This has probably been discussed before, but what is the deal with much of the left's aversion to nuclear power? Why do so many leftists oppose it? I understand that it occasionally poses an environmental risk, but considering that fossil fuels have been discovered to be environmentally dangerous as well, isn't nuclear power a good alternative? Or do people feel that nuclear fission requires too much of an authoritarian structure to operat? I'm confused :bored:.

They do? The most vocal anti-nuclear energy folk tend to be greens, and greens ain't red. I haven't heard very much about nuclear energy from 'The Left', and they little I have heard tends to be moderately in favour of it. I'm not qualified to talk about any of this, though.

The problem with it is that the waste lasts "forever." Civilization could rise and fall many times, and that stuff will still be radioactive poison.

Surely technology could develop in order to take care of that, couldn't it?

I mean, it only isn't solved because it isn't profitable I suppose, or else it would be.

I've seen a lot of Greens change their mind (favourably) towards Nuclear Power in the past few years though... even if they do still advocate Car Bans in major cities :rolleyes:

Nuclear power is the only serious means of cleaner energy that does not require us to put a windmill in every garden and solar panels on every roof.
(yeah i am exaggerating but you get the point)

Also nuclear power provides us with essential medical isotopes something we should never abandon because of eco-fantasy's.

With modern technology nuclear power is safer then during the chernobyl days and the waste can be safely stored until we find a way to dispose of it permanently.

There are people on the left who don't like nuclear weapons, and by using nuclear power to generate electricity it means that the materials used in both are easier to get hold of (I think).
Perhaps the waste products could be used somehow, but you'd have to find a pretty good use for them that didn't go on to generate more toxic waste. (And currently, it would have to be a profitable use.) I'm not sure what the waste products decay into, or whether they can be used for anything at present though.
Edit: Nuclear power is fairly safe (toxic waste aside) if it's maintained properly, so the chances of environmental disaster are probably not that high.

Vitrification

http://upload.wikimedia.org/wikipedia/commons/thumb/f/fb/Vitrification1.jpg/220px-Vitrification1.jpg (http://en.wikipedia.org/wiki/File:Vitrification1.jpg) http://bits.wikimedia.org/skins-1.5/common/images/magnify-clip.png (http://en.wikipedia.org/wiki/File:Vitrification1.jpg)
A vitrification experiment for the study of nuclear waste disposal


Long-term storage of radioactive waste requires the stabilization of the waste into a form which will neither react nor degrade for extended periods of time. One way to do this is through vitrification (http://en.wikipedia.org/wiki/Radioactive_waste#Vitrification).[22] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-21) Currently at Sellafield (http://en.wikipedia.org/wiki/Sellafield) the high-level waste (PUREX (http://en.wikipedia.org/wiki/PUREX) first cycle raffinate (http://en.wikipedia.org/wiki/Raffinate)) is mixed with sugar (http://en.wikipedia.org/wiki/Sugar) and then calcined. Calcination (http://en.wikipedia.org/wiki/Calcination) involves passing the waste through a heated, rotating tube. The purposes of calcination are to evaporate the water from the waste, and de-nitrate the fission products to assist the stability of the glass produced.[23] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-council-22)
The 'calcine' generated is fed continuously into an induction heated furnace with fragmented glass (http://en.wikipedia.org/wiki/Glass)[24] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-23). The resulting glass is a new substance in which the waste products are bonded into the glass matrix when it solidifies. This product, as a melt, is poured into stainless steel (http://en.wikipedia.org/wiki/Stainless_steel) cylindrical containers ("cylinders") in a batch process. When cooled, the fluid solidifies ("vitrifies") into the glass. Such glass, after being formed, is highly resistant to water. [25] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-24)
After filling a cylinder, a seal is welded (http://en.wikipedia.org/wiki/Weld) onto the cylinder. The cylinder is then washed. After being inspected for external contamination, the steel cylinder is stored, usually in an underground repository. In this form, the waste products are expected to be immobilized for a long period of time (many thousands of years).[26] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-25)
The glass inside a cylinder is usually a black glossy substance. All this work (in the United Kingdom) is done using hot cell (http://en.wikipedia.org/wiki/Hot_cell) systems. The sugar is added to control the ruthenium (http://en.wikipedia.org/wiki/Ruthenium) chemistry and to stop the formation of the volatile RuO4 (http://en.wikipedia.org/wiki/Ruthenium_tetroxide) containing radio ruthenium (http://en.wikipedia.org/wiki/Ru-106). In the west, the glass is normally a borosilicate glass (http://en.wikipedia.org/wiki/Borosilicate_glass) (similar to Pyrex (http://en.wikipedia.org/wiki/Pyrex)), while in the former Soviet (http://en.wikipedia.org/wiki/Soviet) bloc it is normal to use a phosphate glass (http://en.wikipedia.org/wiki/Phosphate_glass). The amount of fission products in the glass must be limited because some (palladium (http://en.wikipedia.org/wiki/Palladium), the other Pt group metals, and tellurium (http://en.wikipedia.org/wiki/Tellurium)) tend to form metallic phases which separate from the glass. Bulk vitrification uses electrodes to melt soil and wastes, which are then buried underground.[27] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-Waste-26) In Germany a vitrification plant is in use; this is treating the waste from a small demonstration reprocessing plant which has since been closed down.[23] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-council-22)[28] (http://en.wikipedia.org/wiki/Radioactive_waste#cite_note-27)

