The Liquid Fluoride Thorium Paradigm

The Liquid Fluoride Thorium Paradigm
My origional Oil Drum post, and its 456 comments can be found here:

Many of the Oil Drum comments, did not raise the usual objections to nuclear power. Rather it was the consequences of a successful Thorium paradigm that bothered the commenters:

An excellent article and probably about the most promising alternative energy source that exists today. Failing the development of controlled nuclear fusion, thorium breeder reactors would appear to be almost as good in terms of fuel security and environmental impact. Unfortunately, the more useful an energy source is, the more that it permits the exploitation of other resources and thus damage to the environment. That is after all, exactly what harnessed energy sources are intended to do.

This discussion brings us back to the problem that we live within perpetual growth machine, on a finite land space, with finite material and biological resources. We therefore face the problem that giving human beings a fantastic new energy source, would allow growth based economic systems to reap even more damage on the planet. This is a fundamental problem with any living system that grows within a finite environment. It can either choose to reach a stable state, or it can continue to grow until every resource is consumed and die off like bacteria in petri dish. Unfortunately, a cooperative Power Down or species-wide self-limitation would appear to be impossible in the present global political environment. The only way out of this paradox is for humanity to collectively agree to reduce population size (as China has taken steps towards achieving) and allow continued per capita economic growth. This would allow individual living standards to expand even as total GDP remained static. Gradual progression of technology, the development of compact agricultural systems, car-free cities, integrated waste management, etc, would allow environmental impact to gradually decline. Such a development would require the leadership of a body like the UN.

Ultimately, growth would appear to be an endemic characteristic of all living species and is only held at bay by physical restraint. This does not bode well for a species that is limited to the surface of only one planet. For this reason I think that anyone within post-oil community that still clings to the idea of economic growth or even technological growth for humanity in the future, either hasn't thought the problem through and is relying upon blind hope, or must be a space travel enthusiast.

The thorium electricity is clean for all practical purposes. A clean, abundant power source will enable us to do more with less resources and less pollution.

False. If you study some demographics you'll realize that urbanization and industrialization leads to much reduced nativity. In much of Europe, the population pyramid is inverted. Also, rich countries have all implemented stricter environmental standards, which poorer countries can't afford.

We can argue about the distant future, but for now, growth and tech is the only hope for humanity and the Earth. Without growth and tech, the population increase won't stop at the projected 9-10 billion, environmental standards won't continue to improve, and all available resources will be utilized by increasingly desperate peoples until collapse. The only way to go is forward, and I'm saddened that you and others strive in the opposite direction, putting your hope in authoritarianism and socialism, which have always proved counterproductive in the real world.
Jeppon's comments were important contributions to my essay.

"putting your hope in authoritarianism and socialism, which have always proved counterproductive in the real world."

I'm a Thorium energy enthusiast like yourself, but, in my opinion, it's a mistake to always put together authoritarianism and socialism.
Police states can exist in any economic system, not only with "socialism", whatever you exactly mean by that.
For example, the United States is capitalist, but we live under a survelliance system the Stasi in East Germany could only dream about.

Ignoring the fact that we are a very long way from "post oil" I am pleased to see that even this Luddite acknowledges that their "only one Earth and when we have used it up will have nowhere to stand" is rubbish unless we ban human progress in space. He is, of course, wrong unless we ban human progress here to - which is obviously what the real ecofascist agenda is.
