Let me tell you all the Pros and Cons of DT fusion and He-3 fusion.

~Common Pros~ No pollution, no risk of a meltdown, no toxic waste.

~DT Fusion~
~Pros~: Sources are nearly limitless as they are water and lithium. Since tritium can be acquired by bombarding lithium with neutrons you can make the tritium fuel on site.
~Cons~: Neutron radiation is VERY hard to stop/block. You either need to ship lots of water/deuterium to the site or build it near the water.

~He-3 Fusion~
~Pros~: No neutron radiation so the reactors are cheaper/easier to build. Unlike DT fusion He-3 fusion only requires one ingredient so the shipping cost/emissions are lessened.
~Cons~: Ummmmmmmmm the only way to get He-3 is to mine on the moon............ :|

My outcome: DT fusion! Even though the reactors may be more expensive and shorter lived going to the moon is VERY expensive and VERY NON cost effective so unless we make some sort of 'super spacecraft' we aren't getting anywhere with He-3 fusion!

Hope that cleared some stuff up :) ! I support as well Bump!

The problem is that the government officials only listen to their superiors so they don't get booted off the job and the 'head honchos' only care about saying what is 'right' for them they couldn't care less about the 'unimportant' environment and these scientists are going "HEY HEY!!!" and they just don't care. (Political Idiots if you ask me)

They only care about what makes THEM money so help via the government is almost hopeless.

I read something on muon-catalyzed fusion. Requires 270 times fewer energy compared to DT fusion. The only problem is that muons are very short-lived and are used up after a few hundred fusions. And we don't have a reliable source of muons yet.

Personally I think this "global warming" is not a big deal as it seems to be. This doesn't mean I don't think there are environmental issues. Water pollution and atmospheric pollution are problems in some parts of the world. However, global warming requires at least two-hundred years of evidence of rising global temperatures. We only have about one-hundred and twenty-five at best. And until the 1970's, we only had land measurements, not satellite measurements. Land measurements only gave us teperatures in large cities, not deserts, oceans, or arctic regions. However the evidence would seem to suggest there is a warming trend over the past decade, but only by a few degrees Faerenheit. And since pollution has gone down since the 1970's, that would seem to suggest the warming trend is natural.

Thunder, it is a big deal. It is as bad as the IPCC says it is, if not worse. We do have more than enough data to make accurate predictions about the state of the climate.

Exaggaration is simply not welcome in peer-reviewed literature.

Thunder does make a point.
I recieved 'The Skeptical Environmentalist' by Lomborg yesterday. It's a very good book.
Lomborg argues that long-term trends are more important than short-term ones. Many false conclusions have been drawn based on short-term trends. For example, Lester Brown predicted in 1993 that grain yields reached their maximum and would slowly decline, based on a short decline from 1990 to 1993. Grain yields continued increasing though.


He didn't say problems are being solved. The state of the world is getting better, but it's still bad.
