I hate to disappoint you but what the French are doing with their waste until now has been recycling fuel rods in La Hague and temporarily storing the stuff that cannot be recycled any more.
There is only a ONE breeder reactor, the Super Phoenix. The rest of the reactors are ordinary ones.
There's also something that makes me slightly less excited about breeder reactors than you seem to be: In an ordinary reactor water is used as a coolant (and in most designs works as a moderator as well). In breeder reactos like the Super Phoenix liquid sodium is used. May I point you to a near disaster whih occurred in the Fukui prefecture of Japan on December 8, 1995 when at an experimental fast breeder reactor, approximately two tons of liquid sodium leaked out of the system. The material was not radioactive and no explosion occurred however. It has been proposed that design flaw accompanied with metal fatigue led to the leak. This points to the problem with using liquid sodium as the coolant. Sodium is a very corrosive metal, making it hard to design a pipe to carry it to the heat exchanger.
If you have ever seen Sodium react with water you know what could have happened!
The difference is that the Archos Jukebox that Thinkgeek sells has a normal 2.5 inches laptop hard disk in it. Microdrives are much smaller, as small as any other compact flash card. Fitting a hard drive with 1GB in such as small space just seems absolutely amazing to me.
Check out this heise.de article (in German, sorry)!!! Somebody apparently programmed a little Linux tool that may be able to slow the spread of the worm down a little. The idea was first introduced in the incidents.org forum. May be worth a look.
Although I find the things you mention about coal and radioactivity highly interesting (thanks for the link!!!) I have to disagree with your claims about the use of breeder reactors in France. It is true that 70% (I found different figures in some articles, but this seems to be the figure that most agree on) of all power generated in France comes from nuclear reactors. However there is only ONE breeder reactor, the Super Phoenix. The rest of the reactors are ordinary ones.

how exactly do you define radioactive material? I mean U238 is radioactive and I'm sure the bricks out of which my house is built contain plenty of it. But U238 has a halflife of a few billion years...
So I highly doubt the figures you mention. If this were the case why not just release all the nuclear waste into some nearby river
If memory serves, the Chernobyl reactor used graphite as coolant, which started on fire when exposed to air. Very bad design.
I don't think so. As far as I remember the difference is that that most western reactors use water both as a coolant and to slow down neutrons (which increases the probability that a neutron will lead to the fission of another Uranium core). In Chernobyl water, too was used as the coolant but carbon was used to slow down the neutrons.
The problem now is that in a western reactor your chain reaction starts slowing down is the water evaporates because the water can no longer slow down the neutrons. In a Russian reactor the reaction rate would increase if water evaporated because the coolant would be gone, the graphite however would still slow down neutrons.
Your knowlege of the subject is breath-taking!!!
Natural Uranium mostly consists of U238 and only.7% (I think) U235 and U234. This share is then raised to about 3% so it can be used in reactors.
You will not find any nuclear reactor in which U235 turns into lead, because lead is the product of natural decay of uranium which has a halflife of several billion years as far as I remember. The process used in nuclear reactors is nuclear fission which produces much lighter atoms such as Xenon and Strontium.
I'm not sure if U235 is also used in bombs, the stuff primarily used is plutonium though!
Nnow to breeder reactors. They use a a core consisting of U235 and plutonium which is surrounded by U238 which bred to become fissionable. One of the main problems however is that this produces such an enormous amount of heat that water doesn't work as a coolant here so liquid sodium is used. At the end of your cooling circuit however you have to use water to get the whole thing back to normal temperature. Now liquid sodium is an enormously aggressive substance and if it should ever leak out of some pipe and come in contact with water...
Remember also that Bertelsmann holds a pretty big percentage of AOL Europe's shares, so there's business ties between AOL Time Warner and Bertelsmann already.
do people believe that earth is only 6000 years old, despite the massive amounts of evidence that suggests something else. Then they try to "prove" it using "science" and then use public schools to teach it to little kids so they don't go bad and become agnostics or even atheists.
And you think US companies dont engage in bribery themselves. I hate those double standards here in the US, while intervening in Kosovo, because of atrocities the US sold massive amounts of military equipment to Turkey...
I really hope all this was a joke, in case it is not, I have to say some things in response to it: Why does our current government not speak out about Europe's crimes against humanity? Of course European countries have committed horrible crimes. The difference is that children are being taught about them in school to learn from mistakes maken in the past. You won't hear a lot about the crimes against native Americans or Blacks here in the US... When you've got homosexuals running around everywhere, apparently unleashed, it's a problem. When you've got socialists scattered everywhere you look, it's a problem. What the hell is wrong with that. Hello, we live in a democratic system, both Europeans and Americans and as far as I know the US constitution doesn't prohibit being gay and if I interpret the First amendment which says "Congress shall make no law... abridging the freedom of speech" it is OK to be socialist, too. Their laughable adherence to the "metric" system is another offense. Yeah, I hate the metric system, too, it's so... complicated: 10 mm = 1 cm , 100 cm = 1m , 1000 m = 1 km. In comparison the American system seems so much easier: 12 in = 1 f , 3 f = 1 yd , 1760 yd = 1 mi When you've got church attendance declining and strict adherence to fundamental Christian principles nowhere to be found, it's no wonder that Europe is in such bad shape! This is precisely why America leads the world; we've got Christ leading us! Right, and English is God's language! Sorry I have to quote Marx, THE Communist, now: "Religion is the sign of the oppressed creature, th sentiment of a heartless world, and the soul of a soulless condition. It is the opium of the people." You're right about nothing good ever having come out of Europe. Right, it was not a European that invented the car, one of the leading rocket scientists that worked on the Apollo programm wasn't European either, the one that invented printing must have been American and your ancestors were natives....

Untrue. This only happens if you use absolute font sizes. If you use em or ex, for example, it still scales.

Sorry, man you also got the conversion rate for the German Mark wrong. It's 1.95583 Marks per Euro.
Microwave power plants? I remember those from Sin City... the beam never really went where it was supposed to and burnt down half of my town...