There's more power in the oceans than we'll ever need, and if we upgrade the grid from copper to graphene, we'll have four times more power instantly (right now 75% of all electricity is lost as heat in power lines).

No need for nukes.

Nuclear power would be quite usefull for space exploration, and has a matter of fact its already used for space exploration.

Satellite and exploration shuttles, they are mostly power by nuclear battery.

i dont think we should be narrow minded about technology, Multiple option is i think better.

By the time we finally have socialism fusion power is most likely going to be the better choice. The ITER reactor is under construction and while it's just a test-reactor, it's the biggest one so far. One or two generations after ITER we'll see reactors which are going to produce more energy than is needed to keep them running (due to magnetic constraints and high temperature at which they operate). One or two generations after that we'll be able to fuse He3 with itself, which is considered to be the ideal type of fusion.

I'm very much against many fission reactors which were designed to create weapons grade plutionium or uranium. These reactors are inherently unsafe (Chernobyl was one such type of reactor).

Another problem is that fission energy is not CO2 free, given the vast energy requirements needed to mine the needed uranium (although it is not as high overall as directly burning fossil fuels). Massive amounts of water is also used at this process and of course we end up with large plots of barren landscape at the end.

A third issue is that with our currently known uranium stocks (most reactors run on uranium 235), with our current technology level and with our current rate of using these fuels, we'll be able to hold it out for about another 60 years before the stocks run out. Massively switching to fission energy is not an option.

Theoretically it is possible to simply reuse radioactive waste, in socalled breeder reactors, but the technological development has been on a standstill for decades. Kalkar, a breeder reactor in Germany built in 1985, was never used. Another issue is that much of the radioactive waste is molten into glass and therefore cannot be reused by current techniques (if at all possible).

In short: I'd put my money on solar cells and fuel cells for now and on fusion for the future.

No, I definitely think there is such a thing as bad technology. Anything designed for the purpose of killing human beings is bad as far as I'm concerned.

As far as space is concerned, I think nuke power is fine. As long as it isn't falling back to Earth (or any extra-terrestrial colonies we establish in the future) fine.

On Earth, though, we should end its use.

then again, most technologies who where created to kill humans have a dual function, even the most horrific things designed to kill human being have been or could have been used for a good purpose.

most of the stuff used in the gas chamber where taken from good technology (decontamination room, water purification pump etc etc) the poisonous gas used was originaly designed to kill lice.

rocket, who where created to strike armaguedon all over the hearth put the first man and satellite in the space.

so no, bad technology dosnt exist, only bad purpose of it.

and that large amount of toxic waste can be re-used to make battery, and progress have been made to limit and eliminate the toxicity of those items.

may i remind you that even solar energy generate a lot of dangerous waste, do you really think those solar panel can be built without generating some kind of toxic fallout?



it is extremely expensive and it is not necessary.

expensive is not an excuse, because expensive is a virtual limitation of capitalism.

look, you need electricity, and not all the places in the world have the possibility to have access to a dam, and solar power is not yet powerful enough to meet the current need in electricity.

so far you have coal, oil, nuclear energy, geothermal electricity and yet, the only one that dosnt reject matter in the atmosphere and and that is avaliable to all is nuclear power.

yea, nuclear waste are nasty, but relatively easy to contain if you are careful enough.

now, tell me how much people have been deeply affected by nuclear energy vs the number of people affected by lets say, oil?

you got tchernobyl, three mile island, and that was beccause nuclear energy was begining to be used.

for the oil, lets see, you got exxon valdes, many many other natural disaster that destroyed ton of wildlife, the indirect effect on the ozone layer, acid rain, etc etc etc.

when carefuly recycled and stored, nuclear waste are innofensive.

if you got a blueprint of cold fusion reactor in your garage, please feel free to distribute it over the net, and i would gladly accept the fact that nuclear energy is obsolete.

