Yes. Look at what Global Thermostat is doing with their technology research into carbon reclamation. AFAIK they have tech that can make power plants carbon negative and its simply a matter of getting the stuff cleared and mass-produced. This way at least we can keep economies going while we search for more feasible/permanent solutions rather than needing to get draconian.


And...

thorium reactors, no question.

they cant have a classic meltdown, they produce little waste and they are small cheap and simple compared to regular nuclear reactors.


Now that's more like it. :D

The emission should be curving now that aliens crossing the border are slowing down.

Just curious, but since the highest sources of CO2 emissions are heavy transport, energy generation, heating, and industry, can anyone propose any practical alternatives instead of engaging in gratuitious finger wagging over who puts out the most carbon emissions?


Yes. Pave North America from coast to coast with fast breeder reactors and thorium reactors. Split atoms, not wood. When we generate our electricity by means of turbines spun by steam produced by nuclear powered heat we have licked the pollution problem, broken the filthy oil habit and assured ourselves of centuries of clean energy.

hmm does fast breeders allow for medical isotopes?

the largest issue in denmark at the moment in the medical field is a shortage of medical isotopes for imaging, driving waiting lists to be longer than our legal limit.
5 years ago they closed the risoe experimental breeder responsible for producing denmarks own supply (and export what was left to our neighbours)

Only if you don't throw them in the breeders. You can get medical isotopes by using small quantities of primary fissiles to produce them. The real thing is heat, energy. That is what boils water and turn turbines to produce electricity.

China is making much more air pollution than the U.S. The U.S. is a good thirty years ahead of China in the matter of controlling pollution. The air in Bejeing is so thick it can be cut with a saw. The Bejeing pollution is much worse than L.A. is on its worst day.

In 2009, there were only 47 motor vehicles per 1,000 people in China (source). Whereas in the USA, most families own two cars or more.


Conveniently ignoring the fact that China has the dirtiest electric generating plants in the industrialized world. The Chinese do not use pollution suppression devices on their coal fired electric plants. That is why the air in the cities is so dirty. But the air out in the farm country is fine. Its just that the people out there make less then 2000 dollars a year. China = 300 million living in industrial (if polluted) splendor and one billion living as impoverished peasants.

Exactly the point.


China is at the stage we were at 200 years ago when we started our industrial revolution. They have the same amount of concern for the environment that we had 200 years ago- zero.

They cant afford the luxury of environmentalism- or think they cant.

They have to attract capital or generate capital to industrialize and are reluctant to put legal roadblocks in front of that- like environmental laws.

But unlike the USA which was a tiny patch of settled land on the edge of an empty wilderness two centuries ago: china is already a crowded continental sized country. So its to be expected that they would have more pollution for every dime increase in thier GNP than we had even 200 years ago.

In fact china is more crowded than Britian was when the British started the industrial revolution before it spread to the USA.
In fact China is more crowded than post industrial britan is today.

Another factor is the change in the USA economy.
The USA has less air pollution than china because even today we have a fewer people dispoiling a bigger nest than china has. And it is true that we have better polution laws that are better enforced than do the chinese. But there is another factor. Much of the airpollution in china is in fact American pollution.

America is de -industrializing.

We used to pollute our own air in order to make our own consumer goods.

But now were sending all of our smoke stack industry jobs overseas to places like- China!

So now we hire the chinese to pollute china's air to make OUR consumer goods. The location of the smoke stacks is all that has changed. If we kept the jobs here we would have a lot more air pollution despite our better laws. Thus the great strides our country has made to reduce its share of the world's pollution in recent decades are NOT such great strides after all. And the Chinese are crucifing thier lungs for our sins- to some degree.

It doesn't help that Canada is a major world supplier and things haven't been going so well for us. The NRU reactor which produces the majority of the world's medical isotopes is, to be perfectly honest, too old to continue operating. Our nuclear regulator forced it to shut down a few years back but, scarily, the Prime Minister ordered that it be restarted and fired the head of the regulator. The NRU should be shut down and replaced. Unfortunately, for reasons that I am not clear on, the MAPLE reactors meant to replace it for isotope production have been cancelled. Which is too bad, because there would have been two of these reactors, either one of which could have met world demand.
