This is OT, but does anyone out there have a good link for California Mello-Roos CFD maps (areas required to pay Mello-Roos taxes)?

Nuclear energy will, thank God, remain impractical because it only works now because it’s held up by cheap oil - what do you think powers all the trucks etc used to mine the fuel, transport it, etc.?

Nuclear energy will still be economical even if oil goes to $100. The energy output is much greater than the input required to mine/transport uranium. Do not forget than we can also have nuclear transport ships.

I dunno, I think there’s a lot of hidden/not-thought-about oil energy going into nuclear energy as it’s done now. kinda like how it’s not PC to think about how much oil goes into farming.

Perhaps, but a lot can be replaced by electricity, which can in turn be supplied by nuclear energy. For example, we can have hydrogen trucks/equipments mining and transporting uranium. Hydrogen can in turn be produced by nuclear/electricity.

I am not saying that not much oil goes to nuclear energy NOW. I am saying that it should not be too difficult to reduce oil-dependency in the nuclear energy.

Wind is also promising in many places. We just need to ignore "bird-lovers". :)

We should expect opposition whatever we do. Silencing/ignoring oppositions for the greater good will be the key in the future.

I personally don’t see that having any kind of energy crisis will affect most folks opinions on the risks associated with nuclear energy.

What risk? How many percent of population served by nuclear energy was ever killed in nuclear accidents? How many percent of population was ever killed in traffic accidents?

@Street Smarts,

Thanks for the flylady link --first time I've heard of it. Loved the Declutter page.

oh god infomercials on blogs how obnoxious.

@Richard Shmend, PhD,

As near as I could tell (in 5 minutes of browsing), the site was mostly free advice, but you may be right --maybe I haven't gotten to the "10 easy payments" part yet ;-).

RE: Nuclear cost effectiveness,

The arguments that the energy inputs override outputs is not supportable by the data. Even assuming that all inputs require oil (which isn't true), you are still talking about aggregate demand that comes no where close to even 1% of total energy demand. Agriculture is another story, but the energy input costs are still small in context.

The arguments about economic viability are more serious. Nuclear is weighted with regulations that make it more expensive than oil, gas or coal (but cheaper than solar, wind or exotic). I think many of the regulations are good, but you can't make the comparison between fossil and nuclear on these grounds because equivalent regulations are *not* applied to the fossil industry. I believe that if comparable safety regulations (implying comparable safety outcomes) were applied to coal (current generation), then coal would be some 3X as expensive per kW as nuclear. The sad fact is that the coal and crude lobbies are just more powerful and effective at keeping regs out of their industry, thus taxing nuclear and subsidizing fossil.

I have more faith in zero point energy.

You are assuming the Uranium resource curve is the same as the fossil resource curve. This is a false assumption. Uranium concentration discoveries are (a) still increasing and (b) dissimilar to fossil reserves. There is a finite amount of Uranium on Earth, but the economic supply formulae are different, and more favorable than fossil reserves (Uranium supply has a longer tail).

not really, you can make hydrogen from any power source…

Bio-diesel + cheap, simple, durable, *mechanical* engines.

It's so crazy that it just might work.

That is all,

Like oil, there’s been a lot of uranium, it’s even found in sea water. The other similarity is that like oil, only a portion is easy to get at. Peak Uranium is likely to come much sooner than Peak Oil relatively speaking but new discoveries may prolong that. Current sources of uranium are already being stressed and should the US, China and India along with others decide that nuclear is acceptable, then for all practical purposes, Peak Uranium will negate it as a realistic substitute for oil.

Datapoints please. Uranium can be extracted for under USD130 per kg, with over 4.4M metric tons of such concentrations currently in producing mines. The amount of actual Uranium extractable at this economy is more likely 2x-3x that amount due to the fact over half the world's productive mines have been closed over the past 30 years due to low Uranium prices on the world market. If reopened, and examined with current technology and technique, these mines would certainly be productive. Further, very little new prospecting has occurred in decades for new Uranium deposits. Quite bluntly, the Uranium supply arguments are void. If people have a political or ideological opposition to Nuclear power fine, but don't try to justify it with selective data. By the way, assuming a conversion to Nuclear electricity generation over a period of 100 years achieving 50% of global electricity production (this is overly conservative because it is too aggresive), known Uranium reserves would fuel 350-500 years of production. This is with current technology (which is really 25+ years old), excluding the more efficient French breeder designs which would stretch supply further.

