New Umbrella Terms needed: NU2CLEAR and NuGen2 (for Thorium & IFR)
Thanks @YetAnotherBlob for the informative comment. It justifies itself as a miniarticle for the information in contains. It really show how well-learned you are.
However, I am afraid many of the readers here have missed out on the hidden nuggets of wisdom. Maybe someone (lika an editor at smartplanet), should expand and explain the terms, or the background facts (such as how the Ricther Scale works), that you have taken its understanding among the public for granted.
Along these same lines, be it IFR or Thorium cycle, the general human psyche do not care for scary names that carry an old stigma. Look at this problem from a pyschological perspective. Give these technologies a NEW UMBRELLA NAME. Something like "Nu2clear" or "Nu Gen 2" Technology. History has shown us that human beings need to be rushed into a new era via symbolic totems.
(And form the proverbial carrot and sticks: Begin to market and subsidize these "NuGen2 technologies" as we outlaw classic "nuclear technologies". Every switch involves labour pains, but always better to move than to suffer afterwards.)
