Angilion, save your breath when it comes to arguing with Crakrjak. This is the bit where he ceases to comment further, because he's already been rightfully placed into a corner as a scientifically illiterate dickhead.

Thallium-208 is one of the arguments in favour of using thorium for fission because it reduces the chance of nuclear terrorism. You can't do it on a small scale, as a terrorist group would have to, because it decays into such a powerful gamma emitter. Even if you have suicide workers who are willing to die from the radiation exposure in order to build a bomb, your facility will be easily detected. Moving the material would also be much harder for the same reason.
I think your thorium fission power station small enough to go on a tractor trailer is impossible as a result. I think you just couldn`t shield it well enough in that size. Gamma radiation in the MeV range takes a lot of stopping.

Angillion: Thallium-208 is way way down the decay scale. In fact it hit stable lead before it turns into Thalium for a couple of minutes. Since lead is in and of itself a radiation shielding material, I don't see a problem there.

Oh, and about Washington state...
They're generating a smallish minority of their electricity from wind power.
It isn`t free - it`s very expensive.
It isn`t their sole means of generation, or even a large part of it.
It is never planned to be, because they employ people who understand power generation.
What I said about CSP applies to other renewables too, in different areas. CSP in hot uninhabited areas, wind in windy uninhabited areas.
CSP is appropriate in some areas, if you back it with a cutting edge HVDC grid (which is very far indeed from free) and you retain a large *controllable* generating capacity to maintain constant matching of supply to demand.
Unless someone comes up with an efficient way to store GWhs of electricity, renewables can`t be the main generating method, let alone the only one, even if we`re willing to eat the cost and environmental impact.