Until then, we shall use nuclear energy.

Quoting wikipedia article on vitrification:


Long-term storage of radioactive waste requires the stabilization of the waste into a form which will neither react nor degrade for extended periods of time.

To require that the container will not degrade chemically is not nearly sufficient, in my opinion. I say: long-term storage of radioactive waste requires zero probability that one of these containers will be fractured by an earthquake, and even larger tectonic events, such as collisions of contenents and the splitting of continents, during a period of five billion years into the future. This cannot be guaranteed, and, to me, that settles the issue. Nuclear fission should not be permitted on this planet.

One or two generations after that we'll be able to fuse He3 with itself, which is considered to be the ideal type of fusion.

Fusion is fantastic, and could provide near-infinite power with very little environmental impacts. However, making it actually work is a ***** of a thing. Even if ITER is a marvelous success, there's still a long way to go. I love the possibilities of fusion power, who wouldn't? However, I wouldn't count on it anytime soon.



Theoretically it is possible to simply reuse radioactive waste, in socalled breeder reactors, but the technological development has been on a standstill for decades. Kalkar, a breeder reactor in Germany built in 1985, was never used.

Breeder reactors have been problematic. Moreover, they substantially increase the risk of proliferation.


In short: I'd put my money on solar cells and fuel cells for now and on fusion for the future.

If we could capture and transmit one ten-thousandth of the sunlight that hits the earth every day, we could power the whole planet. However, again, the trick is capturing it, and not having the power bleed out through the transmission.

Don't be fucking ridiculous. You don't demand the same absurd levels of safety from any other technology (nothing is 100% safe!), and there is no sane reason to demand the same of nuclear technology.

In terms of radiation, the nastiest, high-intensity stuff lasts briefly enough that it can be temporarily stored somewhere to "cool off" before being placed in long-term storage. Once that is done, you can then vitrify the waste, ensuring that if the containers were to break, it would not contaminate the local water table, thanks to glassy substances being non-porous.

Of course, this waste disposal should only happen at the end of a long reprocessing chain, after we've wrung out as much energy as we can from the fuel. I'm not overly concerned about proliferation, so with regards to breeder reactors I say full steam ahead.

The problem with renewable energy sources is that they are very diffuse compared to nuclear - and while diffuse energy may be good enough for domestic use, it's no good for energy-intensive industrial applications. To get the levels and concentrations of energy that such uses require, we would need to build large powerplants of the kind that most renewables fans (so it seems) are against.

I find that incredibly hard to believe. Cyanide kills because it effectively stops cellular respiration by binding somewhere along the electron transport chain. Cellular respiration is very basic, and common to (at least) all animals and plants. Why would it be different for lice? Does it have to do with the manner in which they intake the cyanide?

from wiki:
idespread 'biological' application of hydrocyanic acid was initially limited to the fumigation (http://en.wikipedia.org/wiki/Fumigation) of valuable tree crops, namely of citrus fruit (http://en.wikipedia.org/wiki/Citrus_fruit), spreading 1887 from California (http://en.wikipedia.org/wiki/California)[4] (http://en.wikipedia.org/wiki/Zyclon-B#cite_note-3) to Spain (http://en.wikipedia.org/wiki/Spain) and other countries using liquid prussic acid or calcium cyanide (http://en.wikipedia.org/w/index.php?title=Calcium_cyanide&action=edit&redlink=1) or sodium cyanide (http://en.wikipedia.org/wiki/Sodium_cyanide) preparations. During World War I (http://en.wikipedia.org/wiki/World_War_I) other HCN-based pest control applications were developed, and soon fumigation of ships, stores, factories, and even residential buildings with hydrocyanic acid gas became a popular method to combat insect (http://en.wikipedia.org/wiki/Insect) and rodent (http://en.wikipedia.org/wiki/Rodent) pests in many countries.[5] (http://en.wikipedia.org/wiki/Zyclon-B#cite_note-4) Thousands of ships, cereal mills and other food processing factories were fumigated with hydrocyanic acid gas until the mid 1930s in Germany alone