Good. I bet we will have zero point energy long before Peak Uranium in 500 years. :)

One other point on the "50 years left" of Uranium argument. This is most likely a carefully selected snip from the Wiki on Nuclear power. The entire section reads:

At the present rate of use, there are 50 years left of low-cost known uranium reserves - however, given that the cost of fuel is a minor cost factor for fission power, more expensive lower-grade sources of uranium could be used in the future [16] [17]. Other ideas include extraction from seawater and granite[...]

Current light water reactors make relatively inefficient use of nuclear fuel, leading to energy waste. More efficient reactor designs or nuclear reprocessing [22] would reduce the amount of waste material generated and allow better use of the available resources.

Good. I bet we will have zero point energy long before Peak Uranium in 500 years.

You're not suggesting that the fundamental laws of thermodynamics are wrong are you? (You know, the "there's no free lunch" part.)

You’re not suggesting that the fundamental laws of thermodynamics are wrong are you? (You know, the “there’s no free lunch” part.)

The laws of thermodynamics are indeed very convincing. However, I somehow do not think that they are necessarily unbreakable. Laws of physics are quite a bit weaker than Laws of mathematics.

In his last book, he noted that the natural gas would be turned off to the power comp... ...idn’t know that 99.9% of home gas heating will not function without electricity.

I was a big Kunstler fan after "Geography of Nowhere", which really is a great analysis of the insanity of modern urbanism and architecture. Unfortunately, like me, he is only really capable of pointing out what is wrong. His next book, "Home from Nowhere" disappointed, the start of a rather rapid falloff.

He got really nutty during the Y2K panic, and really hasn't recovered.

Still, his aesthetic eye isn't awful, insofar as he recommends classicist principals. And his eyesore of the month is always good for a laugh.

Cheers,

Prat, thanks for delurking. :)

Thanks PS. I thought some of the French experimental designs were also FBR reactors. I know I read something about the plutonium consumption aspect of these being an economic consideration in the French energy policy: they'll agree to dispose of the rest of Europe's nuclear waste in exchange for free plutonium fuel.

While nuclear is great for electricity, permit me some skepticism on the viability of electric vehicles, the long-term prospects for hybrid vehicles and the workability of the hydrogen automobile.

We have a clean burning, renewable liquid fuel that runs in engines that are 20 to 50% more efficient that todays gassers and that are so simple that an idiot like me can understand them. These engines are repairable with basic tools, have over 100 years of engineering behind them, and last for well over 300K miles of heavy use. Further, the fuel can use our existing distribution infrastructure.

I know, I know. Diesel just doesn't seem futuristic enough, does it? Maybe if we dressed it up. Called it hydrozryixtonium or something.

@Peter,Harm,SQT,Jack,etc: sorry for the extended lurking. Work.

Cheers,

Praetorian,

I agree 100% on next-gen efficient Diesel. I think sometimes people get too hung up on "the sky is falling, buy a farm in Iowa" hysteria and they fail to realize that marginal improvements in efficiency through technologies like Diesel combustion engines will yield enormous economic benefits over a very long time horizon.

By the way, I grew up in rural farm-community Ohio; my wife lived her entire childhood on a family farm. For those who might be fancying some neoagrarian utopia, I suggest you actually try farm life for a while first. We didn't "ride our horses into town on market day". We "knocked the catalytic converters out of our old Fords so we could burn tractor fuel".

Iran will lead the way in meeting energy needs with fission reactors.

The technology to convert electric power into motion is actually pretty simple.

Quite right. And also quite efficient. However, consider todays hybrid engines. Simple? Easy to work on? Hrm.

As you point out, it's the storage that's the killer.

Not that biodiesel is without problems. Right now algae seems like the most promising source of it, and the theoretical yield is about 15,000 gallons per acre, per year. Probably only enough to supply 10 to 20 heavy drivers per year.

_shrug_

Still, in the long run, I'd bet on bioengineering and a simple combustion engine. Also, diesel landcruisers rock.

It used to be far cheaper to buy diesel, but now it’s even more expensive to buy per gallon than unleaded.

Yeah. Crazy, considering petro-diesel is much cheaper to make. In the Bay Area all diesel is lunatic expensive. You can get straight bio-diesel for $3.60 a gallon in Berkeley.

It really is sad that such a great engine technology got such a horrible reputation thanks to GM's engines back in the 70's. A bare-bones, small 4x4 with an inline CRD 4 cyl engine could get 30 mpg highway easily, with plenty of low-end torque.

Dammit.

What's the difference between a Realtorâ„¢ and an elephant?

