This is a 40 minute video discussing energy economics, specifically WRT Thorium. I started to hijack the recent solar power thread, but decided against it.

A fine bit of hijacking it was, too! OD offers opportunities for free education with remarkable frequency. I didn't know about the thorium reactor and I learned a lot from the links and further searching.

Good good. IMO molten salt reactor tech is more likely to positively influence the world's energy (and political) problems than anything else that I am aware of. Not many people like to talk about it though. I'm also glad to hear of Chinese progress on it, for a couple of reasons.

1. They must use nuclear. No other energy source comes close to meeting their projected growth in demand.
2. LWR's (current tech) are finicky, and need a lot of well trained baby-sitters. That kind of thing can't scale well.
3. We're down-wind of any probable nuclear accidents.
4. If they used coal, we'd be worse off pollution-wise than with periodic Chinese nuclear accidents.

5. Burning coal releases a fair quantity of radio-isotopes into the environment.

Coal is a thor loser?

Nice one!

Yeth. That theem to be the cathe.

CO2 remains a great plant growth accelerant.

"If you dont have time to do it safely, you dont have time to do it"

"The democracy will cease to exist when you take away from those who are willing to work and give to those who would not."

That's true. I'm aware of a series of greenhouse experiments in which Spartina (a saltmarsh grass) grows more vigorously with elevated CO2 & temp.

A downside of CO2 & temp increase is lower O2/CO2 ratio in the ocean. This is bad for life. In the Triassic (IIRC) this shift led to a few million years of anoxic oceans and low O2/CO2 atmosphere in which most living creatures could not live above sea level due to lack of oxygen.

There is more that we don't know about climate than we know. Today is a good predictor of tomorrow, but not perfect.

On the a closely related topic, following is a long video of an informal presentation on so-called moving wave technology. Both this and Thorium based reactors as shown in the previous video are being investigated by B. Gates and developed in China. This video goes into far more detail than the other.

But of course, this technology has ZERO chance of attaining maturity without government interference and funding.

If the market place is left as the motivation to innovate, things like this will INDEED obtain maturity.

Great response!
Of course it does open the question of what is in your mind that you made that connection. It must be a strange place, indeed. ( Not a criticism--I still suffer from some form of attention deficient disorder--As I told my similarly affected son--its a 2-edged sword--sometimes you will lose people as you make what seem to you to be normal transitions in a conversation but others don't can't follow them., OTOH, those same sorts of leaps enable you to seem very creative.) Was that an example of what happens?

Here is the solution to our energy needs:

Rats--can't post the picture--look at yesterday, and today's "Pearls before swine" comics.

I've read the opinion that uranium has been generally favored over thorium because of the desire to portray nuclear bomb tech as something positive for the world. Harnessing the atom and all that. That would still have to be somewhat true with thorium but apparently it doesn't offer the same propo score.

A buddy on another site is a booster for life of the integral fast reactor (IFR) for which there is apparently no other available suitable coolant/energy transfer medium than liquid sodium. I'll admit it's an attractive solution in many ways - it could consume much of waste nuclear materials currently in haphazard storage and is allegedly meltdown-proof. The downside from what I can gather is that so far practically all of them have suffered debilitating sodium fires. What could go wrong? Liquid sodium separated from water by a thin metal membrane? Oh boy. Maybe if the sodium could heat another medium which is then transferred to the water/steam component - sort of a buffer step - might be more reliable.