Insects and mammals are different critters. What affects us and them is sometimes surprisingly different. Holocaust deniers use this to try and confuse people about the gas chambers, noting that the evidence shows that the level of gas present in the gas chambers (shown through concentrations of Prussic Blue in chamber walls) isn't sufficient even to kill lice, so how could it possibly kill humans. Seems reasonable on the face, until you find out that we're way more susceptible to cyanide than bugs are.

hydrogen? well, its all fine but you need energy to produce hydrogen, lot of it.

wind power and solar power couldnt meet the growing demand in electricity, those are good alternative, and sure they should be implanted more broadly, but overall its not efficient enough, even in great number to fill our growing demand.

and, until something stronger and better than fossil fuel is invented or discovered, the easy alternative around to meet the demand would be nuclear energy combined with various form of clean energy like wind and solar panel.

hey, unlike what you believe i am not saying that we should all have a nuclear central in our neigborhood, just that this is an option, like the other and it should not be brushed away just beccause its seem bad.

being against something like nuclear power just beccause it produce waste ,(that are more easier to deal than it was in the past btw)or sound extremely dangerous (thanks to greenpeace on this one) is liberal thinking, greenpeace threehugger talk.

Helium three can be "mined" from the moon. Hydrogen three, tritium, is "mined" from the oceans.

I wonder how heavy water tastes.
Naturally occurring tritium is extremely rare on Earth.

mining uranium require less ressources, time and less risky than sending shuttle on the moon to harvest a ressources that we have not yet determined the quantity avaliable.

Nuclear fission is unsafe, produces toxic waste, so it is not a sustainable solution to fossil fuels. The toxic waste is abundant and lasts for millenia.

The alternatives are solar and wind power, as well as geothermal and ocean wave/river current power. All these are safe and clean and should be developed as alternatives.

I really hope people here can stop hopping on the nuclear bandwagon, it's really annoying, but then again, some people seem to think it is somehow "green" because they have been duped by pro-nuclear propaganda.

There is nothing environmentally conscious about creating tons of radioactive deadly waste. Building thousands of facilities, which in the event of a meltdown, would devastate huge areas and render them uninhabitable.

Supposedly we are supposed to ignore the Chernobyl disaster, because this was supposedly more about Soviet incompetence than the danger of nuclear power. Thousands of people died from cancer because of the meltdown. The death toll would have been higher if it were a heavily populated area. Imagine if a city the size of New York City were located next to Chernobyl. The death toll and destruction would be apocalyptic.

All the more reason, really, to pump more resources into developing fusion technology.

Solar, wind, geothermal, and current power are all good, but a near-term development of the above would really dump these on the mud beside the road. Why bother with absorbing solar energy when you can directly replicate what stars do?

Several fusion reactions do produce radioactive waste actually, see this page (http://en.wikipedia.org/wiki/Helium-3#Fusion_reactions) for information. The most common type of radiation would be neutron radiation which is very difficult to handle because a neutron is an uncharged particle and therefore cannot be contained by a magnetic field for example.

But this type of radiation only causes the outer casing of the reactor to become radioactive. So every few years the casing has to be replaced and the old casing is stored as radioactive waste. Secondly this doesn't remain radioactive for many millenia, but for about 100 years.

What we want to achieve is a deuterium-helium3 reaction or helium-3 fusing with itself, which produces no neutron radiation.

Orbital Vector has a useful summary (http://orbitalvector.com/Power/Fusion/FUSION.htm) on the types of fusion and their pro's and cons.

As for meltdowns, they are impossible with fusion.

Nuclear fission is unsafe,

All industrial technology is "unsafe" in that they can cause serious injury and/or death if not properly utilised. This statement of yours does not add anything to the argument.


produces toxic waste,

Which can be recycled a number of times.


so it is not a sustainable solution to fossil fuels.

Is 5 billion years long enough for you? (http://nextbigfuture.com/2008/08/how-long-can-uranium-last-for-nuclear.html)


The toxic waste is abundant and lasts for millenia.

Actually, compared to the wastes that fossil fuel plants or the chemical industry produce on a yearly basis, waste is minimal.

I've already pointed out that the longest-living stuff isn't what we should worry about.


The alternatives are solar and wind power, as well as geothermal and ocean wave/river current power. All these are safe and clean and should be developed as alternatives.

While they should be used, they are not a panacea. Renewables are either too diffuse or too geographically limited to supply the totality of energy that civilisation needs.


