"“Dr Rubbia says a tonne of the silvery metal – named after the Norse god of thunder, who also gave us Thor’s day or Thursday - produces as much energy as 200 tonnes of uranium”" =================================================

very good question epithermal as we all know the hype media or unscrupulous corporations have been known to use.

I would say that based upon the minimal waste and the claimed higher efficiencies of the proposed high temp. turbines most of this claimed efficiency can be realized. If you use more of the fuel supplied your process is more efficient.

It is certainly a number to be challenged.

I see your point. It is not just the energy in the thorium, but the difference in efficiencies of the reactors. I will have to study this more when time allows.