And this is why it will take more than simply not buying their goo and vacating their soil to get the jihadists to back off, it will take stopping the reason for jihad, which means stopping the war against them by Israel, supported by us, that was started against them first.

Perhaps we could move the jews to Alaska...

Sad but true. I am reminded of the end of "Citizen Kane" where after Charlie Kane's death the camera pans across a vast ocean of consumer goods he has accumulated in his gigantic mansion and then falls upon some workers who are disposing of all of his crap by throwing it in the furnace! It all goes up in smoke and the man died lonely and alone, so look where the life-long quest for material shit got him!

DinOR, is your e-mail address working?

I guess I could have afforded a new boat but boats are only new the first year. It’s the payments that last forever!

Actually, it is new only right before you buy it. After then it would be used.

I remember my husband telling me that most people who retire early do so because they control their spending and save, not because they make tons of money.

If you ever played Cash Flow 101, you will notice that it is not easy to get out of a high-income/high-spending "rat race".

Where can someone go for reasonably priced furniture?

I envision a future with custom out-sourced furniture. One should be able to choose the fabrics/funishes on the internet and have it shipped directly from Mexico at 1/2 the price (or less).

Nuclear
Come on, it is not a safe option, Three Mile Island was my neighbor as a teenager, and nuclear is regressing folks. Even a tiny bit of fuel to dispose of will last thousands of years. -- newsfreak

With all due respect, this is a kneejerk reaction to a very serious problem that is many orders of magnitude more demanding than "feel good" solutions. There is no energy production technology yet feasible which doesn't cause safety and environmental stress, including photovoltaic solar and turbine wind. Of all the feasible, *large-scale* energy production technologies *currently available*, nuclear is by far the safest, both historically and trendwise. The current generation of FBRs are capable of reducing the "long-lived" waste by 95%.

Sorry for the direct response, but we have to approach energy policy rationally, not emotionally, if we're to have any hope of transitioning without causing a world war in the process.

This peak is Darwinian, evolve or DIE.

"Evolve" implies building upon past and existing technologies and techniques to ensure future viability. The must include *all* options, including nuclear, or you're not talking about "evolution" at all; only regressive reexploration.

Of all the feasible, *large-scale* energy production technologies *currently available*, nuclear is by far the safest, both historically and trendwise. The current generation of FBRs are capable of reducing the “long-lived” waste by 95%.

I agree. I am an absolute supporter of nuclear energy.

I also support wind energy. Offshore wind farms can provide much energy needs of some locations.

I thought the Jihadists hated the West because of the Crusades not cancer and staph.

They hated the west because of our apparent prosperity. Also, they need polarity for population control.

Any views on coal gasification?

"Any views on coal gasification?" --Jeffolie

Yes, I recently read a lot about it in "The End of Oil," by Paul Roberts. BTW, I highly recommend this book to anyone who is remotely enjoying this thread.

Anyway, coal gasification is costly, and expending the energy to remove the CO2 and sulpher and what not from the coal certainly decreases the effective energy yield of the coal. But given that the Earth has HUGE amounts of coal in the ground, and given that coal gasification technology will continue to increase the efficiency of the process, it is a good investment to make. So I do expect this "clean coal" technology to increase in popularity in the near future.

Wow, some great posts on alternative NRG --plus Prat & Escape from DC are back! Now all we need is for Jack to pop in agains.

newsfreak,

I have to second Randy H & Peter P on nuclear. Most people's perceptions are based on PAST technology --the old-fashioned light water Three-Mile style reactors. This design is inefficient and (as you mentioned) produces unacceptably large amounts of extremely dangerous and long-lived plutonium isotopes. The latest generations of Fast Breeder Reactors (FBRs --not be be confused with "F@cked Buyers) are much more efficient and --as Randy H pointed out-- can cut radioactive waste by up to 95%. Also, the waste that is produced has a much shorter half-life (hundreds vs. hundreds-of-thousands of years). The whole discussion on using thorium to consume plutonium was also intriguing --it might even be possible someday to dispose of the remaining 5%.

Even so, I don't see next-gen nuclear as a permanent solution, anymore than moving to other fossil stores will be (clean coal, tar sands, etc.). However, every form of "bridging" energy technology buys us more time and brings us closer to long-term sustainable energy. Whether that will ultimately take the form of bio-diesel, wind, wave, solar, fusion or a combination thereof, I don't know. But I wouldn't completely dismiss something as proven and viable as nuclear at this point.

And after X years, (where X=12 to 30), what will you do with the used photovoltaics?

Use them as the next trendy kitchen countertops? :)
