The Greeks have already crushed their economy. I think you got it right. Hopefully, The Greeks also have an underground economy. On the one hand, this is probably a reason why the other economy crushed but, on the other hand, that will probably help them in tough times. Strange. The initial problem...

Changing a transportation infrastructure is a long strategic move. I do not think you can actually demonstrate its economic viability prior to the move because so many interdependent parameters are affected. A typical system problem. The USA has invested in air travel so much and for such a long tim...

I like the concept, but I just don't think it's practical here in the US. The only reason I see why the USA have not developed a high speed train infrastructure is the federal nature of the country which makes it difficult to agree on such large interstate initiatives. Population density indeed is ...

So am I. Hydro need mountains and streams. You have them or not. In my life I have seen so many economic studies demonstrating everything and its opposite. I do not trust any unless I am given every detail of the calculation so I have a chance to guess what they chose to conceal and whose pawns they...

Sodium cooled reactors were build in UK, France, Russia, India, Japan and even Germany. Superphenix, a 1300 MWe protoype reactor was operated in southern France between 1986 and 1997, then stopped for political reasons. As a prototype it suffered from several minor incidents, but the fact that it wa...

No fusion involved here at the end of the day. It appears that the Times journalist has totally mistaken the sodium fast breeder which the CEA and AREVA actually plan to build for the fusion-fission hybrid reactor which is studied at the University of Texas at Austin. Science journalism is not what ...

The Times referred to research conducted at the University of Texas at Austin as similar to AREVA's project. The Science Daily recently published an article about UT's research project. Their fusion-fission reactor is based on a tok. Based on the the drawing, it is difficult to describe its shape as...

I still do not understand where the Th230 will come from, as blaisepascal already asked. It can be obtained from the alpha decay of U234 or Pu238.
You will find some from LWR spent fuel but this is going to take a lot of time.

Bill Gates & the Traveling Wave Reactor at TED

Bill Gates gave a talk at the TED Conference . His speech is based on avoiding CO2 emissions (which may be flawed or may be not) rather than finding a solution to fuel scarcity. More comments can be found on CNN Tech . Gates introduces the TWR which he sponsors through Terrapower. This nuclear fissi...

Back to the topic, see how the spirit of resistance can still find its way. I also strongly encourage the (unexpensive) reading of Persepolis by Marjane Satrapi. This may give a hint as to how things have a chance to get better in Iran, however long it may take. Iranian officials mentioned a soft wa...