I really hope people here can stop hopping on the nuclear bandwagon, it's really annoying, but then again, some people seem to think it is somehow "green" because they have been duped by pro-nuclear propaganda.

It's not propaganda, try reading a nuclear physics textbook.

Red herring. It's what happens to that waste which decides environmental consciousness.


Building thousands of facilities, which in the event of a meltdown, would devastate huge areas and render them uninhabitable. Supposedly we are supposed to ignore the Chernobyl disaster, because this was supposedly more about Soviet incompetence than the danger of nuclear power.

It was more than that. We can ignore the Chernobyl disaster as far as modern nuclear power plants are concerned, because they do not use the RBMK design.


Thousands of people died from cancer because of the meltdown. The death toll would have been higher if it were a heavily populated area. Imagine if a city the size of New York City were located next to Chernobyl. The death toll and destruction would be apocalyptic.

Actually, the consequences were slightly increased cancer rates, which are a drop in the bucket compared to the two biggest exposures to carcinogens one is likely to encounter, air pollution and tobacco smoke.

You're also working from a sample size of precisely one. It is quite simply dishonest of you to assume that the risks with modern reactors are the same as the much-criticised RBMK.

First of all let's not ignore feasibility and cost; mining He-3 from the moon and fusing it is for now SF.

He-3 fusion would be the ideal energy source for the future, but for now it's not a solution.

we can neutralize nuclear waste using x technology; no again; even if it were possible, if you'd do that you'd most likely lose the competitive advantage of nuclear fission; if we'll use nuclear energy in the future, then it will have to by dirty, otherwise there's no material incentive at all

I say let's use the best technology we can; with the least impact on our health and whose cost is not prohibitive; if fission is the only way to go, then be it; but as far as I can see, it's not; the present sustainable sources can cover all the energy needs for today and the foreseeable future; since nuclear fusion is not yet an option yet, the only reason I find it necessary is for a space civilization (there's no wind in space :D, other than solar wind of course)

sure its feasable to create an immense and gigantic wind farm, but it would require a certain degree of centralisation, forcing whole chunk of population to give up their original source of power, taking away ton of ressources to many folks who wouldnt necessary agree with that.

i say, let the people choose.

if the middle east want to run on nuclear power beccause they have the ressources and the expertise avaliable, let them choose, if north america want to build an immense solar farm to meet their energetic demand, let them choose.

for some people going nuclear would be more easy than going solar, and vice and versa.

That's a theoretical potential, which is not the same thing as a practical source of power. There still remains the issue of wind being a diffuse power source, which means you will need to build more wind turbines over a larger arean in order to get the same output as a single nuclear power plant.

We should work on it though I'm not aware of any large project that researches He-3 fusion today. Even if ITER would focus on aneutronic fusion it would still take decades until they get it right. Fusion of any kind is not a solution today to the energy problems.



That's a theoretical potential, which is not the same thing as a practical source of power.

Actually studies like this are made all the time; it's what tells cappies where to build wind turbines at a profit.

The potential takes into account only locations with mean annual wind speeds ≥ 6.9 m/s at 80 m.


There still remains the issue of wind being a diffuse power source, which means you will need to build more wind turbines over a larger arean in order to get the same output as a single nuclear power plant.

Buy all means, that's good to hear; instead of having huge power plants near water bodies whose malfunction could cause a blackout on a large area, a more decentralized approach is not only is more reliable, but it may as well be closer to consumers, thus reduce grid losses; the area it requires compared to a nuclear power plant is irrelevant; it can be seemingly integrated with other activities such as agriculture with little land usage; I haven't seen a nuclear power plant built in the middle of a farm yet :D


Reprocessing can significantly lower the demand for raw uranium.

And increase the cost of nuclear energy; reprocessing isn't cheap; that's why it's hardly used today, so that nuclear power can still be competitive.


What are you talking about? Not only does reprocessing reduce demand for raw uranium, it also reduces waste volume.

I was talking about those advocating using neutrons to reduce the amount of radioactive wastes. And yes, both reprocessing and other non implemented technologies created to reduce the amount of waste, also happen to increase the costs of nuclear energy, hopefully to obsolescence.


Two words: Energy density. Uranium (and Thorium) has it in spades; renewables do not.

Nuclear power plants can have multiple reactors, thus increasing reliability with each additional reactor. As for integration, waste heat from reactors can be used to provide hot water or desalination, and the neutron flux can be used to irradiate materials for various purposes.


