I have a question about that, actually - I read in an article in Chemistry over the summer that the fuel rods are "depleted" when they are down to something like 90% (or was it 97%). Wouldn't it be possible to, instead of using rods, dissolve it into the water in the reactor, and periodically purify it? It would seem that would reduce waste a lot and make the fuel last a lot longer. |
What they mean is the rod have too many impureity than need to be reprodust at than plant which extact the impure out of it like weapon grade Pu-239.

The weight different isnot really that big to allow easy seperation of the two. The chemical prop of the Isop are the same as the some of the phyical prop are also. It than long involute worked to seperate then. Pu is very flameable and can inite itself on fire very easy. Pu is than very toxic metal which it you cut your finger on it they need to right way cut your entire arm off to save your life. Pu give off gamma radiation also.

The air pollution of most cars is photochemical smog, these days, as people are getting less and less sulfur in their cars. Particle pollution is also a problem, but can be fixed with filters. The big problem is the Greenhouse effect created by the CO2. Some details: Gas cars WON'T solve the problem. while pollution will be close to zero, with no Sulfur in gas, and NOx levels to be fixed through more fine-tuning of the fuel-air mixture, the greenhouse effect will stay, through the immense inneficiency of internal combustion engines. In such conditions, fuel-cell engines, refueled through plugging into electricity at night, for example, even such that is produced through fossil fuels, will cause a dramatic decrease in CO2 output levels, since the CO2 output by cars will practically disappear from the equation. That happens since by refueling through the night, you're actually using an unused capacity of the fossil fuel power plants, that run "on neutral" through the night, as demand plummets. In this way, we'd be actually saving a lot of energy completely wasted otherwise.
This is, however, only an intermediate solution. The true solutions lie in Fuel cell cars powered by electricity for fusion.
Some would point out that I forgot about the renewable sources. well, I support using renewable sources whenever possible, like Hydropower or tidal power where possible. I do not believe in subsidizing green electricity, however. Cheap energy is possible, when we'll break the fusion problem. Investment in other green technology, unless it's really about to produce a sizeable chunk of our electricity, is futile.

Because there is lots of pollution in the United States. I don't blame you for your ignorance on the subject but I would like to help inform you.
http://www.rtknet.org/
This right to know network lists violations of pollution laws for companies in the United States wherever you live. Enter your city state zip code etc... There is also a case list of settlements over such incidents. There are a lot of companies who continue to commit gross violations of pollution laws, in which penalties are not enforced.
I remember a story about a city 50 miles south of where I live, in which they uncovered that a hospital had been dumping medical waste in a lake, including needles, blood products, and other hazardous materials. A 10 year old boy stepped on one of these needles, and got gangreen, the doctors did not succefully treat it and he lost first his leg and then his life. The Hospital swears that it hadn't been dumping such materials, so a group of several hundred volunteers got rubber suits and literally dug out several dump trucks full of crap the hospital had dumped, and they dumped it on the front lawn of the hospital, until eventually the hospital agreed to clean up its mess. I don't remember if a lawsuit was successful by the familty of the child that died. This happened in Rutherfordton, North Carolina, just a few years ago. This kind of stuff is routine, and happens all the time.
A contractor for a local hospital in my city was incorrectly disposing of abestos by burying it in the forest.
I know you don't want to hear any of this, but this stuff is not too hard to find if you only look for it. Try to be more informed, or continue knowing what you want to believe.

Sava, I've been pro environment all along.  It's you baby killers and anti military wimps that keep me firmly on the right. 
Spiffor, Defiant, people should not be free to harm other people by their actions. Consider the anti smoking laws... I'm all for em. I should be free of some idiot poluting the air I breath. Also, the people living in those South Pacific islands that are going under water would still have a home if it weren't for polluters. Are those people free? I'm for personal responsability. We need to clean up our act and quit whining about it.
Defiant, I don't expect you to willingly give up your 4x4. I just expect you to give it up.  |
Lancer,
I don't want people hurt either, however, where does it stop, McDonalds kills people, cars kill people, drinking kills people, NASCAR kills people, guns kill people, heating homes with oil kills people, basic industry kills people........................ so tell me where does it stop. I will tell you where, guys like Sava and Spiffor want us riding our bicycles, wearing black pajamas with funny little hats singing kum by ya my love, with our freedom being dictated to by MR. Hillary Clinton. That may be the Euro/communist way but I guarantee most Americans will not stand for it, so pound away, all you will be doing is pounding sand.
BTW, in China they have a shortage of heating fuel oil, so people are heating their homes with human/animal crap, they are calling the goldish/brown haze from it, a toxic killer cloud(no pun intended). I think you really need to focus on reality and not utopia. This isn't a perfect world yet and at some point our engineers will be able to make my Dodge 4x4 without any pollution to the air or water but until then I am not about to ride around in a Yugo just to make you guys happy.

Hmm... better home insulation, more efficient heaters, smaller homes are why Europe uses less power than US.
Leaving the car out of it for a while.
More use of wind and wave power!

I'm also for public smoking bans... but not the fascist ones that the government is imposing on PRIVATE businesses.
