Actually the best alternative I've seen thus far is synfuel from coal with thorium producing the process heat.

You've mentioned this in other Tickers, but I can't remember if you've stated a "price of oil" where this becomes economically viable, especially since it will require quite a bit of new infrastructure. (the thorium reactor plants, etc.)
Where would this become economically viable vis-a-vis oil price?
I assume current transportation infrastructure....cars, filling stations, etc. would not need modification.
Thanks.
