I think most of you were missing the point of this topic. There is a cheaper, and FAR safer nuclear reactor that is extremely difficult to make weapons with. It is the Liquid Fluoride Thorium Reactor (LFTR). Thorium is 3 times more common than Uranium and when chemically reacted with Fluoride it becomes a liquid. Meltdowns will not be an issue because the fuel is already a liquid. If the fuel gets too hot, it turns into a gas, expanding causing the molecules to move further apart, slowing the reaction down. And if it's still too hot the molten sodium valve melts open sending the fuel to a drainage tank lined with neutron absorbers causing the reaction to stop. This reactor is walkaway safe.
And yes, there are waste products, but even these can still be useful. One of the byproducts is the same isotope that is heating the earth's core making geothermal energy possible, as well as the source of energy of spacecraft that are too far for solar energy to be useful (like the Voyager spacecraft).
I have to say I like the concepts of improving the retention and effectivity of the photovotalic-cell due to the ubiquity of solar energy. Also a synergistic approach just sounds ultimately more efficent. The solutions span from pressure power from roads (think about that being installed within side walks and highways...it could convert expended ATP and hydrocarbons into kinetic energy to spin a series of small generators) to geothermal, to this supposed thorium and reknewable carbon . The best option is a diversity of options. We should never put all out eggs in one basket. It's what we've done with fossil fuels, and in hindsight as with all inventions we have realized it truly isn't a panacea for all our woes.
Everything looks nice on paper, even communism...and that was a disaster and a half. Atomics International has used thorium-floride compouns that are sodium cooled before, and it caused one of the aforementioned meltdowns we have been discussing. This has aroused some suspicion... I can't just be uncritical to this design, Louis. This guy works for a company that wants this to happen and profits from such, there is very well a chance that he's not giving the full story. Let's not buy this possible snake-oil just yet by watching one youtube video, okay? Let's be critical thinkers. I would want to hear from more than just this one man on the implications of thorium. There could be detractors out their as well that carry some authorative weight and some valid points to make. As for me, I will readily consider it one option...but it's not, nor it will be ever the sole option to this complex and dynamic problem.
You should do your homework on this some more. Give us some more syntopical sources, then we can draw a more valid synthesis of a consensus on this method of power-production.
And if this is true...After you've done your journalistic homework and seen if this indeed valid You need to invest some stock money in thorium! It will make a rich man. He who controls the thorium-mines...controls the economy. You could build all the planes you want.
