuclear entering the market in 2018)
Bob Wallace will probably back-pedal and claim that today's nuclear isn't advanced and isn't dispatchable. But for the last 30 years, France has been load-following with its fleet of 1980's-vintage PWRs. How can you follow load, if you can't dispatch generation on demand to follow it? Ridiculous.
I expect to see more such howlers from Bob Wallace and his ilk. AAMOF, I would wager that he'd even repeat his "nuclear is not dispatchable" claim after being referred to the EIA page. In other words, what Bob Wallace says can only be taken as a recitation of Green dogma. One cannot expect any evidence of independent thought or any acceptance of facts from outside his echo chamber.
A lot of what Bob Wallace says (along with the rest of orthodox Greens) is out-and-out lies. This is not to say that they are consciously lying. They may very well have accepted a delusional belief system structured to support the romantic Green vision, and can't pry themselves away from it. But that means that they have, for all intents and purposes, surrendered their ability to think. Without the ability to actually reason from facts, even uncomfortable facts, they are intellectual zombies: shambling along, eating the brains of those too slow to evade them and turning them into more like themselves.
And that, folks, is why so much discussion of our energy future is Sofa King Stew Pit.
He doesn't like it when you use the phrase "put you in my crosshairs
". There's a list of other things he doesn't like, none of which are noted prominently enough for the casual Cleantechnica commenter to have any idea what they are before being censored, banned or both for transgressing them.

If we are serious about greenhouse gas emissions then the only way forward is to realize we need 10x more energy even with the best energy efficiency technology employed globally. And then plan fossil fuel consumption accordingly. But then we have 10x the energy need while we need 10x less ghg emissions long term! I think we will find that in such a future world, we may only use (10% of 10% =) 1% fossil fuels to stay within long term acceptable ghg emissions limits. It is such a drastic reduction that we really need to think about zero carbon economies. CCS with 90% efficiency will not be good enough. It will need to be 99% efficient. Solar and wind grids with 30% natural gas backup will not be acceptable. They will have to be 98% solar and wind and 2% natural gas.
Once you look at those futures it is clear that wind and solar and CCS can’t cut the mustard. They are unacceptable greenhouse gas emitters…
Hence in my opinion such technologies are part of the global energy problem (except for niche uses), not part of the solution.
With sufficiently cheap energy, pollution would become a thing of the past; at current levels of energy usage, this is impractical. Most of our species is still locked in the subsistence-agriculture trap, and simply extending the First World system of coal- and petroleum-fueled industrialism to them would probably destroy the planet.
This knowledge is the specter at the feast of progress, now that Western civilization is overcoming the self-inflicted wound of 1914 and its consequences. The so-called "soft" path is nothing more than a return to the animalistic misery of pre-industrial times; sunlight is simply too diffuse to maintain even the present level of consumption. Hard, concentrated energy is the essential prerequisite for an economy like ours; conservation and increased efficiency merely delay the problem without solving it. Restricting growth means a boot in the face of the world's have-nots; a tiny island of comfort on a swelling mound of resentful pain; eventually it means impovershing everyone.