And increase the cost of nuclear energy; reprocessing isn't cheap; that's why it's hardly used today, so that nuclear power can still be competitive.

Reprocessing is only expensive because hardly anyone outside France does it. The French have an extensive nuclear infrastructure, and the pay-off can be seen through the fact that they are a net exporter of energy.


I was talking about those advocating using neutrons to reduce the amount of radioactive wastes. And yes, both reprocessing and other non implemented technologies created to reduce the amount of waste, also happen to increase the costs of nuclear energy, hopefully to obsolescence.

That assumes that the cost of nuclear energy cannot be reduced, which I submit is not true.


That's a strawman argument; energy density is irrelevant; what matters is whether it can cover all energy needs and the cost associated with it (man power, externalities, health effects and others)

Energy density is actually very relevant if one has any interest at all in maintaining energy-intensive industries.

Nuclear does not need to cover "all" energy needs; if we are to learn one lesson from the past century, it is that it's foolish in the extreme to rely on a single type of energy source. For our own sake, energy sources must be diverse, and that in my mind includes nuclear.

Your original argument was that wind power requires too much land usage. It doesn't. Waste heat from concentrating solar power can accomplish similar tasks, without any of the problems nuclear power has.

Of course not; however the cost of extracting uranium will increase and the needs for safer nuclear plants will increase the cost further and phase out concepts such as molten sodium breeder reactors which could reduce the demand for uranium a lot.


Energy density is actually very relevant if one has any interest at all in maintaining energy-intensive industries.

Surely a chemical plant doesn't care whether the electricity it uses is generated by nuclear plants or wind turbines.

Energy sources should be diverse and there are many types of sustainable energy sources, such as geothermal, solar, wind, hydro and others.

Who says molten sodium reactors cannot be made safer? Also, thorium can be used as a nuclear fuel and is three times as abundant as uranium.


Surely a chemical plant doesn't care whether the electricity it uses is generated by nuclear plants or wind turbines.

Energy sources should be diverse and there are many types of sustainable energy sources, such as geothermal, solar, wind, hydro and others.

It's a question of distribution. Solar and wind are diffuse energy sources; there may be an awful lot of energy in the world's winds and sunlight, but it is all spread out and in the case of solar, limited to the daytime unless you want to invest in storage systems and extra plant to fill them. Hydro and geothermal are limited by local conditions such as suitable valleys or hot spots etc.

You need machines to concentrate the diffuse energy, and since machines are made of matter, it costs energy to turn into useful forms. A nuclear power plant is concentrated in a single area, which reduces transportation costs, especially if it is being built near an already existing efficient transportation system such as a railway. So even making the generous assumption that a renewable plant of equivalent mass to a nuclear plant can generate the same amount of energy (generous because nuclear reactions have a high energy density), nuclear is better if you want constant, large loads of energy. In fact, just the sort of loads that heavy industries require.

Whose preferred method? Extracting uranium from seawater today is as practical as mining helium from the moon. At least the latter could, in theory, provide nuclear energy without any radioactive materials in the entire production cycle, no possibilities for catastrophes and no health impact on any of the workers, a huge step ahead.


I did not say that the land could not be used for other purposes - the problem is that windmills are spread out over a large area, which results in increased use of materials.

Now that makes absolutely no sense.


CST still faces the problem having more specific locational demands than nuclear.

Who says molten sodium reactors cannot be made safer?

Remember the sodium+water reaction in high school chemistry labs? Sodium explodes on contact with water and molten sodium instantly catches on fire in air. I can only imagine how safe a water-molten sodium heat exchanger must be.:D

You need machines to concentrate the diffuse energy, and since machines are made of matter, it costs energy to turn into useful forms.

I'm not sure what you mean by concentrating wind power. Anyway, it takes energy to make nuclear power plants too. Unless you supply some statistics, this is irrelevant.

So even making the generous assumption that a renewable plant of equivalent mass to a nuclear plant can generate the same amount of energy (generous because nuclear reactions have a high energy density), nuclear is better if you want constant, large loads of energy. In fact, just the sort of loads that heavy industries require.

Fortunately, that's not the case. Wind and solar power, for instance, are complementary; solar power is at its peak during the summer and day; wind power during the winter and night; and of course, by connecting together power sources on large ares, using hydroelectricity or more novel concepts such as molten salt thermal storage, the production can easily be balanced with the demand.


I've been giving reasons why I think your position is wrong. If this annoys you, perhaps you should consider what the purpose of discussion forums are.
