Japan: "No cause for alarm"

The rods are in, the cooling is on, the reactors are in cold shutdown,
or heading there rapidly. Being irreparably damaged, which they likely
are at this point, doesn't make them any less cold or any less shut
down.

Most of the real problems seem to be with the spent fuel pools, which
are not reactors.

The press has been confusing the issue horribly because they make no
distinction between the reactor itself, the spent fuel pool, and the
building containing both. If someone dropped a cigarette in a
wastebasket it would be reported as a fire in the reactor.

One wonders if they manage their houses the same way.

Solar cells have been on an exponential curve of increasing installed

and around 10-30 years from now it will cost the same to reroof a house
with solar cells or ceramic shingles.

At that time the demand for fossil fuel will start dropping
significantly because peak load will be replaced by solar over a period
of about two decades. Nicely timed, too.


Storage is a different story. There will continue to be demand for base
load generation.

Which makes it a rich person solution.

This is one problem I have with many proposed "solutions" to various
problems--they are solutions that work for rich people, not for people
who struggle to pay the bills they have now.

[snipped screenfuls of stuff, including some about solar power]


Here in California, where there are spot shortages of electricity,
daytime air conditioning peaks are always blamed. If we can take care
of those peaks, and some other needs, by solar power rather than
building more fossil fuel plants, that seems good to me.

Waiting until we have a total solution is not my style. I like to see
the little bugs get worked out in smaller projects first.

When sustainable power/heating systems become standard building code,
they won't be just for the rich. 100 years ago or less the UK was still
building social housing for the low paid, with no indoor plumbing or
central heating. Today's new social housing and housing-to-let builds
have those plus double glazing, high insulation and car parking as
standard.

Before I've mentioned that coal fired plants release more radiation than
nuclear plants. I've wondered if the numbers include Chernobyl. It
turns out Scientific American just published an article about it that
does not answer the Chernobyl question. The issue is that there are
trace amounts of uranium in coal and those trace amounts get
concentrated int the ash.

That's good for CA, but in New England it would be night time heating
peaks.


By all means do pilot programs. But don't rush to full scale
implementation until you have the pilot program doing everything that
you need it to do.

On an individual basis no. They cannot say exactly when, where, or how
strong an individual earthquake will be. This is not about that. It is about
building for the worst case scenario. In terms of calculating the maximum
release a given fault can put out based on geological factors, geologists
have a pretty good handle on it. For example the southern california faults
max out somewhere around 7.5 IIRC (I could be off a bit) , but the northwest
Cascadia subduction zone maxes out around 9.0. It is similar to the faults
that caused the Indonesian tsunami, the Christchurch quake, and the Japanese
quake and tsunami. It is far more dangerous in terms of potential. Are you
saying that is silly and false? Please.

Geologists want nuclear power plants to take this into consideration when
determining reactor sites and designs and evaluating current safety.

So tell me how that is silly.

Don't be disengenuous. That's a schoolboy's argument. Actually, not an
argument at all, just a diversion.


See Granada. See thermal storage. Not perfect but if you can get 60 percent
of power in the day and 20 percent at night, do you not see that this is
massively better than burning fossil fuels for heat, electricity, and
transportation and living at the whim of foreign oil cartels? Seriously,
tell me why on earth that would not be better, even if it costs more.

You're not going to get sustainable energy without new costs. Do you want it
or not? And "I want it but don't want to pay for it" is the same as no.


Why? So you don't have to start somewhere unless it's perfect and in its
final form? Can you cite a technology which has been implemented that has
not improved in efficiency and/or cost over time?


Why don't you haul your happy ass over to Granada and tell them their system
doesn't work. Let us know how that works out for ya.

You don't want to believe, or won't say you believe the evidence about the
Spanish developments because I posted it. That much is obvious.

They are on pace for a much greater percentage in the near future.

So now you're the hysterical guy who doesn't believe science can make the
process efficient and says the sky will fall because we will cover the earth
with mirrors and silicon.

So Mister Engineer has no faith in science and engineering. I don't get it.


Waah. So you think the stuff you want won't raise raites? You think energy
costs are somehow magically going to remain stable? People had better get
used to paying more for energy, and in return, if politicians and vested
interests do not prevail, they might actually be able to hand a liveable
planet to their grandchildren.


Now that's just ignorant. You just want to argue if you're making statements
like that. And hey, maybe there are more important medical issues. Ya think?


And it is available.


OK, they use solar and other sustainable technologies. Is that better? A big
factory has a big roof. No reason not to have a big solar array. Long term,
it's more efficient that buying power from the grid and it's much better for
the planet.


It's already developed in basic form. The task is to make it inexpensive and
efficient to apply. For a guy who is supposedly educated in science and
engineering, you sound a lot more like the doomsday scenario people and
politicians whose agendas cause them to try to scare people away from
progress. Have you no confidence in technology?


The more it is developed and the more it is implemented, the less it will
cost. Why are you worried about money anyway? It's about sustainability and
efficiency, or at least, that's what you were saying about nuclear.


That's really a simple man's argument, who knows nothing of technology. You
should know better. And surely you can factor in costs over time rather than
today's build costs and consider less expensive more efficient equipment
which is destined to exist in the future unless a bunch of naysayers once
again stand in the way of science and progress.

Which makes it a solution for people who know how to read a curve on a
graph and make estimates. At some point the cost of solar cells on a
roof will equal the cost of ceramic shingles on a roof. Before that
point the majority of roofs will be solar. After that point all roofs
will be solar. All buildings need a new roof at some point.


Without extremely good storage solar will remain a peak load source and
thus remain a supplemental source. But when every new roof has them
it's going to help tremendously. I'll be alive when it happens.

Taxing the rich to pay for such things for the poor is not sustainable.
In case you haven't noticed, the UK has a big influx of the poor and
unproductive from other countries and a big exodus of the rich and
productive to countries that don't try to tax them into the poor house.

We have your assertion. Do you have a source for this?


That you are asserting that "we" know something that would be very
difficult to ascertain and when challenged refuse to support your
argument in any way whatsoever.

Reading a curve on a graph and making estimates doesn't help when you've
got 5000 bucks to pay for a new roof and solar panels cost 10000.

Ceramic shingles are themselves a rich person solution. You see very
few private residences other than McMansions with ceramic shingle roofs.
Around here the governor's palace doesn't have one.

The most common roof is asphalt composition shingle, which is a lot
cheaper to buy and to install than ceramic.


Not if it's going to take 30 years for them to get down to the price of
roofing that most people can't afford.

And around here if there's no storage it's unlikely that they'll
actually save anybody money--the peak load is at night and the utilities
will have to have enough generating capacity to provide it and they'll
have to pay for that capacity somehow.

Of course someone will enact a law that they have to buy back
electricity, which means that they'll just have to raise the rates to
cover the buyback.

Who said taxing the rich to pay for improvements in building methods?
Builders build houses to make a profit. Landlords let property to make a
profit.


For demographic reasons the UK NEEDS immigrants, they have a long
history of working hard, making a positive contribution to the country
and the economy (however poor they were on arrival).


The UK has more wealthy people than ever before.

What's seriously lacking is storage and transmission. The US strongly

we would have been totally on solar energy forty years ago. The
